Consequences of Changes in the Liver Allocation System for Transplantation in the Silesian Voivodeship and in the Transplantation Center in Katowice.

BACKGROUND: For a number of years, the system of procured livers for transplantation by transplant centers in a fixed order, regardless of the location of the procurement site, was in force in Poland. In mid-2018, priority was introduced in the collection of livers by a team from a given province. The aim of the study was to evaluate the impact of changing the liver transplantation allocation system at the Katowice Transplant Center (KTW) on the number of transplanted livers and on the selected parameters of donors from which the liver was procured. METHODS: The rates and cold ischemia time (CIT) of procured livers were analyzed. RESULTS: The rate of livers procured by the KTW transplant team increased from 36.6% to 53.3%, and at the same time the rate of livers procured by this team and sent for transplantation in other transplant centers increased. The rate of livers transplanted in the KTW, which were procured in the Silesian Voivodeship, increased from 37.4% to 61.0%, and the rate of livers procured outside the Silesian Voivodeship decreased from 54.8% to 36.4%. The CIT of livers transplanted in the KTW was reduced from 407.5 to 360.0 minutes. The comparative analysis of donor parameters of livers procured by the KTW transplant team and transplanted in Katowice revealed no differences regarding analyzed clinical and biochemical parameters. CONCLUSION: The change in the allocation system increased the number of livers procured by the local team and shortened CIT of livers transplanted at the KTW.
