Health Record Solutions: A Developer Guide

Health Record Solutions are software platforms that manage electronic patient information across clinical and administrative workflows. These platforms treat patient records as structured data, making information easier to search, validate, exchange, analyze, and reuse across applications. Developers building these platforms must address interoperability, healthcare data models, security, authorization, terminology, auditability, and integration with existing Electronic Health Record (EHR) systems.

A typical health record platform uses a layered architecture, with presentation layers handling user interactions, application services implementing business rules, an integration layer managing external systems, and a data layer managing persistence and analytics workloads. The data model is crucial, with developers avoiding isolated tables without considering interoperability.

HL7's Fast Healthcare Interoperability Resources (FHIR) provides a standard for exchanging healthcare information electronically, featuring RESTful APIs, structured resources, and standardized data types.

Developers should define interoperability requirements before implementing individual features. Security must be enforced at every appropriate layer, including authentication and authorization. FHIR APIs, implemented as GET /fhir/Patient/12345 or GET /fhir/Observation?patient=12345, enable communication with EHRs and other healthcare applications.

Integration architectures must identify each system and document source systems, integration adapters, transformations, validations, internal services, applications, and databases. Terminology mapping, validation strategies, and adherence to standards like the ONC's USCDI v7 ensure consistent healthcare data.
