U.S. News and World Report released its 2013 rankings of the best adult and children’s hospitals in the United States, along with an Honor Roll of the overall top 18 hospitals in the nation. The rankings cover nearly 5,000 medical centers across the country and span 16 medical specialties. Hospitals ranking near the top of at least six specialties earn a spot on the Honor Roll.

Many of the hospitals on the list are household names–from Johns Hopkins in Baltimore to the Mayo Clinic in Minnesota, while some like UPMC-University of Pittsburgh Medical Center or Barnes-Jewish Hospital/Washington University in St. Louis are a little less known throughout the country.
