When is an antibiotic time-out typically performed as part of stewardship?

• A. 24h after first administration
• B. 48-72h after first administration
• C. 2 weeks after first administration
• D. Only upon patient request

Answer: (B)

Antibiotic time-out is a deliberate checkpoint in stewardship that happens after initial empiric therapy has begun, to reassess the plan based on new information. The best timing is about 48 to 72 hours after the first dose. This window allows culture results and susceptibilities to return and gives you a sense of how the patient is responding clinically. With that data, you can narrow the spectrum (de-escalate), switch from IV to oral if feasible, adjust dosing, or discontinue therapy if infection is unlikely. Skipping this reassessment or doing it much later undermines the goal of optimizing therapy and avoiding unnecessary broad-spectrum use. Early review at 24 hours is often not sufficient to obtain meaningful microbiology data, and waiting two weeks misses the opportunity to tailor therapy promptly. The time-out is not something done only at patient request; it is a standard stewardship step applied to most patients started on antibiotics.
