Coded Dynamic Consent framework using blockchain for healthcare information exchange.

As personalized digital healthcare is attracting attention, recognition of data sovereignty has been essential in healthcare data exchange. Dynamic consent is a new approach that patients enable to tailor and manage their consent. It expands patients’ autonomy by giving the right to intervene in the healthcare data exchange process. This study proposes a Coded Dynamic Consent framework based on blockchain. We developed five design criteria to support dynamic consent and represent consent preferences as a coded format. The framework ensures data sovereignty and autonomy of a data provider so that patient-centered healthcare data exchange environment could be achieved.
