Prevalence of Burnout in Healthcare Specialties: A Systematic Review Using Copenhagen and Maslach Burnout Inventories

BACKGROUND This systematic review used the Copenhagen (CBI) and the Maslach (MBI) Burnout Inventories and its scales to assess and compare studies that involved students and workers in all medical specialties. MATERIAL AND METHODS PubMed, ScienceDirect, Scopus, Wiley Library, and Web of Science databases were searched using keywords and Medical Subject Headings. Identified studies were in English, published between 2008 and 2022, measured the burnout of healthcare workers and students by using CBI and MBI, and observed adverse patient outcomes. RESULTS A total of 38 studies were included in the current review. All included studies assessed and evaluated subjects and participants by observing clinical measures, personal and demographic data, countries where the study was conducted, and study type used. Fifty percent of CBI papers were conducted in Saudi Arabia and other Arab countries, whereas the majority of MBI papers (10) were conducted in Europe, followed by 9 studies conducted in Saudi Arabia and other Arab countries and 6 studies conducted in the USA and Canada. The overall percentage of burnout in CBI studies (53%) was higher than that in MBI studies (35%). Also, the types and domains in CBI were marginally higher than those in MBI. CONCLUSIONS Studies that used CBI scales recorded higher burnout compared with studies that used MBI. Females, higher education levels, and marriage status of the tested subjects showed higher CBI and MBI scale scores in comparison to their counterparts. Higher significant differences percentages in burnout types and genders were recorded in CBI than in MBI.
