Five days or less for non-severe childhood pneumonia: similar failure rates, far fewer missed doses

Design

Systematic review and meta-analysis of 10 randomised trials

Population

8,970 immunocompetent children with non-severe community-acquired pneumonia

Primary outcome

Treatment failure, relapse and non-adherence

Effect

Failure RR 1.07 (95% CI 0.93-1.24); non-adherence RR 0.35 (0.24-0.50)

A systematic review and meta-analysis pooled ten randomised trials (8,970 immunocompetent children under 18) with non-severe community-acquired pneumonia, comparing antibiotic courses of five days or less with longer courses.

Treatment failure did not differ (RR 1.07, 95% CI 0.93 to 1.24), nor did relapse (RR 1.04, 0.72 to 1.49), and both results were consistent across trials. Non-adherence fell by about two-thirds with the shorter course (RR 0.35, 0.24 to 0.50). Adverse events were similar but varied widely between trials.

Shorter courses already have trial support; what this adds is adherence. In practice a ten-day course is often abandoned at day four or five anyway, so prescribing five days matches what children actually take, with less antibiotic exposure. It applies to non-severe pneumonia in otherwise well children, not to complicated or severe disease.

• Consider a five-day course for non-severe community-acquired pneumonia in otherwise healthy children.
• Exclude severe pneumonia, effusion, immunocompromise and young infants before shortening.
• Give parents a clear end date and a reason to return if fever persists beyond 48 to 72 hours.
• Non-adherence with short courses was about a third of that with longer ones.

Why it matters

The longer course mostly buys missed doses, not better outcomes.

Don't overread it

The analysis was not designed to formally prove non-inferiority, and it excludes severe or complicated pneumonia.

The statistics, in plain English

A risk ratio of 1.07 with an interval from 0.93 to 1.24 means short courses could be up to about a quarter worse or slightly better; the data cannot rule out a small disadvantage. The adherence benefit is much firmer, with an interval well below 1.
