Abstract
Congenital heart defects (CHD), the most frequent congenital malformations, have shown an increased survival and exponential growth of the adolescent and adult population living with CHD. Interventions that optimize the transition of patients from pediatric to adult health care services are essential for ensuring positive long-term outcomes.
Objective: To describe the knowledge and management of this disease, self-efficacy, and quality of life of young people with CHD during the transition period in two hospitals in Santiago, Chile.
Patients and Method: Non-experimental, descriptive, cross-sectional study. Patients completed: a) a survey of socio-demographic data, knowledge and management of their condition, and use of health services; b) the Health-Related Quality of Life (Con-HRQoL) Scale in patients with CHD; and c) the Generalized Self-Efficacy (GSE) Scale.
Results: We obtained a sample of 51 patients, 53% of them were men, and the mean age was 17 ± 2.49 years. The complexity of the CHD was mild in 22%, moderate in 29%, and high in 49%. Although patients reported high self-efficacy and good levels of quality of life, there was a lack of knowledge and self-management of their heart disease.
Conclusions: The study showed that adolescents and young people with CHD are not prepared to achieve a successful transition to adult health care services, and there is a need for the implementation of transition programs focused on education, self-care, and self-management of the disease.
