Sleep Quality and Daytime Sleepiness in Patients with Chronic Obstructive Pulmonary Disease in a Tertiary Care Hospital: An Observational Study

The study examined sleep quality and daytime sleepiness in 398 patients with chronic obstructive pulmonary disease (COPD) from March to June 2025. Results showed that 52.78% of patients had poor sleep quality and 46.23% suffered from excessive daytime sleepiness. Most participants (77.89%) had moderate-to-very severe COPD with a mean CAT score of 24.36 points. Frequent disease exacerbations occurred in 63.07% of patients. Patients had prolonged sleep latency, reduced sleep duration (averaging 5.55 hours), and common daytime dysfunction. The study confirmed that poor sleep quality and daytime sleepiness should be routinely screened in COPD patients, as they are significantly associated with disease severity and exacerbation frequency.
