Objective To evaluate the role of Extended Scope (ES) audiologists in managing adult Ear Nose and Throat (ENT)/Otology waitlists and analyse patient re-presentation rate to the ENT service within 12 months of being discharged from the clinic. Design A retrospective cohort study assessing the efficacy of ES audiologists, measuring the discharge rate from ENT waitlists, the rate of escalation to ENT care, and the rate and reasons for any re-presentations to care. Study sample 394 adult patients. Results Of the referred patients, 95% (n = 374) were deemed suitable for ES care. Of these, 75% were discharged without further ENT intervention, 20% required escalation to ENT, and 5% were returned to the waitlist. Only one patient re-presented for care within 12 months. The inclusion of patients with CHL/MHL and vestibular symptoms marked an expansion from our previous work. The re-presentation rate was notably lower compared to other allied health ES clinics. Conclusion The ES Audiology clinic demonstrates a high discharge rate with a low incidence of patient re-presentation, highlighting the ES audiologists’ efficiency in managing non-urgent ENT cases. The study supports the continued use and expansion of ES roles to ensuring timely and quality care for patients on ENT waitlists.
