System and method for analyzing de-identified health care data
First Claim
1. A system for analyzing de-personalized health care data, comprising:
- (a) a plurality of health care databases, the plurality of health care databases each including at least one record, each record including a de-personalized yet unique patient identifier associated with a patient, whereby the de-personalized patient identifier is a common value identifying a specific patient across a plurality of health care databases that are associated with distinct database systems of different organizations;
(b) one or more processors in communication with a first of the health care databases, and one or more storage devices storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising;
(i) receiving a new record from at least one of the plurality of healthcare databases, the new record comprising a plurality of identification fields uniquely identifying a patient associated with the new record;
(ii) concatenating, into a combined textual representation, text from each of the accessed plurality of identification fields included in the new record,(iii) generating at least one de-personalized yet unique patient identifier associated with the patient by encrypting the concatenated text of the combined textual representation; and
(iv) storing, in a first of the health care databases, at least a portion of the received new record in association with the least one de-personalized yet unique patient identifier.

Abstract
A system and method for creating a unique alias associated with an individual identified in a health care database such that health care data, and particularly pharmaceutical-related data, can be efficiently gathered and analyzed. The system has a first store for storing at least one record where each record includes a plurality of identification fields which when concatenated uniquely identify an individual, and at least one health care field corresponding to health care data associated with the individual. The system also has a second data store, and a processor. The processor selects a record of the first data store, then selects a subset of the plurality of identification fields within the selected record, and concatenates the selected subset of identification fields. Then the processor stores the concatenated identification fields in a record in the second store with at least one health care field from the selected record of the first data store.

2. A method for de-identifying health care data comprising:
-
receiving a new record from at least one of a plurality of health care databases, the new record comprising a plurality of identification fields uniquely identifying a patient associated with the new record; concatenating, into a combined textual representation, text from each of the plurality of identification fields included in the new record, generating at least one de-personalized yet unique patient identifier associated with the patient by encrypting the concatenated text of the combined textual representation, the at least one de-personalized yet unique patient identifier representing a common value identifying the patient across a plurality of health care databases that are associated with distinct database systems of different organizations; and storing, in a first of the health care databases, at least a portion of the received new record in association with the least one de-personalized yet unique patient identifier. - View Dependent Claims (9, 10, 11)

3. A non-transitory computer-readable medium encoded with instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
receiving a new record from at least one of a plurality of health care databases, the new record comprising a plurality of identification fields uniquely identifying a patient associated with the new record; concatenating, into a combined textual representation, text from each of the plurality of identification fields included in the new record, generating at least one de-personalized yet unique patient identifier associated with the patient by encrypting the concatenated text of the combined textual representation, the at least one de-personalized yet unique patient identifier representing a common value identifying the patient across a plurality of health care databases that are associated with distinct database systems of different organizations; and storing, in a first of the health care databases, at least a portion of the received new record in association with the least one de-personalized yet unique patient identifier. - View Dependent Claims (12, 13, 14)
