REVAMP consists of a Patient Platform and a Provider Platform. In the Patient Platform, veterans with sleep apnea will confirm their demographic information, answer questionnaires regarding sleep health, review the treatment data from their PAP devices graphically, correspond with providers, and have access to educational material about their condition. In the Provider Platform, sleep clinicians will set up patient accounts, schedule patients for sleep testing and enter their results, review patient PAP data, assign questionnaires, schedule appointments, write Progress Notes, and correspond with patients. Authorized provider users will also have the ability to manage the educational material and automated messages for patients.
