Experimental: CPAP Intervention Pathway
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
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).
No Intervention: Usual Care Pathway
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.
- Hospital readmission [ Time Frame: 30 days ]Number of occasions patient has been admitted to the hospital
- Mortality rates [ Time Frame: 30 days ]Number of patients who have died
- Clinic and urgent care visits [ Time Frame: 30 days ]Appointments with any medical providers (sleep, cardiac, primary) at a clinic or urgent care facility
- Off work orders [ Time Frame: 30 days ]Note from provider ordering/requesting patient to be dismissed from work for medical reasons (sick, injured, etc.)
- STOP BANG [ Time Frame: 30 days ]Snoring, tiredness, observed apnea, blood pressure, body mass index, age, neck circumference, and gender (STOP BANG) is the name of a OSA screening questionnaire. Questionnaire contains 8 "Yes/No" questions and the number of "Yes" answers provide a total score (range 0-8). Scores of at least 3 are typically considered to indicate risk of OSA.
- Epworth Sleepiness Scale (ESS) [ Time Frame: 30 days ]Epworth Sleepiness Scale measures degree of sleepiness. 8 scenarios are described and the responder indicates their likelihood of dozing unintentionally (range 0-3). A total of the scores are added (range 0-24) and typically scores of at least 11 indicate excessive sleepiness.
- EQ5D-5L [ Time Frame: 30 days ]EuroQoL 5-dimension 5-level measures health-related quality of life that can be used for wide range of health conditions. The questionnaire consists of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The patients can rate each dimension based on 5 level severity scale: no problems, slight problems, moderate problems, severe problems and extreme problems.This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.
- PROMIS [ Time Frame: 30 days ]Patient Reported Outcome Measurement Information System is a 10 item questionnaire that measures physical, mental, and social health in adults. It can be used on the general population and patients with chronic conditions. Patients rate their health based on a severity scale of 1-5 (1 indicates poor health) and the scoring system allows each question/item to be evaluated separately.
- Comparing inpatient portable monitor versus 30-day follow up portable monitor results in usual care group [ Time Frame: 30 days ]Evaluating the change of sleep diagnostic test results from the hospital to 1-month after being discharged (only for patients enrolled in the Usual Care pathway)
