简要总结
Although obstructive sleep apnea, a breathing disorder during sleep, is prevalent and recognized as a major public health concern, most Veterans with this disorder are undiagnosed and therefore untreated. Access to sleep laboratories for testing is limited particularly for those Veterans living in rural areas and Veterans with disabilities that prevent travel to a sleep center. The goal of this study is to compare a web-based telehealth management strategy to in-person management. The telehealth pathway will enable Veterans to be diagnosed and treated without visiting a sleep center. The investigators believe that telehealth management will increase Veterans' access to this specialized care at a cost that is less than in-person delivery but with similar improvements in daytime function.
详细描述
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 Fiscal Year 13, the investigative team received a Veterans Health Administration (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 Veteran's 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.
The investigators' proposed prospective, randomized intervention will compare the clinical and cost-effectiveness of REVAMP management of Veterans with OSA to in-person care. Aim 1 will determine if management with REVAMP is clinically non-inferior to in-person care in terms of improvement in functional outcomes and APAP adherence. Non-inferiority of clinical effectiveness following 3 months of APAP treatment will be expressed in terms of improvement in the score of the Functional Outcomes of Sleep Questionnaire (FOSQ-10), the investigators' primary outcome measure. Adherence to APAP will be objectively monitored by wireless transmission of data from the participant's home unit. In Aim 2, patient preference, medical service use and cost will be collected every 3 months for the entire observation period to compare cost effectiveness of the two managements. Preference will be assessed by the Short Form-6D (SF 6D), and the EuroQol-5D (EQ-5D). Differences in the ratio of cost and quality-adjusted life years saved by REVAMP compared to in-person management will test the hypothesis that REVAMP management will have lower cost and equivalent outcomes. The results of Aims 1 and 2 will provide evidence to support widespread dissemination of REVAMP. Formative evaluation in Aim 3 will use qualitative (targeted phone interviews) and quantitative measures (attrition, work alliance, and patient satisfaction) to inform clinicians, administrators and other stakeholders how to implement this innovative chronic disease pathway.
Aim 1 (primary). To compare functional outcomes following 3 months of APAP treatment in Veterans with OSA randomized to REVAMP versus in-person management. The primary outcome measure in this modified intent-to-treat analysis (i.e., subjects initiated on APAP with at least one FOSQ follow-up score) will be the change from baseline in the FOSQ-10 score. Analysis will also compare the mean daily hours of APAP use in participants in the two groups initiated on APAP treatment.
Hypothesis 1a: Mean change in FOSQ-10 score among participants randomized to REVAMP management will be no more than one point less than that in participants receiving in-person management.
Hypothesis 1b: Mean daily hours of APAP use among participants receiving REVAMP management will be no more than 0.75 hour less than that in participants randomized to in-person management.

结局指标
主要结局
Functional Outcome of Sleep Questionnaire - Short Form (FOSQ-10)
时间窗: 3 months
FOSQ-10 score ranges between 5 and 20 units; there is not threshold for normality; a higher score indicates higher functional outcome. Outcome Measure: Change from baseline in Functional Outcome of Sleep Questionnaire - Short Form (FOSQ-10), a self-administered disease specific quality of life questionnaire, in participants initiated on CPAP and receiving a 3-month follow-up (LOCF applied using 1-month data). A change in 1 unit is felt to indicate clinical significance.
