Antibiotic treatment of pediatric infections in primary healthcare setting: evaluation and comparison of 80 national treatment guidelines with the WHO AWaRe book recommendations.

Background: Antibiotic recommendations for pediatric infections in national standard treatment guidelines (STGs) vary widely, particularly for Access and Watch antibiotics. The WHO AWaRe book recommends Access antibiotics as first-line treatment for over 80% of common infections managed in primary healthcare. This study aims to evaluate the agreement between first and second-line antibiotics in national STGs with AWaRe book recommendations and the inclusion of these antibiotics in Essential Medicine Lists (EMLs). Methods: National STGs of 80 countries were systematically collected from databases and grey literature (up to May 2025). Antibiotic recommendations for the ten most common primary healthcare infections in children were compared with the WHO AWaRe book (2022), the WHO Essential Medicines List for children (EMLc) and national Essential Medicines Lists (nEMLs) where available. Findings: A median of eight STGs per country were collected, with higher numbers in LMICs due to guidelines for cholera and enteric fever. A total of 1124 first-line and 841 second-line antibiotic recommendations were identified. Over 70% of first-line recommended treatments were Access antibiotics, while Watch antibiotics accounted for more than 50% of second-line recommended treatments. First-line recommendations showed strong agreement with WHO guidance, whereas second-line treatments exhibited lower agreement and greater variability across regions. More than 80% of first-line antibiotics were included in the EMLc and nEMLs, although some high-income countries lacked nEMLs. Interpretation: First-line antibiotic recommendations in national pediatric STGs largely align with the WHO AWaRe book guidance focusing on Access antibiotic use. In contrast, second-line treatments vary considerably, commonly recommending Watch antibiotics. Strengthening the evidence base of national STGs and aligning second-line recommendations with the WHO AWaRe book could help meet the 79th UNGA High-Level Meeting on AMR target, which aims for 70% of all human antibiotic use to come from the Access group.
