Leveraging XDS-I and PIX workflows for validating cross-enterprise patient identity linkage

Document exchange communities set the ground for cross-organization cooperation. They enable the exchange of patient´s documents across distinct health organizations. However, there are various challenges that must be overcame before deploying such communities, for instance the construction of the Enterprise Master Patient Index (EMPI) which maps the several patient identifiers of each domain. This paper describes the development of an interoperable distributed system that expedites the exchange of documents by taking care of the patient identities autonomously. The system automatically builds the EMPI leveraging the healthcare workflow (based on PIX and XDS-I) for validating the automatic linkages of the patient identifiers. The human validation is a consequence of user´s interaction with cross-domain documents: distributing and attenuating the validation effort.
