Burnout and Associated Factors among Thai Anesthesiology Residents

Objective: The study evaluates the prevalence of burnout and the associated risk factors among Thai anesthesiology residents. Materials and Methods: This cross-sectional study was conducted by an online questionnaire and sent 385 anesthesiology residents in Thailand. The questionnaire consisted of a consent form, personal information, potential risk factors of burnout, and the Thai version of the Copenhagen Burnout Inventory-Student Survey (CBI-SS). Results: A total of 248 respondents completed the questionnaire. The overall prevalence of burnout among Thai anesthesiology residents was 35.5%. Sleeping for 5-6 hours (odds ratio 3.68, 95% CI 1.40 to 9.68, p = 0.008), sleeping less than 5 hours (odds ratio 6.89, 95% CI 1.90 to 24.92, p = 0.003), along with dissatisfaction and the idea of discontinuation of training, were associated with higher burnout (odds ratio 8.38, 95% CI 3.65 to 19.25, p < 0.001 and odds ratio 3.11, 95% CI 1.57 to 6.18, p = 0.001, respectively). Compared to first-year residents, second-year residents exhibited a lower risk of burnout (odds ratio 0.32, 95% CI 0.134 to 0.76, p = 0.009) while no significant difference among third-year residents (odds ratio 0.54, p = 0.17, 95% CI 0.25-1.17). Conclusion: The prevalence of burnout among Thai anesthesiology residents was high. Sleeping less than 7 hours, experiencing dissatisfaction, and contemplating discontinuation of training were associated with a higher risk of burnout, while being a second-year resident lowered the risk.
