A Guide to Pediatric Antibiotic Allergy Testing: A Report from the United States Drug Allergy Registry.

Pediatric antibiotic labels are common, and unnecessary antibiotic avoidance is associated with negative personal and public health outcomes; as a result, there is an increasing emphasis on the importance of pediatric antibiotic allergy evaluations. Different testing strategies have been advised, including skin testing and challenge testing with varied doses and duration. Established consensus testing protocols are lacking.

Derivation and Validation of an Electronic Health Record Penicillin Allergy De-Labeling Prevalence Measure.

With no standard method to capture penicillin allergy de-labeling prevalence across populations, we developed and validated a simple penicillin allergy de-labeling prevalence measure from electronic health records that achieved perfect sensitivity (100.0%), high specificity (99.4%), and strong agreement with a comprehensive algorithm that included free-text manual review (Kappa=0.

AAAAI Position Statement on Changing Electronic Health Record Allergy Documentation to "Alerts" to Lead to Easily Understood, Actionable Labels.

The term "allergy" is inaccurate for the vast majority of the contents in the current allergy fields of electronic health records (EHRs). While EHRs have transformed access to health information and streamlined the delivery of care, their ability to reliably indicate medications, vaccines, or foods that mandate avoidance versus preferences or mild intolerances, is suboptimal. The current systems are reactive instead of being proactive and frequently fail to communicate the appropriate course of action.

Bibliometric analysis of the trends and evolution in β-lactam allergy research.

Background: β-Lactams remain the most reported drug allergy globally, with the volume and diversity of related drug allergy research continuing to accumulate. Recognizing evolving research trends can help inform future directions and encourage synergistic collaborations.

Objective: We conducted a comprehensive bibliometric analysis of all publications relevant to β-lactam allergy, with a focus on longitudinal publication rates, international collaborations, and key word/trend analysis.

Improving Clinical Practice Through Patient Registries in Allergy and Immunology.

Patient registries are a mechanism for collecting data on allergic and immunologic diseases that provide important information on epidemiology and outcomes that can ultimately improve patient care. Key criteria for establishing effective registries include the use of a clearly defined purpose, identifying the target population and ensuring consistent data collection. Registries in allergic diseases include those for diseases such as inborn errors of immunity (IEI), food allergy, asthma and anaphylaxis, pharmacological interventions in vulnerable populations, and adverse effects of pharmacologic interventions including hypersensitivity reactions to drugs and vaccines.

Evaluation of patients labeled with a penicillin allergy to promote antimicrobial stewardship in dental practice.

Background: Approximately 10% of the US population self-reports a penicillin allergy history or are labeled as penicillin allergic. However, from 90% through 99% of these patients are not allergic on formal evaluation.

Case Description: Patients labeled as penicillin allergic receive broader-spectrum and sometimes less-effective antibiotics, thereby contributing to increased treatment failures, antibiotic resistance, and adverse drug reactions.

Predicting Penicillin Allergy: A United States Multicenter Retrospective Study.

Background: Using the reaction history in logistic regression and machine learning (ML) models to predict penicillin allergy has been reported based on non-US data.

Objective: We developed ML positive penicillin allergy testing prediction models from multisite US data.

Methods: Retrospective data from 4 US-based hospitals were grouped into 4 datasets: enriched training (1:3 case-control matched cohort), enriched testing, nonenriched internal testing, and nonenriched external testing.

Examining cefazolin utilization and perioperative anaphylaxis in patients with and without a penicillin allergy label: A cross-sectional study.

Study Objective: To compare the occurrence of cefazolin perioperative anaphylaxis (POA) in patients with and without a penicillin allergy label (PAL) to determine whether the prevalence of cefazolin POA differs based on the presence of a PAL.

Design: Cross-sectional study.

Setting: A large U.
