Article Synopsis
  • * A survey conducted across 151 pediatric cardiology departments in Japan found that only 19% offered transition programs for childhood-onset cardiomyopathy (CM), despite 92% of facilities acknowledging the need for such programs.
  • * The study highlights that transfer rates for childhood-onset CM are significantly lower than for congenital heart disease (CHD), suggesting that adopting CHD care systems could improve the transitional care for CM patients.

Health literacy, which is the ability to find, understand, and use information as well as services to make informed health-related decisions and actions, is essential for ensuring that youths with chronic diseases adapt to and live with their illnesses. However, in Japan, an appropriate approach for measuring health literacy levels among children is yet to be developed. The Health Literacy and Resiliency Scale for Youth (HLRS-Y) was developed by Kathy Bradley-Klug and her colleagues to assess health literacy, resiliency, and self-advocacy/support among youths aged between 13 and 21 years with chronic illnesses in the United States of America (United States).

Disease understanding in patients with congenital heart disease is important in transitional and lifelong care. This study aimed to develop the Japanese version of the Leuven Knowledge Questionnaire for Congenital Heart Disease (LKQCHD) and identify factors associated with disease-related knowledge. After confirming the content and face validity of the scale, a questionnaire including the LKQCHD was distributed to 59 eligible patients aged >16 years attending a university hospital.

Article Synopsis
  • The study examined the care of 230 adult congenital heart disease (ACHD) patients referred to a specialized center, focusing on the differences between referrals from non-congenital heart disease specialists (n-CSDs) and congenital heart disease specialists (CSDs).
  • Patients referred by n-CSDs were generally older and had simpler forms of congenital heart disease compared to those referred by CSDs, and they showed a higher rate of lost follow-ups and a greater need for invasive treatments.
  • The findings highlight that patients with moderate complexity in CHD referred by n-CSDs are more likely to need unexpected invasive procedures, suggesting that these patients benefit significantly from being referred to specialized ACHD centers.

Background: Palliative care service (PCS) has been shown to be utilized less in patients with leukemia and malignant lymphoma than in those with solid tumors. Previous studies have suggested hematologists' limited awareness of PCS as one of the reason for low PCS referral in hematology. However, little is known about such an awareness and potential barriers to collaboration between hematologists and PCS.
