Transplantation in Canada: report of the Canadian Organ Replacement Register.
The solid organ transplant rate in Canada grew from 49.5 per million population (PMP) in 1993 to 56.8 PMP in 2002, with a peak rate of 61.0 in 2000. Most of this increase was seen in living donor kidney, liver, and lung transplants where combined rates rose twofold, from 124.9 per 1000 transplants to 243.5. Despite this, the rate of organ transplantation in the United States was 150% that of Canada in 2002. As of December 31, 2002, there were 3,956 patients waiting for an organ transplant in Canada, an 84% increase in the total number of patients on the waiting list as of December 31, 1993, 10 years ago. Cadaveric organ donation did not change over this period. An international comparison of cadaveric organ donation rates for 2001 place Canada (13.5 PMP) well below Spain (32.5 PMP) and the United States (22.6 PMP) but above Australia (9.3 PMP). As a result the annual gap between transplants performed and the waiting list has grown from 927 in 1992 to 2230 in 2001, representing an annual increase of 8.3%.
