Musculoskeletal disorders among Tunisian hospital staff: Prevalence and risk factors

Abstract

Aim of the workMusculoskeletal disorders (MSD) represent a significant occupational problem among hospital staff; however, data on musculoskeletal health of hospital staff are sparse. This study sought to determine the prevalence of MSD, their epidemiologic data and the associated risk factors. MethodsA previously self administered questionnaire sought information on demographics, prevalence and pattern of MSD, associated risk factors was employed as the survey instrument. A total of 520 questionnaires were distributed to hospital staff but only 433 questionnaires was valid. Eighty-seven of the returned questionnaires were excluded because of incomplete data. ResultsThe prevalence of MSD among hospital staff was 65.4%. Musculoskeletal disorders occurred mostly in low back (74.5%), neck (38.1%), and knees (31.1%).Factors associated to MSD were age (P<0.001), female gender (P<0.001), years of service (P<0.001) as well as prolonged standing or sitting (P=0.016 and 0.023, respectively). No significant association was found between repetitive movement, uncomfortable postures, heavy load handling, working on night shifts, stress and the presence of MSD. ConclusionA high proportion of hospital staff reported MSD at some body site with the low back being injured most often. Education programs on prevention and coping strategies for musculoskeletal disorders are recommended for hospital staff in order to reduce the rate of occupational hazards and also promote efficiency in patient care.
