The federal government tallies the number of nurse and aide staffing hours each day for residents at each of the nation's roughly 15,000 nursing homes. It ranks each facility on a five-star scale, with five as the highest, after taking into account how frail the home’s patients and residents are. This chart also displays the percentage of the home’s staff who leave within a year. The national turnover average is 54%; lower turnover rates are considered superior.
