System and method for generating de-identified health care data
First Claim
1. A method for creating a unique alias associated with an individual identified in at least a first health care database, wherein the first health care database contains at least one record comprising a plurality of identification fields and a health care field that comprises health care data associated with the individual, the method comprising:
- (a) selecting a first record within the first health care database, wherein the first record comprises a first plurality of identification fields and a first health care field that comprises health care data associated with the individual;
(b) selecting a first subset of the first plurality of identification fields within the first record;
(c) creating a first concatenated identifier using the selected first subset of identification fields;
(d) defining a first unique alias by encrypting at least a part of the first concatenated identifier; and
(e) transmitting the first unique alias and the first health care field to a data store that stores the first unique alias and the first health care field.

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 data 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 data store with the at least one health care field from the selected record of the first data store.

19. A method for creating a unique alias associated with an individual identified in at least a first health care database, wherein the first health care database contains at least one record comprising a plurality of identification fields and a health care field that comprises health care data associated with the individual, the method comprising:
-
(a) selecting a first record within the first health care database, wherein the first record comprises a first plurality of identification fields and a first health care field that comprises health care data associated with the individual; (b) selecting a first subset of the first plurality of identification fields within the first record; (c) creating a first concatenated identifier using the selected first subset of identification fields; (d) defining a first unique alias by encrypting at least a part of the first concatenated identifier; and (e) linking the first health care field with a plurality of health care fields taken from one or more other records using the first unique alias.

20. A method for using a unique alias associated with an individual identified in health care databases, wherein each health care database contains at least one record that comprises a plurality of identification fields and a health care field that comprises health care data associated with the individual, the method comprising:
-
(a) receiving a first unique alias and a first health care field, wherein the first unique alias was created by performing the steps of; i. selecting a first record within a first health care database, wherein the first record comprises a first plurality of identification fields and a first health care field that comprises health care data associated with the individual; ii. selecting a first subset of the first plurality of identification fields within the first record; iii. creating a first concatenated identifier using the selected first subset of identification fields; and iv. creating the first unique alias by encrypting at least a part of the first concatenated identifier; (b) receiving a second unique alias and a second health care field, wherein the second unique alias was created by performing the steps of; i. selecting a second record within a second health care database, wherein the second record comprises a second plurality of identification fields and a second health care field that comprises health care data associated with the individual; ii. selecting a second subset of the second plurality of identification fields within the second record; iii. creating a second concatenated identifier using the selected second subset of identification fields; and iv. creating the second unique alias by encrypting at least a part of the second concatenated identifier; (c) linking the first health care field with the second health care field using the first unique alias and the second unique alias; and (d) performing health care data analysis using the linked first and second health care fields.
