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. Together, these alterations will not only level the playing field for women, but improve accuracy for all patients, Kim said.| Mayo Clinic Transplant Staff | | Comments (13) Using three years of data from candidates who were on the liver transplant waitlist from 2016 through 2018, the researchers fine-tuned the model, adding 1.3 points for female candidates, including albumin (a measure of liver function and malnutrition) as a fifth blood test value, limiting the maximum level of creatinine, and adjusting for interactions among the variables. Last year, Kim, Kwong and their colleagues published a proposal for MELD 3.0 to address these issues. Patients on the waitlist today are more likely to be older, have alcoholic liver disease or fatty liver disease, and have comorbidities like diabetes and obesity - differences that make their mortality less predictable by the original model. When the model was created, nearly a third of patients on the waitlist had hepatitis C. In addition, the demographics of liver disease patients have changed since 2002, reducing the overall accuracy of MELD scoring, according to Allison Kwong, MD, an instructor in gastroenterology and hepatology as well as a co-author of the MELD 3.0 paper. One study found that women on the waitlist were 14.4% less likely than men to receive a liver transplant and 8.6% more likely to die waiting for one. “One point is all you need to make a difference at the margin,” Kim said.

Women typically have less muscle mass than men, so, on average, they tend to score 1- to 2-points lower than men, even if they have the same level of kidney dysfunction. Muscle mass affects the body’s level of creatinine. “Women have been disadvantaged in this system, and that was a completely unintended consequence of this score.” “People have shown that the transplant rate for women is lower and waiting list mortality is higher,” Kim said. In recent years, data has revealed a new concern with MELD scoring: sex disparity.

We were able to allocate organs to people who need it most,” Kim said.Ī 2016 update to the score, which was also based on work by Kim, added sodium to the formula and is known as MELDNa. “It really shuffled the waiting list, reduced the risk of waitlist mortality and increased transplants.
