Arizona, California, Illinois and Ohio scored the best marks for hospital care in a new report that says quality varies “significantly” from state to state in key health areas linked to mortality rates. During 2005-2011, hospitals in those states outperformed others when treating patients for four key conditions or procedures studied: coronary artery bypass graft, heart attack, pneumonia and sepsis, according to the report to be released today by Healthgrades, a for-profit provider of information about physicians and hospitals. Those four areas combined to make up 54 percent of all hospital-related deaths in the U.S. according to a recent report in the Desert Sun.
