Method for classifying corneal donor selection algorithms

Proven COVID-19 history0=no exclusion
1=perform PCR systematically (no exclusion if negative), no delay
2=no exclusion if symptom-free for less than 14 days
3=no exclusion if symptom-free for more than 14 days
4=systematic exclusion
Suspected COVID-190=no exclusion
1=perform PCR systematically (no exclusion if negative)
2=no exclusion if symptom-free for 14 days
3=no-exclusion if symptom-free for more than 14 days
4=systematic exclusion
Asymptomatic at risk0=no exclusion
1=perform PCR systematically (no exclusion if negative)
2=no exclusion if contact-free for 14 days
3=no exclusion if contact-free for more than 14 days
4=systematic exclusion
Postmortem PCR on a nasopharyngeal swab0=not mandatory or only recommended or used to test donors at risk or suspected
1=mandatory for all donors
Antemortem PCR0=allowed
1=not allowed or not mentioned
  • Higher scores are more likely to reduce the number of eligible donors.
