Abstract
Nursing personnel are at a high risk from occupational low back injury. Work organization has been suggested as one factor playing a part in the aetiology of occupational low back pain. Baseline data for a prospective epidemiology study were gathered by means of a questionnaire. One part of the questionnaire elicited characteristics of work organization, perceived autonomy, the relationship with head nurse and satisfaction in the relationship with co-workers. Information on history of musculoskeletal problems, reported frequency of lifting and personal characteristics was also gathered. Of 787 nursing staff at two acute care hospitals, 154 (19-6%) reported troublesome low back pain occurring within the previous 6 months. From univariate analyses, such characteristics of work organization as shift, type of schedule and primary versus functional nursing were not associated with low back pain. The relationship with head nurse and perceived autonomy of the job also were not related to recent back pain. Recent low back pain was significantly associated with younger age, the job category ‘registered nurse’ and greater satisfaction in relationships with co-workers. These associations were confirmed in multivariate analysis. None of the work organization factors examined, with the exception of satisfaction with co-workers, were associated with back pain in this study. Moreover, the positive association of satisfaction with coworkers suggests that interventions to improve working relationships may not be helpful in prevention programmes. To some extent, these results are susceptible to biases resulting from selective attrition from nursing and selective participation in the study.
