Prevalence and work-related factors associated with burnout among healthcare workers in Kamina, Democratic Republic of Congo

Background Burnout is a major occupational health issue affecting healthcare workers worldwide, particularly in low-resource settings where working conditions are often demanding. This study aimed to determine the prevalence of burnout and identify work-related factors associated with burnout among healthcare workers in Kamina, Democratic Republic of Congo. Methods A cross-sectional analytical study was conducted among 509 healthcare workers using a convenience sampling approach. Data were collected through a structured questionnaire incorporating items adapted from the Maslach Burnout Inventory. Burnout was defined as a dichotomous outcome (yes/no). Independent variables included sociodemographic and work-related characteristics based on the demand–control–support model. Bivariate and multivariate logistic regression analyses were performed to identify independent predictors of burnout. Results The prevalence of burnout was 45.3%. Multivariate analysis identified three independent predictors of burnout: more than five years in service (adjusted OR = 1.89; 95% CI: 1.24–2.89; p = 0.003), working in health centers compared to hospitals (adjusted OR = 1.69; 95% CI: 1.17–2.45; p = 0.005), and having an imposed work schedule (adjusted OR = 2.55; 95% CI: 1.11–5.85; p = 0.027). No significant associations were observed with sociodemographic variables. Conclusion Burnout is highly prevalent among healthcare workers in Kamina and is significantly associated with modifiable work-related factors, particularly those related to work organization and job control. Strengthening working conditions and organizational support is essential to mitigate burnout and enhance health system performance.
