Abstract

Methods. All transplant units were invited to participate; four agreed to do so, contributing 36 patients awaiting liver transplantation. Blood was collected from these 36 and divided into aliquots then sent to the four participating centres. Every centre measured creatinine and bilirubin for every patient. The results were analysed for the degree of agreement between centres for creatinine and MELD scores using the Bland-Altman method and Wilcoxon rank test. Results. The mean creatinine value varied from 101 mu mol/l in centre C to 110 mu mol/l for the same sample in centre A, with significant differences between the four centres (P < 0.05, Wilcoxon signed-rank test). The MELD scores were significantly different between centre C and all other centres (P < 0.05). Conclusion. This study demonstrates lack of agreement in measurement of serum creatinine and MELD scoring between four UK transplant centres. A difference in two MELD points can have a significant impact on patient outcome, and these factors will have to be addressed if a UK-wide transplant list is to be initiated.
