Research Highlights
For long-term and costly workers’ compensation claims, researchers identified four contexts in the return-to-work process that contributed to problems. The risk of a “toxic dose” resulted when problems occurred across the different contexts.

Issue Briefing
Although young males have typically had higher work-related injury rates than older ones, this trend has changed in some parts of Canada, where young men now have rates similar to those of older men. This Issue Briefing presents a detailed breakdown of workplace injury rates for men and women in three provinces over time, and suggests potential reasons for the trends.

Researchers have been looking at how unemployment affects mental health since the Great Depression of the 1930s, if not earlier. This body of research has shown that becoming unemployed has a negative impact on mental health. Also, people with mental health problems are more likely than others to become unemployed. This Issue Briefing summarizes the key research behind these findings and explores the implications for policy-makers and health and safety service providers.

Research is emerging that “newness” is associated with a higher risk of work injury. Whether it’s young workers, workers of all ages new to their jobs, recent immigrants or employees in newly established firms, the evidence indicates that these workers face higher injury rates and/or more hazardous jobs. This Issue Briefing summarizes the key research behind these findings and explores the implications for policy-makers and health and safety service providers.

Issue Briefing
A worldwide recession has begun in the wake of the Fall 2008 meltdown of financial markets. What is the likely impact of the recession on workers’ compensation costs? Are work-related injuries likely to be more severe? What can we anticipate about claim frequency and severity when recovery occurs and economic growth resumes? This Issue Briefing explores findings from past research on workers’ compensation and the business cycle from IWH and other sources.

Injuries to the upper extremity are common among workers, accounting for about 30 per cent of lost-time claims in Ontario in 2006. The upper extremity includes the neck, shoulder, upper arm, elbow, forearm, wrist and hand. This systematic review looked at the effectiveness of interventions to prevent upper extremity disorders and traumatic injuries.

In 2004, Washington State enacted a three-year pilot program enabling nurse practitioners to work in an expanded role as “attending providers” for injured workers. Following an evaluation, the program was made permanent. This case-study-based research showed how involving stakeholders enhanced the impact of research on health policy.

Workplace factors (such as firm size and union status) have greater influence than individual factors (such as health) on the likelihood that an injured worker will be offered and will accept modified work. The findings suggest more attention needs to be paid to workplace factors early in the return-to-work process.

Injury/illness prevention and loss control programs (IPCs) help protect workers from injuries, meet regulatory requirements, reduce the negative effects of injuries and manage costs. IPCs include the three Ps: work practices among employees, policies developed by employers and programs required by legislation. This systematic review has shown that there is strong evidence supporting the effectiveness of disability management/return-to-work programs.

Systematic Review

Small businesses have unique challenges with occupational health and safety (OHS). Overall, workers in small business have a higher risk of injury than workers in large firms, yet small-business owners and their workers may not have a sense of this increased risk because a work injury in any one small workplace is relatively rare. This reports shares the findings of a systematic review conducted to provide an understanding of, and guidance on, how to implement OHS in small businesses and what OHS programs are most likely to work.
