*Purpose: The implementation of virtual crossmatching (VXM) into conventional protocols may reduce expenditures associated with organ allocation.
*Methods: A single center retrospective analysis of the total number of physical crossmatches (FCXM) performed for deceased donor kidneys between October 1st 2016 to September 30th 2017 (before VXM) was compared to the total number performed from January 1st 2018 to December 31st, 2018 (after VXM implementation) and extrapolated to all kidney transplants performed nationally. Wilcoxon Rank Sum Test was used to compare the pre-VXM and post-VXM sample periods.
*Results: 64 patients were transplanted with deceased donor kidneys between October 1st 2016 to September 31st 2017 and 64 were transplanted from January 1st 2018 to December 31st 2018. Starting in October 2017, our center began to utilize a VXM screening protocol prior to kidney transplantation reserving FCXM for highly sensitized patients and retrospectively after transplant. The demographics of the two groups were compared and there was no significant difference in age, race, sex, or CPRA. There was a significant difference in KDPI between the pre-VXM and post-VXM groups. A Wilcoxon Rank Sum Test indicated a statistically significant reduction in FCXMs in the year following implementation of VXM screening than the year prior. At our center, the billing charge of FCXM is $2200. The billing charge of VXM is $115. This equates to a cost-savings of $2085 per flow cytometric crossmatch that is deferred per each VXM. This led to a cost savings of over $75,000 in the study period. Based on the national OPTN report for 2018, there were 9,867 deceased kidney donors which resulted in 14,725 transplants. If every center in the nation adopted a standardized virtual crossmatch protocol, we estimate roughly $17,806,943 in savings annually.
*Conclusions: Implementation of a VXM screening protocol reduces the total amount of FCXMs performed on deceased donor kidney transplants, and thus confers a cost savings to both the individual transplant center and the total cost of healthcare nationally. We believe that adoption of standardized VXM screening protocols can reduce healthcare-related expenditures at a nationwide level and should become an economic mandate.
