Psychiatric medication prescribing during COVID (PsyDUC)

A national registry-based time series study was performed with out-patient prescription data from the national pharmacy database Genees- en hulpmiddelen Informatie Project, from the Dutch National Health Care Institute (Zorginstituut Nederland). A list of dispensed prescriptions was requested for medications with Anatomical Therapeutic Chemical (ATC) codes that had psychiatric conditions as their main indication according to the Dutch pharmacotherapy formulary. Data were included from a period from 1 year before the COVID-19 pandemic and for 2 years during the pandemic. Data were provided in aggregated form and stratified by ATC code, dispensing calendar week, patient demographics (age and gender) and prescription type (incident or repeated prescriptions).
