Studying the impact of patient drug profiles in an HMO.

The objectives of the study were to determine if a drug profile quantitatively and qualitatively influenced various aspects of drug utilization. A group of 1,632 medically indigent persons enrolled in the Kaiser Health Plan constituted the study population. This population received completely prepaid medical care including drug services from the Kaiser Medical Care Program. A computer-based chronological and monthly updated listing of drugs ordered and prescriptions received was provided as the front page of the centralized outpatient medical chart for a randomly selected half of the study population for a full year. Duplicate and bound copies of these patient drug profiles were also provided each outpatient pharmacy. The findings indicated the presence of the drug profile did not quantitatively or qualitatively affect prescription receipt of the group with the profile. Although the findings must be viewed in the contexts of the population served and the medical care setting, the findings strongly indicate the need for additional research to assess additional forms of drug profiles and under conditions not addressed by this study.
