Webinar 5: From Evidence to Action: Synthesizing Air Quality Evidence Relevant to Public Health

May 04, 2021 – 10:00am ET

Chairs: Neil Pearce, London School of Hygiene and Tropical Medicine, HEI Research Committee, and Jennifer Peel, Colorado State University, HEI Review Committee

Synthesizing evidence relevant to public health is now more important than ever. Evidence synthesis may include systematic reviews or formal meta-analyses of the findings of observational studies. There have been evolving approaches to synthesis and integration of various forms of evidence throughout the years, for example, the weight of evidence’s approach that the US EPA use in their integrated science assessments. Another approach is Grading of Recommendations Assessment, Development and Evaluation (GRADE), which has its origins in clinical research and has been adopted by the WHO and Cochrane Collaboration. It has been applied recently to assess the quality of evidence for environmental exposures, such as air pollution. However, GRADE considers results from randomized studies as higher-quality evidence than non-randomized designs, a criterion that creates difficulties in environmental research, where randomized designs are largely not possible, thus down-grading important evidence by default. Alternative promising strategies for evidence synthesis have been suggested, including “triangulation”. This session will examine approaches for evidence synthesis in environmental epidemiology and discuss possible paths forward.
