Preprints with The Lancet is a collaboration between The Lancet Group of journals and SSRN to facilitate the open sharing of preprints for early engagement, community comment, and collaboration. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early-stage research papers that have not been peer-reviewed. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. The findings should not be used for clinical or public health decision-making or presented without highlighting these facts. For more information, please see the FAQs.

Background: We aimed 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.
Methods: In this systematic rapid review and meta-analysis we searched MEDLINE, Embase, and PsycINFO between inception and 23 March 2020 for observational and experimental studies examining the impact on mental health of epidemic outbreaks on HCWs. We assessed risk of bias for each individual study and used GRADE to ascertain the certainty of the evidence. We pooled data using random-effects meta-analyses to estimate the prevalence of specific mental health problems.
Results: We identified 61 studies. The pooled prevalence was higher for anxiety (45%, 95% CI 21 to 69%), followed by depression (38%, 95% CI 15 to 60%), acute stress disorder (31%, 95% CI 0 to 82%), burnout (29%, 95% CI 25 to 32%), and post-traumatic stress disorder (19%, 95% CI 11 to 26%). Based on 37 studies, we identified sociodemographic, social, and occupational factors associated with the likelihood of developing those problems. Five studies reported interventions for frontline HCW. Two educational interventions increased confidence in support and training, pandemic self-efficacy, and interpersonal problems solving (very low certainty). One multifaceted intervention improved anxiety, depression, and sleep quality (very low certainty). Two additional interventions (multifaceted and psychotherapy) did not assess their impact.
Interpretation: The prevalence of mental health problems was high both during and after the outbreaks. In light of the limited evidence regarding the impact of interventions to tackle mental health problems in HCWs, the risk factors identified in this study represent important targets for future interventions.
Funding: No specific funding for this study. IRC is a recipient of a Miguel Servet Fellowship (project number CP17/00017) funded by the Spanish Government.
