The incidence of adult disabled patients staying with their pediatricians long after their 18th birthday is one of many issues raised in a report released by The Arc of Massachusetts, an advocacy group for people with intellectual and developmental disabilities. The study, "Left Out in the Cold: Health Care Experiences of Adults with Intellectual and Developmental Disabilities in Massachusetts," found that many disabled adults face longer waits than most people finding good internists, and that prevents them from getting the best care for common adult conditions.
