Northwestern University’s Sanjay Mehrotra has developed an innovative model that could help ease kidney distribution inequities among regions in the U.S. and ultimately help save hundreds of lives. His mathematical model, which takes into account a number of different factors, simulates and optimizes donor kidney distribution.Mehrotra will discuss his research in a presentation titled “Addressing Allocation Inefficiencies and Geographic Disparities” at the American Association for the Advancement of Science (AAAS) annual meeting in Chicago. His presentation is part of a symposium titled “Transplant Organ Shortage: Informing National Policies Using Management Sciences” to be held from 10 to 11:30 a.m. CST Friday, Feb. 14, in Columbus IJ of the Hyatt Regency Chicago.Mehrotra also will participate in a press briefing to be held at 1 p.m. CST the same day in Vevey Room 3 of the Swisstel Chicago.In addition to Mehrotra, two other Northwestern professors will discuss issues related to organ shortage during both the symposium and press briefing.Michael Abecassis, M.D., chief of the division of organ transplantation and founding director of the Comprehensive Transplant Center at Northwestern University Feinberg School of Medicine, will offer a brief overview of the current issues facing organ allocation.John Friedewald, M.D., associate professor in medicine and surgery at Feinberg and director of clinical research at Northwestern University Feinberg School of Medicine Comprehensive Transplant Center and transplant nephrologist at Northwestern Memorial Hospital, will speak about policy changes in kidney allocation that were developed during his recent term as chair of the United Network for Organ Sharing Kidney Transplantation Committee.Nearly 100,000 people in the United States are waiting for kidney transplants, but only 17,000 kidneys are available annually from both living and deceased donors. There are major regional inequalities in access to organs because of supply and demand disparities among different areas of the country. A person in one state might get a kidney within a year, while someone in another state might wait up to four years. As a consequence, nearly 5,000 people die each year waiting for a kidney transplant.Logistically, organ allocation is a difficult problem. …
