Kidney Transplantation

Many more people need an organ for transplantation than there are organs available. Once a person with end-stage kidney disease has been evaluated and becomes a candidate for a transplant, he or she is put on a waiting list.

How long the wait for a donor kidney is depends on the urgency of the patient's condition, his or her blood and tissue type, the size of organ needed, how long he or she has been on the waiting list and the availability of a suitable organ.

The table below describes the kidney transplant rate at Cedars-Sinai and factors such as the total amount of time that all transplant candidates at Cedars-Sinai spent on the wait list, how many donor organs became available at Cedars-Sinai and how Cedars-Sinai's transplant rate compares with other kidney transplant centers throughout the nation. These data are reported to the  Scientific Registry of Transplant Recipients

* Person years are calculated as days (converted to fractional years). the number of days from the start of the period or from the date of the first waiting listing until death, transplant, removal from the waiting list or the end of the observation period.

** The expected transplant rate is adjusted for age, blood type, previous transplantation, time on the waiting list, peak PRA, and the interaction between previous transplantation and peak PRA.

Patient and Graft Survival Rates for Adult Kidney Transplant Patients at Cedars-Sinai

A successful kidney transplant depends on appropriate evaluation of the kidney recipient, expertise in the surgical procedures required to transplant the kidney and on-going monitoring after transplant to prevent kidney rejection or infections.

At Cedars-Sinai Medical Center, one-month, one-year and three-year survival rates are tracked for transplants patients.

In the table below, both the numbers and percentages of kidney transplant patients surviving one month, one year and three years are highlighted.

In addition, survival rates for kidney transplant patients at Cedars-Sinai Medical Center are also compared to survival rates expected for kidney transplant patients with similar ages and health conditions.

* These statistics reflect patients who had their first kidney transplant. It does not include multiple organ transplants (such as a kidney and pancreas transplant).

** The rate that would be expected for grafts or  patients served by this center, given the characteristic mix of the recipient and donor (age, disease and blood type, etc.) and the experience of similar patients in the United States as a whole.

*** The hazard ratio provides an estimate of how Cedars-Sinai Medical Center (CACS)'s results compare with what was expected based on modeling the transplant outcomes from all U.S. programs. A ratio above 1 indicates higher than expected graft failure or patient death rates  (e.g., a hazard ratio of 1.5 would indicate 50% higher risk), and a ratio below 1 indicates lower than expected graft failure rates (e.g., a hazard ratio of 0.75 would indicate 25% lower risk). If the medical center's graft failure or death rate were precisely the expected rate, the estimated hazard ratio would be 1.0.
