Objectives: Osteoarticular infections (OAIs) in children pose significant risks if incorrectly managed. We introduced a clinical practice guideline (CPG) to decrease use of broad-spectrum and intravenous (IV) antibiotics for OAI treatment. The primary aims of our project were to decrease the percent of patients with empirical broad cephalosporin use to 10% and decrease IV antibiotic therapy on discharge to 20% while increasing narrow-spectrum oral antibiotic use to 80% within 24 months.
Methods: We used quality improvement methodology to study patients diagnosed with OAIs. Interventions included multidisciplinary workgroup planning, CPG implementation, education, information technology, and stakeholder feedback. Outcome measures were the percentage of patients prescribed empirical broad-spectrum cephalosporins, percent discharged on IV antibiotics, and percent discharged on narrow-spectrum oral antibiotics. Process measures included percent of patients hospitalized on medicine service and infectious diseases consultation. Balancing measures included rates of adverse drug reactions, disease complications, length of stay, and readmission within 90 days. The impact of the interventions was assessed with run and control charts.
Results: A total of 330 patients were included over 96 months. The percentage of patients with empirical broad cephalosporin coverage decreased from 47% to 10%, percent discharged on IV antibiotics decreased from 75% to 11%, and percent discharged on narrow-spectrum oral antibiotics increased from 24% to 84%. Adverse drug reactions decreased from 31% to 10%. Rates of complications, readmissions, and length of stay were unchanged.
Conclusions: Through development and implementation of a CPG for OAI management, we demonstrated decreased use of empirical broad-spectrum antibiotics and improved definitive antibiotic management.
