Chronic obstructive pulmonary disease (COPD) and sleep apnea are overlap syndromes and cause an increased systemic inflammatory response, a weakened immune system, poor cognition, and physical inactivity in addition to COPD patients’ comorbid factors causing an overall decreased functional status. Feasibility testing of physiologic measures is needed to promote more accurate screening of sleep-disordered breathing in patients with COPD. This study hypothesizes more effective screening with utilization of overnight oximetry and end-tidal carbon dioxide level monitoring to detect sleep-disordered breathing. This descriptive study will test the feasibility of completing OSA and central sleep apnea screening in hospitalized patients with COPD who have not been diagnosed with a sleep-related breathing disorder. The aim of this study is to evaluate the feasibility of study a) enrollment (recruitment, efficiency, attrition, problems), b) data collection (technology transfer of data, instruments, time required, missing data), and c) clinical data collection from electronic medical record (inpatient and private practice settings). The Chronic Disease Self-Management Theory by Dr. Katie Lorig was utilized as the theoretical framework for this study to incorporate self-management in treatment of these two chronic disorders. This study looks at participants (N=10) who were recruited from Bryan Health in Lincoln, NE and followed post-discharge at Nebraska Pulmonary Specialties, LLC. Following completion of self-reported measures, patients will have overnight oximetry and end-tidal CO2 measured 1-2 days prior to discharge. Study information will be given to their providers at Nebraska Pulmonary Specialties and sleep study data will be obtained if ordered. Descriptive statistics will be completed to evaluate the feasibility of the study after completion. Recruitment and enrollment are underway and results are pending.
