Duty Hour

Duty Hour App is a comprehensive, mobile-first platform designed to streamline duty-hour tracking, ensure ACGME compliance, and support resident well-being—all with minimal reliance on constant Internet connectivity. It combines geofencing, on-device intelligence, AI-driven insights and seamless integrations into a single, extensible solution for residents, program directors and GME administrators.

1. Overview
   • Purpose: Automate shift-logging and compliance reporting while proactively identifying duty-hour violations, burnout risk and fatigue.
   • Target users: Residents/fellows (clock-in/out, breaks, wellness checks), program directors (real-time dashboards, reports), GME offices (audit trails, accreditation exports).

2. Core Features
   • Geofence + Wi-Fi/IP “Handshake”: Auto-enter on-site mode when a user crosses the hospital perimeter and joins the local network.
   • Offline-First Logging: All clock-ins, breaks and wellness entries write to a local encrypted SQLite store; syncs bi-directionally when network returns.
   • Real-Time Rule Engine: On-device enforcement of duty-hour caps, break requirements and alerts within 100 ms, even offline.
   • Seamless Sync & Conflict Resolution: Delta-based uploads over TLS, timestamped entries and merge logic to handle edits across devices.

3. AI & Analytics
   • Predictive Violation Risk: ML models forecast who’s most likely to exceed weekly or per-shift limits; early warning nudges residents to swap or rest.
   • Auto-Narrative Reporting: LLM-powered summaries turn raw log tables into plain-English monthly or quarterly reports for PDs and DIOs.
   • Smart Scheduling Suggestions: Constraint-solver recommendations balance institutional needs against individual fatigue profiles.

4. Biometric & Fatigue Mitigation
   • Sleep & Recovery Dashboard: Integrates HealthKit, Google Fit or third-party wearables (Oura, Fitbit) to chart sleep duration, efficiency, HRV and resting heart rate.
   • Fatigue Risk Score: Combines biometric data and upcoming shift load into a 0–100 risk index, color-coded with personalized mitigation tips (naps, schedule swaps).
   • Proactive Alerts: Push notifications when risk crosses thresholds, with links to in-app fatigue-hygiene library.

5. Technical Architecture
   • Mobile Clients: Native iOS (Swift/HealthKit) apps with background geofence and BLE scanning.
   • Edge vs. Cloud Inference: Lightweight Core ML/TensorFlow Lite models on-device; heavier training and LLM calls in Kubernetes or serverless APIs.
   • Data Pipeline: Event-stream ingestion (Kafka/Kinesis) of logs, biometrics and app interactions feeding both analytics warehouse (Snowflake/BigQuery) and ML training clusters.
   • Extensibility: Open REST/GraphQL APIs + webhooks for EHR, scheduling systems or custom hospital-policy plugins.

6. Key Benefits
   • Reliability: Residents never miss a clock-in/out even if hospital Wi-Fi or the public Internet goes down.
   • Speed & Trust: Instant alerts and rule checks build confidence in the system’s accuracy.
   • Compliance Made Easy: Automated ACGME exports, direct NLRB-union reporting capabilities and audit trails reduce administrative overhead.
   • Well-Being Focus: Integrated fatigue-mitigation engine and AI insights foster healthier scheduling and targeted interventions.

7. Integrations & Future Roadmap
   • Third-Party Wearables: Expand to Garmin, Samsung Health, WHOOP.
   • Enterprise Tools: SCIM/SAML SSO, MDM enrollment for managed devices.
   • Marketplace Plugins: Peer-swap boards, on-call escalation, local-policy rule engines.

With Duty Hour App, institutions get a single, end-to-end solution that not only enforces duty-hour compliance but also champions resident wellness, leverages AI intelligence and scales across any device or form factor.
