These results are entered into a mathematical formula using the UNOS MELD score calculator. Your MELD score is calculated using four blood test results - bilirubin, serum sodium, INR and serum creatinine. Your care team will notify you of any major changes to your list status. You may have several changes to your score during your time on the wait list. When your updated blood work is delivered to your doctor, the transplant team will calculate your MELD score using an online calculator and submit the changes to UNOS directly. The results of your blood work are used to calculate your score for the waiting list. Since your health condition can change frequently, your doctor will send you to the lab for updated blood work routinely, so they can assess your condition often. The MELD score helps hospitals maintain fair lists across the nation so the livers that become available can go to those patients with the most urgent need. The MELD score was put into place so the sickest patients get the first livers available. The same MELD score definition and calculation are used by all transplant centers in the U.S.Īs of today, there are over 14,000 people waiting for a liver transplant, and there are not enough deceased donor livers to meet that need. The MELD score can range from 6 (less ill) to 40 (gravely ill). It’s used by hospitals and the government to prioritize allocation of deceased donor livers for transplant. MELD is an acronym for model for end-stage liver disease, and MELD score is the score provided to patients based on how urgently they need a liver transplant in the next three months. We’ve put together this blog post to help answer the most frequently asked questions about the MELD score. Having a strong understanding of your MELD score and how it’s calculated is important because it often influences how long you’ll wait for your liver transplant. If you’re a liver transplant patient, you’ve likely heard your doctors talk about your MELD score. Therefore, in principle, the score should only be applied after these reversible conditions have been treated, according to the authors ( Kamath 2007).| Mayo Clinic Transplant Staff | | Comments (13) One of the exclusion criteria for the original data set was absence of acute reversible conditions such as spontaneous bacterial peritonitis or prerenal azotemia secondary to dehydration.Several conditions are “standard MELD exceptions” and receive a different score (see Next Steps > Critical Actions): hepatocellular carcinoma, hepatopulmonary syndrome, portopulmonary hypertension, familial amyloid polyneuropathy, primary hyperoxaluria, cystic fibrosis, hilar cholangiocarcinoma and hepatic artery thrombosis.Scores range from 6 to 40, with higher scores correlating with increased severity of liver dysfunction and higher three-month mortality.The MELD Score predicts three-month survival in patients (age 12+) with liver cirrhosis.MELD can be used on any patient with end stage liver disease irrespective of cirrhosis etiology.Values should be no more than 48 hours old.
