Assessment of illness acceptance by patients with COPD and the prevalence of depression and anxiety in COPD

Background: COPD is a civilization disease. It affects up to 8%-10% of population > 30 years of age. Coexistence of depression occurs in 20%-40% of patients with COPD. Depression and anxiety reduce compliance and worsen prognosis. Objective: The aims of this study were to determine the degree of illness acceptance among patients with COPD, to examine the relation between disease acceptance and perceived anxiety and depression, and to verify which of the sociodemographic and clinical factors are associated with illness acceptance, anxiety, and depression. Materials and methods: The study included 102 patients with COPD (mean age 65.8 years), hospitalized due to exacerbations. Acceptance of Illness Scale and Hospital Anxiety and Depression Scale were used. For statistical analysis, Student's t-test and Pearson's r correlation coefficient were carried out. Results: The overall illness acceptance level was moderate with a tendency toward lack of acceptance (mean 20.6, standard deviation [SD] 7.62). The overall scores were 10.2 (SD 3.32) for anxiety and 10.8 (SD 4.14) for depression, which indicate borderline or high intensity of these symptoms. Acceptance of illness was negatively correlated with the intensity of depression symptoms (r=-0.46, P < 0.05). Intensity of depression was significantly associated with intensity of smoking, duration of the disease, severity of dyspnea, and living in a rural area. Conclusion: Early identification and assessment of depression and anxiety symptoms allow health care providers to offer patients at risk of depression a special medical supervision. Rapid start of antidepressant therapy may increase illness acceptance and improve prognosis among patients with COPD.
