Abstract

Aim: Early diagnosis of osteoarticular infections (OAI) in children and effective treatment prevents complications. The objective of this study was to evaluate effectiveness and safety of shortened intravenous antibiotic treatment of OAI. Incidence, diagnostics and pathogens of paediatric OAI were assessed.

Methods: This retrospective study included all paediatric OAI admissions to The Children's Hospital Iceland in 2006-2020. The treatment was evaluated by dividing the study cohort into two groups. The simplified treatment group received intravenous antibiotics for less than 7 days. The longer intravenous group received intravenous antibiotics for a minimum of 7 days.

Results: In total, 205 cases of OAI were included: 106 osteomyelitis, 83 septic arthritis and 16 with both. Age standardised incidence was 17 per 100,000 children and decreased over the study period (p = 0.004). A pathogen was identified in 37% (75/205) of cases of which 65% (49/75) were Staphylococcus aureus and 12% (9/75) Kingella kingae. Simplified treatment was not associated with increased risk of complications.

Conclusion: This study supports claims that simplified treatment for OAI is safe and effective. Further simplification of treatment might be viable. For uncertain reasons the incidence of OAI was decreasing in Iceland, predominantly in young children.

Keywords: Staphylococcus aureus; Kingella kingae; antibiotic treatment; bone infections; joint infections.
