 Obstructive sleep apnea OSA is estimated to be the third most common chronic disease in Veterans and is associated with an increased risk of hypertension, heart attacks, strokes, depression, and driving accidents. Current in-person management at a sleep center limits Veterans access to care, prolongs patient wait times, and requires Veterans living in remote areas to travel long distances. This proposal will evaluate an innovative web-based clinical pathway to diagnose and manage Veterans with OSA. In FY13, the investigative team received a VHA Innovation Award to create the Remote Veteran Apnea Management Portal REVAMP, a personalized, interactive website that, when combined with other emerging telehealth technologies, is designed to improve access to care, reduce patient wait times, and allow Veterans to receive care without travelling to a sleep center. Veterans complete intake and follow-up questionnaires on the REVAMP website and perform an unattended home sleep test HST without in-person instructions. Sleep specialists review the findings with the patient during an initial phone clinic. REVAMP auto-populates the Veterans questionnaire responses into templated progress notes that are exported to CPRS, the electronic medical record. Veterans diagnosed with OSA are treated with automatically adjusting positive airway pressure APAP units. These devices transmit data wirelessly to the website where treatment use and its effectiveness can be monitored by both Veterans and practitioners, thereby promoting patient self-management and productive patient-practitioner interactions.
