Assessment of the validity of the beta‐lactam antibiotic allergy assessment tool for use in the rural context, QLD.

Objective(s): The objective of the study was to validate a clinical aid to guide the assessment and management of a patient's listed beta‐lactam antibiotic allergy for use in rural areas of Australia. Design: Rural generalists, pharmacists and junior doctors completed an online assessment of eight patient case studies using the tool. Setting: The study was conducted in the Southern Downs, QLD. Participants: Twenty‐seven rural generalists, nine pharmacists and eight junior doctors. Main outcome measures: The sensitivity of the selected allergy phenotype and management option for each case study was calculated by profession and overall. Hazardous responses were reported by management category and profession. Results: The sensitivity overall for phenotype selection was 82.4% (95% CI, 78.0–86.2) and for management 88.1% (95% CI, 84.2–91.2). The sensitivity for phenotype selection was lower for junior doctors than other professions 73.4% (95% CI, 60.9–83.7), but did not reach statistical significance (p = 0.08). A total of 10/308 responses for management recommended the least restrictive option of direct delabelling or oral challenge, where the correct answer was skin prick testing or referral to an allergist. Conclusion(s): With further education the tool could be a key component of increased antimicrobial stewardship in rural areas in Australia. [ABSTRACT FROM AUTHOR]
