Develop a comprehensive Hospital Management System with a secure patient portal. The system should provide an intuitive interface for managing patient records, scheduling appointments, processing insurance claims, and tracking medical supplies. The patient portal should allow patients to view their medical history, schedule appointments, and communicate with healthcare providers securely. The system must adhere to industry-standard security protocols to protect patient data and ensure HIPAA compliance. Ensure integration with external systems such as insurance providers and labs for seamless data exchange. The system should be scalable to accommodate future growth and support multiple locations.
