Open label single-centre randomised controlled interventional trial. All infants with congenital heart disease (CHD) and age <28 days admitted to the neonatal and paediatric intensive care unit at the University Children's Hospital in Zurich are eligible. Infants will be allocated 1:1 to creative music therapy (CMT) and standard care using block randomization with stratification by socio-economic score (SES, <8 vs >8) and risk of CHD according to the Risk Stratification for Congenital Heart Surgery (RACHS-2). CMT will be conducted 3x/week with a minimum of ten sessions. The primary outcome is mother-infant interaction at age 6 months assessed using a video of a feeding interaction at home, coded in a blinded manner with the Parent-Child Early Relational Assessment.
In the context of a clinical trial, the investigators will evaluate if parent-infant interaction can be improved by a family integrated, individualised, interactive resource- and needs-oriented music therapy approach in the dyads of infants with congenital heart disease and their parents.~This intervention will be compared with the standard of care. Infants allocated to the control group will receive standard care during admission. Standard care includes involvement of a multi-professional team consisting of medical and nursing team, psychologists/psychiatrists, social workers, breastfeeding counsellor, speech therapist, nutritional counsellor and physiotherapists.
