The global prevalence of burnout among general practitioners: a systematic review and meta-analysis

Background Burnout among general practitioners (GPs) has attracted the attention of more and more researchers. An adequate understanding the prevalence and related factors of burnout to prevent and reduce burnout is necessary. This study systematically measured the global prevalence of burnout among GPs. Methods Eligible original studies were identified from the PubMed, Ovid Embase, Ovid Medline (R), and Web of science databases. We searched the full-time period available for each database, up to 30 September 2021. The adjusted prevalence rate was estimated using a random-effects meta-analysis. The heterogeneity was evaluated using I-2 statistic. Differences by study-level characteristics were estimated via subgroup analyses and meta-regression. Results A total of 16 cross-sectional studies with 7,595 participants were included. The pooled burnout rate showed 37%, 28%, and 26% of general GPs suffer from high emotional exhaustion (EE), high depersonalization (DP), and low personal exhaustion (PA), respectively. Groups comparisons found that high EE, high DP, and low PA rate data obtained from 2001 to 2009, high DP rate data obtained from Europe, low PA rate data obtained from high-quality studies had much higher rates. Conclusions This study demonstrated the prevalence of burnout in the GPs and alert health managers to tailor their strategies to retain this community. Targeted initiatives are needed to provide adequate GPs' well-being and maintain primary health care.
