📋 Longitudinal Care Plan Implementation Plan

🎯 ObjectiveCopy Anchor Link

Transform the Care Plan from an encounter-focused system to a comprehensive longitudinal patient health record that provides a complete view of patient's medical journey over time.

📊 Todo List - 20 TasksCopy Anchor Link

Phase 1: Core Infrastructure (Tasks 1-8)Copy Anchor Link

1. ✅ Create LongitudinalHealthRecord.tsx page component at /cms/src/pages/care-plan/

3. ✅ Create PatientSummaryDashboard component showing key metrics and recent activity
4. ✅ Build VitalsTrendChart component with Recharts for BP, weight, heart rate trends
5. ✅ Implement ProblemListManager component for persistent problem tracking
6. ✅ Create MedicationTimeline component showing medication history
7. ✅ Build EncounterHistory component listing all patient encounters
8. ✅ Create data aggregation service to combine data from multiple encounters

Phase 2: Navigation & Integration (Tasks 9-11)Copy Anchor Link

9. ✅ Update Patient Detail 'View Care Plan' button to navigate to longitudinal view
10. ✅ Add navigation from Care Plan back to Patient Detail
11. ✅ Create useLongitudinalData hook for fetching aggregated patient data
