Is Exhaustion More Sensitive Than Disengagement to Burnout in Academic Anesthesia? A Study Using the Oldenburg Burnout Inventory.

Reportedly, clinicians of all kinds are experiencing alarming rates of burnout, and its prevalence among anesthesia providers is high. We examined burnout in a large academic anesthesia department with a commonly used questionnaire, the Oldenburg Burnout Inventory, which provides scores on two scales, "exhaustion" and "disengagement." We examined differences in scores between exhaustion and disengagement and their prevalences. All N = 415 staff members of the department were requested to complete the Oldenburg Burnout Inventory and N = 130 (31%) did so. The mean ± standard deviation was 2.52 ± 0.51 (range, 1.13 to 3.75) for exhaustion and 2.27 ± 0.52 (range, 1.13 to 3.63) for disengagement. The mean for exhaustion exceeded that for disengagement by 0.25 ± 0.42 (range, -1.25 to 1.25), t(129)=6.68, p < 0.0001 by paired t test. Mean ratings exceeded the midpoint (2.5) between the "burned out" and "not burned out" ends of the rating scale for 49% of respondents for exhaustion, but only 30% for disengagement. More respondents (N = 87, 67%) had a higher mean for exhaustion than disengagement than the opposite pattern (N = 28, 22%), M = 29.5, p < 0.0001 by sign test. Thus, burnout symptoms were common but reflected more in exhaustion than disengagement. Literature review suggested that the difference between the exhaustion and disengagement means that we found was larger than typical, but not unusual, for health-care-related groups, and typical for other groups. Future studies should clarify circumstances under which exhaustion exceeds disengagement and vice versa, both in anesthesia and other fields.
