BackgroundPatients with congenital heart disease are at risk of motor, cognitive, speech, and feeding difficulties after cardiac surgery. Rehabilitation therapy could improve functional outcomes in this population if applied in the acute postcardiac surgical in‐hospital stay. However, information on the types of acute postcardiac surgery therapy needs in children is scarce. Our goal was to describe rehabilitation therapy following congenital heart surgery and pre/intraoperative factors associated with need for therapy.Methods and ResultsThis is a retrospective cohort study of patients <18 years undergoing heart surgery at our center from January 1, 2013 to January 31, 2015. Demographic, and pre‐, intra‐, and postoperative clinical and rehabilitation therapy (physical, occupational, speech, feeding therapy, and neurodevelopment intervention) data were collected. Need for rehabilitation therapy in the acute postoperative period, particularly following palliative repair, was the outcome variable in a multivariable logistic regression model to identify independent pre‐ and intraoperative factors associated with therapy. A total of 586 out of 1415 (41%) subjects received rehabilitation therapy postsurgery. Certain subgroups had increased rehabilitation therapy use such as neonates (80%). On multivariable analysis, palliative repair, prematurity, genetic syndrome, presurgical hospital stay of more than 1 day, and prolonged cardiopulmonary bypass time were independently associated with rehabilitation therapy.ConclusionsNearly half of patients who underwent post–congenital heart surgery received rehabilitation therapy. Frequency of use and types of therapy vary according to patient characteristics; however, certain pre‐ and intraoperative factors are associated with need for rehabilitation therapy, and may aid decision‐making for appropriate resource allocation.
