Why is de-escalation of antibiotics important in hospital practice?

• A. To reduce antimicrobial resistance and adverse events
• B. To shorten monitoring tasks
• C. To increase antibiotic exposure
• D. To complicate treatment

Answer: (A)

De-escalation means starting with broad-spectrum antibiotics when the infection is not yet characterized and then narrowing the therapy to the most appropriate, targeted agent once culture results and the patient's response are known. This approach helps reduce antimicrobial resistance and adverse events because patients are exposed to fewer broad-spectrum drugs, which lowers selective pressure for resistant organisms and decreases toxicity risks. It also can lessen costs and the risk of complications like C. difficile infection. The other options don’t fit because de-escalation does not aim to shorten monitoring tasks, increase antibiotic exposure, or complicate treatment; it seeks safer, more appropriate, and more efficient therapy.
