  • Hospital-acquired pneumonia leading cause of HAI
    Hospital-acquired pneumonia (HAP) is the 2nd most frequent cause of hospital-acquired infection, numbering around 300,000 cases each year.  
  • Drug-resistant MRSA expensive to treat
    As an example, the median treatment cost for drug-resistant MRSA patients over a 6-month period was 118% higher than the cost of treating drug-susceptible MRSA strains.  
  • 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.  
  • Mortality rate from hospital-acquired pneumonia
    The mortality rate for hospital-acquired pneumonia ranges from 38% to more than 70%.  
  • Risk of HAIs from hospitalization increases with age
    Hospitalized elderly patients are 2 – 5 times more likely to develop a healthcare-associated infection than younger patients.
