The new national emphasis on comparative effectiveness research is likely to generate an unprecedented volume of new findings. It is essential to anticipate the obstacles that front-line health care professionals will face in translating these results into better clinical decision making. We review the current barriers to the dissemination of evidence-based clinical recommendations, including problems with continuing medical education, provider incentives, and quality assurance. We then propose solutions, including more effective educational outreach programs, requirements for practitioners to master important findings, and alignment of incentives to encourage evidence-based practice. Such strategies can lead to policies that could encourage the uptake of new comparative effectiveness data and encourage their translation into better clinical practice.T he industrialized world has focused intensely in recent decades on applying advances in basic biomedical research to the production of new drugs and devices. However, this "bench to bedside" translation has not been matched by comparable attention to using that research to change what physicians actually dowhat might be called the "bench to behavior" translation. A major gap persists between the best available information on therapeutic effectiveness and safety, on the one hand, and typical patterns of care, on the other.1,2 Problems in translating into practice the conclusions of several major comparative effectiveness research trials, as discussed below, show that studies may be rigorously designed and carried out, producing important clinical findings, yet remain poorly applied in typical practice settings.
Emergence Of New Research FindingsAs a result of recent changes in federal law, new funding, and the creation of the new PatientCentered Outcomes Research Institute, the United States is now gearing up to produce an unprecedented volume of new research evaluating comparable therapeutic interventions. It is critical to understand the barriers that exist between generating these comparative effectiveness findings and changing practice by front-line physicians and other health professionals-and to develop strategies to overcome these obstacles.
3Delaying the adoption of research findingsor refusing to adopt them-is not a novel problem in medicine. In the mid-nineteenth century, Ignác Semmelweis in Europe and Oliver Wendell Holmes Sr. in the United States employed observational and then interventional "comparative effectiveness" studies to demonstrate that hand washing by health professionals before they delivered babies was associated with a marked reduction in maternal death from puerperal fever, a serious bacterial infection that can affect mothers after childbirth. Yet it took the medical profession years to incorporate these life-saving
