An evaluation of a ward pharmacy service.

An evaluation of a ward pharmacy service showed: 1. Its introduction led to a 40-50% reduction in errors and ambiguities of prescribing. 2. It assisted in the safe and more effective use of medicines in hospitals. 3. Medical staff particularly valued the safety checking applied to their prescriptions and the patient's total medication profile, and the opportunity of seeking information about drugs. Nursing staff most appreciated the checking and clarifying elements which assisted during the administration of drugs, the promotion of the most effective use of medicines and the opportunity of discussing problems of drug therapy.
