Accuracy of pressure ulcer events in US nursing home ratings.

All nursing homes certified by the Centers for Medicaid & Medicare Services (CMS) are required to submit select patient safety data which is used to calculate quality ratings. This study compared seven years of self-reported pressure ulcer data with claims-based data for pressure ulcer-related hospital admissions. Similar to earlier research on self-reported falls data, correlations between the self-reported and claims-based data was poor. The authors suggest alternate methods of data collection may provide the public with more accurate patient safety information.
