1. A computer implemented method for automatically selecting an optimal control cohort, the computer implemented method comprising:
- selecting attributes based on patient data;
clustering of treatment cohort records to form clustered treatment cohorts;
scoring control cohort records to form potential control cohort members; and
selecting the optimal control cohort by minimizing differences between the potential control cohorts members and the clustered treatment cohorts.

Abstract
A computer implemented method, apparatus, and computer usable program code for automatically selecting an optimal control cohort. Attributes are selected based on patient data. Treatment cohort records are clustered to form clustered treatment cohorts. Control cohort records are scored to form potential control cohort members. The optimal control cohort is selected by minimizing differences between the potential control cohort members and the clustered treatment cohorts.

14. An optimal control cohort selection system comprising:
-
an attribute database operatively connected to a clinical information system for storing patient records including attributes of patients; a server operably connected to the attribute database wherein the server executes a data mining application and a clinical control cohort selection program wherein the data mining application selects specified attributes based on patient data, clusters treatment cohort records based on the specified attributes to form clustered treatment cohorts, and clusters control cohort records based on the specified attributes to form clustered control cohorts; and
wherein the clinical control cohort selection program selects the optimal control cohort by minimizing differences between the clustered control cohorts and the clustered treatment cohorts. - View Dependent Claims (15, 16)
