Pediatric intestine transplant cost: Analysis of the Pediatric Health Information System database.

BACKGROUND: We aimed to evaluate costs from transplant to discharge in children who had undergone intestine transplant. METHODS: We performed a cross-sectional observational study of pediatric intestine transplant recipients from 2004 through 2020, utilizing the Pediatric Health Information System database. Standardized costs were applied to all charges and converted to 2021 US dollars. We analyzed the association of cost from transplant to discharge with age, sex, race and ethnicity, length of stay, insurance type, transplant year, short bowel syndrome diagnosis, liver-containing graft, hospitalization status, and immunosuppressive regimen. Predictors with a P value <0.20 in univariable analysis were included in a multivariable model, which was reduced using backwards selection with a P value of 0.05. RESULTS: We identified 376 intestinal transplant recipients across nine centers (median age, 2 years; 44% female). Most patients had short bowel syndrome (294; 78%). The liver was included in 218 transplants (58%). Median posttransplant cost was $263,724 (interquartile range [IQR], $179,564-$384,147), and length of stay was 51.5 days (IQR, 34-77). In the final model, increased cost from transplant to hospital discharge was associated with liver-containing graft (+$31,805; P = 0.028), T-cell-depleting antibody use (+$77,004; P < 0.001), and mycophenolate mofetil use (+$50,514; P = 0.012) while controlling for insurance type and length of stay. A 60-day posttransplant hospital stay would cost an estimated $272,533. CONCLUSIONS: Intestine transplant has high immediate cost and long length of stay that varies by center, graft type, and immunosuppression regimen. Future work will examine the cost-effectiveness of various management strategies before and after transplant.
