Treatment of Osteomyelitis with Sepsis in Children: Presumed AHO in Ill-Appearing or Rapidly Progressive Presentations
Children with presumed acute hematogenous osteomyelitis (AHO) who appear severely ill, present with sepsis, or have a rapidly progressive bone infection represent a high-acuity subgroup requiring immediate, structured intervention. This protocol addresses that specific clinical scenario.
Clinical Situation
Sepsis
This protocol applies when a child with presumed AHO is ill-appearing, presents with sepsis, or has a rapidly progressive bone infection. In these cases, waiting for invasive diagnostic results before initiating treatment is not appropriate — the clinical urgency requires immediate action.
Approach — Partial Overview
Management centres on immediate empiric intravenous antimicrobial therapy alongside early surgical debridement of the infected bone and any associated abscesses. Agent selection, sequencing, and step-down criteria are detailed in the full protocol.
The complete regimen — including which agents apply to which severity levels, and when and how to transition — is available below.
Treatment Goals
- Rapid resolution of bacteremia — serial blood cultures becoming negative within 1–2 days of initiating therapy
- Resolution of fever within 3–5 days

- In children with presumed AHO who are ill-appearing or have a rapidly progressive infection, we recommend starting empiric antimicrobial therapy immediately rather than withholding antibiotics until invasive diagnostic procedures are performed (strong recommendation and moderate certainty of evidence).
- Vancomycin is a common initial choice for children who are critically ill at presentation, regardless of regional MRSA prevalence.
- In children with AHO who present with sepsis or have a rapidly progressive infection, we recommend debridement of the infected bone and any associated abscesses as soon as possible after diagnosis, rather than treating with medical therapy alone (strong recommendation and moderate certainty of evidence).
- Rapid resolution of bacteremia (serial blood cultures become negative when obtained within 1–2 days after the initiation of therapy and source control).
- Fever, when present, usually resolves within 3 to 5 days in uncomplicated courses.
