An umbrella review and meta-analysis of 87 meta-analyses examining healthcare workers' mental health during the COVID-19 pandemic.

During the COVID-19 pandemic, healthcare workers (HCWs) experienced several changes in their work (e.g., longer hours, new policies) that affected their mental health. In this study, an umbrella review and meta-analysis of meta-analyses was conducted to examine the prevalence of various mental health problems experienced by HCWs during the COVID-19 pandemic. We conducted a systematic review searching PubMed, EMBASE, PsycINFO, Cochrane Library, and Scopus databases (PROSPERO: CRD42022304823). We performed a meta-analysis to summarize prevalence of different mental health problems and examined whether these differed as a function of job category, sex/gender, sociodemographic index (SDI), and across time. Eighty-seven meta-analyses were included in the umbrella review and meta-analysis, including 1846 non-overlapping articles and 9,400,962 participants. The overall prevalence ratio for the different mental health outcomes ranged from 0.20 for PTSD (95 % CI: 0.16-0.25) to 0.44 for burnout (95 % CI: 0.32-0.56), with ratios for depressive symptoms, anxiety symptoms, psychological distress, perceived stress, sleep problems, and insomnia symptoms falling between these ranges. Follow-up analyses revealed little variation in outcomes across job category, and sex. Prevalence of mental health problems in HCWs was high during the pandemic. Administrators and policymakers worldwide need to address these growing problems through institutional policies and wellness programming.
