Objective:
To evaluate the effect of COVID-19 lockdown on the prescription of benzodiazepines by gender, age and district health departments.
Design:
Longitudinal observational study.
Location:
Primary care. Asturias (Spain) health district V.
Participants:
People over 15 years of age with filled benzodiazepine prescriptions in between 2017 and 2020.
Main Measurements:
Benzodiazepine DHD (defined daily dose per 1000 habitants) mean difference between the period defined as pre-lockdown and lockdown. Additionally, the difference was adjusted for gender, sex and district health department and also with the interaction among them.
Results:
DHD mean pre-lockdown was 131.3 and 139.5 in the lockdown; this difference was significant in the global analysis (95% CI: 4.1-12.1). There was an increase in the DHD mean in the 60-74 age group (95% CI: 2.28-21.42), in the group over 90 years old (95% CI: 21.31-40.63) and in women (95% CI: 3.51-14.59). Finally, a decrease in the DHD mean of V11 (95% CI: -29 to -0.66) and V14 (95% CI: -54.28 to -25.04) district health departments was observed.
Conclusions:
Certain subgroups show a change in the pattern of benzodiazepine prescription without being able to relate this to the lockdown. We believe that there could be some inertia in the prescription of psychiatric medication according to the biopsychosocial characteristics of the patients; it is important to detect this in order to avoid the medicalization of psychological disorders.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
