Improved Diagnosis and Treatment of Bone and Joint Infections Using an Evidence-based Treatment Guideline

Our institution created a multidisciplinary guideline for treatment of acute hematogenous osteomyelitis (AHO) and septic arthritis (SA) in response to updates in evidence-based literature in the field and existing provider variability in treatment. This guideline aims to improve the care of these patients by standardizing diagnosis and treatment and incorporating up to date evidence-based research into practice. The primary objective of this study is to compare cases before versus after the implementation of the guideline to determine concrete effects the guideline has had in the care of patients with AHO and SA.This is an Institutional Review Board-approved retrospective study of pediatric patients age 6 months to 18 years hospitalized between January 2009 and July 2016 with a diagnosis of AHO or SA qualifying for the guideline. Cohorts were categorized: preguideline and postguideline. Exclusion criteria consisted of: symptoms >14 days, multifocal involvement, hemodynamic instability, sepsis, or history of immune deficiency or chronic systemic disease. Cohorts were compared for outcomes that described clinical course.Data were included for 117 cases that qualified for the guideline: 54 preguideline and 63 postguideline. Following the successful implementation of the guideline, we found significant decrease in the length of intravenous antibiotic treatment (P<0.001), decrease in peripherally inserted central catheter use (P<0.001), and an increase in bacterial identification (P=0.040). Bacterial identification allowed for targeted antibiotic therapy. There was no change in length of hospital stay or readmission rate after the implementation of the guideline.Utilizing an evidence-based treatment guideline for pediatric acute hematogenous bone and joint infections can lead to improved bacterial diagnosis and decreased burden of treatment through early oral antibiotic use.Level III- retrospective comparative study.
