PHARMACIST-MANAGED MEDICATION REVIEW IN A MANAGED CARE SYSTEM

A medication-review service at a managed care facility was studied. The service, developed in 1991, provides in-depth analysis of medication use and patient consultation by a pharmacist. Patients are seen by referral. During a visit, the pharmacist reviews each medication for patterns of use, clinical response, and adverse effects and if necessary teaches the patient how to use the drugs more appropriately. The pharmacist may change some aspect of the prescription and may schedule follow-up visits. The investigators reviewed data on (1) medication-related problems for all new patients seen by the pharmacist during the first 12 months of the service, (2) patient demographics for the first 23 months, (3) utilization of the service and pharmacist productivity for the first 23 months, (4) utilization of medications and health care services in a representative subset of patients 12 months before and after they used the service, and (5) costs. A total of 2720 medications were reviewed during months 1-12. On average, 64.9% of the drugs reviewed each month were problematic. A total of 836 patients were seen during the first 23 months; most of the referrals were from physicians. The patients averaged 2.6 diagnoses and 4.7 drugs each and were not dominated by any one age group, gender, diagnosis, or drug therapy. A representative subgroup showed reductions in the number of unscheduled physician visits; urgent care visits, emergency room visits, and hospital days; a savings of $644 per patient per year was calculated. Patients used fewer health services during the year after they began participating in a pharmacist-managed medication-review program.
