Integration of OpenMRS with OpenEMPI
...
Introduction
In addition to patient-centered data, electronic medical record, laboratory, radiology and other such health care systems need to manage patient identity and demographic information (such as data of birth, gender, and ethnicity). To improve the quality of care provided to patients, these different health care systems must be integrated and share patient data, thereby providing a comprehensive view of a patient's health care history across the group of colaborating providers. An "Enterprise Master Person Index" (EMPI) or an "Entity Identification System" (EIS) is used to provide identity management services, including identification of duplicate patients within a single system, identification of the same patient across multiple systems, and automated linkage of new inbound clinical data to existing results. OpenEMPI is an open source EMPI that is currently hosted as a project in the Open Health Tools group and which is currently under active development. A federation of OpenMRS instances can utilize OpenEMPI both for the purpose of maintaining a central registry of patients across sites as well as for the purpose of allowing a given OpenMRS instance to determine what other OpenMRS sites a patient has visited, following the Record Locator model for building an Electronic Health Record (EHR).
Deliverables
Target: The target of this project is to explore the integration of the open source EMPI (OpenEMPI) with OpenMRS. The following is a list of deliverables that are expected from this project.
...
• Extend OpenEMPI to allow it to maintain location/connection information about each participating OpenMRS site so that a given OpenMRS site can not only identify other OpenMRS sites that a patient has visited but also obtain the information needed to contact the other sites and retrieve patient data from them.
