What is antimicrobial stewardship, and what is de-escalation in this context?

• A. Coordinated strategies to optimize antibiotic use; switching to narrower-spectrum antibiotics when possible
• B. Routine prescribing of broad-spectrum antibiotics for all infections
• C. Stopping antibiotics as soon as symptoms improve
• D. Using antibiotics only for viral infections

Answer: (A)

Antimicrobial stewardship is about guiding antibiotic use so patients get the best possible treatment while minimizing harm, resistance, and costs. A central tactic within this approach is de-escalation: starting with a broad, empiric antibiotic when the infection could be caused by several organisms, then narrowing to a narrower-spectrum antibiotic once culture results and the patient’s response indicate a specific pathogen and susceptibility. This keeps broad coverage available for when it’s truly needed, but avoids unnecessary exposure to powerful drugs as more information becomes available.

In practice, this means using the right drug, at the right dose, for the right duration, and adjusting the choice as data come in. The described option captures this idea: coordinated strategies to optimize antibiotic use, including switching to narrower-spectrum agents when possible. Other options reflect common missteps or misunderstandings, such as routinely giving broad-spectrum antibiotics for all infections, stopping antibiotics just because symptoms improve without ensuring the full course is completed, or using antibiotics for viral infections at all.
