Controlled interventions to reduce burnout in physicians a systematic review and meta-analysis

IMPORTANCE Burnout is prevalent in physicians and can have a negative influence on performance, career continuation, and patient care. Existing evidence does not allow clear recommendations for the management of burnout in physicians. OBJECTIVE To evaluate the effectiveness of interventions to reduce burnout in physicians and whether different types of interventions (physician-directed or organization-directed interventions), physician characteristics (length of experience), and health care setting characteristics (primary or secondary care) were associated with improved effects. DATA SOURCES MEDLINE, Embase, PsycINFO, CINAHL, and Cochrane Register of Controlled Trials were searched from inception to May 31, 2016. The reference lists of eligible studies and other relevant systematic reviews were hand searched. STUDY SELECTION Randomized clinical trials and controlled before-after studies of interventions targeting burnout in physicians. DATA EXTRACTION AND SYNTHESIS Two independent reviewers extracted data and assessed the risk of bias. The main meta-analysis was followed by a number of prespecified subgroup and sensitivity analyses. All analyses were performed using random-effects models and heterogeneity was quantified. MAIN OUTCOMES AND MEASURES The core outcomewas burnout scores focused on emotional exhaustion, reported as standardized mean differences and their 95confidence intervals. RESULTS Twenty independent comparisons from 19 studieswere included in the meta-analysis (n = 1550 physicians; mean SD age, 40.3 9.5 years; 49%male). Interventionswere associated with small significant reductions in burnout (standardized mean difference SMD = ?0.29; 95%CI, ?0.42 to ?0.16; equal to a drop of 3 points on the emotional exhaustion domain of the Maslach Burnout Inventory above change in the controls). Subgroup analyses suggested significantly improved effects for organization-directed interventions (SMD = ?0.45; 95%CI, ?0.62 to ?0.28) compared with physician-directed interventions (SMD = ?0.18; 95%CI, ?0.32 to ?0.03). Interventions delivered in experienced physicians and in primary care were associated with higher effects compared with interventions delivered in inexperienced physicians and in secondary care, but these differences were not significant. The results were not influenced by the risk of bias ratings. CONCLUSIONS AND RELEVANCE Evidence from this meta-analysis suggests that recent intervention programs for burnout in physicians were associated with small benefits that may be boosted by adoption of organization-directed approaches. This finding provides support for the view that burnout is a problem of the whole health care organization, rather than individuals.
