Glossary Term

Patient-years

This term is synonymous with life-years and refers to the total number of years lived by a group of people. It is sometimes used in rate calculations. For example, if 100 candidates each spent one year waiting for a transplant during a specified period and 50 were transplanted, the transplant rate for this group would be 50 transplants per 100 patient-years on the waiting list.
