Pediatric Provider Utilization of a Clinical Decision Support Alert and Association with HIV Pre-exposure Prophylaxis Prescription Rates

Objectives An electronic clinical decision support (CDS) alert can provide real-time provider support to offer pre-exposure prophylaxis (PrEP) to youth at risk for human immunodeficiency virus (HIV). The purpose of this study was to evaluate provider utilization of a PrEP CDS alert in a large academic-community pediatric network and assess the association of the alert with PrEP prescribing rates. Methods HIV test orders were altered for patients 13 years and older to include a hard-stop prompt asking if the patient would benefit from PrEP. If providers answered “Yes” or “Not Sure,” the CDS alert launched with options to open a standardized order set, refer to an internal PrEP specialist, and/or receive an education module. We analyzed provider utilization using a frequency analysis. The rate of new PrEP prescriptions for 1 year after CDS alert implementation was compared with the year prior using Fisher's exact test. Results Of the 56 providers exposed to the CDS alert, 70% (n = 39) responded “Not sure” to the alert prompt asking if their patient would benefit from PrEP, and 54% (n = 30) chose at least one clinical support tool. The PrEP prescribing rate increased from 2.3 prescriptions per 10,000 patients to 6.6 prescriptions per 10,000 patients in the year post-intervention (p = 0.02). Conclusion Our findings suggest a knowledge gap among pediatric providers in identifying patients who would benefit from PrEP. A hard-stop prompt within an HIV test order that offers CDS and provider education might be an effective tool to increase PrEP prescribing among pediatric providers.

1127. Validation of an Adult and Pediatric Beta-Lactam Allergy Risk Stratification Tool

Background Penicillin allergies are commonly reported, yet more than 95% of these patients can tolerate β-lactams. A comprehensive allergy history is essential when determining which patients can safely receive a β-lactam but is rarely obtained. When available, interpretation of the history is often limited by lack of comfort in determining risk of an allergic reaction. Our antimicrobial stewardship and allergy team created a standardized allergy history questionnaire and risk stratification tool. The purpose of this study was to validate this tool by comparing risk levels assigned by various clinicians to that assigned by an allergist. Methods We prospectively identified 50 adult and 50 pediatric patients hospitalized between July 1, 2020 and March 31, 2021 with an allergy to penicillin, amoxicillin, ampicillin, or cephalexin. Patients with severe non-IgE mediated reactions were excluded. All patients (or caregivers) were interviewed by the same pharmacist using the allergy questionnaire. Clinicians from various subspecialties, including an adult and pediatric allergist, an adult and pediatric infectious diseases (ID) physician, an adult and pediatric hospitalist, and an adult and pediatric ID pharmacist, received anonymized completed questionnaires and the risk stratification tool, but were blinded to other clinicians’ responses. The primary endpoint was overall concordance in risk stratification between non-allergists and allergists. Results Overall concordance was 66% (33/50) in adult and 90% (45/50) in pediatric patients (Table 1). Concordance between individual clinicians and the allergist are shown in Figure 1. In adults, anaphylaxis, difficulty breathing, and angioedema were associated with less severe stratification by non-allergists than allergists. No clinicians stratified any pediatric patient into a lower risk category than the allergist. Table 1. Clinician Agreement with Allergist Figure 1. Risk Stratification Severity Compared to Allergist Conclusion Use of a β-lactam allergy risk stratification tool led to agreement with allergist assessment in the majority of patients. Variation in risk assignment was greater in adult patients; however, non-allergist pediatric providers assigned all patients at the same or more severe level as the allergist, indicating safety in this population.

1129. Outpatient Prescribing During the COVID-19 Pandemic

Background The Joint Commission requires ambulatory healthcare systems to collect, analyze and report antimicrobial prescribing data. Duke University Health System (DUHS) piloted a dashboard to capture outpatient prescribing for pediatric patients with URI. Implementation in 2020 allowed for an assessment of antibiotic prescribing during the pandemic. Methods We included patients 0 - < 19 years seen at DUHS for URI and pharyngitis from 1/1/2019 -2/21/2021. Patient characteristics included: age, sex, race, ethnicity, Pediatric Medical Complexity Algorithm (PMCA) score and insurance status (public versus private). Provider characteristics included: type (physician, NP, PA) and specialty (pediatrics, family medicine, internal medicine, other). We compared pre- and post-COVID ( March 1, 2020) prescribing and prescribing during telehealth versus in-person visits. A logistic regression model was used to identify factors independently associated with antibiotic prescribing. Results 62,447 children were seen during the study period, 29% of whom received an antibiotic. Amoxicillin was the most commonly prescribed antibiotic (64.4%), followed by cefdinir (11%) amoxicillin-clavulanic acid (10%) and azithromycin (8%). Factors associated with antibiotic prescribing are shown in Table 1. White race, private insurance, visits with nurse practitioners and visits with non-pediatric providers were associated with high prescribing. Higher PMCA scores, indicating greater medical complexity, were associated with decreased likelihood of prescribing. Although the total number of outpatient visits plummeted during the COVID period, rates of prescribing only decreased mildly from 31% to 25% (Figure 1). Table 1. Factors Associated with Antibiotic Prescribing in Logistic Regression Model Conclusion Outpatient prescribing was associated with multiple patient and provider characteristics. Similar to other studies, white race, private insurance, and visits with non-physician, non-pediatric providers were associated with antibiotic prescription. Despite a large decrease in the number of outpatient visits during the pandemic, rates of prescribing for URI decreased minimally. A better understanding of factors associated with antibiotic prescribing during the pandemic may identify priority targets for outpatient stewardship as mitigation strategies are relaxed.
