Objectives:To examine the impact of providing healthcare during or after health emergencies caused by viral epidemic outbreaks on healthcare workers´(HCWs) mental health, and to assess the available evidence base regarding interventions to reduce such impact.Design: Systematic rapid review and meta-analysis.Data sources: MEDLINE, Embase, and PsycINFO, searched up to 23 March 2020.
Method:We selected observational and experimental studies examining the impact on mental health of epidemic outbreaks on HCWs. One reviewer screened titles and abstracts, and two reviewers independently reviewed full texts. We extracted study characteristics, symptoms, prevalence of mental health problems, risk factors, mental health interventions, and its impact. We assessed risk of bias for each individual study and used GRADE to ascertain the certainty of the evidence. We conducted a narrative and tabulated synthesis of the results. We pooled data using random-effects meta-analyses to estimate the prevalence of specific mental health problems.
Results:We included 61 studies (56 examining impact on mental health and five about interventions to reduce such impact). Most were conducted in Asia (59%), in the hospital setting (79%), and examined the impact of the SARS epidemic (69%). The pooled prevalence was higher for anxiety (45%, 95% CI 21 to 69%; 6 studies, 3,373 participants), followed by
