  • Title: The use of sedative-hypnotic drugs in a university teaching hospital.
    Author: O'Reilly R, Rusnak C.
    Journal: CMAJ; 1990 Mar 15; 142(6):585-9. PubMed ID: 2369436.
    Abstract:
    We reviewed the charts of 476 patients admitted to a university teaching hospital to determine whether sedative-hypnotic drugs (SHDs) were being used excessively and to examine the use of SHDs as hypnotics. The frequency of medical and surgical indications for barbiturates and benzodiazepines or other minor tranquillizers as well as the use of such drugs were compared among different groups of patients and specialty wards. Of the patients 29% had a regular order and 40% had a PRN order; only 77% of the PRN orders were administered. A total of 215 patients (45%) received an SHD during their hospital stay, and 160 (34%) received the drug as a hypnotic. Medical indications accounted for 49% of the regular orders but only 2% of the PRN orders; moreover, 89% of all the PRN orders were for insomnia. On average, patients receiving SHDs as hypnotics were older (p less than 0.05) and stayed longer in hospital (p less than 0.01) than those who did not; however, no patient on the geriatric or pediatric ward received an SHD as a hypnotic during the hospital stay. The differences in use between patient groups may have been influenced by orientation of ward staff. Physicians should review their rationale for prescribing hypnotics and avoid routine orders on admission.
