Purpose. To assess the prevalence and factors of burnout among Australian orthopaedic trainees. Methods. 236 orthopaedic registrars of the Australian Orthopaedic Association were invited to participate in a 32-item survey by email. The questionnaire assessed potential factors associated with burnout, satisfaction with the choice of orthopaedics as a career and work-life balance, and subjective overall health, as well as 3 subscales of the Maslach Burnout Inventory – Human Services Survey for assessing burnout: emotional exhaustion, depersonalisation, and personal accomplishment. Participants with high levels of either emotional exhaustion or depersonalisation were defined as having burnout. Those with and without burnout were compared. Results. 51 (22%) of the 236 trainees completed the questionnaire. Of whom, 88% were satisfied with their choice of orthopaedics as a career, whereas 27% were satisfied with their work-life balance. 27 (53%) respondents were considered burned out. Compared with those who did not burn out, those who burned out were less satisfied with their careers (p=0.004) and work-life balance (p=0.021). Conclusion. 53% of Australian orthopaedic trainees were burned out. Burnout trainees were more likely to be dissatisfied with their career choice and work-life balance. Active interventions to combat burnout and improve work-life balance are needed.
