Objectives: This study aimed to determine sleep quality, frequency and
severity of dyspnoea in COPD patients and to evaluate the relationship
between dyspnoea severity and sleep quality. Method: The sample of the
study consisted of 110 patients admitted to the Chest Diseases
polyclinic of a private hospital and diagnosed as COPD for at least one
year. The data of the study were collected using the "Individual
Information Form", "COPD and Asthma Sleep Scale (CASIS)" and "Medical
Research Council (MRC) Dyspnoea Scale\u201d. Results: It was found
that 6.4% of the patients did not experience dyspnoea, 34.5% had mild,
40.9% had moderate, and 18.2% had severe dyspnoea. The mean CASIS score
of the patients without dyspnoea was 29.08\ub17.83, with mild
dyspnoea was 40.22\ub19.30, with moderate dyspnoea was
50.31\ub18.97 and with severe dyspnoea was 56.96\ub113.13. There
was a statistically significant difference between dyspnoea severity
and mean CASIS score (p=0.001). Correlation analysis between MRC
dyspnoea scale and CASIS score showed a significant positive
correlation (r=0.61 p=0.001). Conclusion: It was concluded that the
majority of COPD patients had moderate or poor sleep quality and
dyspnoea. As dyspnoea severity increases, sleep quality decreases
