Burnout syndrome in Brazil (2014-2024): regional variations and temporal trends in an epidemiological study.

Introduction: Burnout syndrome is classified in International Classification of Diseases-11 as a disorder related to chronic workplace stress, characterized by emotional exhaustion, negative feelings toward work, and reduced professional efficacy. It represents a growing public health issue impacting quality of life and productivity.

Objectives: To analyze the regional and temporal distribution of burnout syndrome in Brazil between 2014 and 2024, based on sociodemographic and clinical data available in the public health system.

Methods: A retrospective, observational, quantitative study using data extracted from the Departamento de Informática do Sistema Único de Saúde system. Variables analyzed included sex, age group, race, substance use, psychotropic drug use, treatment regimen, referral to Psychosocial Care Centers, and clinical evolution. Statistical analysis was performed using Microsoft Excel 2013 with analysis of variance, 95%CI, and p < 0.05 as significance threshold.

Results: Most reported cases were women (71.6%), aged 35 to 49 years (56.7%). The Southeast (52.8%) and Northeast (29.8%) regions concentrated most notifications. The year 2024 had the highest notification rate (28.4%; p = 0.008). Psychotropic drug use was identified in 51.7% of cases, while alcohol, tobacco, and illicit drug use accounted for less than 8%, without statistical significance. Conclusions: The syndrome showed a 96.4% increase over the analyzed period, predominantly affecting women in the Southeast region. This rise may be related to increased diagnostic awareness, professional training, and mental health awareness strategies.
