State laws to combat disability-based discrimination in the organ transplant process aren't working, according to new research from The Ohio State University College of Medicine. The study, published in JAMA Internal Medicine, examines national policies designed to help all patients have a fair chance to receive an organ transplant. Despite 40 states passing laws prohibiting disability-based discrimination in the organ transplant process, people with intellectual and/or developmental disabilities (IDD) are still less likely to receive a kidney transplant than those without IDD.
