Nationwide Survey on Transitional Care for Patients With Childhood-Onset Cardiomyopathy in Japan.

Individuals transitioning into adulthood require age-appropriate medical care and delegation of decision-making authority from their parents to the patients themselves. Although there have been multiple observational and interventional studies on transitional care for patients with congenital heart disease (CHD) in the cardiovascular field, transitional care specific to childhood-onset cardiomyopathy (CM) remains unaddressed. A nationwide questionnaire-based survey was performed in the pediatric cardiology departments of 151 facilities in Japan. Responses were obtained from 100 (66%) facilities with low transfer rates (<5%) for childhood-onset CM cases. The comparison between CHD-transferring and non-CHD-transferring facilities revealed a significantly higher transfer rate (83.9%) for childhood-onset CM cases in the CHD-transferring facilities (P<0.001). Regarding the transition programs, 72 (72%) facilities do not offer any programs for CM, while most (92%) facilities recognize its necessity. Finally, only 19 (19%) facilities provided a transition program, 10 of which were CHD based. To the best of our knowledge, this is the first study to demonstrate the poor transition/transfer care status of patients with childhood-onset CM in Japan. The transfer rate of CMs was lower than that of CHDs, and transition programs were less available. Referring to the system established for CHD could help develop a successful transitional care system for CM.
