  • Comorbidities and hospitalization higher with HAIs
    Patients with HAIs have more comorbidities (2.8 vs. 1.9) and in-hospital mortality (9% vs. 1.5%), compared to all other hospitalized patients.  
  • Close to 1/2 of HAIs in patients 65+
    Around 45% of all hospital-acquired HAIs in 2007 were in patients age 65 and older.  
  • Hospital stays longer when HAIs involved
    The average length of hospital stays are 19 days longer with healthcare-associated infections than without (24.4 days versus 5.2 days).  
  • Late Mortality and Sepsis
    Compared with patients not in the hospital, sepsis in hospitalized patients was associated with a 22.1%  increase in late mortality during a 2 year follow-up period.  
  • Antibiotic resistance of Klebsiella pneumoniae on the rise
    Resistance of Klebsiella pneumoniae to antibiotics has dramatically increased- from 5.3% to 11.6% for third generation cephalosporins (between 1999 and 2010), and from <0.1% to 4.5% for carbapenams (between 2002…
