Sumario:OBJECTIVES: To evaluate the impact of the COVID-19 pandemic on solid organ transplantation. BACKGROUND: COVID-19 caused unprecedented disruption to solid organ transplantation (kidney, liver, heart, lung). Concerns about safety and decreases in deceased donors due to pandemic lockdowns have been described as potential causes. METHODS: We report population-based rates of transplantation during the first 3 waves of COVID-19 in Ontario, Canada (March 1, 2020–July 3, 2021) versus a pre-COVID-19 baseline period (January 1, 2017–February 29, 2020). Poisson models were used to predict transplantation rates during COVID-19, based on pre-COVID-19 rates, and generate observed to expected rate ratios (RRs). Ninety-day transplant outcomes (mortality, retransplantation, transplant nephrectomy) were captured. RESULTS: A 34.4% decrease (RR, 0.656; 95% confidence interval [CI], 0.586–0.734) in transplant rates was observed, coinciding with wave 1 and the deployment of a provincial transplant triaging system. Transplants decreased by 14.6% in wave 2 (RR, 0.854; 95% CI, 0.770–0.947) and 23.1% in wave 3 (RR, 0.769; 95% CI, 0.690–0.857) despite the triaging system not being activated. Overall, there was a 24.3% decrease (RR, 0.757; 95% CI, 0.679–0.844) in transplant rates, equivalent to 409 fewer transplants. No sustained changes were observed in heart or liver but sustained and large decreases were seen for lung (RR, 0.664; 95% CI, 0.482–0.915) and kidney (RR, 0.721; 95% CI, 0.602–0.863) transplantation. A low prevalence (1.7%) of COVID-19 infection within 90 days of transplantation was seen. No differences were observed in other 90-day outcomes. CONCLUSIONS: Early safety concerns limited transplantation to immediate life-saving procedures; however, the reductions in kidney and lung transplants continued for the rest of the pandemic, where no restrictions were in place.
