Analysis of mental health effects among nurses working during the COVID-19 pandemic: a systematic review

Introduction: Health professionals have suffered negative consequences during the COVID-19 pandemic. No review has specifically addressed the impact of the pandemic on the mental health of nurses exclusively according to the work context. Aim: To analyse the impact of the COVID-19 pandemic on the mental health of nurses who have worked in hospitals, primary care centres and social health centres. Method: PubMed, CINAHL, PsychINFO and Cochrane databases were searched (Prospero number: CRD42021249513). Out of 706 papers, 31 studies (2020–2021) were included in the systematic review. A qualitative synthesis method was used to analyse the data. Results: Most studies were conducted in hospitals or frontline settings. The prevalence of moderate-to-severe symptoms was for anxiety 29.55%, depression 38.79%, posttraumatic stress disorder 29.8%, and insomnia 40.66%. Discussion: This review highlights the mental health effects among nurses working in acute hospital settings. It also evidences a data gap on mental health effects among nurses working in primary health care and in nursing homes. Implications for practice: In the post phase of the pandemic, there is an urgent need to assess and respond to the impact on the mental well-being of nurses, and to monitor international policies for the improvement of nurses’ working conditions.
