A new release of data by federal regulators shows nursing home operators are improving.

The percentage of nursing homes that notched deficiency-free surveys rose to 10.2% in 2014, up from 8.8% in 2009, according to the “Nursing Home Data Compendium for 2015.”

Surveys resulting in a finding of substandard care fell 27% over roughly the same span, the Centers for Medicare & Medicaid Services publication said. Pressure ulcer prevalence tumbled from 10% to 5.9%.

Data for the 251-page report was primarily gathered through the CASPER database for survey and certification information, population data from the Bureau of the Census, and the Minimum Data Set.

Providers’ most prevalent deficiencies from 2005 to 2014 were storing and cooking food in a safe and clean way, ensuring the facility is free of accident hazards, providing adequate supervision to prevent accidents, providing necessary care to improve resident well-being and having a program that investigates and controls the spread of infections.
