Whitesburg ARH Hospital, which got a C, shows detail for infection issues and tabs for other issues. More Kentucky hospitals than the last time got a grade of A on a nonprofit group's rating of patient safety in hospitals, but for the fifth grading period in a row, most of the 45 Kentucky hospitals got Cs.   The Leapfrog Group, based in Washington, D.C., rates more than 2,600 hospitals. Most of Kentucky's 126 hospitals were not rated, but those that are have a majority of the hospital beds in the state.  The group does not grade small hospitals with "critical access" status because they don't have to report quality measures to the federal government, nor does it grade specialty hospitals, government hospitals, or hospitals for which there aren't enough publicly reported data.Â
