Blood culture: hematogenous staph aureus pneumonia stats

- nearly always positive blood culture
- positive in only about 25% of cases in which inhalation or aspiration is responsible for the CAP

32

How often can specific microbiologic cause be established

50%

33

How antibiotic treatment is chosen

- pathogen is identified
- empiric treatment

34

Factors that effect antibiotic chosen for treatment

- comorbidities, immunosuppression
- risk factors for multidrug resistant pathogens (MDR): hospital workers
- resistance patterns
- environmental exposures

35

Importance of timing of treatment

- interval of more than 4 hours b/w initial presentation and first antibiotic dose is associated with increased in hospital mortality

36

Treatment for patients stable enough to be treated as outpatients

- treated empirically
- cause of infection not sought b/c of substantial cost of testing
- choose antibiotic which covers most common organisms

37

Treatment for patients being admitted to the hospital

- guidelines recommend empirical therapy with broader spectrum antibiotics
- test for microbial diagnosis

38

What if influenza is active in the community

- antiviral treatment is recommended as soon as possible for all patients with suspected or confirmed infection

39

Pneumonia prevention

- pneumococcal vaccination
- influenza vaccination
- smoking cessation

40

Pneumococcal vaccine

1. pneumovax
2. prevnar

41

Pneumovax

- 23 valent polysachharide
- covers 88% of strains causing bacteremia/meningitis
- indicated for elderly or patients with chronic health conditions

42

Prevnar

- 13 different strains
- indicated for elderly

43

Influenza vaccination

- 20,000 deaths annually
- prevention is most effective management strategy
- everyone 6 months of age and older should get vaccine every season

44

Importance of pneumococcal vaccine

- key to prevent INVASIVE pneumococcal disease

45

What is the most common infectious cause of death in the world
