Promoting the Use of CPAP Therapy Among OSA Patients

Study Overview
=================
Brief Summary
-----------------
Obstructive sleep apnea (OSA) is the most common sleep breathing disorder in the U.S. Continuous Positive Airway Pressure (CPAP) therapy is the most effective treatment for OSA. However, up to 50% of patients who accept using CPAP therapy fail to adhere to it. This study will evaluate an information systems (IS)-based solution that sends tailored, motivational, educational messages and tailored feedback messages to promote CPAP usage among noncompliant OSA patients. The primary aim of this study is to determine the efficacy of the proposed IS solution and its effect on fostering the use of CPAP therapy among OSA patients.

| Experimental: CPAP4HealthySleep: System 1 (ABAB)<br>Participants in this group will first receive six tailored educational messages per week and weekly feedback messages notifying participants of their CPAP usage on the seventh day for two weeks (type A). Next, they will receive weekly feedback messages only (one message per week) notifying participants of their CPAP usage for two weeks (type B), re-introduction of type A for another two weeks, followed by re-introduction of type B for two weeks. | Behavioral: CPAP4HealthySleep system<br>* Tailored multimedia messages and tailored feedback messages delivered via web-based system to participants' phones to motivate them to use their CPAP therapy<br>|
