Higher probabilities are desirable.
Cumulative patient survival at 1 year, 3 years and 5 years after transplantation based on Kaplan-Meier survival analysis. Survival analysis considers eligible patients’ time at risk for death as the time between transplantation and patient death or censoring at either loss to follow-up or the end of the study period.
Unit of analysis: Patient
Note that only patients with a first kidney, liver, lung or heart transplantation are included.
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 kidney, 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 failure date is the date of the patient’s death as reported in CORR.

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