Emergency room visits for adults 19 to 25 dropped slightly after implementation of the Affordable Care Act (ACA). But visits for mental illnesses and circulatory diseases increased significantly, according to a study published online this month in the Annals of Emergency Medicine. Study author Renee Hsia, MD, of the University of California San Francisco said, “Increased health insurance coverage reduced ER visits by young people for conditions that can be treated in office-based settings, but the lack of mental health resources continues to bring these patients to the ER in ever larger numbers. We also saw an increase in patients with diseases of the circulatory system, such as non-specific chest pain. There was a big decrease in ER visits for complications of pregnancy among young people, which is important as it was among the top reasons they visited the emergency room prior to the implementation of the ACA.”
