Initiation of CPAP for Newly Diagnosed OSA in Hospitalized Heart Failure Patients

Not Applicable

Completed

Conditions: Heart Failure
Sleep Apnea, Obstructive

Interventions: Device: Continuous Positive Airway Pressure (CPAP)

Registration Number: NCT03056443

Lead Sponsor: West Virginia University

Brief Summary: The study aimed to examine the effect of Continuous Positive Airway Pressure (CPAP) initiation for newly diagnosed obstructive sleep apnea (OSA) in hospitalized heart failure patients on reducing 30-day hospital readmission rate through a clinical trial.

Detailed Description: Following consent adult patients hospitalized with a medical history of heart failure and meeting study eligibility criteria will be screened for obstructive sleep apnea using the Ohio Sleep Medicine Institute Preoperative Questionnaire.

If the probability of sleep apnea is high (Sleep apnea clinical Score \>15) then participants will complete the Epworth Daytime Sleepiness scale and the Minnesota Living with HeartFailure questionnaire. The patient will then be evaluated by the sleep medicine team with a portable polysomnography monitor which has been shown to be equivalent to standard in-laboratory polysomnography. All participants with apnea-hypopnea index (AHI) ≥ 5events/h in whom sleep disordered breathing is confirmed by sleep medicine physician will be eligible for randomization.

Participants will be randomized into an auto-adjusting Continuous Positive Airway Pressure (CPAP) group or standard of care (control) group.

CPAP Arm (Intervention): CPAP education and discharge with auto-adjusting Continuous Positive Airway Pressure (CPAP) in addition to usual standards of clinical care for heart failure. The auto-CPAP group will be scheduled for follow-up with a phone call at 2 - 3 weeks post discharge, then in sleep medicine clinic at 1 month (+2 weeks) and 6 months (+2 weeks) to assess their progress on CPAP.

Standard of Care Arm (Comparator): CPAP initiation per standard of care based on approval by insurance company and DME company with management as per usual standards of clinical care for heart failure. This group will be scheduled for follow-up with a phone call at 2- 3 weeks post discharge and then in sleep medicine clinic at 1 month (+2 weeks) and 6 months (+2 weeks) to assess their progress.

Primary Outcome Measures

Name	Time	Method
All-cause Hospital Readmission Within 30 Days of Hospital Discharge.	From hospital discharge to any hospitalization readmission within 30 days from discharge	Thirty-day hospital readmission will be defined as a hospitalization or visit to the emergency department (ED) for a cardiac cause \> 48 h after discharge. A readmission will be defined as a hospitalization for any reason within 30 days after discharge, and only the first readmission will be counted in case of multiple readmission in the 30-day period.
