Weighing options: empiric antibiotic use and stewardship opportunities in critically ill patients with community-acquired pneumonia

TL;DR

This study finds that critically ill patients with pneumonia often get broad antibiotics without clear need, but MRSA treatment is adjusted faster with better testing.

Contribution

The study highlights empiric antibiotic use patterns and de-escalation opportunities in ICU patients with community-acquired pneumonia.

Findings

Critically ill patients often received empiric anti-MRSA and antipseudomonal antibiotics without clear risk factors.

De-escalation of anti-MRSA therapy occurred more quickly, possibly due to MRSA PCR assays.

Abstract

In this retrospective study, critically ill patients with community-acquired pneumonia frequently received empiric anti-methicillin-resistant Staphylococcus aureus (MRSA) and antipseudomonal antibiotics despite having few or no guidelines-endorsed risk factors. De-escalation of anti-MRSA therapy was quicker, likely aided by MRSA polymerase chain reaction assays.
