Could a 'Wait and See' approach cut antibiotic overuse in kids with pneumonia?
NCT ID NCT06986148
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two ways of giving antibiotics to children with mild pneumonia: giving them right away versus waiting 72 hours to see if symptoms improve. The goal is to see if the 'watch and wait' approach can safely reduce unnecessary antibiotic use. About 2,000 children will take part, and their recovery and antibiotic use will be tracked for 14 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- antibiotics (amoxicillin or similar)
- What this could lead to
- If successful, this could show that a delayed antibiotic strategy is safe and effective for mild childhood pneumonia, reducing unnecessary antibiotic use and resistance.
- What could go wrong
- This is a behavioral strategy trial, not a new drug. The results depend on parents following instructions, and some children may still need immediate antibiotics. It is not a cure or major breakthrough.

Inclusion Criteria: * Aims 1 and 2: * Presenting with signs and symptoms of lower respiratory tract infection * Diagnosed with community-acquired pneumonia (CAP) by a clinician * The treating clinician intends to prescribe antibiotics for CAP, AND * Well enough, as determined by the clinician at the time of the study enrollment visit, to be managed as an outpatient. * Aim 3: * Parent/guardian of child enrolled in the trial, OR * Clinician who makes prescribing decision at the study site, OR * Other practice-based parties (e.g. nurses, pharmacists, medical assistants, practice leaders) at study sites who can comment on the implementation of each prescribing strategy. Exclusion Criteria: * Aims 1 and 2: * Hospitalization within the previous 7 days * Oxygen saturation below 90%, if measured * Incomplete immunization status (e.g., lacking at least 3 doses of the pneumococcal vaccines, typically given as part of the 2-, 4-, and 6-month vaccinations) * Chronic medical conditions that increase the risk of bacterial CAP (e.g., chronic lung disease, cystic fibrosis, sickle cell disease), * Substantially immunocompromised status (e.g., immunodeficiency, active cancer treatment, organ transplant with concurrent immunosuppressive agents) * Receipt of oral or parenteral antibiotics within the previous 7 days * Diagnosis of complicated pneumonia (e.g., empyema, lung abscess) * Known bacterial source of infection warranting immediate antibiotics * Pneumonia diagnosis within the previous 6 months, OR * Prior enrollment in the trial * Inability of the parent or guardian to speak English or Spanish * Aim 3: * Inability of the parent or guardian to speak English
