Objectives
• Discuss the impact of the timing of initiation of antimicrobials in patients with nosocomial pneumonia
• Discuss the impact of appropriate initial selection of antimicrobials for treatment of nosocomial pneumonia

Nosocomial Pneumonia
Health Care Associated (HCAP)
Hospital Acquired (HAP)
Ventilator Associated (VAP)
• Hospitalized for ≥ 2 d during past 90 days• Nursing Home or Long Term Care facility• Recent IV antibiotics, chemotherapy, or wound care in past 30 days• Dialysis
• > 48 hr after hospitalization
• > 48 – 72 hr after ET intubation

Identifying Pneumonia
√ Fever√ Leukocytosis√ Purulent tracheal secretions√ New or persistent infiltrates√ Oxygenation

Impact of Delays in Initiation of Antimicrobial Therapy for Septic Shock
• Retrospective review conducted in 14 ICUs and 10 hospitals in the U.S and Canada
• 2,371 adult patients with septic shock• 80% survival in patients receiving appropriate antimicrobial
within first hour of documented hypotension– Each hour of delay decreased survival by 8%– Mortality already significantly higher by second hour compared to
appropriate therapy within first hour (OR 1.67; 95% CI 1.12-2.48)• Time to initiation of appropriate antimicrobial therapy was
single strongest predictor of survival– Median time = 6 hours

Effects of Inappropriate Initial Antimicrobial Therapy of Severe Sepsis
• 904 patients with severe sepsis or early septic shock
• Inappropriate antimicrobials in 211 (23%)
• Factors associated with inappropriate therapy:– Nosocomial infection– Infection with MDR pathogens– Fungal or polymicrobial infection
• Inappropriate therapy associated with increased mortality (OR 1.8, 95% CI 1.2-2.6)
39%

Common Pathogens in Nosocomial Pneumonia
• Methacillin-resistant Staphylococcus aureus• Pseudomonas aeruginosa • Enteric gram- negative rods– Klebsiella sp.– Enterobacter sp.– Serratia sp.
• Acinetobacter sp.• Stenotrophomonas maltophilia

Guideline Recommendations• Begin IV antibiotics as early as possible and always within the first hour of
recognizing severe sepsis and septic shock
• Broad spectrum antimicrobial active against likely bacterial/fungal pathogens and with good penetration into lungs
• Consider combination therapy in Pseudomonas infections
• Combination therapy ≤ 3-5 days and de-escalation following susceptibilities
• Reassess antimicrobials daily to optimize efficacy, prevent resistance, avoid toxicity, and minimize costs
• Duration of therapy typically limited to 7-10 daysDellinger RP. Crit Care Med 2008; 36:296-327Am J Respir Crit Care Med 2006;171:388-416
