title: Effect of pharmacist interventions on medication use and cost in hospitalized patients with or without HIV infection.
abstract: Pharmacotherapeutic interventions and drug acquisition costs in HIV-positive and HIV-negative patients on a hospital medical service were studied. In November and December 1995, HIV-positive and HIV-negative patients were randomly selected and matched on the basis of admission date. Pharmacotherapeutic interventions were recorded by a pharmacist until the time of discharge. Drug acquisition costs were obtained through records of medications ordered. The two patient groups were compared with respect to length of stay (LOS), number and cost of medications, and number of interventions. HIV-positive patients had significantly more medication orders and required more interventions than HIV-negative patients. Mean LOS was not significantly different. HIV status and number of medications were significantly associated with requiring five or more interventions. Drug acquisition costs were significantly higher in the HIV-positive group. The mean pharmacist-attributed cost saving per patient was $134 for HIV-positive patients and $27 for HIV-negative patients. HIV-positive patients required more interventions and consumed more medication resources than HIV-negative patients. Pharmacist interventions produced drug acquisition cost savings for both groups, with more savings being realized for positive patients.
