What are the three goals for optimizing antibiotic use to reduce resistance?

• A. Spectrum; Dose; Duration
• B. Dose; Selection; Duration
• C. Selection; Dose; Duration
• D. Prescribing; Dose; Monitoring

Answer: (C)

The key idea is that reducing resistance comes from three practical actions at the patient level: choosing the right antibiotic, giving the right amount, and using it for the right length of time. Selecting the right agent means picking a drug with an appropriate spectrum for the likely pathogens and local resistance patterns, with plans to narrow or de-escalate as soon as culture results are known. Dosing properly ensures the exposure is enough to effectively kill the bacteria (aligned with PK/PD principles) while accounting for patient factors like kidney function or body weight. Using antibiotics for the shortest effective duration limits unnecessary exposure, which reduces selective pressure that drives resistance. The option that combines selection, dose, and duration captures these essential, actionable goals.
