Purpose: When used appropriately, benzodiazepines and z-drugs (BZRA) can be effective for the short-term management of acute severe anxiety or insomnia1.
The MMUH formulary night sedation choice was agreed for use in consultation with Department of Adult Psychiatry and Department of Medicines for The Elderly2.
An audit of night sedation use was carried out in 2008 to assess the compliance with the MMUH formulary. A repeat audit was carried in May 2018.
To assess compliance of night sedation prescribing with the Hospital formulary and to compare results with 2008 audit.
Methods: The Clinical Pharmacy Service conducted a one day “snap shot” audit.
• All in patient drug charts were reviewed
• Data collected included the drug name, dose and frequency, whether the patient was admitted on a non-formulary night sedative and if a stop date was indicated.
• 2018 results were analysed and compared with 2008 results
Results: 599 patient’s drug charts were reviewed by the Clinical Pharmacy Service.
97 (16%) patients were prescribed night sedation. 39 (40%) of the prescriptions were prescribed in the regular section. No prescription for night sedation had a stop date. 46 (47%) of the patients were prescribed a MMUH formulary agent, temazepam or zolpidem; 44 (96%) of these were prescribed zolpidem. 44 (45%) of patients were prescribed zopiclone, of which, 11 (25%) of these were prescribed after admission to the MMUH.
Conclusion: In 2018, 16% of patients were prescribed night sedation versus 40% of patients in 2008.This is a positive finding. However, in 2018, 47% of patients were prescribed a formulary choice versus 84% in 2008. These results highlight the need for regular review of the hospital formulary agents in conjunction with the relevant consultants.
