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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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 OF EVIDENCE: Level III- retrospective comparative study.

Decreasing Exposure to Radiation, Surgical Risk, and Costs for Pediatric Complicated Pneumonia: A Guideline Evaluation.

OBJECTIVES: This report describes the creation and successful implementation of a complicated pneumonia care algorithm at our institution. Outcomes are measured for specific goals of the algorithm: to decrease radiation exposure, surgical risk, and patient charges without adversely affecting clinical outcomes. METHODS: We describe steps involved in algorithm creation and implementation at our institution. To depict outcomes of the algorithm, we completed a retrospective cohort study of hospitalized pediatric patients with a diagnosis of complicated pneumonia at a single institution between January 2010 and April 2016 who met criteria for the algorithm. Charts were manually reviewed and data were analyzed via Wilcoxon rank sum, χ2, and Fisher's exact tests. RESULTS: Throughout the algorithm creation process, our institution began to see a change in practice. We saw a statistically significant decrease in the number of patients who underwent a chest computed tomography scan and an increase in patients who underwent a chest ultrasound (P < .001). We also saw an increase in the use of chest tube placement with fibrinolytics and a decrease in the use of video-assisted thoracoscopic surgery as the initial chest procedure (P ≤ .001) after algorithm implementation. These interventions reduced related charges without significantly affecting length of stay, readmission rate, or other variables studied. CONCLUSIONS: The collaborative creation and introduction of an algorithm for the management of complicated pneumonia at our institution, combined with an effort among physicians to incorporate evidence-based clinical care into practice, led to reduced radiation exposure, surgical risk, and cost to patient.

Management of Rabies Prophylaxis for Potential Bat Exposures in a Level III Neonatal Intensive Care Unit.

This report describes the unique challenges of managing potential exposure to bats in a neonatal intensive care unit. The outcome demonstrates that rabies post-exposure prophylaxis can be safely administered to preterm infants with evidence that preterm infants are able to develop adequate titers post vaccination.

Hospitalizations Due to Respiratory Syncytial Virus Outside of the Typical Season.

Objective: Respiratory Syncytial Virus (RSV) is the most common cause of bronchiolitis and viral lower respiratory tract infections in children. It is associated with annual winter epidemics across the United States, typically October through April. Our objective is to describe the clinical characteristics of children hospitalized outside the typical RSV season and to compare them with those admitted during the season. Methods: A retrospective chart review was conducted of all patients who were hospitalized at Children's Hospital of Austin from May 2000 to September 2006 and had a positive RSV antigen test. Descriptive statistics, tests of differences, and associations between patients diagnosed in the off-season versus typical season were conducted. Results: A total of 850 charts of RSV-positive cases were reviewed. Of these, 45 patients (5.3%) were admitted during the off-season. The following variables were statistically significantly associated with diagnosis in the off-season versus typical season: mean birth weight (2704 g vs. 3204 g respectively, p=0.0001); gestational age at birth less than 36 weeks (OR=4.35; 95% CI: 2.2, 8.6); history of neonatal intensive care unit (NICU) admission at birth (OR=6.04; 95% CI: 2.9, 12.5); and multiple birth (OR=3.38; 95% CI: 1.2, 9.2). Conclusions: Infants with RSV infection outside of the typical season were more likely to have been premature, of lower birth weight, the products of multiple births, and admitted to the NICU at birth.
