Summary
This study found no significant cost savings or effectiveness for a worksite low back pain (LBP) prevention program. The program did not demonstrate benefits for workers in physically demanding jobs.
Area of Science:
- Occupational health
- Public health
- Health economics
Background:
- Low back pain (LBP) imposes substantial economic burdens in Western societies.
- Limited data exists on the effectiveness, costs, and savings associated with LBP prevention programs in occupational settings.
Purpose of the Study:
- To assess the effectiveness and economic impact of an occupational low back pain prevention program.
- To provide evidence for the adoption of worksite interventions for LBP.
Main Methods:
- A cluster randomized controlled trial with economic evaluation was conducted.
- The study involved 18 clusters (work units) from 9 Dutch companies, randomizing 258 workers to an intervention group and 231 to a control group.
- A 12-month follow-up period was used to collect data.
Main Results:
- No significant differences in effectiveness or cost savings were observed between the intervention and control groups.
- Indirect costs, including work absence and productivity losses, constituted the majority (84%) of total LBP-related expenses.
Conclusions:
- The evaluated worksite prevention program for low back pain lacks evidence for adoption.
- Further research may be needed to identify effective and cost-efficient LBP prevention strategies in occupational settings.
