Background. The Organizzazione Centro-Sud Trapianti (OCST), which was created in 1998, is organized into eight regional areas, each referring to a local Regional Transplant Coordinating Center. Organs are primarily allocated to meet the demands of transplant C, centers in each regional area. Urgencies, pediatric grafts, and paybacks are managed by an Interregional Transplant Coordinating Center. The aim of the current work is to report on the impact of introduction of OCST on organ donation and transplant activity over the period from 1999 to 2002. Materials and methods. A retrospective analysis of donor and transplant data charts over the period from 1999 to 2002 focused on outcome analysis based on donor epidemiological data, cause of death, reasons for discards and grafts performed at OCST local transplant centers. Results. From 1999 to 2002, we observed a remarkable increase in organ donation from 8.8 to 22.5 donors per million people. Donor epidemiology showed an increase in median a(ye and stroke incidence rates and a decrease in trauma cases. The nonharvested donor rate rose steadily over the study period, plateauing at 58%, which was compensated for by a threefold increase in donation. Family oppositions ranged as high as 35.5% on average, despite public efforts to support donation. Transplant activity rose by 76%. Conclusions. The institution of OCST and the efforts from central and regional authorities have yielded a significant increase in organ donation and transplant activity rates over the period from 1999 to 2002. Major areas of concern are the high opposition rate and the decreasing quality of harvested grafts. Long-term analysis is underway to assess the impact of OCST on the quality of transplants performed in the catchment area
