Physical work load and its assessment among the nursing staff in nursing homes.

A study was conducted to investigate the physical work load and the prevalence of musculoskeletal complaints of nurses in nursing homes. Thirty-six female subjects selected from three nursing homes in the Netherlands participated in an observational study. In addition, the total nursing staff (n = 668) was invited to take part in a questionnaire survey (response was 94%). It was noticed that almost 60% of the observed time was spent on nonpatient-related activities. Moreover, activities alternated rapidly and seldom lasted longer than 4 minutes on average. Twenty percent of the observed time was spent in "poor" work postures as defined by the Ovako Working Posture Analyzing System (Action Category 2 to 4). Activities contributing most to these poor work postures were patient care and household and preliminary tasks. Perceived exertion as scored on the Borg-CR10 scale was highest during patient-related activities. This holds also for a relative increase of heart rate. Questionnaire results showed prevalences of 41%, 35%, and 20% respectively, for back, arm/neck, and leg complaints. From this study it can be concluded that not only patient-related activities should be taken into consideration for the improvement of work postures and other potential strenuous aspects of nursing work. Household and preliminary tasks, ergonomic layout of the ward, and work pressure also deserve attention.
