Detailed Description

Aim of research The purpose of this study is to evaluate the effectiveness of teaching breathing exercises to COVID-19 patients after intensive care. Type of research The research is a randomized controlled and pretest-posttest applied design. Research Population and Sample Selection The population of the research will consist of patients who have been previously admitted to the intensive care unit of the hospital where the research will be conducted and who meet the research criteria. In order to determine the sample size, a priori power analysis was performed and it was determined that at least 35 patients were required for each of the intervention and control groups in order for the power of the study to exceed 80% at the 95% confidence interval, 0.05 significance level and medium effect size. Considering that there may be data loss due to various reasons, 80 patients are planned to be included in the sample of the study. Data collection tools and features The data of the study are Patient Information Form and Data Registration Form, Care dependency scale, Health Screening short form-36, Saint George Respiratory Questionnaire (SGRQ), Respiratory Function Test, Respiratory Exercises Information Booklet and Breathing Exercises Information Booklet. Data Registration Form. It is the form in which the blood pressure, pulse, respiration, body temperature, oxygen saturation values taken twice a day, before and after exercise, are recorded. Patient Identification Form. Patients have name-surname, age, gender, height, weight, BMI, educational status, occupation, marital status, clinical data (history, family history, medications used, use of assistive devices, smoking history, respiratory system evaluation) and exercise habits. Care dependency scale. In the study, this scale was used to determine the care dependency of the patients. The lowest score obtained from the scale is 17 and the highest score is 85. A high scale score indicates that the individual is independent in meeting their care needs, while a low scale score indicates that the individual is dependent on meeting their care needs. Baseline dyspnea scale Mahler et al. It was developed by 1984. The validity and reliability of the Basal Dyspnea Scale in our country have been made by different researchers, and the scale evaluates dyspnea due to activity; It measures in three different areas: functional status (level of performing activities of daily living), effort capacity (difficult efforts to perform activities) and work capacity. Health Screening short form-36 Short Form-36 (Short Form-36 Health Survey - SF-36) will be used to assess overall health-related quality of life. SF-36 is a self-rating scale. Subscales evaluate health on a scale of 0-100, with 0 indicating poor health and 100 indicating good health. Saint George Respiratory Questionnaire (SGRQ) The Saint George Respiratory Questionnaire (SGRQ) will be used to assess the disease-specific quality of life. The SGRQ is a questionnaire in which patients self-answer questions. The questionnaire, which consists of three categories, questions the effects of symptoms, activity and illness on daily life. It is considered to be more standardized than other health-related quality of life questionnaires. It is mostly used in COPD, asthma and bronchiectasis. It has an evaluation scale between 0-100 points in the questionnaire consisting of a total of 76 questions. Zero indicates best health and 100 indicates worst health. Pulmonary Function Test Pulmonary function tests are an objective method used in the diagnosis and follow-up of the disease. Pulmonary function tests were performed in a sitting position with a computer compatible spirometer Research Intervention Materials Breathing Exercises Information Booklet; Respiratory Exercises Information Booklet created by the researchers in line with the literature review; It includes information about the disease and its treatment, treatment methods of the disease, lifestyle changes that are effective in respiratory management, and the importance of compliance with treatment. Breathing Exercises Video CDs; The content will be created by the researchers in line with the literature review. Videos; It includes information about the disease and its treatment, treatment methods of the disease, lifestyle changes that are effective in respiratory management, and the importance of compliance with treatment. The content of the training booklet and the training videos will be the same. Data Collection All patients in the intervention and control groups who meet the inclusion criteria will be verbally informed about the purpose of the study and the method of application. Informed Consent Form will be filled in for the patients who agree to participate in the study. Then, pre-test forms (Patient Identification Form, Care dependency scale, Health Screening short form-36, Saint George Respiratory Questionnaire (SGRQ)) will be filled in by face-to-face interview method for all patients in the intervention and control groups. Randomization in the study will be determined randomly by using a computer program (researcher randomizer), provided that the number of individuals in the intervention and control groups is equal regardless of the characteristics of the participants such as age and gender. Enterprise Group; The vital signs of the patients in the intervention group, for which the necessary forms are filled, will be taken and the Data Registration Form will be filled. Afterwards, patients will have Pulmonary Function Tests and the results will be filled in the Respiratory Function Test Report. Afterwards, breathing exercises will be taught in line with the Respiratory Exercises Information Booklet and Respiratory Exercises Information Booklet. As long as the patients stay in the hospital, it will be checked whether they do their exercises. When the patients are completely discharged, they will be called by phone and reminded to do their exercises three times a day. In this way, patients in the intervention group will be followed remotely by tele-nursing for 8 weeks. At the end of the 8th week, the patients will be called to the hospital and the recorded data will be received from the patients. Then, as a posttest, the patients will have Pulmonary Function Tests and the results will be filled in the Respiratory Function Test Report. Likewise, as posttest (Care dependency scale, Health Screening short form-36, Saint George Respiratory Questionnaire (SGRQ)) forms will be filled again. control group; No intervention will be made in the control group. For the final test, the results will be filled into the Respiratory Function Test Report after 8 weeks. Likewise, as posttest (Care dependency scale, Health Screening short form-36, Saint George Respiratory Questionnaire (SGRQ)) forms will be filled again. Evaluation of data The data will be evaluated in the SPSS (Statistical Package for Social Sciences for Windows, Version 22.0) package program. Research Ethics Ethical permission was obtained from the Ethics Committee of Atatürk University Faculty of Medicine for the study to be carried out. Institutional permission was obtained from the hospital where the research would be conducted. In addition, informed consent will be obtained from the participants who agree to participate in the study. The research will be in accordance with the Declaration of Helsinki.
