Work-related musculoskeletal disorders in anesthesiologists: A cross-sectional study on prevalence and risk factors

Aim: To investigate the prevalence of self-reported work-related musculoskeletal disorders (WRMDs) of anesthesiologists, toevaluate potential risk factors, including personal and workload characteristics and working ergonomics.Material and Methods: A cross-sectional international survey including personal and workload characteristics of anesthesiologistswas conducted. The Standardized Nordic Musculoskeletal Questionnaire was used to identify working ergonomics and the qualityof ergonomic conditions of the operating room. The prevalence of WRMDs was calculated, and predictors of these symptoms wereevaluated using binary logistic regression.Results: 98.4% of respondents reported a WRMD in the previous 12 months, mainly low back disorders (70.7%). Cardiothoracicanesthesiologists were more likely to report 12-month knee problems (66%). Overall, pediatric anesthesiologists were more likely toreport 12-month WRMDs in most of their body sites. Women were more likely to develop WRMDs in the upper back (OR=2.465; 95%CI:1.061-5.729) as compared with men. Long-duration bending was the most significant ergonomic hazard for all 3 body regionsof musculoskeletal symptoms, with an OR of 4.210 (95% CI:1.081-16.391) for the neck, 4.619 (1.274-16.744) for the upper back,and 4.750 (1.045-21.590) for the low back. Suboptimal quality of ergonomic conditions in the operating room was significantlyassociated with increased WRMDs risk of the neck (OR=0.346; 95% CI:0.147- 0.812) and shoulder (OR=0.405; 95% CI:0.167- 0.982)regions.Conclusion: Anesthesiologists are at high risk for WRMDs. There is a need to improve ergonomic conditions of operative roomsaccording to demands of anesthesiologists and to educate them on proper posture for a longer and pain-free career.
