“…In the pooled random-effect estimates of prevalence in these 21 studies, 32% (95% CI, 27%-38%; I 2 = 95.32%; P < .001) of physicians and dentists exceeded the high threshold for emotional exhaustion, and 25% (95% CI, 18%-32%; I 2 = 98.20%; P < .001) were above the high threshold for depersonalization (Figure 2). [39][40][41][42]44,45,48,50,53,54,80,[84][85][86][87][88][89][90][91][92][93][94] In 20 studies, 33% (95% CI 22%-45%; I 2 = 99.25%; P < .001) were below the low threshold for personal accomplishment (eAppendix 4 in the Supplement). Subgroup analyses suggested that the prevalence of burnout dimensions varied depending on the country's geographical region (P for heterogeneity < .001), physician specialties (P for heterogeneity < .001), and thresholds used (emotional exhaustion and personal accomplishment: P for heterogeneity = .007; depersonalization: P for heterogeneity < .001).…”
