The number of hospital stays involving pressure ulcers increased by nearly 80% between 1993 and 2006, from 281 300 to 503 300, according to an analysis by the Agency for Healthcare Research and Quality.
The analysis, based on data from the 2006 Nationwide Inpatient Sample, a nationally representative database of US hospital stays, raises questions about the quality of patient care (http://www.hcup-us.ahrq.gov/reports/statbriefs/sb64.pdf). In more than 90% of the cases, patients were admitted for the treatment of another disorder and a pressure ulcer was a secondary condition, suggesting it may have developed during the hospital stay.
