Requirements

Trend Graph Rendering
"As a shift-based clinician, I want to view an interactive trend graph of key vitals over the past 48 hours so that I can quickly assess patient status at the beginning of my shift."
Description

VitalVista shall render intuitive, interactive trend graphs displaying key patient vitals (e.g., heart rate, blood pressure, oxygen saturation) over the past 24–48 hours, with smooth zoom and pan capabilities. The graph will automatically highlight timestamps where vitals cross critical thresholds and support tooltips for precise readings. It will integrate seamlessly within PulseLink’s patient dashboard, enabling clinicians to quickly visualize patient status upon shift start.

Acceptance Criteria
Graph Initialization on Dashboard Load
Given the patient dashboard is opened by a clinician at shift start, when the trend graph component receives valid vital data for the past 48 hours, then the graph loads within 5 seconds and displays distinct, correctly labeled lines for heart rate, blood pressure, and oxygen saturation along the appropriate time and value axes.
Interactive Zoom and Pan
Given the clinician performs a zoom or pan gesture on the trend graph, when the interaction occurs, then the graph responds within 200ms, smoothly adjusts the time range, and allows navigation across the full 24–48 hour window without data gaps or rendering artifacts.
Critical Threshold Highlighting
Given vital readings cross predefined critical thresholds (heart rate <60 or >100 bpm, systolic BP <90 or >180 mmHg, SpO2 <90%), when the graph displays these data points, then each critical point is highlighted in red with an asterisk marker and is included in an autogenerated summary list.
Precise Tooltip Display
Given the clinician hovers or taps on any data point in the trend graph, when the interaction is detected, then a tooltip appears within 0.5 seconds showing the exact timestamp (HH:mm, MMM dd) and the precise vital reading value.
Seamless Dashboard Integration
Given the trend graph is embedded within PulseLink’s patient dashboard, when the dashboard layout changes (desktop, tablet, mobile), then the graph resizes responsively within 500ms, retains full interactivity, and does not overlap or distort adjacent UI elements.
Threshold-Based Alerts
"As a care coordinator, I want the trend graph to highlight critical threshold breaches so that I can promptly identify and escalate concerning patient vitals."
Description

The system shall automatically detect and highlight when vitals exceed predefined critical thresholds on the trend graph, using color-coded markers and summary callouts. Clinicians will be able to configure threshold values per patient or vitals type. Alerts will be integrated with PulseLink’s notification center to ensure immediate awareness of dangerous fluctuations, enhancing response times and patient safety.

Acceptance Criteria
Heart Rate Threshold Exceeded Alert
Given a patient’s heart rate reading exceeds the configured critical threshold, when the clinician views the 24-hour trend graph, then the breached data point is marked with a red icon and a summary callout displays the timestamp and value.
Custom Threshold Configuration
Given the clinician accesses the patient’s vital settings, when the clinician sets or updates a critical threshold value for a specific vital sign, then the new threshold is saved successfully and reflected on subsequent trend graphs immediately.
Threshold Alert Integration in Notification Center
Given a vital sign breaches its critical threshold, when the system detects the breach, then an alert containing patient ID, vital type, breached value, and timestamp is delivered to PulseLink’s notification center within 5 seconds.
Multiple Breaches Highlighting
Given multiple vital readings exceed their thresholds over a selected period, when the clinician views the trend graph, then each breach is displayed with a distinct color-coded marker and grouped into a summary panel sorted by severity.
Alert Acknowledgment Logging
Given the clinician acknowledges a threshold alert from the notification center, when acknowledgment is submitted, then the system logs the acknowledgment event with user ID and timestamp and updates the alert status to “acknowledged” in both the notification center and trend graph summary.
Data Aggregation and Normalization
"As a clinician, I want vital data normalized and aggregated over the past 24–48 hours so that I can rely on consistent graphs for my patient assessments."
Description

VitalVista shall aggregate raw vital sign measurements from disparate sources (monitors, EHR, wearable devices) over the selected timeframe, normalize data to a consistent scale and sampling rate, and fill gaps with appropriate interpolation. This ensures smooth, accurate trend visualizations and eliminates data noise or irregularities, providing clinicians with reliable and consistent information.

Acceptance Criteria
Multi-source Data Aggregation
Given the system is configured with multiple data sources, when retrieving vital signs for a patient over a selected timeframe, then all measurements from monitors, EHR, and wearable devices are collected without loss or duplication.
Consistent Data Scaling
Given raw vital sign values from different sources, when normalizing the measurements, then all data points are converted to a common unit and scale with zero value deviation across sources.
Uniform Sampling Rate
Given vital sign data with varying timestamps, when resampling for trend graph generation, then data is interpolated or aggregated to a uniform sampling interval of one measurement per minute.
Gap Filling via Interpolation
Given missing data intervals exceeding two consecutive sampling periods, when interpolating, then the system fills gaps using linear interpolation without generating values outside the patient’s physiological range.
Noise Removal and Outlier Management
Given raw vital sign data containing spikes, when applying noise filtering, then measurements deviating by more than two standard deviations from the rolling mean within a five-minute window are identified and either corrected or removed.
Time Window Customization
"As a clinician, I want to switch between different time windows on the trend graph so that I can focus on critical periods of patient data."
Description

The feature shall allow clinicians to adjust the time window of the trend graph dynamically (e.g., 6h, 12h, 24h, 48h) and automatically update the display. Customizable presets and quick-select buttons will enable rapid switching between views. This flexibility ensures clinicians can focus on pertinent periods of patient data without navigating away from the dashboard.

Blood Pressure Variability Identification
Given patient systolic or diastolic blood pressure readings fluctuate by more than 15% within one hour, When the system’s predictive analysis confirms significant variability, Then an alert surfaces in the snapshot view within 10 seconds including patient ID, metric values, and fluctuation percentage.
Real-Time EHR Data Integration Validation
Given new vital sign entries are recorded in the EHR, When the data feed updates, Then the predictive algorithm processes the new vitals and updates trend analysis within 30 seconds of data availability.
Snapshot View Alert Rendering
Given one or more predictive alerts are active, When the clinician opens or refreshes the snapshot view, Then alerts appear at the top of the snapshot ordered by severity and include patient ID, metric name, trend summary, and timestamp.
Alert Acknowledgement and Escalation
Given an alert is displayed in the snapshot view, When the clinician acknowledges it, Then the alert status updates to “Acknowledged” with a timestamp. If not acknowledged within 5 minutes, Then the system escalates the alert to the care team lead and records escalation time.
Critical Task Overdue Alerts
"As a care coordinator, I want to be alerted when critical tasks are overdue so that I can follow up and ensure essential patient care tasks are completed on time."
Description

The system monitors assigned critical tasks, such as medication administration or lab sample collection, and alerts care coordinators when tasks exceed their expected completion windows. Notifications appear in the snapshot with task details, elapsed time, and recommended actions, ensuring timely completion of critical workflows. This feature integrates with the existing task management module to improve task adherence and reduce clinical delays.

Acceptance Criteria
Overdue Medication Administration Alert
Given a medication administration task with a scheduled due time, When the current time exceeds the due time by more than 5 minutes and the task status remains 'Pending', Then the system generates an alert in the snapshot displaying task ID, patient name, medication name, scheduled time, elapsed delay, and recommended action, and the alert remains visible until a care coordinator acknowledges it.
Late Lab Sample Collection Notification
Given a lab sample collection task assigned with an expected completion time, When the current time exceeds the expected time by 10 minutes and the task status is not 'Completed', Then the snapshot displays an alert including sample type, patient ID, scheduled collection time, elapsed delay, and recommended action, and logs the alert generation event.
Missed Vital Signs Check Warning
Given a scheduled vital signs check at a defined interval for a patient, When the current time surpasses the last recorded check time plus the interval by 5 minutes and no new vital signs entry exists, Then the snapshot shows an alert with patient name, type of check, scheduled interval, elapsed delay, and recommended action, and highlights the alert in red.
Delayed Critical Procedure Reminder
Given a critical procedure task with an assigned due time, When the task remains incomplete 15 minutes past the due time, Then the system triggers an alert in the snapshot with procedure name, due time, current delay, and a recommended priority escalation, and sends a push notification to the care coordinator.
Escalation to On-Call Supervisor for Unaddressed Alerts
Given an overdue critical task alert is generated, When the alert remains unacknowledged by the assigned coordinator for 10 minutes after generation, Then the system automatically escalates the alert to the on-call supervisor with task details, patient information, original assignment, and elapsed delay, and logs the escalation timestamp.
Contextual Alert Suppression Rules
"As an ICU nurse, I want to suppress non-critical alerts during scheduled patient transfers so that I only receive relevant notifications when I need them."
Description

The system enables clinicians to define rules that suppress non-critical predictive alerts during specific events, such as planned ICU transfers or scheduled procedures. This customization prevents alert fatigue by filtering notifications based on context metadata like location, procedure type, or clinician role. The suppression engine integrates with user profiles and schedule data to maintain alert relevance and reduce noise in high-pressure environments.

Acceptance Criteria
Planned ICU Transfer Alert Suppression
Given a clinician schedules an ICU transfer for Patient X with start and end timestamps, when the system evaluates predictive alerts for Patient X within that timeframe, then all non-critical alerts are suppressed while only critical, life-threatening alerts are delivered.
Scheduled Procedure Alert Filtering
Given a patient has a 'scheduled procedure' event tagged in the system, when predictive alerts are generated during the procedure window, then non-critical alerts matching the procedure context and clinician role rules are filtered out, ensuring only relevant critical alerts appear.
Role-based Alert Suppression for On-Call Nurses
Given an on-call nurse’s profile includes suppression settings for non-critical alerts during night shifts, when the nurse’s shift starts, then all predictive alerts below the criticality threshold defined for that role and shift are muted until the shift ends.
Exam Session Alert Mute
Given a clinician starts a patient exam session flagged in the schedule, when predictive alerts occur during the active exam session, then the system suppresses non-critical notifications tied to that patient and session metadata to minimize workflow interruptions.
Cross-Department Contextual Suppression
Given a clinician updates their active context from ICU to Operating Room, when predictive alerts are triggered after the context change, then the suppression engine applies OR-specific rules to suppress irrelevant non-critical alerts while still delivering OR-critical notifications.
Alert Escalation Pathways
"As a charge nurse, I want critical alerts escalated to the on-call physician if not acknowledged quickly so that patient safety is not compromised."
Description

The system implements multi-level escalation protocols for unacknowledged predictive alerts, automatically notifying secondary team members or on-call staff if the primary recipient does not respond within a configurable timeframe. Escalation rules can be tailored per alert type and severity, ensuring urgent warnings are addressed promptly. This feature leverages PulseLink’s secure messaging infrastructure to maintain audit trails and accountability.

Acceptance Criteria
Primary Recipient Notification Timeout
Given a predictive alert is generated and sent to the primary recipient, When the configured acknowledgement window elapses without a response, Then the system automatically escalates the alert to the designated secondary recipient and logs the timestamp of both the original alert and the escalation action.
Secondary Recipient Acknowledgement
Given an alert escalated to a secondary recipient, When the secondary recipient acknowledges the alert within their acknowledgement window, Then the system stops further escalations and records the acknowledgement event and its timestamp in the audit trail.
Custom Escalation Rule Enforcement
Given an administrator configures escalation rules for a critical alert with a specified severity and timeframe, When such an alert is generated, Then the system applies the custom timeframe and severity rules to trigger escalation according to the configuration.
Audit Trail Integrity
All escalation steps—including original alert dispatch, timeout events, escalation actions, and acknowledgements—must be recorded in an immutable audit trail and be retrievable by authorized users via the alert detail interface.
Configurable Escalation Channel Options
Given an alert type has multiple notification channels enabled, When escalation occurs, Then the system delivers the alert via all configured channels, retries failed deliveries up to three times, and logs each delivery attempt and failure.
Personalized Alert Priority Tuning
"As a hospitalist, I want to customize alert sensitivity for my patients so that I receive only the most relevant warnings for my current caseload."
Description

The system provides clinicians with controls to adjust sensitivity levels for different predictive alert categories, allowing personalization based on patient acuity, clinician preferences, or unit protocols. Changes update the AI model’s threshold parameters in real time and reflect across all devices. This feature ensures that alerts align with clinician workflows and reduces unnecessary interruptions in low-risk scenarios.

Acceptance Criteria
Sepsis Early Warning Threshold Adjustment by Clinician
Given a clinician changes Sepsis Alert sensitivity to 'High', When they save the change, Then the AI model updates its threshold within 2 seconds and subsequent sepsis alerts only trigger for deterioration scores above the new threshold.
Unit Protocol Compliance Configuration
Given a unit lead applies a 'Moderate' sensitivity preset for Medication Delay alerts, When the preset is confirmed, Then the alert sensitivity is set to 'Moderate' for all clinicians in that unit and a confirmation message is displayed.
Patient Acuity-Based Sensitivity Calibration
Given a patient's acuity level is updated to 'Critical', When the attending clinician selects the 'Critical' alert profile, Then all predictive alert thresholds adjust to the 'Critical' settings and the system notifies the clinician of the update.
Real-Time Threshold Synchronization Across Devices
Given a clinician changes any alert sensitivity on one device, When the change is saved, Then within 5 seconds all active sessions on other devices for that clinician reflect the new sensitivity settings.
Default Threshold Restoration After Shift Change
Given an outgoing clinician ends their session at shift end, When the session terminates, Then all customized alert settings revert to unit default thresholds before the incoming clinician begins their session.

When an emergency bypass session is successfully activated, Then the system sends real-time notifications to the designated surge administrator group via in-app alert and email, including clinician name, patient context, and activation timestamp.
Surge Threshold Auto-Trigger
"As a care coordinator, I want the system to automatically activate emergency access mode when patient load exceeds safe levels so that the right staff gain timely access."
Description

Automatically detect when patient load or critical event metrics exceed predefined thresholds and trigger the emergency bypass mode without manual intervention. This requirement includes real-time monitoring of patient census, alert generation, and automated access provisioning for relevant care team members. It enhances response speed and reduces the risk of delayed authorizations during high-demand periods.

Acceptance Criteria
Threshold Breach Detection
Given the patient census exceeds the predefined threshold of 80% for at least 2 minutes, when the system continuously monitors census data, then SurgeSafe bypass mode must be automatically activated without manual intervention.
Automatic Access Provisioning
Given SurgeSafe bypass mode is activated, when the bypass conditions are met, then all active and off-shift clinicians in the designated care team must be granted temporary system access within 30 seconds of activation.
Critical Event Monitoring
Given a critical event metric (e.g., Code Blue calls) exceeds the configured limit within a 5-minute window, when the system ingests and analyzes event streams, then SurgeSafe bypass mode must be triggered automatically.
Audit Logging Completeness
Given SurgeSafe bypass mode is active, when any user accesses the system under bypass, then each session must be logged with user ID, timestamp, session duration, and accessed resources, and audit logs must be available for review within 1 minute of session end.
Stakeholder Notification
Given SurgeSafe bypass activation, when the mode is triggered, then automated email and in-app notifications must be sent to the unit manager and compliance officer within 2 minutes.
Bypass Deactivation
Given patient census remains below the predefined threshold for a continuous 10-minute period, when the system monitors and confirms the condition, then SurgeSafe bypass mode must be automatically deactivated and temporary access revoked within 1 minute.
Time-bound Access Control
"As a system administrator, I want bypass access to automatically revoke after a preset time so that temporary access does not persist beyond its intended use."
Description

Enforce strict, configurable expiration for all bypass sessions to ensure temporary access is automatically revoked after a defined duration. The system must support variable time windows based on surge severity and role-based policies, issue countdown warnings to users, and log expiration events. This guards against prolonged off-shift access and maintains compliance with security protocols.

Acceptance Criteria
Surge-Triggered Temporary Access Expiration
Given a bypass session is initiated under a defined surge severity When the configured duration elapses Then the system automatically revokes the user’s access without manual intervention
Role-Based Duration Enforcement
Given a user’s role-based bypass policy specifies a maximum access duration When the session start time reaches the policy limit Then the system enforces revocation according to the role-based policy
Variable Time Window Configuration
Given an administrator updates the bypass session time window for a specific surge severity When a new bypass session is activated for that severity Then the session duration reflects the updated time window
Countdown Warning Notification
Given a bypass session is active with a configured warning threshold When the remaining time equals the warning threshold and again at one minute remaining Then the system displays countdown warnings to the user at both thresholds
Automated Expiration Auditing and Logging
Given a bypass session expires or is revoked When the system revokes the session Then an audit log entry is created capturing user ID, role, surge severity, session start and end timestamps, and duration
Multi-factor Authentication for Bypass
"As a clinician, I want to authenticate with a second factor when initiating emergency access so that patient data remains secure and only authorized users gain entry."
Description

Require clinicians to complete a two-step verification process when initiating or extending an emergency bypass session. This includes validating a secondary factor such as SMS code or authenticator app token, ensuring only authorized personnel can gain elevated access. Integration with existing identity providers and clear user prompts must be provided for a smooth but secure authentication flow.

Acceptance Criteria
Initiate Bypass Session
Given an off-shift clinician initiates an emergency bypass, when they submit valid primary credentials, then the system sends an SMS code to their registered mobile number within 5 seconds and grants bypass access only upon correct code entry.
Extend Bypass Session
Given a clinician’s active bypass session is within 5 minutes of expiration, when they request an extension, then the system prompts for a second factor (authenticator app token) and extends access by 30 minutes upon successful validation.
SMS Code Verification Fallback
Given SMS delivery fails, when no code is entered within 30 seconds, then the system prompts the clinician to enter an authenticator app TOTP token instead.
Authenticator App Token Validation
Given a clinician opts to use an authenticator app, when they enter a valid TOTP token, then the system validates the token within 10 seconds and grants bypass access if the token is correct and within its valid time window.
Identity Provider Integration
Given a clinician’s credentials are managed by the hospital’s identity provider, when they perform MFA, then the system completes secondary factor validation via the identity provider API and records the outcome in the audit log.
Comprehensive Audit Logging
"As a compliance officer, I want all emergency access sessions logged with user, time, and actions so that I can audit and ensure accountability."
Description

Capture detailed logs for every bypass session, including user identity, time of activation, duration, actions performed, and reason for access. Logs must be immutable, stored securely, and accessible via an audit dashboard with filtering and export capabilities. This requirement ensures full accountability, supports compliance audits, and enables post-event analysis of emergency access usage.

Acceptance Criteria
Activation of Emergency Bypass
Given a clinician initiates SurgeSafe Bypass during off-shift hours, When the session starts, Then the system records a log entry capturing user identity, activation timestamp, and reason for access.
Bypass Session Audit Data Integrity

Audit Dashboard Filtering and Export
Given the audit dashboard is accessed, When the user applies filters by date range, user identity, or access reason, Then only matching log entries are displayed within 2 seconds and are available for export.
Immutable Log Storage Validation
Given stored audit logs, When an attempt is made to modify or delete any log entry outside the system interface, Then the system rejects the operation and maintains the original entry unchanged.
Export of Audit Logs
Given a set of filtered log entries on the audit dashboard, When the user selects CSV or PDF export, Then the system generates a correctly formatted file containing all displayed entries and initiates a download within 5 seconds.

OffShift Alert

Instantly notifies IT compliance officers and shift supervisors whenever an off-duty user attempts to access protected chats or data. Real-time alerts help detect and address unauthorized access attempts before any data is compromised.

Requirements

Instant Off-Duty Access Detection
"As an IT compliance officer, I want to be instantly notified when an off-duty user attempts to access protected chats so that I can intervene immediately and prevent potential data breaches."
Description

Implement a mechanism to immediately detect any attempt by an off-shift user to access protected chats or sensitive patient data. The system should cross-reference user shift schedules with access requests in real time, ensuring unauthorized access attempts are flagged as they occur. This feature reduces the risk of data breaches by providing the first line of defense against unauthorized access outside designated work hours, integrating seamlessly with existing shift management modules and access control policies.

Acceptance Criteria
After-Hours Chat Access Attempt
Given the user is outside their scheduled shift hours, when the user attempts to access a protected chat, then the system verifies the shift status, flags the attempt as unauthorized within 1 second, and logs the event.
OffDuty Patient Data Access Attempt
Given the user is off-duty, when the user requests patient-sensitive data, then the system blocks access, displays an “Access Denied” message, and logs the user ID, timestamp, and resource requested.
Shift Schedule Modification Edge Case
Given a shift schedule update has occurred, when the user attempts access within the post-update grace period, then the system references the updated schedule and either permits or denies access based on the new shift times.
Real-Time Alert Notification Delivery
Given an unauthorized off-shift access attempt is detected, when the event is flagged, then the system sends alerts to IT compliance officers and shift supervisors via secure channels within 5 seconds.
Audit Log Integrity Verification
Given multiple unauthorized access attempts, when logs are stored, then they must be tamper-proof, include user ID, timestamp, resource attempted, shift status, and be retrievable for audit purposes.
Multi-Channel Alert Delivery
"As a shift supervisor, I want to receive off-shift access alerts via my preferred communication channel so that I can respond quickly even when I’m away from the main application."
Description

Provide configurable, multi-channel delivery of off-shift access alerts, including in-app notifications, SMS, email, and integration with paging systems. Administrators should be able to define preferred channels for different user roles and severity levels. This ensures critical alerts reach the right personnel in the fastest possible way, accommodating varied communication preferences and guaranteeing no alert is missed during high-stakes situations.

Acceptance Criteria
Default Channel Delivery
Given an off-shift access attempt is detected, when no custom channel preferences are set, then the system sends the alert via in-app notification to the default administrator channel within 5 seconds.
Role-Based Channel Configuration
Given an IT compliance officer is assigned preferred SMS and email channels, when they receive an off-shift alert, then the system delivers the alert via both SMS and email within 10 seconds.
Severity-Level Routing
Given an off-shift access attempt is classified as high severity, when the alert is generated, then the system concurrently sends notifications through paging system and SMS.
Fallback Channel Mechanism
Given a primary delivery channel fails, when the system detects non-delivery within 15 seconds, then it automatically retries sending the alert via the next configured channel within 5 seconds of failure.
Confirmation Acknowledgement Logging
Given alerts are dispatched through all configured channels, when each channel confirms receipt, then the system logs the confirmation timestamp for each channel in the audit log.
Configurable Alert Thresholds and Filters
"As a security administrator, I want to customize alert thresholds and filters for off-shift access attempts so that I only receive relevant notifications and reduce noise."
Description

Enable administrators to configure thresholds and filters for off-shift access alerts based on user roles, time windows, data sensitivity, and frequency of attempts. Settings may include minimum number of attempts to trigger an alert, specific data categories to monitor, and role-based exemptions. This flexibility minimizes false positives, ensures compliance, and aligns alerting behavior with organizational policies and risk tolerance.

Acceptance Criteria
Threshold Configuration for Attempt Count
Given an administrator sets the off-shift access attempt threshold to X, when a user attempts off-shift access fewer than X times within the configured time window, then no alert is generated; and when the Xth attempt occurs, then an off-shift alert is triggered.
Role-Based Exemption Filter Setup
Given an administrator marks specific user roles as exempt, when a user with an exempt role attempts off-shift access, then no alert is generated regardless of attempts; and when a user with a non-exempt role attempts off-shift access exceeding any configured thresholds, then an alert is generated.
Time Window Alert Filtering
Given an administrator defines off-shift time windows for each department, when a user attempts to access protected data outside their active shift hours, then the system evaluates the attempt against configured thresholds and filters and generates an alert if conditions are met.
Data Sensitivity Category Monitoring
Given an administrator selects one or more data sensitivity categories to monitor (e.g., PHI, financial records), when a user attempts off-shift access to data in a monitored category, then the system generates an alert if the attempt meets or exceeds the configured thresholds.
Frequency-Based Alert Aggregation
Given an administrator configures a maximum alerts-per-period limit, when multiple off-shift access attempts occur within the same aggregation period, then the system consolidates attempts into a single alert if below the alert limit, and generates individual alerts only when the limit is exceeded.
Automated Escalation Workflow
"As an IT compliance officer, I want off-shift access alerts to escalate to my backup if I don’t acknowledge them within five minutes so that there’s always someone responsible for handling the alert."
Description

Design an automated escalation workflow that routes off-shift access alerts to secondary contacts if the primary recipient does not acknowledge within a set timeframe. The workflow should support multiple escalation levels, customizable timeouts, and auto-closure upon acknowledgement. This guarantees accountability and ensures that critical alerts are addressed without delay, aligning with incident response protocols.

Acceptance Criteria
Primary Contact Acknowledgement
Given an off-shift access alert is generated and sent to the primary contact, when the primary contact acknowledges the alert within the configured timeout, then no further escalations occur, the workflow is marked as closed, and the acknowledgement timestamp is recorded.
Secondary Escalation After Primary Timeout
Given no acknowledgement is received from the primary contact within the configured timeout, when the timeout expires, then the alert is automatically escalated to the secondary contact, and a new notification is sent.
Tertiary Escalation After Secondary Timeout
Given the alert is escalated to the secondary contact and remains unacknowledged within the secondary timeout period, when the secondary timeout expires, then the system escalates the alert to the tertiary contact and logs the escalation event.
Custom Timeout Application
Given administrators customize the timeout durations for escalation levels, when a timeout value is updated in settings, then all subsequent alerts use the updated timeout durations for their respective escalation levels.
Auto-Closure on Acknowledgement
Given any contact acknowledges the alert at any escalation level, when the acknowledgement is received, then the workflow auto-closes immediately, no further notifications are sent, and the event is logged.
Comprehensive Audit Logging
Given any escalation action occurs, when alerts are generated, escalated, acknowledged, or auto-closed, then all events are recorded in the audit log with timestamps, user identifiers, and action types.
Comprehensive Audit Trail Generation
"As a compliance auditor, I want a detailed, unalterable record of all off-shift access attempts and alerts so that I can verify adherence to policies and investigate incidents effectively."
Description

Automatically log all off-shift access attempts, alerts generated, delivery records, acknowledgements, and escalations in a tamper-evident audit trail. The logs should include timestamps, user details, access context, and resolution actions. This audit trail supports regulatory compliance audits, forensic investigations, and continuous improvement of security processes.

Requirements

Comprehensive Event Capture
"As a security officer, I want all access events logged with precise details so that I can reconstruct user activity and ensure accountability during security audits."
Description

Capture every user and system access event related to patient data, including automatic locks, manual overrides, and bypass actions. Each event must be timestamped, tagged with user and device identifiers, and stored in an immutable ledger. Integration with PulseLink’s messaging module ensures that any access that triggers a lock or override generates an entry in real time, allowing administrators and auditors to trace exactly who accessed what information and when.

Acceptance Criteria
Automated Lock Event Recording
Given a system-initiated lock on a patient record When the lock occurs Then the event is recorded with a timestamp, event type 'auto-lock', user ID 'SYSTEM', and device ID in the audit ledger.
Manual Override Event Logging
Given a clinician manually overrides a record access lock When the override is executed Then the event is logged with timestamp, overriding user’s ID, device ID, override reason, and a unique event ID.
Real-Time Messaging-triggered Entries
Given an access event triggers a messaging alert When the event occurs Then the system generates a ledger entry within 2 seconds and sends a message update that references the same event ID.
Immutable Ledger Storage Verification
Given any logged access event When comparing stored entries Then the system prevents modifications or deletions and generates a tamper-proof hash chain entry.
User and Device Identifier Tagging
Given access to patient data When any event is logged Then each entry includes valid user ID and device identifier matching the authenticated session.
Tamper-Proof Log Storage
"As a compliance manager, I want the audit trail to be tamper-evident so that we can prove to regulators the integrity and immutability of our security logs."
Description

Implement an append-only storage mechanism for audit logs using cryptographic hashing or blockchain-inspired techniques to prevent modification or deletion of existing entries. Each new log entry should reference the hash of the previous entry, creating a chain of trust. Storage should be encrypted at rest and authenticated on retrieval, ensuring logs cannot be altered without detection.

Acceptance Criteria
Real-Time Log Entry Creation
Given a system event occurs, when the event is logged, then the new log entry is appended to storage with a cryptographic hash referencing the previous entry and a timestamp.
Log Chain Integrity Verification
When logs are retrieved or audited, the system recalculates each entry’s hash and verifies it matches the stored link chain; any discrepancy triggers an integrity alert.
Encrypted At-Rest Storage Validation
All audit logs are stored on disk encrypted with AES-256; direct file inspection shows only ciphertext and decryption only succeeds with valid encryption keys.
Authenticated Log Retrieval
Given an authenticated user requests log data, when retrieval occurs, then the system verifies each entry’s hash chain and returns logs only if integrity checks pass.
Unauthorized Modification Prevention
Any attempt to modify or delete an existing log entry results in an error response, and the attempt itself is recorded as a new tamper-event log entry.
Detailed Override Recording
"As a shift supervisor, I want every override to be logged with a justification so that I can review and validate exceptions to standard access policies."
Description

Record detailed information for every override event, including the rationale provided, authorizing supervisor’s identifier, end user’s identifier, timestamp, and any associated message context. The system must prompt authorized users to input an override justification and capture this alongside other override metadata in the ledger.

Acceptance Criteria
Override Justification Prompt
Given an authorized user initiates an override, when the override dialog appears, then the system must prompt for a justification input and prevent proceeding until a non-empty justification of at least 10 characters is entered.
Supervisor Identifier Logging
Given a supervisor approves an override, when the override is submitted, then the system must record the supervisors unique user ID in the audit trail entry.
End User Identifier Capture
Given an override event occurs, when the event is logged, then the system must capture and store the initiating end users unique user ID alongside the override record.
Override Event Timestamp Recording
Given any override action is completed, when the record is generated, then the system must attach the server-generated timestamp (in UTC) to the override entry, accurate to the second.
Associated Message Context Logging
Given an override is performed in response to a specific message, when the override record is created, then the system must include the message identifier and content snapshot in the audit log entry.
Configurable Retention Policies
"As an IT administrator, I want to configure how long different types of logs are retained so that we comply with varying legal and policy requirements without manual intervention."
Description

Provide administrators with the ability to define retention periods for audit logs based on regulatory requirements or organizational policies. The system should support automatic archiving or secure deletion of logs once their retention period expires. Retention settings must be applied per log category (e.g., access events, overrides) and enforceable across distributed storage nodes.

Acceptance Criteria
Admin Configures Retention Policy by Category
Given an administrator navigates to the retention settings page When the administrator defines a retention period for the "access events" category and saves the configuration Then the system persists the setting and displays the new retention period next to the "access events" category
System Automatically Archives Expired Logs
Given audit logs reach the end of their configured retention period When the retention job runs at the scheduled interval Then logs older than the retention period are moved to an archive storage location and marked as archived
System Securely Deletes Logs Past Retention Period
Given archived logs exceed the maximum archive duration defined by policy When the deletion process is triggered Then the system permanently removes the logs from all storage nodes and verifies deletion integrity
Retention Policy Enforced Across All Storage Nodes
Given multiple distributed storage nodes host audit logs When an administrator updates the retention settings for any log category Then all nodes apply the updated retention policy within five minutes and report their status to the central management console
Retention Actions are Logged for Compliance
Given the system performs an archive or delete action due to retention policy When the action completes Then an immutable audit entry is generated with timestamp, action type, category, and affected log identifiers
Automated Audit Report Generation
"As an auditor, I want to generate comprehensive audit reports so that I can efficiently review security compliance and share findings with stakeholders."
Description

Enable scheduled and on-demand generation of audit reports summarizing access events, overrides, and compliance metrics.

Acceptance Criteria
Nightly Scheduled Report Generation
Given a daily schedule is configured for 02:00 AM, when the scheduler triggers, then the system generates a PDF and JSON/CSV report summarizing the previous day’s access events, overrides, and compliance metrics and stores them in the audit repository.
On-Demand Report Generation by Authorized User
Given an authorized user accesses the report interface and requests an on-demand report, when they submit the request, then the system generates the report within 60 seconds and makes PDF and JSON/CSV downloads available.
Filtered Audit Report Generation
Given a user applies date range, user role, event type, and patient context filters, when they run the report, then the generated output includes only events matching all selected filters.
Multi-Format Report Export Capability
Given a report has been generated, when the user selects export options, then the system provides valid PDF, JSON, and CSV files that meet schema definitions and maintain data integrity.
Email Delivery of Generated Reports
Given email delivery is configured, when a report (scheduled or on-demand) completes, then the system emails the PDF version to the designated recipients within 5 minutes.
Secure Log Export and Integration
"As a systems integrator, I want to export audit logs to our SIEM so that we can incorporate PulseLink events into our centralized security monitoring and incident response workflows."
Description

Develop APIs and export tools allowing secure transmission of audit logs to external systems such as SIEMs, data lakes, or third-party compliance platforms. Exports must support encryption in transit, authentication via API keys or OAuth, and filtering by date, user, or event type to ensure only relevant data is shared.

Acceptance Criteria
API Export with Date and User Filters
Given valid API credentials, when a request to export logs is made with a specified date range and user filter, then the response returns only log entries matching the date range and user in JSON format with HTTP 200 status.
OAuth-Authenticated Scheduled Export
Given a valid OAuth token, when the scheduled export job runs, then logs are securely transmitted over HTTPS using TLS 1.2+ to the data lake and the receiving system acknowledges receipt with a 2xx status.
API Key Authentication and Event Type Filtering
Given a valid API key associated with specific event types, when the export request specifies an event type filter, then only logs of those event types are returned and all others are excluded.
Encrypted Transmission to Compliance Platform
Given an export to a third-party compliance platform, when log data is transmitted, then the data must be encrypted in transit using TLS AES-256 and network capture analysis shows no plaintext data.
Error Handling for Invalid Export Requests
Given an export request with invalid parameters or authentication, when the system processes the request, then it returns an appropriate HTTP 4xx or 401 error with a descriptive message and no data is exported.

Severity Spectrum

Displays a dynamic color-coded gradient alongside each message, instantly reflecting patient vitals severity. Clinicians can visually scan conversations to identify high-risk patients at a glance, speeding up triage and reducing oversight in busy environments.

Requirements

Dynamic Severity Gradient
"As a clinician, I want messages to display a dynamic color gradient reflecting patient vitals severity so that I can quickly identify high-risk patients without reading detailed metrics."
Description

Compute and display a dynamic, color-coded gradient that maps patient vitals severity on a spectrum from green (stable) to red (critical). The gradient must update in real time as new vital sign data arrives, integrate seamlessly with the messaging interface, and adhere to brand color guidelines. Its purpose is to enable clinicians to instantly assess patient risk levels at a glance, reducing triage time and preventing oversight in the fast-paced hospital environment.

Acceptance Criteria
Real-Time Gradient Update During Live Chat
Given a patient’s vital signs update arrives, when the data is processed by the system, then the color-coded gradient alongside the message updates within 1 second without any visual lag or delay.
Gradient Alignment with Brand Colors
Given the brand color guidelines specify hex values for stable (green) and critical (red), when rendering the gradient, then the system uses the exact provided hex codes and produces a smooth, continuous spectrum between them.
Seamless Integration in Messaging UI
Given the messaging interface on desktop and mobile, when displaying messages with the severity gradient, then the gradient appears adjacent to each message bubble, maintains correct alignment, and does not overlap or shift message content across all supported resolutions.
Accurate Severity Mapping from Incoming Vitals
Given incoming vital sign data mapped to a severity score from 0 to 100, when the score updates, then the gradient position corresponds linearly to the score and correctly reflects threshold color transitions at predefined clinical limits.
Performance Under High Message Volume
Given a high-throughput scenario of 100 messages per minute with continuous vital updates, when the system processes messages, then the gradient updates maintain messaging performance with no more than 10% CPU utilization overhead.
Real-time Vital Data Integration
"As a care coordinator, I want the severity spectrum to reflect real-time patient vitals so that I can rely on up-to-the-minute information during urgent decision-making."
Description

Fetch, process, and normalize patient vital sign data in real time from the hospital’s EHR and IoT monitoring systems via secure APIs. The integration must handle streaming updates, data caching for performance, and fallback mechanisms for latency or missing data. This ensures the severity spectrum reflects the latest patient status without delay, maintaining clinical accuracy and reliability.

Acceptance Criteria
Initial Data Retrieval on Shift Start
Given a clinician begins their shift and opens PulseLink, When the app initializes, Then it fetches and displays the latest vital sign data for all assigned patients within 5 seconds.
Continuous Streaming Update
Given ongoing patient monitoring, When new vital data arrives via the EHR or IoT stream, Then the severity spectrum color gradient updates within 2 seconds without any dropped or delayed messages.
Data Caching Under Network Load
Given a peak data load exceeding 500 updates per minute, When the system processes incoming streams, Then data is cached in-memory and the UI refresh rate remains ≤1 second with no performance degradation.
Fallback to Last Known Data on Latency
Given network latency over 500 ms or API timeout, When fetching real-time vitals fails, Then the app displays the last known valid data with a visible warning icon and retries the connection every 30 seconds.
Handling Missing or Invalid Data Points
Given incoming data with missing or invalid fields, When ingestion occurs, Then the system logs the anomaly, substitutes null values safely, and preserves the previous valid data point in the severity spectrum display.
Message UI Overlay Integration
"As a clinician, I want the severity gradient to be overlaid next to each message in the chat interface so that I can easily scan for critical alerts while reviewing patient communication."
Description

Integrate an overlay widget within the messaging interface that displays the severity gradient alongside each message. The widget must adapt its size, position, and behavior for various screen sizes and message lengths, ensuring it remains unobtrusive yet visible. It should integrate with existing message components and maintain performance under high message volumes.

Acceptance Criteria
Small Mobile Screen Display
Given clinician uses PulseLink on a mobile device with screen width <= 360px, When a message appears, Then the severity gradient overlay resizes proportionally to the message bubble height and does not overlap the message text.
Desktop View with Varying Message Lengths
Given PulseLink is viewed on a desktop browser with window width >= 1200px and a message length > 200 characters, When the message renders, Then the severity gradient overlay adjusts its height to match the message container without causing horizontal scroll or layout shifts.
High Throughput Message Load
Given the system processes 500 messages within one minute, When messages and overlays render, Then each overlay appears within 100ms of its message and no rendering errors or dropped overlays occur.
Integration with Existing Components
Given existing message components (avatar, timestamp, sender info), When the severity overlay is integrated, Then all components remain aligned, clickable, and unobstructed, and the overlay does not cover any interactive element.
Scroll Behavior with Severity Overlay
Given a long message list, When the user scrolls quickly, Then each severity gradient overlay remains fixed to its corresponding message without flickering, detaching, or lag.
Customizable Severity Thresholds
"As a hospital admin, I want to customize severity thresholds so that the color spectrum aligns with our institution’s clinical guidelines."
Description

Provide an administrative configuration panel allowing authorized users to define and adjust threshold values for each severity level (e.g., green, yellow, orange, red). Changes should apply in real time and be logged for audit purposes. This capability ensures the color spectrum aligns with evolving medical protocols and institutional policies.

Acceptance Criteria
Admin Adjusts Severity Thresholds
Given an authorized admin is on the configuration panel, When they input new numerical threshold values for each severity level and click 'Save', Then the system updates the thresholds in the application in real time without requiring a system restart
Real-Time Threshold Application
Given updated thresholds have been saved, When a new patient vital measurement is received, Then the message severity color reflects the new threshold immediately
Threshold Change Audit Logging
Given an admin saves threshold changes, When the change is committed, Then the system logs the user ID, timestamp, previous and new values in the audit log
Access Control for Threshold Configuration
Given a user without admin privileges attempts to access the configuration panel, Then the system denies access and displays an 'Insufficient Permissions' message
Validation of Threshold Input Values
Given an admin enters threshold values outside allowed ranges, Then the system displays inline validation errors and prevents saving
Accessibility and Compliance
"As a user with color vision deficiency, I want alternative indicators for severity so that I can accurately interpret patient risk levels in the messaging interface."
Description

Ensure the severity spectrum visualization meets WCAG 2.1 AA color contrast requirements and ADA guidelines for color-blind users. Include pattern overlays or icons as alternatives to color alone, and provide tooltips with textual severity indicators on hover. This guarantees that all clinicians, regardless of visual ability, can accurately interpret patient risk levels.

Acceptance Criteria

Each severity level gradient color pair maintains a minimum contrast ratio of 4.5:1 according to WCAG 2.1 AA when tested with a contrast analyzer tool.
Color-Blind Mode Visualization
Under deuteranopia, protanopia, and tritanopia simulations, each severity level remains visually distinguishable, as verified by automated UI tests.
Pattern Overlay Accessibility
Each severity indicator includes a unique, high-contrast pattern overlay or icon legible at 16px size that conveys severity independently of color.
Tooltip Information Accuracy
Hovering over a severity indicator triggers a tooltip within 200ms displaying the correct textual severity label (e.g., “Low,” “Moderate,” “High,” “Critical”).
Keyboard Navigation and Focus Indicators
Users can navigate to severity indicators via the Tab key and see a visible 2px focus ring with at least 3:1 contrast around the focused element.

Urgent Beacon

Sends prioritized push notifications for messages flagged as critical, pulsing a distinct alert tone and vibration pattern. Ensures that life-threatening situations cut through ambient noise, giving clinicians immediate visibility even when the app is running in the background.

Requirements

Critical Message Flagging
"As a clinician, I want to mark a message as critical so that urgent notifications are triggered immediately for my team."
Description

Implement a user interface control that allows clinicians to flag messages as critical. When a message is flagged, the backend must mark it as urgent and route it through the prioritized alert pipeline. This feature ensures that life-threatening or time-sensitive communications are distinctly identified and handled with the highest priority, reducing response times and improving patient outcomes.

Acceptance Criteria
Clinician Flags a Deteriorating Patient Message as Critical
Given a clinician selects the critical flag on a patient message, When the clinician sends the message, Then the backend marks the message as urgent and routes it through the prioritized alert pipeline within 2 seconds.
Standard Message Without Critical Flag
Given a clinician sends a message without selecting the critical flag, When the message is delivered, Then no urgent beacon is triggered and the message follows standard delivery protocols.
Background App Receives Critical Alert
Given the app is running in the background on a clinician’s device, When a message is flagged as critical, Then the device receives a high-priority push notification with the distinct critical tone and vibration pattern within 5 seconds.
Admin Audits Critical Flags
Given an administrator accesses the audit logs, When reviewing flagged messages, Then all messages marked as critical appear with their timestamps, clinician ID, and patient ID in chronological order.
Multiple Critical Flags Processed in Queue
Given multiple messages are flagged as critical simultaneously, When the system processes the queue, Then each critical message is delivered in the order received with no loss or duplication, and each triggers the urgent beacon.
Distinct Alert Tone Integration
"As a clinician, I want urgent messages to play a distinct alert tone so that I can immediately identify critical notifications."
Description

Integrate a unique alert tone exclusively for urgent beacon notifications. Package the audio asset within the app bundle, configure the mobile OS notification API to play this tone for high-priority messages, and provide a fallback option if the user’s device is in silent mode. This ensures critical alerts are audibly distinct, cutting through ambient noise and immediately notifying clinicians.

Acceptance Criteria
Distinct Tone Playback on High-Priority Message Reception
Given an urgent beacon message is received When the app is in foreground Then the unique alert tone plays with the specified vibration pattern within 500ms
Background Notification Trigger
Given the app is running in the background When a critical message arrives Then the OS notification API issues the distinct alert tone and vibration even if the app is not active
Silent Mode Fallback Activation
Given the device is in silent or Do Not Disturb mode When an urgent beacon message is received Then the app overrides silent mode to play the distinct tone at user-defined volume
Audio Asset Packaging Verification
Given the app bundle is built When the installation package is inspected Then the audio file for the distinct alert tone is present in the designated resource folder
User Preference Respect Handling
Given a user has disabled vibration in app settings When an urgent beacon notification arrives Then only the distinct alert tone is played without vibration
Custom Vibration Pattern
"As a clinician, I want urgent messages to trigger a unique vibration pattern so that I can detect critical alerts by touch."
Description

Define and deploy a dedicated vibration pattern for urgent beacon notifications across all supported devices. Specify a sequence of vibration pulses that differentiates urgent alerts from standard notifications. Test implementation on both iOS and Android platforms to ensure consistent tactile feedback, enabling clinicians to detect critical messages through touch, even in noisy or high-activity environments.

Acceptance Criteria
Locked Phone Urgent Alert Vibration
Given a clinician's device is locked and in silent mode, When an urgent message is received, Then the device vibrates following the defined urgent beacon pattern (e.g., 300ms on, 100ms off, 300ms on, 100ms off) exactly, on both iOS and Android.
Rapid Succession Alerts
Given multiple urgent messages arrive within 2 seconds, When each urgent notification is triggered, Then the full vibration pattern plays for each without overlap or truncation on both iOS and Android.
Muted Standard Notifications Override
Given standard notifications are muted by the user, When an urgent beacon is triggered, Then the device still executes the urgent vibration pattern.
Cross-Platform Vibration Fidelity
Given a test suite measuring vibration timing, When the urgent pattern is executed on iOS and Android devices, Then the pulse durations and intervals match within a tolerance of ±10 milliseconds for each pulse and pause.
Backgrounded App Vibration Activation
Given the PulseLink app is running in the background or is closed, When an urgent beacon notification arrives, Then the device vibrates with the defined pattern without requiring the app to be in the foreground.
Background Delivery Guarantee
"As a clinician, I want to receive urgent notifications even when the app is not active so that I don't miss critical patient updates."
Description

Ensure urgent beacon notifications are reliably delivered when the app is running in the background or terminated. Leverage high-priority channels in APNs for iOS and FCM for Android, implement fallback local notification scheduling, and monitor delivery success rates. This requirement guarantees no critical alert is missed, regardless of the app’s state, maintaining team situational awareness.

Acceptance Criteria
High-Priority APNs Delivery
Given an iOS device with the app in the background or terminated, when an urgent beacon notification is sent via APNs with the high-priority flag, then the notification is displayed on the device within 5 seconds of sending.
High-Priority FCM Delivery
Given an Android device with the app in the background or terminated, when an urgent beacon notification is sent via FCM with the high-priority flag, then the notification is displayed on the device within 5 seconds of sending.
Local Notification Fallback
Given the app does not receive a push notification within 10 seconds due to network or service interruption, when the fallback scheduler triggers, then a local urgent beacon notification is displayed to the clinician.
Delivery Success Monitoring
System records delivery status and timestamps for each urgent beacon notification, and the aggregate delivery success rate over a rolling 24-hour window is ≥ 99%.
Offline to Online Transition
Given the device is offline when an urgent beacon notification is sent, when the device regains network connectivity within 30 seconds, then any pending urgent beacon notifications are delivered immediately with the distinct alert tone and vibration pattern.
Delivery Acknowledgment and Logging
"As a care coordinator, I want to track when urgent messages are delivered and acknowledged so that I can ensure timely responses."
Description

Implement an acknowledgment mechanism that logs when urgent beacon notifications are delivered to the device and when they are viewed or dismissed by the user. Sync these events with the server to create an audit trail for compliance and performance monitoring. This feature provides visibility into delivery and response times, enabling care coordinators to ensure timely follow-up.

Acceptance Criteria
Notification Delivery Logged
Upon receipt of an urgent beacon notification, the app logs the delivery timestamp, notification ID, and device ID locally, and marks the entry as pending server sync.
Notification Viewed Acknowledgment
When the user opens the urgent beacon notification, the app captures the view event with timestamp and user ID, and syncs the event to the server within 5 seconds.
Notification Dismissal Logging
When the user dismisses the urgent beacon notification without viewing, the app records the dismissal event with timestamp and user ID, and flags it for server synchronization.
Server Sync for Delivery Events
When the device regains network connectivity, the app automatically sends all pending delivery, view, and dismissal logs to the server and confirms receipt by clearing pending flags.
Audit Trail Data Integrity
At any time, the server's audit trail for a specific notification must include exactly one delivery event and one view or dismissal event with accurate timestamps matching the client logs, and discrepancies trigger an alert.

Adaptive Thresholds

Leverages AI to learn individual patient baselines and automatically adjusts alert thresholds as conditions evolve. By reducing false positives and focusing on true deviations, clinicians receive more meaningful alerts tailored to each patient’s unique profile.

Requirements

Baseline Learning Engine
"As a care coordinator, I want the system to learn each patient's normal vitals over time so that alerts reflect genuine deviations from their personal health patterns."
Description

Implement an AI-driven engine that continuously analyzes incoming patient vital signs and historical data to establish and update individualized baseline metrics. The system must securely store and process data within HIPAA-compliant infrastructure, support incremental learning as new data arrives, and provide an API for downstream features to query current patient baselines.

Acceptance Criteria
Admission Baseline Initialization
Given a newly admitted patient with at least 24 hours of recorded vital signs, When the Baseline Learning Engine processes this data, Then it establishes initial baseline metrics (mean and standard deviation) for heart rate, blood pressure, respiration rate, and oxygen saturation within 5 minutes of data availability.
Continuous Baseline Update
Given an existing patient baseline, When new vital sign data arrives hourly, Then the engine incrementally updates the baseline metrics within 5 minutes of data receipt without full dataset reprocessing.
API Baseline Retrieval
Given a clinician requests a patient’s current baseline via the API, When the request includes a valid patient ID, Then the API returns the latest baseline metrics in JSON format (including patient ID, timestamp, and metric values) within 300ms and HTTP status 200.
HIPAA-Compliant Data Storage
Given patient data is processed by the engine, When data is written to storage, Then all data must be encrypted at rest with AES-256, access must be logged, and only authorized service accounts can read or write the data.
Handling Missing Data
Given intermittent gaps in incoming vital sign data up to 2 hours, When data is missing, Then the engine uses interpolation or retains the previous baseline without biasing updates, logs a warning, and postpones baseline updates until at least 3 valid new data points are available.
Scale Performance Under High Load
Given the engine processes up to 1000 concurrent patient data streams, When all streams send data simultaneously, Then the engine updates each patient baseline within 10 seconds per update and maintains error rates below 0.1%.
Dynamic Threshold Adjustment
"As a clinician, I want alert thresholds to adapt automatically as a patient’s condition changes so that I receive meaningful notifications instead of constant false alarms."
Description

Enable the system to automatically adjust alert thresholds in real time based on learned patient baselines and evolving trends. This feature should leverage the Baseline Learning Engine’s outputs to recalibrate alarm boundaries, reduce noise from false positives, and trigger alerts only when clinically significant deviations occur.

Acceptance Criteria
Real-time Threshold Recalibration
Given continuous patient vital sign data streaming, when the Baseline Learning Engine updates a patient’s baseline trend, then the system must apply recalibrated thresholds within 2 seconds and suppress any alerts for values that fall within the new threshold range.
Clinician Notification of Threshold Changes
Given a threshold adjustment event, when the system recalibrates a patient’s alarm boundaries, then an alert detailing the old and new threshold values must be sent to the assigned clinician within 5 seconds and the notification must be logged.
Threshold Stability During High Variability
Given a period of rapid vital sign fluctuations, when the engine adjusts thresholds more than three times within 10 minutes, then the system must verify each new threshold is within clinically safe bounds and prevent adjustments that would exceed predefined maximum deviation limits.
Audit Trail for Threshold Adjustments
Given any automatic threshold adjustment, when the event occurs, then the system must create an audit record including timestamp, patient ID, previous threshold, new threshold, and adjustment reason, and make it retrievable via the audit API.
Fail-safe Reversion on AI Anomaly
Given an anomaly or failure in the Baseline Learning Engine during threshold recalibration, when such an error is detected, then the system must revert to the last known safe default thresholds within 3 seconds and log the failure with error details.
Threshold Override Interface
"As a nurse, I want to manually adjust alert thresholds when necessary so that I can ensure urgent alerts align with the immediate clinical context."
Description

Provide an intuitive user interface allowing clinicians to manually review and override AI-generated thresholds. The interface must display current baseline values, suggested thresholds, and historical alarm data, and allow authorized users to set temporary or permanent custom limits that override automated settings.

Acceptance Criteria
Clinician Reviews AI-Suggested Threshold
Given the AI-generated threshold is displayed for a patient When an authorized clinician selects “Override” and inputs new temporary limits and clicks “Apply” Then the system updates the patient’s threshold to the new values for the remainder of the shift And the override action is recorded in the historical log with timestamp and user ID
Unauthorized User Attempts Override
Given a user without override permissions is logged in When the user attempts to modify threshold values Then the override controls remain disabled And an “Insufficient permissions” message is displayed And no changes are saved or recorded
Permanent Override Persists Across Shifts
Given an authorized clinician sets a permanent override in the interface When the clinician confirms and saves the setting Then the new threshold values apply across all subsequent shifts until explicitly reverted And the historical log marks this entry as “Permanent Override” with user details
Historical Data Display Accuracy
Given the clinician opens the threshold override interface for a patient When viewing the Historical Alarms section Then the interface lists all past alarm events in descending chronological order And each entry displays date-time, threshold values, alarm condition, and responsible user
Temporary Override Expires at Shift End
Given a clinician sets a temporary override valid for the current shift When the clinician’s shift ends Then the system automatically resets the threshold to the AI-suggested value And the clinician receives a notification that the temporary override has expired
Alert Accuracy Feedback Loop
"As a physician, I want the system to learn from my feedback on alerts so that it continually improves accuracy and reduces irrelevant notifications."
Description

Develop a feedback mechanism that captures clinician responses to alerts—acknowledged, dismissed, or flagged—and feeds this information back into the AI model to refine future threshold adjustments. Data collected must include timestamp, user action, and contextual notes to improve model training and alert relevance.

Acceptance Criteria
Clinician Acknowledges Alert with Contextual Note
Given an active patient alert is generated, When a clinician selects 'Acknowledge' and enters a contextual note, Then the system records the action with timestamp, userID, and note, and feedback entry is queued for AI model training.
Clinician Dismisses False Positive Alert
Given an alert is determined false positive, When the clinician selects 'Dismiss', Then the system logs the dismissal with timestamp and userID, updates the feedback loop, and ensures no further similar alerts for at least 2 hours unless threshold changes.
Clinician Flags Missed Critical Event
Given a patient condition meets risk criteria but no alert was generated, When the clinician flags the missed alert and provides contextual notes, Then the system logs the flag with timestamp, userID, context, and triggers model retraining data ingestion pipeline.
Automated Feedback Integration in AI Model
Given collected feedback entries, When the AI model conducts its scheduled retraining, Then feedback data is included and model logs indicate incorporation of recent feedback records.
Feedback Data Integrity and Timestamp Accuracy
Given any feedback action is logged, Then every entry includes a valid ISO8601 timestamp, authenticated userID, and context, with no missing or null fields.
Patient Profile Synchronization
"As a clinician, I want consistent threshold settings on my mobile app and desktop dashboard so that I receive uniform alerts regardless of which device I use."
Description

Ensure that patient-specific threshold configurations and baseline data are synchronized across all devices and clinician accounts in real time. This requires a robust sync service that handles live updates, conflict resolution, and ensures that only currently active team members receive up-to-date alert settings.

Acceptance Criteria
Real-time Threshold Update Across Devices
Given a clinician updates a patient’s alert threshold on Device A, when another clinician views that patient’s profile on Device B within 5 seconds, then the updated threshold configuration is displayed accurately on Device B.
Conflict Resolution for Concurrent Updates
Given two clinicians update the same patient’s baseline data simultaneously on different devices, when the sync service detects the conflict, then it applies the update with the latest timestamp and logs both changes for audit.
Active Team Member Access Control
Given a clinician’s shift has ended, when the sync service propagates patient thresholds, then the clinician’s account no longer receives real-time updates and cannot access updated settings.
Offline Mode Synchronization Recovery
Given a clinician loses network connectivity while updating thresholds, when the device reconnects to the network, then all pending changes are synchronized without data loss or duplication.
Selective Data Synchronization for Patient Privacy
Given a patient’s privacy settings restrict certain baseline details, when synchronizing thresholds across devices, then only non-restricted data fields are propagated to authorized clinician accounts.

"As a care coordinator, I want to customize threshold settings for each patient group so that alerts are tailored to specific clinical protocols and reduce false positives."
Description

Provide an intuitive user interface within PulseLink’s settings that allows clinical administrators to define and adjust threshold parameters for different vital signs and lab values. Users should be able to set both absolute and relative threshold values, configure trend durations, and receive previews of how changes impact trend detection. Configurations must be saved per patient population and role-based permissions applied to prevent unauthorized changes.

Acceptance Criteria
Absolute Vital Threshold Configuration
Given a clinical administrator accesses threshold settings, when they set an absolute threshold for heart rate to 100 bpm, then the system saves the threshold and reflects it in the TrendSpot previews.
Relative Threshold Configuration
Given a clinical administrator selects a relative threshold, when they set a 20% increase for blood pressure over a 2-hour period, then TrendSpot updates the previews accordingly and flags values exceeding the threshold.
Trend Duration Adjustment Preview
Given a clinical administrator configures the trend duration to 4 hours, when they apply changes, then the system displays a preview chart showing data points and trend detection over the new duration.
Patient Population-Based Saving
Given an administrator configures thresholds for the Cardiac Unit population, when they save settings, then the thresholds are stored under 'Cardiac Unit' and are isolated from other patient populations.
Role-Based Access Control Enforcement
Given a user with a Nurse role attempts to change thresholds, when they try to save, then the system denies access and displays an 'Insufficient Permissions' error.
Contextual Alert Notifications
"As a shift nurse, I want to receive concise, patient-specific alerts when critical trends arise so that I can intervene promptly and coordinate care."

Given a generated trend notification When viewed in PulseLink Then the message includes the patient’s full name and medical record number, the specific parameter name, magnitude of change, start and end timestamps, and aligns with UI content standards
Unacknowledged Alert Escalation
Given no acknowledgment from primary recipients within 5 minutes of dispatch When the escalation timer elapses Then the system automatically forwards the notification to the on-call supervisor and flags the original notification as escalated
Audit Logging of Notifications
Given any notification or escalation event When the event occurs Then the system creates a secure audit log entry capturing patient ID, trend details, recipient list, timestamps of dispatch and acknowledgment, and escalation status
Trend Annotation in Patient Digest
"As a returning clinician, I want to see flagged trends highlighted within the patient digest so that I can understand patient status at a glance."
Description

Implement an annotation layer within the patient summary digest that visually highlights detected trends directly in the vitals and lab sections. Annotations should include color-coded indicators (e.g., red for worsening, green for improving), tooltip explanations, and the ability to expand into a mini-graph of the trend over time. The annotations must maintain HIPAA compliance and integrate seamlessly with existing digest layouts.

Acceptance Criteria
Worsening Vital Trend Indicator
Given a patient’s vital sign shows a worsening trend, when viewing the digest, then a red downward or upward arrow icon appears next to the vital value within 500ms of loading.
Improving Lab Value Annotation
Given a lab value improves over three consecutive readings, when viewing the digest, then a green upward arrow icon is displayed beside the lab result and persists during the session.
Trend Tooltip Explanation
Given an annotation icon is present, when the user hovers over or taps the icon, then a tooltip appears within 200ms showing the trend type, direction, percentage change, and timestamp of the first and last readings.
Mini-Graph Expansion Interaction
Given an annotation icon, when the user clicks or taps the icon, then an expandable mini-graph overlay appears plotting at least six time-stamped data points over the past 24 hours, and can be closed by clicking a close icon.
HIPAA-Compliant Annotation Data Handling
Given annotations are rendered, when data is transmitted and stored, then all annotation payloads are encrypted in transit (TLS 1.2+) and at rest, and no additional PHI fields are exposed beyond existing digest content.
Audit and Reporting Trail
"As a compliance officer, I want to access detailed logs of trend detection and alert events so that I can verify system integrity and regulatory compliance."
