Using HL7 FHIR to achieve interoperability in patient health record

Abstract

The rapid growth and acceptance of Electronic Health Records (EHRs) and standards to exchange EHRs have improved various aspects of health practices and patient care. However, the data captured in an EHR is only accessible to the providers and specialists within an organization, but not the patient. The concept of a Personal Health Record (PHR) is to allow the patients to record and manage their health data beyond EHR and if possible, see the EHR data in the PHR. Experts agree that bi-directional communication between the PHR and EHR allows the PHR to be more effective and a valuable tool for both the providers and patients. Communicating near real-time patient recorded data in PHR with an EHR will allow the provider(s) to make appropriate clinical decisions and patients can see any changes to his/her diagnostics or treatment plans. This research explores and critically analyzes HL7 FHIR to design and prototype an interoperable mobile PHR that conforms to the HL7 PHR Functional Model and allows bi-directional communication with OpenEMR.
