Grading quality of evidence and strength of recommendations.

Users of clinical practice guidelines and other recommendations need to know how much confidence they can place in the recommendations. Systematic and explicit methods of making judgments can reduce errors and improve communication. We have developed a system for grading the quality of evidence and the strength of recommendations that can be applied across a wide range of interventions and contexts. In this article we present a summary of our approach from the perspective of a guideline user. Judgments about the strength of a recommendation require consideration of the balance between benefits and harms, the quality of the evidence, translation of the evidence into specific circumstances, and the certainty of the baseline risk. It is also important to consider costs (resource utilisation) before making a recommendation. Inconsistencies among systems for grading the quality of evidence and the strength of recommendations reduce their potential to facilitate critical appraisal and improve communication of these judgments. Our system for guiding these complex judgments balances the need for simplicity with the need for full and transparent consideration of all important issues.

Developing and using the Guide to Community Preventive Services: lessons learned about evidence-based public health.

The Guide to Community Preventive Services (Community Guide) is being developed under the leadership of the independent, nonfederal Task Force on Community Preventive Services. The Task Force makes recommendations for the use of public health programs and policies based on scientific evidence about what practices have worked to improve health. The Community Guide thoroughly searches scientific literature for topic-relevant studies, evaluates their quality according to established criteria, and makes recommendations based on the overall strength of the body of evidence and the size and variability of reported effects. In addition, the Community Guide identifies promising interventions that have not been adequately researched, thus helping to inform the public health research agenda. The continuously updated and expanded body of recommendations and research agenda formulated by this rigorous process have been published on the Internet and in various publications since 1999 and constitute a highly valued and objective evidence-based resource for guiding current and future public health activities. More remains to be learned, however, on how best to disseminate Community Guide findings to key target audiences and encourage their use to inform practice, policy, and additional research.

Law as a tool for preventing chronic diseases: expanding the range of effective public health strategies.

Law, which is a fundamental element of effective public health policy and practice, played a crucial role in many of public health's greatest achievements of the 20th century. Still, conceptual legal frameworks for the systematic application of law to chronic disease prevention and control have not been fully recognized and used to address public health needs. Development and implementation of legal frameworks could broaden the range of effective public health strategies and provide valuable tools for the public health workforce, especially for state and local health department program managers and state and national policy makers. In an effort to expand the range of effective public health interventions, the Centers for Disease Control and Prevention will work with its partners to explore the development of systematic legal frameworks as a tool for preventing chronic diseases and addressing the growing epidemic of obesity, heart disease, stroke, and other chronic diseases and their risk factors.
