It relies on few, readily available, objective variables.The points where MELD definitely edges over Child-Pugh score are. Laboratory to laboratory variations in albumin and prothrombin values.Example- a serum albumin value of 2.8 versus 1.5 will be highly varied clinically but it is rewarded the same point on Child-Pugh. Not only do these criterias vary with observers but also they may be affected by interventions like diuretics etc. Its based on subjective parameters like ascites and encephalopathy.The limitations of Child-Pugh score are as follows. A MELD-Na calculator, which incorporates serum sodium into the model.This calculator is based upon the first published MELD score, thus the etiology of liver disease is required for the calculation A MELD score calculator for predicting postoperative mortality risk in patients with cirrhosis.A MELD score calculator to predict 90-day mortality in patients with alcoholic hepatitis.These are not used for allocation purposes while considering liver transplantation. Hence, they could have negative values to positive infinity. The first MELD score does not use upper or lower limits for laboratory values.It is used while setting priority for allocating deceased donor organs for liver transplantation. The above mentioned UNOS MELD score has laboratory values of INR, total bilirubin and serum creatinine that are In interpreting the MELD Score in hospitalized patients, the 3 month mortality is: Ī variety of calculators which are specific to a particular clinical scenerio are as follows. if bilirubin is 0.8, a value of 1.0 is used). Any value less than one is given a value of 1 (i.e.If the patient has been dialyzed twice within the last 7 days, then the value for serum creatinine used should be 4.0.All values higher than 40 are given a score of 40 The maximum score given for MELD is 40.Laboratory values less than 1.0 are set to 1.0 for the purposes of the MELD score calculation. Multiply the score by 10 and round to the nearest whole number. The MELD score is calculated using the following formula The MELD (Model for End Stage Liver Disease) is a more objective prognostic score, requiring however a calculation software. The MELD Calculator is used for candidates who are 12 years and older. The MELD score calculation uses-įor candidates on dialysis, defined as having 2 or more dialysis treatments within the prior week or candidates who have received 24 hours of CVVHD (Continuous Veno-venous Hemodialysis) within the prior week, will have their serum creatinine level automatically set to 4.0 mg/dl. The MELD/PELD Calculator uses the specific formulas approved by the OPTN/UNOS Board of Directors and used for the allocation of livers by the OPTN match system. The MELD Calculator is a utility that allows you to enter hypothetical or actual parameters and calculate a MELD score for an individual patient. The Model for End-Stage Liver Disease (MELD) score has been used by the Organ Procurement and Transplantation Network (OPTN) since February 2002 as the basis for allocation of deceased donor livers for transplantation among adults in the United States. A number of modification have been made by UNOS (United Network for Organ Sharing) to the model for its implementation in organ allocation for liver transplantation. It was initially described by Kamath et al in 2001 and modified by Wiesner et al, also in 2001. The original version of the MELD scale as developed by investigators at Mayo Clinic. This model was derived from a heterogeneous group of patients at 4 medical centers in the United States and validated in an independent data set from the Netherlands. It is more recent than the Child-Pugh score. In other words under the MELD scoring system - the sickest patient gets the liver transplant. The equation seeks to calculate a patient’s likelihood of dying within three months from their liver disease. The new system, known as the Model for End-Stage Liver Disease (MELD) score, leaves no room for subjective criteria favoritism or hospital-shopping, as it is based on a mathematical equation. It is used as a disease severity index to help prioritize allocation of organs for transplant. The Model for End-Stage Liver Disease (MELD) is a reliable measure of mortality risk in patients with end-stage liver disease. Associate Editor-In-Chief: Suvekchha Devkota Shankar Kumar, M.B.B.S.
