12

how is the severity of CAP assessed?

CURB65
(score of 3 or greater = severe pneumonia)

Where should a patient with CURB65 = 0-1 be treated?

outpatient

14

Where should a patient with CURB65 = 2 be treated?

short inpatient stay

15

Where should a patient with CURB65 = 3 be treated?

admit to hospital

16

Where should a patient with CURB65 = 4-5 be treated?

consider for HDU/ ITU

17

What are some possible complications of pneumonia?

Complications can result from highly virulent organisms or inadequate treatment.
-parapneumonic effusion
-empyema
-lung abscess/ cavitation
-metastatic infection/ abscesses
-ARDS/ multiorgan failure
-death

18

therapy for complications of abscess/ empyema?

drainage
