The Environmental Public Health Tracking Network (Tracking Network) is a national surveillance system that integrates environmental hazard, exposure, and health outcome data into one system. The Tracking Network launched in July 2009, and has since been receiving data from 23 funded state and local health departments, and several national partners. Despite this success, some challenges exist in obtaining more timely and complete data. This presentation will discuss how the Tracking Network is exploring the use of EHR to meet Tracking Network surveillance challenges and provide other opportunities to enhance environmental public health surveillance.
