Patient Survival Following Organ Transplant

The probability of a patient surviving at various time points following organ transplantation

Higher probabilities are desirable.

Calculation

Cumulative patient survival at 90 days, 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:

  1. Age 18 or older 
  2. Transplantation of a kidney, liver, heart or lung

Definition of organ transplantation

  1. Kidney: Canadian Organ Replacement Register (CORR) organ type code beginning with 1
  2. Liver: CORR organ type code beginning with 2
  3. Heart: CORR organ type code 30
  4. Lung: CORR organ type code beginning with 4

The following are excluded:

  1. Out-of-country transplants (CORR facility code 88888) 
  2. Organ retransplantation (graft number is greater than 1)
  3. Transplantation of several organ types in 1 surgery (records for multiple organ types for 1 surgery, or organ type code 43 or 90)
  4. 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.

Patient Survival Following Organ Transplant

Short/Other Names

Patient Survival

Description

The probability of a patient surviving at various time points following organ transplantation

Rationale

Organ transplantation is a life-saving therapy that restores organ function following organ failure. Patient survival following transplantation is a key outcome of the transplantation system.

Interpretation

Higher probabilities are desirable. 

HSP Framework Dimension

Health system outcomes: Improve health status of Canadians

Caveats and Limitations

Note that the methodology for this indicator varies slightly from the patient survival methodology in CORR reports. Notably, CORR’s methodology censors follow-up at re-transplantation. Use caution when comparing results across products.

Comments

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