Study population: The study will take place on the Navajo Reservation and within Navajo Area IHS clinical facilities. The Navajo Reservation covers over 27,000 square miles in rural New Mexico and Arizona. The proposed evaluation will occur at the six sites, including two which are currently implementing COPE as well as four sites which will implement COPE in the next two years. The health care centers included in this evaluation represent a mix of federally and tribally operated programs and together provide care for over 200,000 individuals. All sites use a common suite of software applications to record electronic health care data: the IHS RPMS (Resource Patient Management System).
Study Design: The research is aligned with PCORI's definition of patient-centered research by answering questions that will allow patients and other stakeholders to make informed health care decisions. This will be completed by incorporating patient input at all stages; comparatively assessing the benefits and weaknesses of COPE; capturing the "voice" of stakeholders through qualitative methods; choosing outcomes that have been cited as relevant to patients' own priorities and decision-making; and studying cross-site variation to capture individual and community factors associated with impact. The study will address the following questions:
1. Do clinical outcomes (hemoglobin A1c, blood pressure, cholesterol, and body mass index) improve more among COPE participants, compared with similar patients who do not participate in COPE?
2. Do COPE patients experience improvements in self-rated overall health, quality of life, empowerment and satisfaction compared with similar patients who do not participate in COPE?
3. As COPE is implemented in six different service units across the Navajo Nation, can we identify any factors among patients, CHRs, and hospitals that are "key ingredients" for COPE to be effective?
4. Does COPE benefit the health system and population served from diverse stakeholder perspectives including CHRs, providers, and the local health care delivery system?
