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.

Grades range from A to D. The Leapfrog Group explains that its rating system is focused entirely on errors, accidents, injuries and infections.

Hospital safety grades are released by the nonprofit group twice a year, in the spring and in the fall.

The group relies on a panel of experts to select the measures used in the methodology and to develop a scoring system.
