Higher probabilities are desirable.
Cumulative probability of a transplanted organ (first kidney, liver, lung or heart) continuing to function at 1 year, 3 years and 5 years after transplantation based on Kaplan-Meier survival analysis. Survival analysis considers time at risk for graft failure to be the time between transplantation and graft failure, death or censoring at either loss to follow-up or the end of the study period.
Unit of analysis: Transplanted organ
Note that bilateral kidney or lung transplants are counted only once toward this indicator.
The following are included:
- Age 18 or older
- Transplantation of a kidney, liver, heart or lung
Definition of organ transplantation
- Kidney: Canadian Organ Replacement Register (CORR) organ type code beginning with 1
- Liver: CORR organ type code beginning with 2
- Heart: CORR organ type code 30
- Lung: CORR organ type code beginning with 4
The following are excluded:
- Out-of-country transplants (CORR facility code 88888)
- Organ retransplantation (graft number is greater than 1)
- Transplantation of several organ types in 1 surgery (records for multiple organ types for 1 surgery, or organ type code 43 or 90)
- For liver or lung recipients, transplantations from a living donor (donor type code is not 01)
Censor date
The censor date is the last day of follow-up. If a patient’s post-transplant care is reported to be transferred from the facility of their transplant surgery, that date of transfer is considered the censor date.
Failure date
The date of the first of the following events as reported in CORR is considered the failure date:
- Patient death
- Graft failure

Comments
Future reporting will use data from the new Canadian Organ Donation and Transplantation Data System (CanODT) once it is available.
