The incidence of 10 selected hospital pharmacy programs in short-term hospitals which contained a pharmacy was surveyed. A short questionnaire was mailed to a national sample of 738 hospitals. The 10 programs surveyed were: unit dose drug distribution; pharmacy-prepared i.v. admixtures; pharmacy-controlled drug administration; radiopharmaceutical dispensing; drug usage review; use of computers in the dispensing process; 24-hour pharmacy service; participation in group purchasing; pharmacy operation of central supply; and pharmacists' authority to select the brand or supplier of drugs. In addition, the volume of drug and supply purchases was determined. A large number of pharmacies (41%) belonged to a group purchasing plan, and a high percentage (67%) reported that pharmacists had authority to select the source of supply for all drug orders unless noted otherwise by the prescriber. Less than 10% of the hospitals had both complete unit dose drug distribution and intravenous admixture programs; an additional 10% had implemented such programs partially. Only 17% of the pharmacies in large hospitals were open 24 hours a day. Computer-assisted medication dispensing was used by 13% of the large hospitals and 5% of the small hospitals. Total pharmacy purchases for all short-term hospitals in 1974 was estimated to be 1.5 billion dollars.
