RO1: Comparative Outcomes Management With Electronic Data Technology (COMET) Study

STAGE I of the COMET study is to develop an Electronic Network Informatics Infrastructure that will prospectively enable access to and the sharing of clinical and research data. STAGE II: This is a Comparative Effectiveness Trial (CET) evaluating positive airway pressure (PAP) vs. oral appliance (OA) therapy in improving hypertension and abnormalities in cardiovascular function in overweight/obese patients with obstructive sleep apnea (OSA). Data collected during the STAGE II study will be incorporated in Part 3 of the STAGE I study. STAGE III of the COMET study is completion of data analysis and preparation of the electronic network informatics infrastructure for use beyond the four Clinical Centers to interested CTSA institutions. We will also explore expanding ontologies, and the use of federated database methodology.
