This study looks at how kids with mild pneumonia are treated with antibiotics. Pneumonia is an infection in the lungs. The study is comparing two ways to give antibiotics: **Safety Net Antibiotic Prescribing (SNAP)** and **immediate antibiotic prescribing**. In SNAP, parents are told to wait and only give antibiotics if their child doesn't get better after 72 hours. The immediate approach involves giving antibiotics right after the doctor's visit. The goal is to see which method helps kids get better while reducing unnecessary antibiotic use. **Key Points:** - Participation lasts **14 days** with surveys on days 4, 7, and 14. - Children will be part of either the SNAP group or immediate antibiotic group randomly. - The study involves **no compensation**, but aims to ensure safer treatment for children. The study happens at 19 locations across the U.S., including emergency departments and clinics. It involves about 2,000 kids aged 12 months to less than 6 years. Parents will fill out surveys to help researchers understand how well the treatments work and if parents are satisfied.
