Community-hospital pharmacist detection of drug-related problems upon patient admission to small hospitals.

A method was developed to increase community-hospital pharmacist consultation on patient drug use in order to detect drug-related problems upon patient admission to the hospital. A medication history was takenon criteria-selected patients admitted to two hospitals in distant, but similar, geographically small and isolated areas. Tho total number of patients selected was 392. Information about prior drug use was obtained from participating community pharmacists and their patient prescription records and medication profiles. It was found by pharmacist-acquired drug histories that one of five criteria-selected patients had a preexisting drug-related problem that the admitting physician acknowledged probably contributed to the admission and necessitated professional and patient communication. These problems included: adverse response to prescribed therapy, misuse of medication or noncompliance, effect of diet on therapy, patient treatment by more than one prescriber, and therapeutic ineffectiveness or inappropriateness of prescribed therapy. Drug histories were not obtainable in 25.6% of the patients.
