Study Overview
Brief Summary
Sleep-disordered breathing (SDB) remains under-treated in individuals living with spinal cord injuries and disorders (SCI/D). The investigators' aim is to test a program that addresses challenges and barriers to positive airway pressure (PAP) treatment of SDB among patients with SCI/D. The investigators anticipate that patients who receive this program will have higher rates of PAP use and will demonstrate improvements in sleep quality, general functioning, respiratory functioning and quality of life from baseline to 6 months follow up compared to individuals who receive a control program. This work addresses critical healthcare needs for patients with SCI/D and may lead to improved health and quality of life for these patients.
Detailed Description
This proposal aims to test the efficacy of a comprehensive approach to improving positive airway pressure (PAP) therapy acceptance and adherence and sleep quality among patients with SCI/D. The proposed study is very relevant to the mission of the VA in promoting optimal health for all Veterans, including those with disabilities. To this end, this study is a randomized controlled trial (RCT) comparing the efficacy of a combined sleep and PAP adherence program, called the "BEST" program (Best practices PAP + patient Education +ongoing Support and Training). The central aim of this proposal therefore is to test the efficacy between two PAP adherence programs. The study has two main aims. First, the investigators aim to test the efficacy of the educational program in improving adherence to PAP therapy for the first 6 months of use (with data available for some subjects for up to 12 months). Second, the investigators will evaluate the impact of the program on sleep quality and on three key areas of function: general functioning (using measures specific to SCI/D patients), respiratory functioning (via spirometry) and quality of life (assessed with measures appropriate for use with patients having limited mobility) over the 3-month intervention period. The investigators will also explore whether the intervention is more effective for some subgroups of patients than others. The proposed work is very relevant to VA's patient care mission, addressing a critical need for patients who suffer from disparity in access to high quality care because of their disabilities. The investigators anticipate that the investigators' work will yield significant new knowledge that improves the health and quality of life for Veterans living with SCI/D.

Arms & Interventions
The BEST Program
a combined sleep and PAP adherence program, called the BEST program (Best practices PAP + patient Education + ongoing Support and Training)
Intervention: Best practices PAP + patient Education +ongoing Support and Training (Behavioral)
Sleep Education and standard SDB treatment
This program includes non-directive sleep education plus standard treatment of SDB.
Intervention: Sleep Education (Behavioral)
Outcomes
Primary Outcomes
PAP Adherence
Time Frame: 90 days
Number of nights positive airway pressure (PAP) was used \>=4 hours during the first 90 days measured by remote monitoring. Scores range from 0 to 90 days. Higher scores indicate better outcome.
Subjective Sleep Quality Was Measured by The Pittsburgh Sleep Quality Index (PSQI)
Time Frame: 90 days
The Pittsburgh Sleep Quality Index (PSQI) is an 18-item questionnaire that assesses sleep quality and disturbances over the past month. The PSQI is sensitive for distinguishing normal and abnormal sleepers and has good test-retest reliability. The investigators will use the 3-factor scoring, which has been shown to have superior psychometric properties. This will be used as the main independent measure of sleep quality. The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality
Secondary Outcomes
- Functional Status Was Measured by CHART Questionnaire.(90 days)
- Fatigue Symptoms(90 days)
- Quality of Life Was Measured by WHO-QOL BREF Questionnaire(90 days)
- Depressive Symptom Severity(90 days)
- Epworth Sleepiness Scale(90 days)
- Respiratory Function: Spirometry and Respiratory Muscle Force(90 days)
