Methods Study Design: Retrospective chart review Patient Population: Pediatric patients admitted to the 5 th floor of UAMC Diamond Children’s Medical Center between January 22, 2013 and April 4, 2013. Inclusion Criteria: o Positive chest x-ray for pneumonia o Inpatient order for antibiotic therapy o Age > 3 months and < 18 years Exclusion Criteria: o Aspiration pneumonia o History of antibiotics for the treatment of pneumonia within the previous month o Cystic fibrosis o Viral pneumonia Procedures: Data Collection: o Electronic medical records of patients admitted to the 5 th floor of UAMC Diamond Children’s Medical Center were evaluated. o For patients who met the inclusion criteria, the following information was collected: sex, allergies, weight, age, antibiotic prescribed (date and dose), history of lung disease, chest x-ray results, and history of readmission due to pneumonia. o Pre-intervention data collection was conducted January 22, 2013 to February 14, 2013. o Post-intervention data collection was conducted March 7, 2013 to April 4, 2013. Intervention: o A brief presentation on the pre-intervention results and the IDSA pediatric CAP guidelines (accounting for local resistance patterns and hospital formulary) was given to pediatric medical residents at teaching day on March 6, 2013. o Pediatric residents were provided with a laminated reference card containing guideline recommendations on antibiotic selection and dosing to attach to their lanyards [Figure 1]. Statistical Methods: Chi-square test, a priori alpha < 0.05 Figure 1. Pediatric Pneumonia Guidelines Reference Card Intervention Background and Introduction Objectives Background: o In 2011, the Infectious Diseases Society of America (IDSA) released clinical practice guidelines for the treatment of Community-Acquired Pneumonia (CAP) in pediatric patients. 1 These guidelines recommend ampicillin as the preferred parenteral therapy and amoxicillin as the preferred oral therapy for the treatment of non-complicated pneumonia due to Streptococcus pneumoniae. o Adherence to evidence-based guidelines has been shown to decrease morbidity and mortality. 2 o This project focuses on the prescribing portion of the medication use process at The University of Arizona Medical Center (UAMC)-Diamond Children’s. UAMC is a teaching hospital in Tucson, Arizona and Diamond Children’s Medical Center treats pediatric patients with a variety of conditions. Supportive Research: o Newman et al. found that implementation of clinical practice guidelines and an antimicrobial stewardship program in a children’s hospital led to a significant increase in use of ampicillin for the treatment of uncomplicated CAP and speculated that this has the potential to minimize the development of resistant strains of bacteria. 3 o Smith et al. analyzed the importance of education and the use of guidelines for CAP in a pediatric setting and found significant changes in the prescription patterns after the creation of an antimicrobial stewardship task force and the release of the guidelines. 4 o McCabe et al. examined the use of CAP guidelines in adults and discovered that the implementation resulted in a decrease in length of stay, duration of parenteral treatment, and in-hospital deaths. 5 o Dean et al. discovered an association between 30 day mortality, length of hospital stay, and readmission rate in CAP inpatient treatments when guidelines were appropriately used. 2 Goal: o It is important to investigate prescribing patterns and assess adherence to guideline recommendations because this could improve patient outcomes and decrease antibiotic resistance. o Examine prescribing patterns for the treatment of CAP in pediatric patients in comparison to the IDSA treatment guidelines. o Assess the effect of a brief educational intervention on prescribing practices. o The pneumonia season time frame limited the total number of collected cases. o The lack of patient outcomes measurements in comparison to antibiotic prescribed. o The inability to measure the effects of antibiotic resistance in relation to guideline adherence. o The ability to distinguish between antibiotics prescribed in the emergency department versus the pediatric floor based on electronic medical records.

Results!o  Over a time period of 72 days, the medical records of 45 pediatric pneumonia

patients between the ages of 5 months and 15 years were analyzed [Table 1].!o  Forty-four antibiotic treatments were recorded during the pre-intervention

period and 37 were recorded during the post-intervention period [Table 2].!o  There was a statistically significant difference between pre- and post-

intervention ampicillin prescribing (P=0.015) [Table 2].!

o  Adherence to the IDSA pediatric CAP guidelines for parenteral therapy improved.!•  After the intervention, there was a statistically significant 5-fold increase

in ampicillin prescribing. !•  Additionally, there was a 3-fold decrease in ceftriaxone prescribing.!

o  Adherence to the IDSA CAP guidelines for amoxicillin was appropriate prior to the intervention and remained similar during the post-intervention period. !
