The systematic evaluation of any health topic is essential to excellent public health practice. Systematic reviews, evidence-based recommendations, and meta-analysis are playing an increasingly important role in decision making in health-related issues and for setting priorities for research. We hope this collection of scientific reviews will encourage researchers to make use of existing knowledge and address issues that will maximize the future progress of occupational injury prevention. These issues include requiring that new interventions be rigorously evaluated, using a multidisciplinary approach to conduct intervention research that addresses worker groups and hazards at high risk for injury, developing study designs that include controls and measurable outcomes, and publishing these data in the scientific literature. These are necessary steps if the promise of NORA to improve worker health and safety is to be realized.
