Paper Abstract:
|
Electronic health records (EHR) are usually maintained in a centralized way by health organizations, leaving aside an integration between different health organizations to view the complete health history of a given patient. This lack of EHR integration prevents patients and physicians to have a unified view of medical records, which are often stored in different health organizations. Recent studies have proposed using blockchain technology in distributed architectures due to its security and integration properties. This paper proposes an application architecture using blockchain technology for distributed EHR integration, which is called UniRec (Unified Medical Records), seeking to understand its effectivity, performance and applicability through a prototype, which is later evaluated in a test scenario. The prototype proved to be effective for distributed EHR integration, allowing one healthcare institution to view an EHR previously added by a different institution, after being granted permission. During the test scenario execution, an average response time of 2.77 seconds was measured. As future work, we propose applying the UniRec in a larger scale and also with different blockchain platforms, as well as studying the miners reward strategy for UniRecs network. |
