MediLinker (Blockchain)

Problem

Electronic medical record(EMR) systems in the US lack seamless interoperability, resulting in incomplete medical histories and preventing patients from being the ultimate arbiters of their health data.

Solution

To develop our blockchain solution, called MediLinker, we formed an interdisciplinary group including UT researchers and students from multiple departments (including members of the ETA Team) to provide the UX/UI, technical, and clinical perspectives needed to tackle the complex use-cases found in healthcare settings. We identified clinical use-cases such as patient enrollment in multiple facilities and consenting to share medical data to guide MediLinker’s design. To manage the patient’s self-sovereign identities, we leveraged the Hyperledger Indy framework to store the patient’s decentralized identifiers(DIDs) and their verifiable credentials for provider patient relationships.

Impact

Empowering patients with self-sovereign data is at the core of patient-centric healthcare.

In this project the data was medical records but the potential for controlling, but not modifying, your credentials extends far beyond that. For example, the same process could be used for school transcripts and government issued IDs. This opens doors for a universal student record of accomplishment.
