Factors Affecting the Psychological Well-being of Health Care Workers During an Epidemic: A Thematic Review

Background: Health care workers (HCWs) constitute a vulnerable group in terms of physical, mental, and emotional health setbacks during an epidemic. An in-depth understanding of the effects of epidemics on HCWs is of utmost importance, in order to put in place measures for their well-being. The purpose of the review was to compile, compare, and contrast the available information so as to produce a lucid picture of how HCWs are impacted during an epidemic, and the factors that affect their mental health. Methods: A literature search of MEDLINE and Google Scholar databases was conducted to uncover research pertaining to four major epidemic outbreaks over the last two decades. The search was carried out at three levels using pertinent key words. The records thus identified were narrowed down at three further levels, that is, by screening of the title, abstract, and full text, to obtain articles most relevant to the subject matter. Data extraction was done using a spreadsheet to compile the relevant data. Data synthesis was done by studying those factors found to affect psychological well-being of HCWs and separating them into suitable sub-groups. Recommendations to mitigate the psychological impact were proposed. Results: Thirteen factors were identified, which were grouped under the broad categories of socio-demographic variables, individual characteristics, social characteristics, and psychological constructs. Conclusion: Epidemics have a profound impact on psychological well-being of HCWs. There is a pressing need to address the issue of the psychological health of this vulnerable group.
