Health care-associated pneumonia

  • Health care-associated pneumonia (HCAP) is a distinct entity
  • HCAP includes any patient with pneumonia and 1 or more of the following:
    • hospitalization for 2 or more days in an acute care facility within the preceeding 90 days
    • nursing home patients
    • patients of long-term care facilities
    • patients who attend a hospital or hemodialysis clinic
    • patients who received IV antibiotics, chemotherapy, or wound care within 30 days of infection
  • Data indicate that the mortality for HCAP is higher than CAP
  • The most common organisms in HCAP include S.aureus, P.aeruginosa, Klebsiella species, Haemophilus species, and Escherichia species
  • An initial recommended antibiotic regimen includes a combination of an antipseudomonal cephalosporin plus a fluoroquinolone plus an agent active against MRSA
