[Analysis of occupational burnout status and related factors among immunization program staff in Dezhou City, 2025]

Objective: To analyze the current status and related factors of occupational burnout among immunization program staff in Dezhou City in 2025. Methods: From February to March 2025, 1 209 healthcare workers engaged in immunization programs in all disease prevention and control centers (CDCs), vaccination clinics and obstetrics vaccination rooms within the jurisdiction of Dezhou City were enrolled in this study. Basic information was collected via questionnaires. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to assess occupational burnout status across three dimensions: emotional exhaustion, depersonalization and low personal achievement, with severity graded by scores. Multivariate logistic regression models were adopted to analyze the related factors of occupational burnout. Results: Among 1 209 participants, 986 (81.56%) were female and 513 (42.43%) were aged ≥40 years old. About 91 (7.53%) worked in CDCs, 970 (80.23%) in vaccination clinics and 148 (12.24%) in obstetric units. The detection rate of occupational burnout was 83.87% (1 014/1 209), with mild-to-moderate and severe occupational burnout rates of 16.38% (198/1 209) and 67.49% (816/1 209), respectively. Multivariate logistic regression model showed that compared with those who had no intention of resigning, those who frequently had turnover intention (OR=10.225, 95%CI: 4.093-25.543) had a higher risk of experiencing occupational burnout. Compared with those who slept for more than seven hours a day, those who slept for less than six hours a day (OR=4.266, 95%CI: 1.773-10.266) and those who slept for 6-7 hours (OR=1.543, 95%CI: 1.100-2.164) had a higher risk of developing occupational burnout. Conclusion: The detection rate of occupational burnout among immunization program staff in Dezhou City is relatively high, significantly related to frequent turnover intention and insufficient sleep.
