De-escalation in Severe Abdominal Sepsis: Association With Cure, Not Proof of Benefit
This single-center retrospective propensity-matched cohort links antibiotic de-escalation after source control to better cure and lower mortality in severe intra-abdominal infection, but design limits make it a stewardship-supportive signal rather than proof of benefit for ICU pharmacists.

De-escalation boosts survival in severe intra-abdominal infections.
Antibiotic de-escalation can enhance antimicrobial stewardship and improve outcomes in severe intra-abdominal infections (IAIs). De-escalation increased clinical cure rates (79.8% vs. 63.5%) and reduced mortality (9.6% vs. 21.2%) in matched cohorts. The study's findings support integrating de-escalation into antimicrobial stewardship, considering its impact on clinical outcomes and mortality. Retrospective nature is a limitation. De-escalating antibiotics post-source control improves outcomes in severe intra-abdominal infections.
