Kidney function, future health costs, and quality-adjusted life-years in kidney transplant recipients transplanted during the SARS-Cov-2 lockdown in Denmark - an observational study.

Background It is unknown whether lockdown due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may affect both clinical outcome in kidney transplant recipients and health care economics in Denmark. Methods We compared kidney transplant data at a tertiary university hospital before and during the lockdown period from March 13, 2020 until March 31, 2021, as well as kidney transplant data from Scandiatransplant for entire Denmark. Outcome variables included fall of plasma creatinine during the first postoperative day, and graft function three months posttransplant. We calculated the quality-adjusted life-years (QALYs) and costs which were caused by the lockdown recommendations. Findings The portion of living donation kidney transplantation was largely reduced during the lockdown period compared to before the lockdown: AB0-incompatible living donation declined from 14% to 7% (P<0.01), and AB0-compatible living donation declined from 34% to 20% (p<0.01).In entire Denmark during the lockdown period 78 living donor kidney transplants out of 268 kidney transplants (29%) were performed, whereas there were 878 living donor kidney transplants out of 2218 kidney transplants (39%) before the lockdown (P=0.01).The observed reduction of living donor kidney transplants and consecutive reduction of graft survival will cause a loss of 5.04 QALYs.The additional costs in kidney transplant recipients who received a kidney transplant during the lockdown period will be 277,298 EUR. Interpretation SARS-CoV-2 lockdown period largely reduced living donation kidney transplants which will lead to reduced QALY as well as higher costs in kidney transplant recipients.
