Cognitive function and behavioural status in paediatric heart and heart-lung transplant recipients: the Harefield experience.
OBJECTIVE: To assess the psychological impact of cardiac and cardiopulmonary transplantation on children. DESIGN: Retrospective cross sectional study. SETTING: One British centre performing paediatric heart and heart-lung transplant operations, four cardiac units in London, three London schools, two London health centres, and the dental department of a London children's hospital. SUBJECTS: 65 children who had been given heart or heart-lung transplants and two reference groups of 52 children who had had other types of cardiac surgery and 45 healthy children. MAIN OUTCOME MEASURES: Development, cognition, and behaviour at home and at school as assessed by measures with proved validity and reliability. RESULTS: Developmental and cognitive measures indicated that children given transplants had significantly lower scores on several parameters, particularly in terms of development in children under 4 1/2 years of age. Performance on all tests, however, was within the normal range. There were no significant differences in behavioural ratings between the transplant and reference groups, though problem behaviour at home was more prevalent in the transplant group. CONCLUSIONS: Though cognitive development may be within the normal range, there are adverse psychological effects associated with cardiac and cardiopulmonary transplantation. These data indicate the need for a controlled prospective study in which children and their families are seen before and at regular intervals after transplantation. Interventions should be developed that are tailored to the particular needs of this very specialised group of paediatric patients and their families.
