Individual and organizational interventions to reduce burnout in resident physicians: a systematic review and...

Burnout among resident physicians during training has been prevalent, prompting training centers to introduce interventions at the individual or organizational level. However, empirical evidence is crucial before implementing such programs in practice.

A systematic review and meta-analysis was carried out to evaluate the effectiveness of individual and organizational interventions in reducing burnout among resident physicians. Searching was done across five databases-PubMed, Scopus, ScienceDirect, Embase, and Cochrane Library from 1 December 2023 to 26 August 2024. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used for our reporting of study selection process. Eligibility criteria were randomized or non-randomized designs, with prospective intervention, with a comparator group focused on individual or organizational interventions reducing burnout, in any language and publication date. The Maslach Burnout Inventory scores for emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA) were the three outcome measures. Two investigators independently extracted the data. The risk of bias was evaluated using Cochrane risk-of-bias tool for randomized trials (RoB2) and non-randomized studies of interventions (ROBINS-I). Cohen's d and heterogeneity was estimated using a random-effects DerSimonian-Laird model and visualized by forest plots. Sensitivity analyses were carried out by leave-one-out meta-analysis.

We identified 33 eligible studies (n = 2536), comprising 25 (75.8%) individual intervention studies and 8 (24.2%) organizational intervention studies. Cohen's d for individual intervention versus control were as follows: EE -0.25 (95% CI -0.40 to -0.11, p < 0.01, I² = 49.3%), and DP -0.17 (95% CI -0.32 to -0.03, p = 0.02, I² = 50.0%). The organizational intervention showed no significant association with any domain. Sensitivity analyses were robust in all outcomes, with differences in intervention description and design identified as potential contributors to heterogeneity.

Various interventions, including individual coaching, meditation, and organization interventions, have been implemented to improve resident burnout. The effectiveness of intervention demonstrated none to small practical significance in improving burnout. Data inconsistency and high risk of bias across studies limited the validity of the pooled results. Further studies should focus on a combined approach.
