Work-Related Musculoskeletal Disorders and Ergonomic Risk Profiles Among Surgical Intensive Care Nurses

Abstract

ABSTRACT Background: This study examined the relationship between ergonomic risk factors, postural behaviors, lifestyle habits, and the presence of work-related musculoskeletal disorders (WMSDs) among surgical intensive care nurses. Methods: This descriptive cross-sectional study included 227 surgical intensive care nurses in Türkiye. Data were collected using an online Nurse Assessment Form and analyzed using descriptive statistics, chi-square tests, and binary logistic regression analysis. Results: Most nurses reported inadequate sleep (64.4%) and irregular sleep patterns. The prevalence of WMSDs increased significantly with age and professional experience—from 18.1% among nurses ≤30 years to 54.5% among those ≥41 years (p<0.001). Nurses with WMSDs reported significantly lower use of correct body mechanics (25.5% vs. 46.5%; p=0.004) and lower physical activity levels (p=0.018). WMSDs were significantly more prevalent among nurses working in second-level ICUs compared with those working in third-level ICUs (44.8% vs. 21.2%; p=0.008). Binary logistic regression analysis identified age and correct use of body mechanics as significant predictors of WMSDs. Conclusion: Surgical intensive care nurses experience substantial ergonomic risk exposure that may contribute to the development of WMSDs. Continuous ergonomics training, improved shift scheduling, posture-supportive workplace practices, and the promotion of regular physical activity may help reduce musculoskeletal strain and improve occupational well-being. These findings highlight the importance of integrated ergonomic strategies to enhance nurse well-being and patient safety in surgical intensive care settings.
