Abstract
Abstract Introduction Sleep disturbances are common in COPD. Hospitalization due to COPD exacerbations likely have a negative impact on sleep in these patients and may contribute to their recovery. The aim of this study was to measure the prevalence of sleep disturbances in hospitalized patients with COPD and characterize their impact by use of the Functional outcomes of Sleep questionnaire (FOSQ). Methods The study was done at a community hospital. We included all patients who were admitted with a diagnosis of acute COPD exacerbation. Patients were administered the FOSQ on the day of discharge. Standard statistical methods were used to analyze the data Results A total of 54 patients - 28 males and 26 females filled out the questionnaire completely and were included in the analysis. The mean age was 66 +/- 14 years. The average FOSQ was 15 +/- 7. 60% of the patients had a FOSQ of <17.9 showing a high prevalence of sleep morbidity. Individual domains of the FOSQ -( mean +/- SD) showed the following values : General productivity of 3 +/- 2, vigilance 2.5 +/- 2.2, activity 7.2 +/- 2.2, and social outcomes 0.6 +/- 0.9 respectively. Vigilance scores and social outcomes domains were seen to be lower than those previously reported in patients with severe sleep apnea while activity domains were seen to be higher. Conclusion There is significant sleep-related morbidity in hospitalized patients with COPD exacerbation, with particularly high prevalence of overall sleep disturbances even after recovery and at the time of discharge. Domains related to social outcomes were the most affected, and vigilance domain scores were critically low. These data point to an urgent need for clinicians to include assessment of sleep quality while discharging patients with COPD exacerbations and providing them appropriate counseling. Future studies should focus on the best interventions to improve sleep in the patients and measure its impact on their lung function. Support (If Any) None
