  Purpose

Patients hospitalized with congestive heart failure (CHF) on non-Intensive Care Unit medical services will be screened by overnight oximetry. Patients with positive screens will be referred for treatment of Sleep Apnea. They will be followed to determine if treatment of Sleep Apnea improves their quality of life and decreases their readmissions to the hospital.

Primary Outcome Measures:
  • Hospital Readmission Rate [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • Hospital Readmission Rate [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Hospital Readmission Rate [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Epworth Sleepiness Scale [ Time Frame: Change from Baseline to 6 weeks ] [ Designated as safety issue: No ]
    Chance of Dozing Off - Scale: Never, Slight, Moderate, High

  • Functional Outcome of Sleep Quality [ Time Frame: Change from Baseline to 3 months ] [ Designated as safety issue: No ]
    Level of Difficulty Performing Everyday Activities - Scale: Don't do this activity, No difficulty, A little difficulty, Moderate difficulty, Extreme difficulty

  • Residual Apnea Hypopnea Index [ Time Frame: at 6 weeks ] [ Designated as safety issue: No ]
    This is a data download from the Continuous Positive Airway Pressure machine, indicating the effectiveness of the patient's breathing while wearing the machine.

  • % of nights with greater than 4 hours use of Continuous Positive Airway Pressure [ Time Frame: at 6 weeks ] [ Designated as safety issue: No ]
    Compliance for a given night would be 4 hours use or more.

  • % of nights with greater than 4 hours use of Continuous Positive Airway Pressure [ Time Frame: at 3 months ] [ Designated as safety issue: No ]
    Compliance for a given night would be 4 hours use or more.

Patients with Congestive Heart Failure

Screening Oximetry Study

Polysomnogram Sleep Study

Other: Screening Oximetry Study
Patients hospitalized with Congestive Heart Failure on non-Intensive Care Unit Medical Services will have oximetry study performed by Oxynet system for minimum of 4 hours at night.
Other Name: Oxynet
Other: Polysomnogram Sleep Study
Patients with positive oximetry screens will have Polysomnogram Sleep Study at the Sleep Center and be referred to the Sleep Center physicians for evaluation and treatment.

Detailed Description:

Patients hospitalized with Congestive Heart Failure on non-Intensive Care Unit Medical Services will have oximetry study performed by oxynet system for minimum of 4 hours at night. Patients with positive oximetry screens will have Polysomnogram performed at the Sleep Center, then be referred to the Sleep Center physicians for evaluation and treatment. Patients will be followed for up to one year to determine if the screening and treatment for Sleep Apnea improves their Quality of Life and decreases hospital readmission rates.
