ITE-1 and ITE-2 stacks - 2 Flashcards
With what meds may I treat patients admitted to ICU with pneumonia?
Respiratory fluoroquinolone + anti-pneumo beta-lactam OR aztreonam
OR
Antipseudomonal + quinolone + vanc
With what meds may I treat patients admitted with pneumonia?
Respiratory quinolone
OR
Beta-lactam + newer macrolide
Which meds offer anti-pseudomonal coverage?
- Zosyn
- meropenem
One way to preventdrug resistance is torefrain from giving an antibiotic agent that…
the patient has received within the past 3 months
How often are blood cultures postive in CAP eval? What infectious agent is isolated in 2/3 of all positive cases?
- 5%-14% positive blood cultures
- Strep pneumo in 2/3 of positive cases
Which meds are macrolides?
-mycins:
Azithro-
Clarithro-
Erythro-
Which meds are considered respiratory quinolones?
-floxacins
Gemi-
Levo-
Moxi-
Which meds are considered Beta-lactams?
Amoxicillin Augmentin Cefotaxime Ceftriaxone Ampicillin/Sulbactam (Unasyn)
Which meds are anti-pneumococcal/anti-pseudomonal beta lactams?
Zosyn
Meropenem
Cefipime
Imipenem
With which meds may I treat my ICU patient with pseudomonal pneumonia?
Anti-pneumococcal/Anti-pseudomonal Beta lactam (IV)
+
Fluoroquinolone (IV)
OR
Aminoglycoside + Antipneumococcal Fluoroquinolone
What is BIRP criteria used for?
to identify patients @ increased risk of drug-resistant HCAP
B: broad-spectrum abx in past 3 months
I: ICU admission
R: Resident of NH or poor functional status
P: Priior hospitalization w/in past 3 months
With what meds may I treat my NH patient with pneumonia?
In consideration of increased risk of drug-resistant bacteria…
- Anti-pseudomonal +
- Antipseudomonal fluoroquinolone OR Aminoglycoside
- CONSIDER: Anti-MRSA (Vanc, Linezolid)
Which drugs are Aminoglycosides
Gentamycin
Tobramycin
How long should I treat my patient with CAP?
- minimum of 5 days
- until afebrile 48-72 hours
- until no more than 1 CAP-associated sign of clinical instability
What are the more common pathogens that cause HCAP?
- MRSA
- S. pneumonia
- P. aeruginosa
- MSSA
- H. influenza
In what patient populations might I consider including coverage for MRSA when treating for pneumonia?
- one or more BIRP + factors
- if severe CAP (admission to ICU)
- after an episode of the flu
To which patients should I offer PPSV-23?
- > 65 yo - single dose
- children at risk > 2yo (8 wks after PCV 13)
- 2-64 yo if chronic disease or resident of any institution
PPSV-23 and PCV 13: What is the relevant timing for administration?
If PCV 13 given –> wait 8 weeks –> give PPSV-23
If PPSV-23 given –> wait 1 year –> PCV-13
What are the generalized rules for reading TB skin tests?
Rules are based on risk of exposure to TB:
- if NO RISK: 15 mm (prior BCG ok)
- IF MINIMAL RISK: 10mm (chronic dz, immigrant, housing facility)
- If INCREASED RISK: 5 mm (exposure, immunocompromised, etc)
What is the booster phenomenon as it relates to Tuberculin skin testing (TBT)?
TST initially negative —> wait 1-3 weeks –> repeat test is +
- This phenomenon indicates history of TB in the past - NOT an active infection
All pneumonia treatment begins with usage of which antibiotic? What risk factors RE: microbial involvement direct decisions for other treatments to add?
Start with quinolones: Then broaden coverage based on risk factors for: - pseudomonas - pneumococcus - MRSA - antibiotic resistance
