patientRegistry

patientRegistry is the Master Patient Index component of Leafsprout's Digital Health Suite. It acts as the registrar of patient identifiers and patient demographics pertaining to individuals residing in a given geographic region (e.g., state, province, country), belonging to the same health organization/system or associated with a set of hospitals/clinics that are sharing information about patients. The registry automatically reconciles and links different versions of patient demographics and different identifiers which exist in various hospitals/clinics within the region or in different clinical information systems within an enterprise. For example, the Registry can recognize the fact that Liz Browne ID=654217 in Hospital A is the same person as Elizabeth Browne ID=33765 in Hospital B, Elizabeth Brown ID=DZ3345 in the EMR System, and Elisabeth Brown ID= 654-L4V in the Clinic.

The result is a clean and trusted index of patient data which contributes to the patient safety, enhances the quality of care and ultimately reduces the cost of healthcare delivery.
