Ergonomic and psychosocial risk factors associated with work-related musculoskeletal disorders in Mohs histotechs

Mohs histotechs are at high risk for work-related musculoskeletal disorders (WRMSDs) due to repetitive motions, forceful exertions, and fixed postures required for their work. Psychosocial factors such as perceptions of pressure to achieve deadlines may exacerbate risk of occupational injury. To assess the prevalence of and risk factors for WRMSD in Mohs histotechs, an online survey was created using literature review, expert opinion, and two validated instruments (the Nordic Musculoskeletal Questionnaire and the Oldenburg Burnout Inventory) and distributed to Mohs histotechs. 88% of respondents reported musculoskeletal problems in 2 or more of the 9 body sites assessed in the past year. Standing during specimen processing was correlated with having neck pain and upper back pain, while sitting was protective against lower back pain. Individuals that felt that they could not take breaks or slow their pace of work were more likely to report pain at multiple body sites. Total pain scores were significantly lower in those reporting extensive ergonomic training. There is a high prevalence of WRMSD in Mohs histotechs. Addressing poor posture as well as psychosocial risk factors could further reduce injury.
