• Route critical health alerts through multiple channels (SMS, app notification, clinical dashboard) based on severity.
• Integrate real-time analytics with clinical triage workflows to prioritize patient follow-up.
• Log and analyze alert response times to evaluate system effectiveness and refine escalation protocols.
• Apply windowing techniques to smooth noisy sensor data before triggering automated alerts.

Module 6: Patient Engagement and Behavioral Analytics

• Segment users based on engagement patterns (e.g., active trackers, intermittent users) to tailor intervention strategies.
• Analyze app interaction logs to identify UX friction points that reduce long-term adherence to health monitoring.
• Design nudging algorithms that deliver personalized wellness prompts based on time-of-day, activity level, and historical compliance.
• Correlate self-reported mood or symptom data with physiological trends to support mental wellness insights.
• Implement A/B testing frameworks to evaluate the impact of interface changes on user data entry completeness.
• Develop feedback loops that allow users to correct or contextualize anomalous data points flagged by AI.
• Measure intervention efficacy using quasi-experimental designs when randomized trials are impractical.
• Protect user privacy when analyzing behavioral patterns by minimizing data collection to essential features only.

Module 7: Integration with Clinical Workflows
