"Errors and infections in hospitals are the third leading cause of death in America, and people deserve to know which of their hospitals are best at preventing them," Leah Binder, president and CEO of Leapfrog, said in a press release.

Medical errors, accidents, injuries and infections are taken into account by Leapfrog when calculating the grades. The goal of the rankings is to determine a patient's risk of further injury or infection if they visit a certain hospital.

Leapfrog assigns A, B, C, D and F letter grades to general acute-care hospitals in the United States. Leapfrog explains that the safety grade includes 27 measures that are taken together to produce a single letter grade representing a hospital's overall performance in keeping patients safe from preventable harm and medical errors.

The group uses performance measures from a variety of sources, including the Centers for Medicare & Medicaid Services, the Leapfrog Hospital Survey and the Centers for Disease Control and Prevention.

Oregon, Virginia, Maine, Massachusetts and Virginia had the highest percentage of hospitals that received an A grade. Four states — Wyoming, Arkansas, Delaware, North Dakota — and the District of Columbia did not have a single hospital that received an A grade.

Overall, Pennsylvania ranked 18th on the list, a slight drop from its Fall 2018 ranking at 14th.
