# Feature Specification: Care API - Sistema de gestão de cuidados de saúde
**Feature Branch**: `001-care-api-sistema`
**Created**: 2025-09-12
**Status**: Draft
**Input**: User description: "Care API - Sistema de gestão de cuidados de saúde"
## Execution Flow (main)
```
1. Parse user description from Input
→ If empty: ERROR "No feature description provided"
2. Extract key concepts from description
→ Identify: actors, actions, data, constraints
3. For each unclear aspect:
→ Mark with [NEEDS CLARIFICATION: specific question]
4. Fill User Scenarios & Testing section
→ If no clear user flow: ERROR "Cannot determine user scenarios"
5. Generate Functional Requirements
→ Each requirement must be testable
→ Mark ambiguous requirements
6. Identify Key Entities (if data involved)
7. Run Review Checklist
→ If any [NEEDS CLARIFICATION]: WARN "Spec has uncertainties"
→ If implementation details found: ERROR "Remove tech details"
8. Return: SUCCESS (spec ready for planning)
```

## ⚡ Quick Guidelines
- ✅ Focus on WHAT users need and WHY
- ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
- 👥 Written for business stakeholders, not developers
### Section Requirements
- **Mandatory sections**: Must be completed for every feature
- **Optional sections**: Include only when relevant to the feature
- When a section doesn't apply, remove it entirely (don't leave as "N/A")
### For AI Generation
When creating this spec from a user prompt:
1. **Mark all ambiguities**: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
2. **Don't guess**: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
3. **Think like a tester**: Every vague requirement should fail the "testable and unambiguous" checklist item
4. **Common underspecified areas**:
- User types and permissions
- Data retention/deletion policies
- Performance targets and scale
- Error handling behaviors
- Integration requirements
- Security/compliance needs

## User Scenarios & Testing *(mandatory)*
### Primary User Story
Healthcare professionals using KiviCare (WordPress-based clinic management system) need to access and manage comprehensive patient care data through a robust REST API. This includes managing clinic operations, patient records, appointment scheduling, medical encounters, prescriptions, and billing - all while maintaining data integrity across the existing 35-table database structure.
### Acceptance Scenarios
1. **Given** a doctor is authenticated via JWT token, **When** they create a new patient via `/wp-json/kivicare/v1/patients`, **Then** the system creates entries in wp_users and wp_kc_patient_clinic_mappings tables and returns the patient ID
2. **Given** a patient has an appointment, **When** a doctor creates an encounter via `/wp-json/kivicare/v1/encounters`, **Then** the system links it to wp_kc_patient_encounters and allows prescription creation
3. **Given** multiple doctors from the same clinic, **When** one doctor updates a patient's medical history, **Then** other doctors with clinic access can retrieve the updated data via the patients endpoint
4. **Given** an encounter is completed, **When** the doctor finalizes the visit, **Then** the system automatically generates billing data in wp_kc_bills with proper encounter linkage
5. **Given** a receptionist role user, **When** they access appointment endpoints, **Then** they can manage appointments but cannot access sensitive medical data per role-based permissions
### Edge Cases
- What happens when WordPress database connection fails during API calls?
- How does system handle concurrent updates to the same appointment or encounter record?
- What occurs when patient data needs to be exported or transferred between different clinic systems?
- How does the API respond when KiviCare base plugin is deactivated?
- What happens when JWT tokens expire during long-running operations?
## Requirements *(mandatory)*
### Functional Requirements
- **FR-001**: System MUST provide REST API endpoints for all core KiviCare operations (clinics, patients, doctors, appointments, encounters, billing)
- **FR-002**: System MUST authenticate users via JWT tokens based on WordPress wp_users table with role-based access control
- **FR-003**: System MUST maintain data integrity across existing KiviCare database schema (35 tables) without breaking existing WordPress plugin functionality
- **FR-004**: System MUST support four user roles: administrator (all operations), doctor (patient care, encounters), patient (own data, appointments), receptionist (appointments, basic patient data)
- **FR-005**: System MUST provide CRUD operations for clinics (wp_kc_clinics), patients (wp_users + mappings), and appointments (wp_kc_appointments)
- **FR-006**: System MUST enable doctors to create patient encounters (wp_kc_patient_encounters) linked to appointments with prescription management
- **FR-007**: System MUST generate billing records (wp_kc_bills) automatically from completed encounters with payment tracking
- **FR-008**: System MUST provide reporting endpoints for appointments, revenue, patients, and doctor statistics
- **FR-009**: System MUST implement proper error handling with standardized HTTP status codes and JSON error responses
- **FR-010**: System MUST include caching mechanisms for frequently accessed data (patient encounters, appointment schedules) with configurable TTL
- **FR-011**: System MUST verify KiviCare base plugin dependency and fail gracefully if not available
- **FR-012**: System MUST support clinic-specific data isolation ensuring users only access data from their authorized clinics
### Key Entities *(include if feature involves data)*
- **Clinic**: Healthcare facility (wp_kc_clinics) with admin, contact details, specialties, and operational settings
- **Patient**: Individual receiving care (wp_users + wp_kc_patient_clinic_mappings) with demographics, medical history, and clinic associations
- **Doctor**: Healthcare provider (wp_users + wp_kc_doctor_clinic_mappings) with specialties, schedules, and clinic permissions
- **Appointment**: Scheduled healthcare visit (wp_kc_appointments) linking patient, doctor, clinic with time slots and service mappings
- **Encounter**: Actual medical consultation (wp_kc_patient_encounters) documenting diagnosis, treatment, and prescriptions
- **Prescription**: Medication orders (wp_kc_prescription) linked to encounters with dosage, frequency, and instructions
- **Bill**: Financial record (wp_kc_bills) for services rendered with payment tracking and encounter linkage
- **Service**: Medical services offered (wp_kc_services) with pricing and availability for appointment booking
