Puntos clave

This study aims to evaluate the prevalence of depression among emergency physicians in South Korea and identify associated factors.
Cross-sectional study design using data from the 2025 Korean Emergency Physician Survey.
Screening for depression was conducted using the PHQ-9 questionnaire.
Multivariable logistic regression analyzed factors associated with depression considering demographic and occupational variables.
Additional measures included the Korean Epworth Sleepiness Scale and Adult APGAR for wellness assessment.
14.9% of screened emergency physicians showed positive depressive symptoms.
Higher perceived burdens related to staffing and patient stressors were reported by depressed physicians.
Protective factors included being married, longer sleep duration, better sleep quality, and regular meal times.
Increased depression odds were linked to cancer history, current alcohol consumption, daytime sleepiness, and verbal abuse incidents.

Resumen

Background and Objectives: Emergency physicians practice in high-pressure environments and face occupational stressors that may affect their mental health. This study was designed to evaluate the prevalence of depression among emergency physicians in South Korea and examined environmental, sociolegal, and individual factors associated with depressive symptoms in the post-pandemic period. Materials and Methods: This nationwide cross-sectional study analyzed data from the 2025 Korean Emergency Physician Survey. Screening positive for depressive symptoms was defined as a Patient Health Questionnaire-9 (PHQ-9) score ≥ 10, indicating moderate-to-severe depressive symptom severity. Measures included the PHQ-9, the Korean Epworth Sleepiness Scale (KESS), and the Adult APGAR, a brief self-administered instrument assessing overall wellness. Multivariable logistic regression was performed to identify factors associated with depression after adjusting for demographic, clinical, and work-related variables. Results: Of the 1050 physicians who responded (response rate: 37.5%), 743 emergency physicians completed the PHQ-9 section (completion rate: 70.8%; mean age, 43.2 ± 7.78 years; 86.5% male), and 111 (14.9%) screened positive for depressive symptoms. Objective workload indicators, including total work hours and number of night shifts, did not differ between physicians with and without depression. However, emergency physicians screening positive for depression reported higher perceived burdens related to staffing shortages and patient-related stressors. Protective factors included being married (adjusted odds ratio AOR, 0.22; 95% confidence interval CI, 0.08–0.58), longer sleep duration (AOR, 0.65; 95% CI, 0.50–0.86), better sleep quality (AOR, 0.45; 95% CI, 0.27–0.74), fixed mealtimes (AOR, 0.60; 95% CI, 0.39–0.93), and higher Adult APGAR scores (AOR, 0.72; 95% CI, 0.60–0.86). Factors associated with increased odds of depression included a history of cancer (AOR, 14.63, 95% CI, 2.53–84.61), current alcohol consumption (AOR, 2.54, 95% CI, 1.14–5.68), daytime sleepiness (AOR, 1.17; 95% CI, 1.04–1.31), and more frequent verbal abuse during the previous 12 months (AOR, 1.25; 95% CI, 1.08–1.44). Conclusions: Depression was prevalent and was associated with perceived work burden, sleep health, lifestyle regularity, and psychosocial factors. Interventions should address sleep quality, workplace safety, and social support.
