With the limited capacity of the available donor pool and the simultaneously growing demand for heart transplantation, expanding the heart donor selection criteria as one of the ways of increasing the availability of organ transplantation, and particularly donor heart, has become a challenge. On one hand, the use of expanded criteria donors increases the number of transplants and reduces the time spent on the waiting list. On the other hand, however, it increases the risk of adverse transplant outcomes. Accordingly, high-risk donors require a more thorough objective assessment using predictive models, while organs obtained from expanded criteria donors, require optimal selection of a donor-recipient pair. Analysis of global and national studies presented in this review reveals the depth of the current problem of heart donor selection.

ObjectivesTo assess to which extent the COVID-19 pandemic affected corneal transplantation by virtue of donor selection algorithms in different European countries.DesignSurvey.Setting110 eye banks in 26 European countries.Participants64 eye banks covering 95% of European corneal transplantation activity.InterventionsA questionnaire listing the number of corneas procured and distributed from February to May 2018–2020 was circulated to eye banks.Main outcome measuresThe primary outcome was the number of corneal procurements. Additional outcomes were national algorithms for donor selection, classified according to their stringency (donors with COVID-19 history, suspected for COVID-19, asymptomatic, PCR testing) and the pandemic severity in each country. We calculated Spearman’s correlation coefficient to determine, two by two, the relationship between the 3-month decline in eye banking activity (procurement), the stringency of donor selection algorithm and the grading of pandemic severity (cases and deaths). A partial correlation was run to determine the relationship between decline and stringency while controlling for pandemic severity.ResultsProcurements decreased by 38%, 68% and 41%, respectively, in March, April and May 2020 compared with the mean of the previous 2 years, while grafts decreased, respectively, by 28%, 68% and 56% corresponding to 3866 untreated patients in 3 months. Significant disparities between countries and the decrease in activity correlated with stringency in donor selection independent of pandemic severity.ConclusionsOur data demonstrate significant differences between countries regarding donor screening algorithms based on precautionary principles and, consequently, a decrease in the donor pool, already constrained by a long list of contraindications. Fundamental studies are needed to determine the risk of SARS-CoV-2 transmission by corneal transplantation and guide evidence-based recommendations for donor selection to justify their substantial medical and economic impact.
