Scandiatransplant: thirty years of cooperation in organ transplantation in the Nordic countries.

The Nordic organ exchange organization, Scandiatransplant was established in 1969. The organization, which covers a population of 23.9 million inhabitants, includes all 11 organ transplant centers in the 5 Nordic countries Denmark, Finland, Iceland, Norway and Sweden. The economy is solely based on transplant center fees. All Nordic patients waiting for an organ transplant are registered on one common waiting list. Rules for the exchange of organs are settled by unanimous decision, and the compliance to the rules is excellent. Kidney exchange is based on HLA matching, whereas the exchange of livers and hearts is based on clinical urgency. In 1997, 43% of the liver transplantations in Scandiatransplant were performed with an exchanged organ and the exchange rate for kidneys was 20%. Currently, the Scandiatransplant waiting list includes 1,538 patients waiting for a kidney transplant, 20 patients are waiting for a liver, 37 for a heart, and 156 patients are waiting for a lung transplant. The organ donation rate in Scandiatransplant has declined in recent years, from 16.0 per million population (PMP) in 1993 to a level of 13.5 PMP in 1997. The number of kidney transplants has varied between 800-900 per year during the past 10 years, corresponding to 33-38 transplants PMP. Approximately 30% of the renal transplants were performed with kidneys from living donors. The liver transplantation activity was approximately 7 PMP per year. Heart transplantation was performed at a rate of 4-5 PMP per year, and lung transplants at 4 PMP per year.
