July 22, 2020 updated by: Philips Respironics

A Pilot, Multi-Center, Randomized, Open-Label, Parallel Group Study to Assess the Effects of a Novel Application of Averaged Volume Assured Pressure Support Ventilation (AVAPS-AE) Therapy on Re-hospitalization in Patients With Sleep-Disordered Breathing With Co-morbid COPD

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).

Study Overview

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: AVAPS-AE Non-invasive ventilation therapy
Participants will be initiated on AVAPS-AE therapy (intervention arm) for 60 days. AVAPS-AE is a mode of therapy (Philips Respironics Inc, Monroeville, Pa) with potential advantages over the currently established modes of non-invasive positive pressure ventilation (CPAP and bilevel therapy). This mode of therapy incorporates AVAPS (automated adjustable Inspiratory Positive Airway Pressure (IPAP) setting to maintain target ventilation with a settable rate of change), Auto Expiratory Positive Airway Pressure (EPAP) and Auto Back up Rate.
Participants will use the device greater than or equal to 4hrs per night for the 60 days after discharge.
No Intervention: Standard of Care Group
Evaluation and treatment of the participant's sleep disordered breathing will be per their participant's health care provider's usual care pathway.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants Enrolled Requiring Emergent Healthcare (Such as Re-hospitalization, Unscheduled Physician Office Visits, Urgent Care Visits or Emergency Room Visits).
Time Frame: 60 days post-discharge
Evaluate the effects of novel application of Averaged Volume Assured Pressure Support (AVAPS-AE) therapy on the number of participants with emergent and non-emergent healthcare utilization with sleep-disordered breathing who are hospitalized with co-morbid Chronic Obstructive Pulmonary Disease (COPD), number of participants enrolled.
60 days post-discharge
Composite End-point of Time (# of Days) to Occurrence of Emergent Healthcare Utilization (Such as Re-hospitalization, Unscheduled Physician Office Visits, Urgent Care Visits or Emergency Room Visits).
Time Frame: 60 days post-discharge
Evaluate the effects of novel application of Averaged Volume Assured Pressure Support (AVAPS-AE) therapy on time to (# of days) emergent and non-emergent healthcare utilization in patients with sleep-disordered breathing who are hospitalized with co-morbid Chronic Obstructive Pulmonary Disease (COPD).
60 days post-discharge

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Healthcare Costs
Time Frame: 60 days post-discharge
Evaluate the effects of novel application of Averaged Volume Assured Pressure Support (AVAPS-AE) therapy on the number of emergent and non-emergent healthcare utilization over 6 months; costs related to re-hospitalization; number of visits to physician offices or emergency rooms, and health-related quality of life (disease-specific and general HR-QOL measures).
60 days post-discharge
Change in Quality of Life (SF-36) at 30 and 60 Days
Time Frame: 30 and 60 days post-discharge
Evaluate the effects of novel application of Averaged Volume Assured Pressure Support (AVAPS-AE) therapy on health-related quality of life. The Short Form 36 (SF-36) is a set of quality of life measures. Participants were asked at 30 days and 60 days in general what their overall health was. On a scale of 1 to 5 -1 being excellent, 5 being poor.
30 and 60 days post-discharge
Change in Quality of Life (FOSQ) at 30 and 60 Days
Time Frame: 30 and 60 days post-discharge

FOSQ 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.
