Nearly 3,000 skilled nursing facilities have been recognized as a top provider in U.S. News & World latest ratings of the best nursing homes. 

The organization unveiled its 2019-20 ratings Tuesday. California had the highest number of nursing homes on the list, with 169 facilities that received a high-performing rating in short-term rehabilitation and 157 designated as high performing in long-term care. 

Researchers evaluated more than 15,000 nursing homes. The scores also used a new long-term care rating from each nursing home to generate its overall scores. 

The ratings previously relied heavily on domain star rating data from the Centers for Medicare & Medicaid Services’ Nursing Home Compare website, according to Zach Adams, senior health data analyst at U.S. News & World Report. The organization added its short-stay rehabilitation rating last year.

Metrics that the new methodology take into account include success in preventing ER visits, pneumonia vaccination rates and staffing levels, specifically concerning federal standards for registered nurses. 

About 1,140 nursing homes were designated as high-performing facilities out of 13,685 nursing homes that received a Long-Term Care Rating, according to a release.

“We wanted to see how consistently homes were meeting (federal minimum) standards (for RNs),” Adams told McKnight’s. “It’s not just how your home does overall and how much staff they have but also how they’re faring on some of their light staff days. Overall, I think nursing homes performed pretty well.”
