Global prevalence of antidepressant utilization in the community: A protocol for a systematic review

Abstract

ABSTRACTBackgroundAntidepressant drugs are the most frequently prescribed medication for mental disorders. They are also used off-label and for non-psychiatric indications. Prescriptions of antidepressants have increased in the last decades, but no systematic review exists on the extent of their use in the community.Methods and analysisWe will conduct a systematic review to estimate the prevalence of antidepressant use in the community. We will search for studies published from 2010 in the Embase and MEDLINE databases. Study selection (by title/abstract and full-text screening) and data extraction for included studies will be independently conducted by pairs of reviewers. We will then synthesize the data on the prevalence of antidepressant use in individuals living in the community. If possible, we will perform a meta-analysis to generate prevalence-pooled estimates. If the data allows it, we will conduct subgroup analyses by antidepressant class, age, sex, country or other sociodemographics. We will evaluate the risk of bias for each included study through a quality assessment using the Joanna Briggs Institute Critical Appraisal tool: Checklist for Studies Reporting Prevalence Data. DistillerSR software will be used for the management of this review.Ethics and disseminationEthical approval is not required for this review as it will not involve human or animal subjects. The findings of our systematic review will be disseminated through publications in peer-reviewed journals, the Qualaxia Network (https://qualaxia.org), presentations to international conferences on mental health and pharmacoepidemiology, as well as general public events.PROSPERO registration detailsCRD42021247423
