You are being granted access to the information contained on this site in order to enable you to compare hospitals by viewing the results of the Leapfrog Hospital Safety Score (the “Safety Score”) initiative. The Safety Score grades hospitals on their overall performance in keeping patients safe from preventable harm and medical errors by using grade of A, B, C, D or F. The grades are derived from expert analysis of publicly available data using evidence-based, national measures of hospital safety, including data reported through CMS Hospital Compare, the Agency for Healthcare Research and Quality, the Centers for Disease Control and Prevention, The Leapfrog Hospital Survey and secondary data sources. The measures include process, structural and outcomes measures. The measures have been put into two domains – process/structural and outcomes – with each domain receiving an equal weight of 50% to make up the overall Hospital Safety Score. Nearly 2700 hospitals will be receiving a grade but certain hospitals will not, including critical access hospitals, specialty hospitals, pediatric hospitals, hospitals in Maryland and territories exempt from public reporting to CMS and other hospitals where adequate data is not available. Unless otherwise agreed upon in writing between you and Leapfrog, you may use the grades only for your personal or internal, noncommercial use and must not reproduce, republish, distribute, modify, reverse engineer or otherwise exploit the Hospital Safety Score or this website in whole or in part, in any manner not expressly permitted by this Agreement.
