Observed and Expected Survival Rates After Transplant Surgery
These tables show two types of outcomes after a transplant. These are called "observed" and "expected" survival rates.
What is an observed survival rate?
This number is the actual percentage of patients or organs that we transplanted successfully. If the observed survival rate is higher than the expected survival rate, that indicates that our center is performing better than the national forecast.
What is an expected survival rate?
This number shows how successful our transplants are supposed to be, based on a calculation from the national organ registry. This calculation takes into account how sick our patients are, how many patients we have and other characteristics of our Transplant Center, such as type of facilities and number of specialists. If we do not show an expected survival rate on any table, that means there haven't been enough cases — either at our center or in the United States — for the national organ registry to calculate a reliable rate.
The tables show survival rates for both pediatric and adult patients. Pediatric patients are 17 years old or younger; adult patients are 18 years old or older.
