The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

© 2021 Cambridge University Press. All rights reserved. Introduction: Otitis externa (OE) accounts for 1.1-1.3% of patient presentations in primary care and 25% of urgent referrals to ENT. We aimed to explore: 1) OE clinical decision-making at the primary-secondary care interface; 2) OE prevalence; and 3) Recent trends in antimicrobial resistance in OE-related bacterial isolates and ototopical prescribing. Methods: This is a mixed-methods study drawing on data from primary and secondary care and open NHS sources. Results: 101 GP survey respondents reported frequently prescribing oral antibiotics for OE. GP consultations for OE increased 25% over 15 years. GP ototopical preparations cost the NHS £7,410,440 in 2006; £11,325,241 in 2016. 162 consecutive hospital OE-related bacterial isolates yielded 128 Pseudomonas spp., 18 resistant to gentamicin, 7 to ciprofloxacin. 10 guidelines reviewed showed systematic inconsistencies. Conclusion: GPs reported regularly prescribing oral antibiotics for OE. Antimicrobial drug resistance is common in OE. Available guidance is suboptimal.
