1

what should be investigated for pneumonia etiology?

local epidemiology
travel
specific exposures (birds, caves)
admissions / antibiotics

2

what are the most common microorganism causes of pneumonia?

strep pneumo
viruses (influenza)
mycoplasma pneumo
legionella

3

what organisms should be considered in pneumonia cases post-influenza after previous abx or lung disease?

staph aureus
enterobacteriaceae
pseudomonas

4

anaerobic organisms are typically seen in what situations?

aspiration (alcohol, seizure, stroke)

5

what do anaerobic organisms cause in the context of pneumonia?

lung abscess and empyema

6

what is required for pneumonia diagnosis?

clinical findings
CXR

7

what are the physical findings in the lungs for pneumonia?

tachypnea (over 24)
crackles and consolidation (33%)

8

what are the blood findings for pneumonia?

leukocytosis with left shift

9

what is the gold standard for pneumonia diagnosis?

CXR infiltrate

10

why is establishing specific pathogen for CAP not always required?

empiric therapy is generally very successful

11

in what situations is identification of the organism considered critical for pneumonia?

legionella
influena A/B and MERS
community acquired MRSA
agents of bioterrorism

12

how are the majority of pneumonia cases treated, generally?

empirically

when is sputum gram stain and culture recommended for CAP?

ICU admission
failure of abx
cavitary changes on imaging
immunocompromised host
alcoholism

14

when are sputum samples useful?

must be an acceptable sample

pleural effusion
epidemic pneumonia
evidence of drug resistance

17

what agents are used for non-ICU inpatient therapy?

respiratory quinolone or
