This means that for every 100 mg/dl (5.5 mmol/L) above a serum glucose level of 100 mg/dl (5.5 mmol/L), 2.4 is added to the measured serum sodium. A description and link to the Model for End-Stage Liver Disease (MELD) calculator, the formula currently used for liver allocation by the United Network for Organ Sharing, from the VA National Hepatitis C website. Given that hyperglycemia can reduce serum sodium, sodium is adjusted elevated glucose using the following formula:Īdjusted Sodium = Measured Serum Sodium + MELD score has been shown useful both in predicting short-term survival in groups of patients on the waiting list for liver transplantation as well as the risk of postoperative mortality. Sodium values less than 125 mmol/L will be set to 125, and values greater than 137 mmol/L will be set to 137. The revised MELD uses the MELD-Na score, which is as follows: 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 original MELD score is calculated using the following formula: The change is projected to save 50-60 lives per year. The decision to adjust the MELD score was done to increase access to transplants and reduce waiting list mortality rates by better prioritizing those most in need of a liver. The Model for End-Stage Liver Disease (MELD) calculator provides a score (number) based on how urgently someone. The original MELD score included renal function, bilirubin and INR, while the revised MELD also includes serum sodium. It is specifically used to prioritize candidates waiting for liver transplantation.Īs of 2016, MELD-Na score has replaced the historical MELD score for use by the United Network for Organ Sharing (UNOS). Limitations The MELD score is a statistical test. Department of Health & Human Services, has a MELD Calculator that anyone can use. Organ allocation is determined by the Organ Procurement. The Organ Procurement & Transplantation Network, part of the U.S. The MELD score estimates a patients chances of surviving their disease during the next three months. The MELD score (Model for End-Stage Liver Disease) is used to estimate prognosis in patients with liver failure. Since the formula used to determine the score is complex, a MELD calculator is often to do the number crunching.
