  • Community Acquired Pneumonia (CAP) – suggestive symptoms

    Any ≥ 2 of the following are suggestive for CAP:

    • fever / hypothermia
    • rigors
    • sweats
    • new / increased cough (± sputum)
    • chest discomfort
    • new onset dyspnoea
    • confusion (especially elderly)

    CAP – Investigations:

    • FBC, EUC, Glc
    • ± CXR – generally patients with normal CXR will not benefit from intravenous antibiotics
      • advanced age
      • renal / cardiac / CLD / CNS disease / malignancy / immunosuppression
      • RR > 30 / SBP < 90 / DBP ≤ 60 / acute confusion
      • Os2 saturation < 90%
      • bilateral / multilobar involvement on CXR

    CAP – Management (basic questions to ask):

    1. Is it pneumonia?
    2. How severe is the pneumonia?
    3. Is hospitalisation appropriate?
    4. What therapy should be commenced?
    5. Are there any special considerations?

    CAP – pathogens:

    • Strep. pneumonia
    • Chlamydia pneumoniae
    • Chlamydia psittaci
    • Mycoplasma pneumoniae
    • Haemophilus influenzae
    • Moraxella catarrhalis
    • respiratory viruses
    • less common, but important:
      • Legionella spp.
      • S. aureus
      • Gram negative bacilli
      • tropical pathogens (northern Australia)
        • Acinetobacter baumannii
        • Burkholderia pseudomalle
