The New Mexico Community Health Assessment Program (CHAP) is a collaborative effort among the New Mexico Department of Health, county and tribal health councils, the University of New Mexico, and others. The goal of CHAP is to improve access to, and the quality of, public health data while simultaneously strengthening assessment capacity. CHAP has adopted a Web-based data query system originally developed in Utah. Consequently, New Mexico was able to quickly and efficiently establish a data dissemination system. New Mexico worked with tribal councils to strengthen community health assessment and develop comprehensive community health profiles, and with the New Mexico National Electronic Disease Surveillance System steering committee to include tribal affiliation and residence fields.
