In view of growing disproportion between the number of organ donors and recipients awaiting transplantation the issue of an appropriate allocation of organs is becoming more and more important. The Child-Turcotte-Pugh Scale (CTP), which has been used for many years, has proved limited in many aspects. Hence, MELD Score (Model for End-Stage Liver Disease) was first introduced in the US in 2002 and later on in numerous other countries. This has led to a decrease in mortality among patients waiting for a liver transplant. Research into constructing new prognostic scales or improving the old ones are being continued. Various modifications of both MELD and CTP score have been evaluated. In this article we review recently tested scores and discuss their potential applications.
