  • HAIs cost patients additional $43,000 per hospital stay
    Patients with HAIs cost, on average, $43,000 more per hospital stay than those without an infection ($52,096 vs. $9,377).  
  • 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.  
  • Mortality rate from hospital-acquired pneumonia
    The mortality rate for hospital-acquired pneumonia ranges from 38% to more than 70%.  
  • HAI Annual Cost
    Healthcare-associated infections in US hospitals cost $96–$147 billion annually.  
  • Primary sources of HAIs
    Around 2/3 of all HAIs are central-line associated bloodstream infections, catheter-associated urinary tract infections, and ventilator-associated pneumonia. Surgical site infections and Clostridium difficile (C. difficile) are also common HAIs.
