Why It Matters
The use of antibiotics is standard treatment for bacterial infections, but 30%–50% of antibiotic prescriptions in hospital settings are unnecessary or inappropriate. This increases the risk of antibiotic-resistant infections. Reducing improper use of antibiotics can decrease antibiotic resistance and improve patient outcomes.
