Clinical Practice & Policy: Navigation Guide

An Evidence-Based Medicine Methodology to Bridge the Gap Between Clinical and Environmental Health Sciences

The scientific evidence linking environmental exposures to adverse health outcomes has yet to be compiled using systematic methods with the capacity to inform effective healthcare and policy decision-making. The relevant evidence is largely unfamiliar to health professionals caring for women and men of childbearing age, patients, communities, consumers, and other impacted populations. There is currently no trusted reference or compendium that provides them with timely, evidence-based advice about exposure to environmental contaminants.

To bridge the gap between clinical and environmental health sciences, PRHE has undertaken an interdisciplinary collaboration to develop a systematic and transparent methodology to evaluate the quality of evidence and strength of recommendations about the relationship between the environment and reproductive health. The result of this collaboration---the Navigation Guide--- was published in the May 2011 issue of the journal Health Affairs. View the paper here: http://content.healthaffairs.org/content/30/5/931.full.pdf+html?ijkey=z58MCEPW2X49.&keytype=ref&siteid=healthaff. (Please note: This link requires a subscription.

Application of the Navigation Guide will result in uniform, simple, and transparent summaries that integrate the best practices of evaluation in environmental and clinical health sciences.
