Clinical decision-making in kidney transplant (KT) during the coronavirus disease
2019 (COVID-19) pandemic is understandably a conundrum: both candidates and
recipients may face increased acquisition risks and case fatality rates (CFRs).
Given our poor understanding of these risks, many centers have paused or reduced
KT activity, yet data to inform such decisions are lacking. To quantify the
benefit/harm of KT in this context, we conducted a simulation study of
immediate-KT vs delay-until-after-pandemic for different patient phenotypes under
a variety of potential COVID-19 scenarios. A calculator was implemented
(http://www.transplantmodels.com/covid_sim), and machine learning approaches were
used to evaluate the important aspects of our modeling. Characteristics of the
pandemic (acquisition risk, CFR) and length of delay (length of pandemic,
waitlist priority when modeling deceased donor KT) had greatest influence on
benefit/harm. In most scenarios of COVID-19 dynamics and patient characteristics,
immediate KT provided survival benefit; KT only began showing evidence of harm in
scenarios where CFRs were substantially higher for KT recipients (eg, ?50%
fatality) than for waitlist registrants. Our simulations suggest that KT could be
beneficial in many centers if local resources allow, and our calculator can help
identify patients who would benefit most. Furthermore, as the pandemic evolves,
our calculator can update these predictions.
