NCT03647891

Brief Summary

The purpose of this study is to determine whether early diagnosis of obstructive sleep apnea and initiation of and adherence to CPAP therapy in hospitalized cardiac patients would impact 30-day hospital readmission rates.

CPAP Intervention Pathway

EXPERIMENTAL

Patients will receive continuous positive airway pressure (CPAP) therapy in the hospital followed by home CPAP therapy. Their home CPAP therapy will include wireless connectivity, which includes adherence data. Furthermore, the patients will be entered into our usual automated platform (USleep; ResMed Corp) in which patients with suboptimal CPAP use will be sent messages (based on patient preference) in order to ensure adherence to therapy. This platform is already a standard part of our usual care. The patients will receive CPAP in addition to contemporary standard of care pharmacotherapy for their underlying cardiac condition(s). They will follow up at the Fontana Sleep Center within 1 month after discharge for assessment of CPAP use and asked to complete a questionnaire packet. Patients will be followed during the 30-day period and assessed for readmission rates, time to readmission, adherence to CPAP therapy, and presence of symptoms.

Device: Continuous Positive Airway Pressure

Usual Care Pathway

NO INTERVENTION

Patients will receive contemporary standard of care pharmacotherapy for their underlying cardiac condition(s) and will not receive CPAP therapy for the duration of the study. They will be asked to follow up at the Fontana Sleep Center within 1 month after discharge for a repeat outpatient portable sleep study and asked to complete a questionnaire packet. The results of the outpatient portable sleep studies will be compared with the in-patient portable sleep study. Patients will also be asked to follow up with the Fontana Sleep Center within 1 month after discharge for assessment of primary and secondary outcomes. Patients will be followed during the 30-day period and assessed for readmission rates, time to readmission, adherence to CPAP therapy, and presence of symptoms.

Interventions

CPAP is an FDA approved therapy machine for patients diagnosed with OSA. CPAP provides positive air pressure to the patients throat to ensure the patients airway stays open during sleep. CPAP is the gold standard treatment for OSA, but there is limited research that demonstrates whether or not CPAP can improve clinical outcomes in patients with cardiovascular disease. Therefore, our investigators plan to initiate CPAP therapy in patients hospitalized for cardiovascular disease to investigate whether there is an improvement in cardiac function and clinical outcomes (e.g. mortality).
