Polyethylene glycol hypersensitivity, patient outcomes in a 7-year retrospective study.

Background: Immediate IgE-mediated hypersensitivity reactions to polyethylene glycol (PEG) are rare. Our understanding of PEG hypersensitivity is limited.

Objective: To evaluate the clinical characteristics and investigation outcomes of the largest cohort of patients with PEG allergy reported.

How Do Hospital-Specific Data Dictionaries Impact Competency Level With Data Collection: A National Survey.

Background: Trauma registry staff are tasked with high-quality data collection to support program requirements. Hospital-specific data dictionaries are increasingly used to ensure accurate data collection, yet it is unknown how such a resource impacts a trauma registry team's competency with data collection.

Objective: This study sought to explore whether having a hospital-specific data dictionary affected trauma service team members' self-reported competency level with abstracting required and nonrequired data elements.

Amoxicillin hypersensitivity: Patient outcomes in a seven-year retrospective study.

Background: The beta-lactam antibiotic amoxicillin and the beta-lactamase inhibitor clavulanic acid in combination with amoxicillin are known to cause both immediate- and nonimmediate-type hypersensitivity.

Objective: To characterize a large cohort of patients with a history of amoxicillin or amoxicillin-clavulanic acid hypersensitivity.

Methods: A retrospective analysis was conducted of the demographics, presentation, investigation, and management of 331 patients presenting to 1 allergy center with a history of hypersensitivity to amoxicillin or amoxicillin-clavulanic acid.

Trauma Registry Data Collection Practices and the Impact of Hospital Data Dictionaries: A National Survey.

Background: Trauma programs are required to collect a uniform set of trauma variables and submit data to regional, state, and or national registries. Programs may also collect unique data elements to support hospital-specific initiatives.

Objective: This study explored what additional data elements are being collected by U.

Piperacillin-Tazobactam Hypersensitivity: A Large, Multicenter Analysis.

Background: Piperacillin/tazobactam is a broad-spectrum penicillin. Hypersensitivity reactions are less commonly reported than with other penicillins except in patients with cystic fibrosis.

Objective: Detailed clinical characterization of a patient cohort referred with suspected piperacillin-tazobactam hypersensitivity.
