The effect of nursing approach based on Meleis's transition theory on cardiac quality of life and adaptation to disease in patients with acute myocardial infarction.

This research was planned with the idea that the approach developed based on Meleis's Transition Theory could facilitate the illness-health transition process in patients, increase their healthy behavioral gains, increase the quality of care, reduce rehospitalizations, reduce the mortality rate due to MI, and contribute to the nursing literature.

Coronary artery disease (CAD) is one of the important health problems with high morbidity and mortality in the world and in our country. More than 9 million people die due to CAD every year in the world, and this condition constitutes 14.8% of all deaths . TEKHARF study data in 2017 show that CAD mortality and prevalence are higher in Turkish adults compared to European countries. Myocardial infarction (MI) is defined as CAD that develops due to prolonged ischemia and shows clinical features including electrocardiographic findings, elevation of biochemical markers of myocardial necrosis, and imaging. According to 2015 data of the American Heart Association, the prevalence of MI is 3.3% in men and 1.8% in women aged 40-59; It was announced as 11.3% in men and 4.2% in women between the ages of 60-79. When looking at the 2018 data of the Turkish Statistical Institute (TUIK), circulatory system diseases are in the first place with 38.4% (162 thousand) of all death cases (423 thousand). Ischemic heart disease constitutes 39.7% of deaths due to circulatory system diseases . In the Heart Disease Risk Factors in Turkish Adults study, the annual CAD death rate in European countries was reported as 2 to 8 per thousand in men and 0.6 to 3 per thousand in women between the ages of 45-74. In our country, this rate was found to be 7.6 per thousand in men and 3.8 per thousand in women in the same age range . According to the data of the Ministry of Health, the incidence of myocardial infarction is stated as 156,300 per hundred thousand and its prevalence as 0.648 per thousand. MI is generally seen as an important health problem that is difficult to adapt to because it is more common in the productive age group, causes serious problems such as post-acute rhythm problems, development of heart failure, recurrence of MI, ischemia, ventricular fibrillation, post-infarction angina, causes loss of work force, and has a negative impact on quality of life and the economic burden it brings. Social, psychological and physical limitations after MI negatively affect individuals' quality of life and self-efficacy levels and make compliance difficult . Studies have shown that patients have difficulty in making lifestyle changes after MI, and this increases the risk of re-infarction . The study conducted by Ens and colleagues (2019) also states that most patients who have had MI do not know cardiovascular disease risk factors, symptoms and how to make lifestyle changes. In another study on compliance with medication use, it was found that a significant portion of patients with acute coronary syndrome after MI had impaired treatment compliance after one year. The main goal in the treatment of MI is to prevent cardiac recurrence and complications and to adapt to lifestyle changes. Lifestyle changes in the management of myocardial infarction risk factors (smoking, alcohol, obesity, hyperlipidemia, hypertension, diabetes, physical activity, weight control and diet) are emphasized by the American Heart Association and the European Society of Cardiology. Lifestyle changes after MI reduce the risk of infarction and mortality. International guidelines emphasize that exercise programs after myocardial infarction reduce the mortality rate by 20%, smoking cessation reduces the risk of a new infarction by 50%, and dietary changes and the use of lipid-lowering drugs reduce the risk of a new infarction by 34% and total mortality by 30%. . It is reported that ensuring compliance will be important for patients to return to their active lives and continue their lives in a healthy way after MI. Many interventions such as home visits, telephone follow-up and motivational interviews, increasing self-management, providing education and counseling are used to increase compliance and quality of life. Among these interventions, education is reported to be an effective method in increasing awareness and responsibility, contributing to lifestyle changes, and telephone follow-up is an effective method in increasing quality of life and self-efficacy, reducing stress, and preventing repeated hospitalizations . It is stated that theory-based interventions are effective in increasing the effectiveness of nursing interventions . One of these theories is the theory of transitions founded by Meleis. Meleis defines transitions as new situations that occur as a result of changes in life, health, illness, personal and social relationships . Being diagnosed with a disease, becoming a mother, taking on a new task, changing profession, being hospitalized or discharged are all situations that involve transitions. Change and development are extremely important for nursing, and transitions are always related to these two concepts . Nursing often involves clients and their families in various types of transitions and determines the changes that transitions create in the lives of clients and their families and the nursing care needs, and plans and implements the necessary interventions. Therefore, transition theory generally emerges as a theory that systematically and comprehensively displays nursing phenomena related to transitions . When transitions are related to health or illness or when the responses to the transition are related to health-related behaviors, these transitions fall within the scope of nursing . Nurses tend to be caregivers who prepare their clients for upcoming transitions and teach them coping mechanisms that facilitate the process of learning new skills related to their health and illness experiences. In transition theory, four types of transitions have been defined, based on the experiences of nurses working with patients and their families: developmental, situational, health-illness, and institutional. Health-disease transitions include sudden changes that cause sudden or gradual transitions from a state of wellness to a state of illness, or from a state of illness to a state of health . Early assessment of process indicators in transitions that facilitate health or increase vulnerability is necessary for the development of interventions that facilitate healthy outcomes . In a study conducted in our country on individuals newly diagnosed with diabetes using the transition theory, it was determined that there was a significant increase in patients' self-management and adaptation to the disease . In another study conducted based on the transition theory to increase the quality of life in menopause, it was determined that the quality of life increased . In another study using the transition theory, it was determined that the quality of care during discharge increased, and health care costs decreased with fewer readmissions. In another study conducted on elderly individuals with cognitive impairment, it was determined that the cost of the Transition Care Model was low . No randomized controlled study has been found in the literature using education and digital monitoring based on Meleis's transition theory in improving the quality of life and compliance with lifestyle changes in patients who have had an MI. This research was planned with the idea that the approach developed based on Meleis's Transition Theory could facilitate the illness-health transition process in patients, increase their healthy behavioral gains, increase the quality of care, reduce rehospitalizations, reduce the mortality rate due to MI, and contribute to the nursing literature.
