Community-Based Pharmaceutical Care: A Controlled Trial
Principal Investigator:Morris Weinberger, Ph.D., Indiana University, Indianapolis, IN 46202-5167
Summary: The purpose of this study was to develop algorithms to facilitate pharmaceutical care for the treatment of asthma. A randomized controlled trial, with 460 patients in a pharmacy intervention group and 2 control groups (peak flow monitoring, usual care), was undertaken. The pharmacy intervention group was given patient-specific clinical information displayed on their computer workstations when filling prescriptions. Asthma patients receiving the pharmaceutical care program had more emergency department visits and hospitalizations for acute exacerbation than the usual care group. Authors concluded that while the pharmaceutical care program demonstrated substantial improvement in both medication compliance and health related quality of life at 6 months and sustained at one year, similar levels of improvement were observed in both control groups.

Impact of Prospective Drug Use Review on Health Outcomes
Principal Investigator:Frank M. Ahern, Ph.D., Pennsylvania State University, University Park, PA 16802
Summary:, The purpose of this study was to compare two different models of outpatient prospective drug utilization review (ProDUR) programs in the State of Pennsylvania. One model allowed active participation by a pharmacist in the process while the other did not. The study aimed to 1) conduct a descriptive epidemiological analysis of psychotropic drug use, prescribing patterns, and yield of ProDUR interventions; 2) compute estimates of drug-related outcome measures; and 3) evaluate the independent effects of two different ProDUR procedures on health outcomes. The investigators used data from the Pharmaceutical Assistance Contract for the Elderly (PACE) and Medicaid. While findings suggest that both ProDUR systems had an impact on prescription drug utilization and on exposure to inappropriate drug use, the program that allowed active participation by a pharmacist had a more positive impact on utilization measures than the program that did not allow such participation.
