Early return-to-work policy in many jurisdictions is underpinned by the "hurt" versus "harm" concept — that the pain a worker experiences after an injury does not cause harm or inhibit recovery. But there are situations in which this concept does not apply.

In participatory ergonomics (PE), a team works together to identify risks, and change tools, equipment and work processes to improve workplace conditions. PE programs can reduce work-related injuries to muscles, tendons, ligaments and other soft tissues. This systematic review identifies the factors that can increase the likelihood of a successful PE program in workplaces.

In participatory ergonomics (PE), a team works together to identify risks and change tools, equipment and work processes to improve workplace conditions. PE interventions have been shown to reduce work-related injuries to muscles, tendons, ligaments and other soft tissues. What elements of a participatory ergonomic intervention can help ensure its success in workplaces? This systematic review report answers this important question.

Injury/illness prevention and loss control programs help protect workers from injuries, meet regulatory requirements, reduce the negative effects of injuries and manage costs. An IWH systematic review on these programs found strong evidence supporting the effectiveness of disability management/return-to-work programs.

Systematic Review

Before employers invest in workplace health and safety interventions, they want to know the financial implications of their investment. The goal of this review was to explore whether such interventions are worthwhile from an economic point of view. To find an answer, the Institute for Work & Health conducted a systematic review of studies of workplace-based health and safety interventions that also had an economic analysis. This review, as outlined in this final report, sought to answer the following question: What is the credible evidence that incremental investment in health and safety is worth undertaking?
