Comparison of transplant listing strategy in two renal dialysis centers within a regional transplant alliance.
OBJECTIVE
An increasing dialysis population and insufficient supply of transplant organs necessitate that patients are carefully evaluated prior to registration on the national waiting list to ensure effective utilization of a scarce resource. We have assessed listing practice in two renal units within the North of England Transplant Alliance.


METHODS
Demographic, ethnic and clinical data were recorded at initiation of dialysis for patients from two northern English cities, Bradford (n = 209) and Hull (n = 202) between 1994-2000. Patients were stratified by two co-morbidity scoring systems. Multivariate and survival analyses were undertaken by registration status.


RESULTS
Overall, 159 patients were registered onto the waiting list. Stratification by co-morbidity predicted listing at high and low risk, but with overlap at medium scores. There was no difference in overall co-morbid burden between the two centers (p = 0.161 and 0.316, respectively, for two scoring systems). Logistic regression analysis demonstrated a center effect, Hull having an odds ratio for listing of 0.48 compared to Bradford (p = 0.041). Short- and medium-term survival in the listed group was high regardless of co-morbid score (22 vs 174 deaths in the non-listed group). In this cohort, five patients died with grafts, another three died whilst active on the waiting list. The remaining 14 patients had been removed from the list prior to death.


CONCLUSIONS
Co-morbidity scoring schemes are unlikely to be sophisticated enough to accurately identify those who would most benefit from transplantation, and the value of clinical judgment is well-shown in this study. Standardization of registration will result in more equitable allocation of organs. However, this study has demonstrated that there are differences in listing practices even within a single alliance. Continuous assessment will allow judicious removal from the waiting list of patients who have developed an unacceptable co-morbid burden.
