Linking entity records based on event information
View Patent ↗A system links data objects associated with a common event and includes at least one processor. The system compares data objects associated with an entity and corresponding to a plurality of events for the entity, wherein the data objects are stored within a plurality of different source systems. Candidate data objects associated with a common event for the entity are identified based on the comparing. The candidate data objects are linked to form a set of data objects representing the common event for the entity. Embodiments of the present invention further include a method and computer program product for linking data objects associated with a common entity.
1. A computer-implemented method of linking data objects associated with a common event for an entity comprising:
comparing data objects associated with an entity and corresponding to a plurality of events for the entity, wherein the data objects are stored within a plurality of different source systems, wherein data objects are compared in a pair-wise fashion to determine a likelihood score that indicates a likelihood of compared data objects being associated with a common event, wherein determining the likelihood score comprises comparing information in fields of the data objects pertaining to one or more from a group of: dates, locations, healthcare providers, medical procedures, medical diagnoses, laboratory tests, and medications, wherein each field is associated with one or more weight values corresponding to one or more matching levels of the information in the field, wherein higher weight values are associated with higher matching levels of the compared information in the fields of the data objects, and wherein the likelihood score is determined by adding one or more weight values determined according to the one or more matching levels of the information in the fields of the compared data objects;
identifying candidate data objects associated with a common event for the entity based on the comparing, wherein candidate data objects are identified as associated with a common event based on the likelihood score exceeding a threshold, and wherein the common event includes one of a stay at a medical facility, an external laboratory test, and a medical insurance claim; and
linking the candidate data objects to form a set of data objects, wherein each of the linked candidate data objects in the set of data objects is associated with the common event for the entity.
2. The computer-implemented method of claim 1 , wherein the entity includes a patient.
3. The computer-implemented method of claim 1 , further comprising:
identifying candidate events through time associated with a common episode for the entity; and
linking the candidate events to form a set of events representing the common episode for the entity.
4. The computer-implemented method of claim 1 , wherein the set of data objects form a resolved clinical event.
