Rapid molecular testing is associated with decreased broad-spectrum antibiotic use among patients with streptococcal bloodstream infections

We investigated the impact of rapid diagnostic testing with real-time stewardship intervention on patients with Streptococcal bacteremia. Compared to pre-intervention, patients in the post-intervention group received more rapid antibiotic de-escalation (42 vs 88 h), and were more commonly de-escalated to narrow-spectrum (86% vs 52%) and oral antibiotics (30% vs 14%).
