Brief summary

This is a multicenter, randomized, parallel-group, open label study of the efficacy of AVAPS-AE to prevent re-hospitalization in hospitalized patients with comorbid Chronic Obstructive Pulmonary Disease (COPD).

Detailed description

This is a multicenter, randomized, parallel-group, open label study of the efficacy of AVAPS-AE to prevent re-hospitalization in hospitalized patients with comorbid COPD. Hospitalized patients with comorbid COPD who are at high risk for readmission will be recruited. Specifically patients with comorbid COPD who are to be discharged with (a) admission diagnosis of COPD (GOLD stage II or greater); AND (b) either a prior non-elective hospitalization (one in the past 12 months) OR active smoker. Such participants will undergo questionnaire-based screening for sleep-disordered breathing (STOP-BANG questionnaire) and if they have a high risk for Sleep Disordered Breathing (SDB) (\> 3 points) will undergo an overnight portable sleep study for screening prior to hospital discharge (AHI \> 10 per hour; \>3% oxygen desaturation for hypopneas). After randomization and prior to discharge, participants will either be initiated on AVAPS-AE therapy (intervention arm) for 60 days or will be referred to the sleep center for further diagnostic testing and therapy initiation (standard of care arm). Participants will complete quality of life questionnaires Functional outcomes of sleep questionnaire (FOSQ) at baseline (in-person), and in 30 and 60 days (by mail) post discharge. Information regarding hospital admission, diagnostic tests, medication changes, and procedures will be collected from all participants. Discharge summaries of re-hospitalizations and office or ER visits, as well as diagnostics tests and therapies received will be collected for measuring healthcare costs. Participants will have an option to enroll in a registry for a 3 year follow-up and will also be queried on a yearly basis regarding hospitalizations, cardiovascular events, and assessment of vital statistics in the National Death Index registry. The study will conclude when all randomized participants have been followed for a minimum of 60 days.

MeasureTime frameDescription
Change in Quality of Life (FOSQ) at 30 and 60 Days30 and 60 days post-dischargeFOSQ is a quality of life questionnaire for sleep disorders. It's a 30 question survey with 5 subgroups: general productivity (8 questions), social outcome (2 questions),activity level (9 questions), vigilance (7 questions) and intimate relationships & sexual activity (4 questions). Scores are provided on a 0 to 4 scale: 0- I don't do this activity for other reasons or missing response 1- Yes, extreme difficulty 4- no difficulty The average score was calculated based upon average sub-scores. The total score was, calculated using the mean of the subscale scores and multiplying the mean by the number of subscales. The range of scores for the total score is 5-20. The measures are designed to assess the impact of disorders of excessive sleepiness on activities of everyday living and the extent to which these abilities are improved by effective treatment. The lower the score the more difficulty a person has carrying out certain activities because they are too sleepy or tired.
