Quality evaluation of solid organ transplant in Italy for the period 2000 to 2002 data from the national transplant center.

BACKGROUND: As part of the increased need for transparency and disclosure of information in health care, the Italian Minister of Health has commissioned the Superior Institute of Health to study health outcomes for several procedures, among which is solid organ transplants. We herein report the results of a quality evaluation of solid organ transplants and on the relationship between hospital volume of activity and outcomes, using the data routinely collected by the National Transplant Center during the period 2000 to 2002. METHODS: We collected and analyzed all the information on solid organ transplants between 2000 and 2002, along with clinical information before and after transplant. Multivariate survival analysis was performed to adjust the follow-up data for the complexity of the cases. Correlation graphs are presented that assess the association between the number of transplants and the adjusted 1-year survival of both the organ and the patient. RESULTS: One-year survival was 92.4% for kidney, 77.8% for liver, and 83.9% for heart. Patient survival was 97.0%, 84.1%, and 83.9%, respectively. A negative correlation was observed between the number of transplants performed by each center and 1-year survival of the organ. CONCLUSIONS: Our study indicated that survival after organ transplants in Italy is good and that hospital quality, indirectly measured through survival, overlaps that observed in other Western countries.

Molecular monitoring of organ recipients from cancer-affected donors by detection of circulating tumor cells.

We have initiated regular molecular monitoring based on nested RT-PCR detection of circulating tumor cells for monitoring recipients of organs from cancer-affected donors in Italy (in the context of a "Donation Safety and Donated Organ Quality" project organized by the Centro Nazionale Trapianti). Five patients are being monitored. For two patients who each received a kidney from a single donor with prostate adenocarcinoma, RT-PCR was performed using PSA mRNA. For three recipients of organs (two livers and one kidney) from donors with renal cell carcinoma, RT-PCR was performed using cytokeratine 18 and 19 mRNA. Blood samples from five healthy subjects were used as negative controls. After a median monitoring time of 26 months (range 8 to 32), none of the regular 3-month assays has tested positive. This pilot study suggests that detection of circulating tumor cells by nested RT-PCR may provide a feasible molecular monitoring, which might assist decision making regarding other forms of clinical surveillance.

Optimizing the organ procurement process: organizational prerequisites and monitoring strategies in a national network.

The current project sought to collect detailed information on the Italian donation system and in particular on the organization and functioning of the local coordinating centers. The final objective was to provide local and regional institutions with the information required to improve the system. While improving the knowledge of current Italian donation system, the project had constructive purposes. Our intention was to analyze how the national system is working, what the coordinating centers are actually doing, how they are organized, to what extent existing rules are obeyed, and what are the main limits of the system. This analysis sought to lead to the development of a set of proposals that can be summarized in two categories: (1) "intrinsic" actions, that is, those established and implemented at the hospital level; and (2) supporting "extrinsic" actions, that is, those identified by the National Transplant Centre and addressed to the regional and interregional coordinating networks. Finally, the analysis of the application of the existing rules should lead to the development of practice guidelines such that each center conforms to the existing regulations established by European directives.

[Kidney transplantation in Italy: an evolving scenario].

BACKGROUND: Italian transplantation systems have dramatically improved in the last decade. Kidney transplantations are now strictly monitored and excellent results has been achieved in terms of quality and the ability to reduce waiting times for receiving transplantation. METHODS: The Italian organizational retrieval and transplant system is articulated on four levels: local, regional, inter-regional and national. The Italian Transplant Information System (SIT) was set up in 2000 in accordance with Law 91/99. Patient data on the waiting lists and follow-up of transplanted patients are routinely collected. RESULTS: A total of 4406 kidney transplants have been carried out in the 40 Italian kidney transplant centers in 2001-2003. The survival analysis was conducted for the 2000-2002 in 4222 cases. Overall 1-yr survival was 92.4% for the graft and 97% for the patients. After adjusting for variables independently associated with the outcome at multivariate analysis (for example, the case-mix), patient and graft survival at 1 yr was 98.1% and 93.8%, respectively. No remarkable differences in 1-yr graft survival were observed between the 40 Italian kidney transplant centers. At multivariate analysis, variables independently associated with graft failure were donor age, degree of HLA mismatch and recipient case-mix. Analysis of the waiting list showed approximately 6500 patients waiting for kidney transplantation. The mean waiting time was 3.04 yrs, with a mortality rate of 1.18% per year. CONCLUSIONS: Kidney transplantation activity in Italy has produced excellent results in terms of quality and number of transplants per year. However, the number of patients on the waiting list and the waiting time call for further action to increase the number of available organs.
