Podcast 679: Antibiotics for CAP

Contributor:  Peter Bakes, MD

Educational Pearls:

  • Community-acquired pneumonia (CAP) is normally stratified into outpatient-candidates vs. inpatient candidates for treatment
  • For outpatient treatment, antibiotic selection is driven by presence or absence of comorbid health conditions (chronic lung/kidney/liver disease, DM, immunocompromised state, alcoholism, asplenia)
    • No comorbidities: High dose amoxicillin, doxycycline, azithromycin
    • Comorbidities: augmentin, cephalosporin, doxycycline, macrolide with fluoroquinolones as an alternatives
  • For inpatient treatment, standard treatment is a macrolide and 3rd-generation cephalosporin
    • Prior MRSA isolate or pseudomonas isolate as well as severe pneumonia are indications for adding MDR organism coverage with vancomycin and anti-pseudomonal coverage
