Researchers from Columbia University School of Nursing and RAND Corporation analyzed infections in nursing homes over a five-year period from 2006-2010, using Minimum Data Set assessment data – the information submitted by the facilities to the Centers for Medicare and Medicaid. They found significantly increased infection rates for pneumonia, urinary tract infections (UTIs), viral hepatitis, septicemia, wound infections, and multiple drug-resistant organisms (MDROs), conditions that raise the risk of complications and death. Only tuberculosis rates did not show an increase.
Approximately 1.6 million to 3.8 million infections occur among U.S. nursing home residents each year. The new study found that UTIs remain, by far, the most frequently reported type of infection, but they also showed the smallest rise in prevalence – just 1 percent. Pneumonia was the second most common infection, and its prevalence rose 11 percent from 2006 to 2010. Infection rates increased 69.7 percent for viral hepatitis, 25.2 percent for septicemia, 24.1 percent for pneumonia, 15.7 percent for MDRO and 4.6 percent for wound infections.
