Empiric antibiotics for HCAP/VAP were appropriate - yet deadly? (Lancet ID) - PulmCCM

In a well-intentioned performance improvement initiative, Daniel Kett and the IMPACT-HAP team prospectively observed 303 patients at risk for MDR pneumonia at four academic hospitals. Surprisingly, more of those who got appropriate antibiotics died (34%) than those treated off-ATS/IDSA guidelines (20%), with Kaplan-Meier-modeled 28-day survival of 65% vs. 79%, p=0.0044. The authors were concerned enough to recommend against continued adherence to ATS/IDSA HCAP antibiotic guidelines, pending a randomized trial. The study was funded by Pfizer, who have been reported to be getting out of the antibiotics business. Lancet Infect Dis 2011;11:181-189. 

 

Donald Craven and Michael Niederman, authors of the ATS/IDSA guideline, didn’t care much for this article. Read what they had to say to us about it.

  1. This is a very important study that deserves careful consideration and further “replication” studies, if possible, or a RCT. What’s interesting is the fact that Pseudomonas was identified way more often in the compliant group than in the non-compliant group: 26% vs 10%. Selection bias? Based mainly on clinical impression?
