Patient Management
A comprehensive healthcare patient management system built with Spring Boot and PostgreSQL. Features role-based access control, appointment scheduling, medical history tracking, and audit logging for regulatory compliance.
Overview
Healthcare software has unique requirements: strict data privacy regulations, audit trails for every change, and reliability that can literally be life-critical. This project implements a patient management system that addresses these challenges.
The system supports multiple user roles (doctors, nurses, administrators, patients) with fine-grained permissions, ensuring that users only see data relevant to their role while maintaining a complete audit trail.
Key Features
Patient Records
Complete patient profiles with demographics, medical history, allergies, medications, and visit history.
Appointment Scheduling
Calendar-based scheduling with conflict detection, reminders, and waitlist management.
Role-Based Access Control
Fine-grained permissions with hierarchical roles. Doctors see different data than nurses or admins.
Audit Logging
Every data access and modification is logged with timestamp, user, and before/after values for compliance.
Security & Compliance
Data Encryption: All sensitive data is encrypted at rest using AES-256. Database connections use TLS 1.3. Passwords are hashed with bcrypt.
GDPR Compliance: Built-in support for data subject access requests, right to erasure (with medical record retention exceptions), and data portability exports.
The audit log captures over 40 different event types, enabling complete reconstruction of any patient's data history for regulatory audits.
Tech Stack
What I Learned
Building healthcare software taught me about the intersection of technology and regulation. Every feature decision must consider privacy implications, audit requirements, and potential misuse scenarios.
I also learned about implementing complex authorization logic with Spring Security, designing database schemas for audit trails, and the importance of thorough testing in safety-critical systems.
