In 2008, my colleague Ray Kim published the. Two back up caregivers are also needed. Related Media. We termed the resulting prog-nostic index MELD-XI (for MELD excluding INR). Serum sodium values are input in mEq/L and then normal range is considered between 125 and 137 mEq/L. The term MELD stands for "model for end-stage liver disease. Stratifies severity of end-stage liver disease, for transplant planning. Please enter the value for INR, bilirubin and creatinine in the corresponding boxes. 6. MDCalc loves calculator creators – researchers who, through intelligent and often complex methods, discover tools that describe scientific facts that can then be applied in practice. To as-sess the predictive accuracy of this new prognostic index, TABLE 1. It is preferable to using the calculator to calculate the MELD as there are several caveats relating to minimum and maximum values assigned in the MELD. Role of MELD Score and Serum Creatinine as Prognostic Tools for the Development of Acute Kidney Injury after Liver Transplantation. It’s based on different kinds of lab tests. In some cases there may be special circumstances such as certain liver cancers that are not taken into account during your score calculation.

The MELD score components – bilirubin, creatinine, and INR – as well as serum sodium, were the predictor variables. S The original MELD score is a prospectively developed and validated chronic liver disease severity scoring system that uses a patient's laboratory values for serum bilirubin, serum creatinine, and the international normalized ratio (INR) for prothrombin time to predict three-month survival ( original MELD score ). A formula is then used to calculate the score and three-month mortality can then be predicted (as seen below). The score has prognostic value in terms of three month mortality and certain complications. The synthetic function of the liver is assessed through the INR, which reflects the ability of the liver to produce coagulation factors.
