Evaluation of an educational low back pain prevention program for hospital employees.
OBJECTIVE
To evaluate the impact of an educational low back pain prevention program in a cohort of hospital employees.


METHODS
A cohort of 136 nonclerical hospital employees attended classes on safe postures and patient handling, then received advice by educators who observed them while they performed their typical workday tasks. Each of the subjects in this intervention group was matched on age, sex, and job category with a control. Musculoskeletal complaints and changes in habits during work and recreational activities were evaluated before the intervention (or the corresponding date in the control group) and after two years.


RESULTS
In the intervention group, 36% of subjects with low back pain at baseline were free of this symptom at follow-up, whereas only 26% were in the opposite situation. The proportion of subjects with low back pain episodes lasting longer than 30 days increased significantly from baseline to follow-up in the control group (from 30% to 49%) but not in the intervention group. The number of sick leaves longer than 30 days decreased significantly in the intervention group. Only 33% of the intervention group subjects felt the intervention had been helpful; this proportion varied across job categories.


CONCLUSIONS
Our data suggest that differences in job categories should be taken into account when designing educational programs for preventing low back pain. They also indicate that back school programs may be more effective in subjects with a history of low back pain, whereas instruction on safe postures and patient handling may be the best approach in subjects who have not previously experienced low back pain. Observing and providing advice to employees while they are performing their usual duties may be an essential component of low back pain prevention.
