Burnout and allostatic load among health workers engaged in human resourced-constrained hospitals in Accra, Ghana.

Background: Burnout syndrome is a psycho-social disorder which develops in an individual exposed to chronic stress on the job. Health workers in sub-Saharan Africa (SSA) are at increased risk of burnout due to job-related challenges. Burnout does not only affect the job performance of employees, but could result in dysregulation of multiple physiological systems (allostatic load) in victims and predispose them to non-communicable diseases (NCDs). This study examined the association between burnout and allostatic load among health workers engaged in human resourced-constrained hospitals in Accra, Ghana.

Method: This study was a hospital-based cross-sectional study involving 1264 health workers (clinicians and non-clinicians) from three public hospitals in Accra, Ghana who were recruited using a proportionate stratified random sampling technique. The participants completed a questionnaire which collected general and burnout information. In addition, each participant's anthropometric; biochemical and hemodynamic indices were measured. The allostatic load in the participants was determined using eleven (11) biomarkers from the neuro-endocrine, cardiovascular, metabolic and anthropometric measures. The relationship between burnout and allostatic overload (high allostatic load) was determined at the bivariate and multivariable levels. The data analysis was done with the aid of Stata 15.0 at a 95% confidence level.

Results: The prevalence of burnout was 20.57%, higher in non-clinicians than clinicians (26.74% vs 15.64, p <  0.001). Also, non-clinical participants had higher levels of emotional exhaustion and depersonalization than the clinical participants. Over a quarter (26.27%) of the participants had allostatic overload manifesting as high allostatic load. Furthermore, for a one unit increase in overall burnout, the odds of experiencing allostatic overload was increased by 17.59 times (AOR = 17.59, 95% CI: 11.7-26.4) as compared to those without burnout and similar findings were found for the individual components of burnout syndrome with high allostatic load.

Conclusion: Burnout among health workers is associated with multi-system physiological dysregulation manifesting as high allostatic load; a major risk factor for NCDs. It is recommended that measures aimed at reducing burnout and allostatic overload such as structured psychological counseling and healthy lifestyle patterns are recommended for health workers engaged in stressful work settings to reduce their risk of NCDs.
