Boston Children's Hospital and Children's Hospital of Philadelphia tie for first place in U.S. News & World Report's 2012-13 Best Children's Hospitals Rankings. Much of the quality related data collected for the rankings are based on measures underpinned by health information technology, such as electronic health records. U.S. News & World Report released the rankings on June 5. They feature 50 hospitals in each of 10 pediatric specialties: cancer, cardiology and heart surgery, diabetes and endocrinology, gastroenterology, neonatology, nephrology, neurology and neurosurgery, orthopedics, pulmonology and urology. The rankings will also be published in the U.S. News Best Hospitals 2013 guidebook, which will be available in August.
