The quality of sleep, anxiety and depression of COPD patients (115) who were admitted to a university hospital's pulmonary ward were investigated. Data were collected using a personal information form, the hospital anxiety and depression scale and the Pittsburgh Sleep Quality Inventory. It was determined that 97% of the patients' quality of sleep was poor, 90% had high anxiety and 91% had high depression. It was determined that there was a significant correlation between duration of illness and quality of sleep (r=.340, p < 0.05) and between age and quality of sleep (r=.186, p < 0.05), as the duration of illness increased and the age increased the quality of sleep decreased, and a significant correlation was found between age and depression (r=.115 p < 0.05), as the individual's age increased the depression score also increased, and a significant correlation was found between anxiety and depression (r=.216 p < 0.05), as the anxiety increased the depression also increased, and patients who had high anxiety and depression scores had poor quality of sleep. The COPD patients experience problems with sleep, anxiety and depression. For this reason COPD patients who are admitted to the hospital need to have their quality of sleep, anxiety and depression levels routinely evaluated in the same way as their physical condition.
