Burnout in radiation therapists: Systematic review with meta-analysis

The main aim of this review is to evaluate the burnout levels experienced by radiation therapists. PubMed, Lilacs and Google Scholar were searched for articles reporting burnout levels in radiation therapists. Only studies explicitly assessing burnout and using a validated instrument were retrieved. Meta-analyses were undertaken, based on articles that used the Maslach Burnout Inventory to assess burnout, to determine 95% confidence intervals for the overall prevalence of radiation therapists with high burnout risk in three dimensions: emotional exhaustion, depersonalisation or low personal accomplishment. Additionally, meta-analyses were also performed to determine the overall mean reported for each of the three dimensions. A total of eleven studies were found to be eligible for inclusion in this systematic review, nine of which used the Maslach Burnout Inventory questionnaire. The 95% confidence intervals for radiation therapists with high emotional exhaustion scores, high depersonalisation scores and low personal accomplishment scores were [24.8; 54.6], [10.1; 40.2] and [17.4; 41.6] respectively. The 95% confidence intervals for the corresponding means were found to be [20.0; 26.2], [5.1; 8.8] and [35.9, 39.6] respectively. The meta-analysis revealed an arguably high prevalence of burnout in radiation therapists in spite of it varying substantially between studies.
