Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will test the following hypotheses:

1. Treatment of newly diagnosed Obstructive Sleep Apnea (OSA) in acutely ill patients with auto-adjusting Continuous Positive Airway Pressure (CPAP) would result in fewer in-hospital complications, as compared to no treatment (primary outcome).
2. Treatment of newly identified OSA in acutely ill patients with auto-adjusting CPAP would result in shorter length of stay, lower re-admission rate, better blood pressure (BP) control, better long term compliance with OSA treatment, as compared to no treatment (secondary outcomes).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This will be a pilot study performed as a randomized controlled prospective study of patients admitted to the general medical floors at MetroHealth Medical Center (MHMC). This study will be an add-on investigation to an original funded study: "Evaluation of Screening Tools for Obstructive Sleep Apnea (OSA) in Hospitalized Medical Patients: A Validation Study" (the STOMP study).

In the STOMP study, patients admitted Sunday through Thursday (day or night) to MHMC who meet inclusion/exclusion criteria and are willing to participate in the study will complete the STOMP study by undergoing an in-hospital PSG (within 48 hours of admission to the medical floor). Those who's PSG shows clinically significant OSA (an apnea-hypopnea index (AHI) \> 5) will be approached for participation in this study. It is anticipated that at least 50 patients from the STOMP study will be eligible for randomization into this study. Participants will be randomized into an auto-adjusting Continuous Positive Airway Pressure (ACPAP) (ResMed S9) arm or a standard therapy arm (control - no specific therapy for OSA other than possibly supplemental nocturnal oxygen if deemed necessary by the clinicians caring for the patient). Those randomized to ACPAP will continue this therapy until they undergo a repeat diagnostic sleep study (PSG) and then, if indicated, a titration PSG as an outpatient. Those in the standard therapy arm will receive no specific treatment for their OSA until they undergo a a repeat diagnostic study and then, if indicated, a full night titration PSG as an outpatient. Once the titration PSG has taken place, subjects will be changed to fixed CPAP and followed for an additional 6-8 weeks to assess compliance with therapy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ACPAP

Patients in the intervention group will be introduced to the auto-adjusting CPAP (ACPAP) (ResMed S9) during the day and placed on it at night with a nocturnal oximetry and ACPAP download to assess its effectiveness and pressure requirements. The intervention is the application of the ACPAP. The patients will be discharged on ACPAP pressure determined by the ACPAP download (95th percentile pressure in absence of significant air leak) and will be scheduled for an outpatient repeat diagnostic PSG and, if indicated, a full night titration study.

Group Type EXPERIMENTAL

Auto-adjusting CPAP

Intervention Type DEVICE

A CPAP device that auto-adjusts the pressure setting over the course of the night, depending on how the patient is breathing.

Control

The control group will receive nocturnal oxygen or no therapy while in the hospital and after discharge at the discretion of the attending physician. They will be scheduled for outpatient repeat diagnostic PSG and then, if indicated, a full night titration study.

Group Type NO_INTERVENTION
