Patients in this group will receive self-management education during the 3 days when they are in the hospital. On the first day of the training, COPD disease, causes of the disease, symptoms, reasons for alleviating complaints, practical information for living comfortably with COPD will be given. On the second day, emergency situations in COPD, what is an exacerbation and prevention suggestions and diaphragmatic breathing-cough exercises will be taught. On the last day, training will be given on pursed lip breathing, medication use, oxygen and nebulizer treatments. Patients will receive their first call one week after discharge. The calls will be scheduled weekly during the first month, biweekly in the second month, and monthly starting from the third month. During the calls, it is planned to repeat the educational content and answer the patient's questions. All scales are planned to be re-administered at 1, 3, and 6 months.

It is used to rate the effects of breathlessness in daily activities. The scale was developed and modified by the British Medical Research Council (MRC) to determine the course of breathlessness in respiratory diseases. The MMRC is a five-item scale based on various movements that cause shortness of breath.

The Turkish reliability and validity of the scale, which consists of eight questions to assess health status in COPD, was conducted by Yorgancıoğlu et al. in 2012. The COPD Assessment Test provides assessment of conditions such as sputum, shortness of breath, cough, fatigue, and sleep. Each question is scored between 0 (no symptoms) and 5 (severe symptoms). The scores of the questions in the test are between "0-40". The higher the score, the more severe the disease and the worse the health status.

It is a 10-item questionnaire (4 items for symptoms, 4 items for functional status and 2 items for mental status) that measures clinical control to assess functional status, mental status and symptoms and is valid and reliable in Turkish.

The Modified Borg Dyspnea Scale was developed by Borg in 1970 to measure the effort expended during exercise and the level of dyspnea felt at the maximum level at which exercise has to be stopped. The severity of dyspnea on the scale is expressed by ten items defined from "0 (none)" to "10 (very severe)". The severity of exertion during exercise is graded according to this scoring to determine the level of dyspnea.

The scale was developed by Kearney and Fleicher (1979) in English with 43 items, and its Turkish validity and reliability was shortened to 35 items by Nursen Nahcivan (Nahcivan, 1994; Nahcivan 2004). The scale focuses on individuals self-assessment of their involvement in self-care activities. Each statement is scored from 0 to 4. Individuals orientation towards self-care is determined by participants responses on a 5-point Likert-type scale.
