A Multi-center Real-world Study of Benzodiazepines and Z-drugs Prescription in Psychiatric Clinic, and the Effectiveness of Electronic Interventions on Their Standardized Prescription of These Drugs

Benzodiazepines (BZDs) and Z-drugs are commonly used sedative and hypnotic drugs in psychiatry. A small number of studies have suggestted that there may be improper use or even abuse in recent years. Long-term use of BZDs and Z-drugs may have the risk of impairing memory, respiratory depression, and increasing accidents risk. At present, there is no risk investigation on psychiatric BZDs and Z-drugs abuse in China, and many psychiatric practitioners lack of knowledge on the standard use of BZDs and Z-drugs. The aim of this study was to understand the use of benzodiazepines in psychiatric outpatient clinics in China and to develop a BZDs and Z-drugs standardized use electronic intervention guidebook and to verify the effectiveness of this electronic intervention in reducing the use of BZDs and Z-drugs in psychiatric outpatient clinics and improving clinical efficiency. Through retrospective surveys and focus interview groups, the study was conducted to understand the use of BZDs and Z-drugs and related factors of abuse in psychiatric outpatient clinics in Shanghai, Hunan, Sichuan, Wuhan and Jiangsu provinces. Based on the consensus and guidelines of domestic experts, BZDs and Z-drugs standardized electronic intervention was used. The real-world randomized controlled research method was combined with electronic content push and periodic electronic evaluation to evaluate the effectiveness of the intervention in reducing the use rate of psychiatric BZDs and Z-drugs and improving clinical efficiency. The research can deeply understand the use of BZDs and Z-drugs in domestic psychiatry and form an effective BZDs and Z-drugs standardized electronic intervention manual, which will provide practical value for regulating domestic BZDs and Z-drugs in the future.
