Abstract
BACKGROUND: Each year, children die awaiting LT as the demand for grafts exceeds the available supply. Candidates with public health insurance are significantly less likely to undergo both deceased donor LT and D-LLD LT. ND-LLD is another option to gain access to a graft. The aim of this study was to evaluate if recipient insurance type is associated with likelihood of D-LLD versus ND-LLD LT. METHODS: The SRTR/OPTN database was reviewed for pediatric LDLT performed between January 1, 2014 (Medicaid expansion era) and December 31, 2019 at centers that performed ≥1 ND-LLD LDLT during the study period. A multivariable logistic regression was performed to assess relationship between type of living donor (directed vs. non-directed) and recipient insurance. RESULTS: Of 299 pediatric LDLT, 46 (15%) were from ND-LLD performed at 18 transplant centers. Fifty-nine percent of ND-LLD recipients had public insurance in comparison to 40% of D-LLD recipients (p = .02). Public insurance was associated with greater odds of ND-LLD in comparison to D-LLD upon multivariable logistic regression (OR 2.37, 95% CI 1.23-4.58, p = .01). CONCLUSIONS: ND-LLD allows additional children to receive LTs and may help address some of the socioeconomic disparity in pediatric LDLT, but currently account for only a minority of LDLT and are only performed at a few institutions. Initiatives to improve access to both D-LLD and ND-LLD transplants are needed.
