Evaluation of sleep disorder and its effective factors in patients with an ischemic heart disease in the CCU ward of Kashan Shahid-Beheshti Hospital during 2017-2018

Complaints of sleep disorders are common in ischemic heart patients, even after taking sleeping drugs. Evaluation of the causes of sleep disorders and modifying these factors that lead to the progression of patients' treatment is very important. Therefore, this study aimed at investigating sleep disorders and their effective factors in cardiac ischemic patients admitted to the cardiac care unit (CCU) with the use of sleeping drugs. This descriptive analytical study was conducted on 250 patients in the CCU ward of Kashan Shahid Beheshti Hospital, during 2017-2018, using the random sampling method. Data were collected by a specific questionnaire with 0.90 validity and 0.76 reliability. In total, 80.4% of the patients reported a degree of sleep disorders. The most common problems were observed subsequently in the onset and duration of sleep, sleep disorders due to environmental factors, daily dysfunction, sleep disorder due to heart disease, and respiratory problems during sleep. Among the environmental factors, there was a significant relationship between sleep disorders and lack of a comfortable bed condition (OR=20.42), continuous illumination of the lights (OR=19.05), feeling of hot or cold (OR=15.44), feeling of the unpleasant odor (OR=13.60), and high levels of noise in the ward (OR=12.22). According to the results of this study, paying more attention to these patients, comprehensive review of them, and the establishment of a care plan for the improvement of sleep conditions are necessary in hospitalized patients.
