Key Takeaway

Consider short-course IV or oral antibiotics for uncomplicated pediatric BJIs, but weigh low certainty.

This meta-analysis evaluated whether short-course intravenous antibiotic therapy (≤5 days) or oral-only treatment is as effective as longer intravenous regimens for uncomplicated bone and joint infections (BJIs) in previously healthy children older than 3 months. The analysis included 813 children across 6 studies, with 3 studies contributing to the meta-analysis.

The primary outcome was treatment success. The pooled effect size was 1.65 (95% confidence interval: 0.46-5.98), indicating no statistically significant difference between short-course or oral-only therapy and longer intravenous regimens. However, the confidence interval is wide, reflecting imprecision.

The authors note limitations including imprecision and the limited number of estimable studies. The certainty of evidence for treatment success is low, meaning the true effect may be substantially different from the estimate.

For clinical practice, short-course intravenous therapy or oral-only treatment may be as effective as longer intravenous regimens for uncomplicated pediatric BJIs in healthy children. However, given the low certainty, clinicians should apply these results cautiously and consider individual patient factors.

How this fits prior evidence

This meta-analysis extends prior coverage on antibiotic strategies by addressing a common pediatric infection. While prior items focused on inhaled antibiotics for cystic fibrosis and bronchiectasis, bowel preparation with oral antibiotics for rectal surgery, and antibiotic stewardship in adults, this review synthesizes evidence for shortening IV duration in pediatric BJIs. It confirms the trend toward shorter antibiotic courses but with low certainty, contrasting with the stronger evidence for combined bowel preparation. It fills a gap by focusing on healthy children with uncomplicated infections, a population not covered in prior items.

Researchers looked at how to treat bone and joint infections (BJIs) in healthy children over three months old. They compared shorter intravenous (IV) antibiotic treatments, lasting five days or less, and oral-only treatments against longer IV treatment plans. The study included 813 children across several different studies.

The results showed no significant difference in treatment success between the shorter treatments and the longer IV regimens. This suggests that for children with uncomplicated infections, a shorter course of medicine might be just as effective as a longer hospital stay.

However, the evidence for this finding is not very strong. The researchers noted that the data was imprecise and came from a limited number of studies. Because of these limitations, doctors should be cautious when using these results to change standard care. Patients should talk to their doctors about the best treatment plan for their specific situation.

What this means for you:

Short-course IV or oral antibiotics may be as effective as long IV treatments for certain childhood bone infections.

Common questions

Is a shorter course of antibiotics safe for children with bone infections?

The study found no significant difference in treatment success between short-course intravenous antibiotics (5 days or less) and longer intravenous regimens for children with uncomplicated bone and joint infections. However, the evidence is not very certain due to the small number of studies and imprecise data. You should talk to a doctor to determine the safest plan for a child.

Can oral antibiotics replace long IV treatments for bone infections?

For healthy children over 3 months old with uncomplicated infections, oral-only treatments showed no significant difference in success compared to longer IV treatments. Because the evidence is limited and imprecise, this finding should be used cautiously by medical professionals when deciding on a treatment plan.

Who is eligible for these shorter treatment options?

The study specifically looked at healthy children over 3 months old who had uncomplicated bone and joint infections. While the results showed no difference in success between short and long treatments, the low certainty of the evidence means it may not apply to all types of infections.

BACKGROUND: Pediatric bone and joint infections (BJIs) are traditionally treated with prolonged intravenous antibiotics, although the optimal duration remains uncertain. Recent studies support shorter intravenous courses and, in some cases, oral therapy alone. However, the minimum effective intravenous duration remains undefined. OBJECTIVES: To evaluate the effectiveness of abbreviated intravenous regimens in previously healthy children with acute BJIs. METHODS: MEDLINE, CENTRAL and Scopus were searched up to December 31, 2024, for studies including children >3 months old with uncomplicated BJIs treated with ≤5 days of intravenous antibiotics. Studies with comorbidities, prosthetic joints or surgical-site infections were excluded. Risk of bias was assessed using RoB-2 and ROBINS-I, and certainty of evidence with GRADE. This systematic review was registered in PROSPERO (CRD42024614740). RESULTS: Of 6 studies (813 children) included in the qualitative synthesis, 3 were eligible for meta-analysis. The pooled odds ratio for treatment success with short-course intravenous therapy (≤5 days) or oral-only treatment compared with longer intravenous regimens was 1.65 (95% confidence interval: 0.46-5.98), showing no significant difference between groups. Statistical heterogeneity was low ( I2 = 0%). Sensitivity analyses confirmed the direction and stability of findings. The certainty of evidence for treatment success was rated low due to imprecision and limited estimable studies. CONCLUSIONS: This systematic review and meta-analysis suggest that short-course intravenous therapy-or even exclusive oral antibiotic treatment-may be as effective as longer intravenous regimens for uncomplicated pediatric BJIs in healthy children. However, given the low certainty of evidence, these strategies should be applied cautiously and guided by clinical judgment. Further high-quality trials are needed to confirm these findings.
