How the Problem Was Solved

Technology Stack:

Java (Spring Boot) for backend, React for frontend, and PostgreSQL for data storage.

Key Features:

• • Secure Data Exchange (HL7/FHIR compliance)
  • Role-based Access Control for different types of medical staff
  • Patient Portal for viewing medical history

Approach:

• Standards Compliance: Adopted FHIR standards for patient data to ensure interoperability.
• Robust Security: Implemented OAuth 2.0 for secure authentication and granular authorization.
• High Availability: Deployed in a clustered environment to handle critical healthcare data and minimize downtime.

The Results

Impact on the Business:

• • Improved patient care coordination and reduced administrative overhead.
  • Increased user satisfaction among medical staff due to faster data retrieval.

Cost:

• ~250K USD
• Higher initial development cost due to compliance requirements and security audits.

Time:

• Development spanned 9 months, including a 2-month pilot with two clinics.

Lessons Learned

• What Went Well:
  • Early alignment with industry standards (FHIR, HL7) streamlined interoperability.
  • Engaging end-users (nurses, doctors) during the design phase improved the final product.
• What We Would Do Differently Next Time
  • Allocate more time for security penetration testing before production.
  • Provide more comprehensive training resources for medical staff post-launch.
