The Auditory Brainstem Response - Are South African ENT's Missing the Point?

Abstract

The use and misuse of the auditory brainstem response (ABR) test by hearing professionals is often related to the extent and nature of the training they have received. This study used a postal survey based questionnaire to investigate the levels of training in, knowledge about, and appropriateness of referral for, ABR testing in Ear, Nose and Throat (ENT) surgeons and registrars in Gauteng, South Africa. Thirty-seven actively practising ENT specialists and registrars were sampled using a convenience sampling technique. Overall, a poor level of training and knowledge in ABR and its related areas of audiology was identified. This was mirrored by a high demand for further education. Considering the prevalence of auditory disorders in South Africa, and the push towards primary care and early intervention, this study's results highlight the need for improved training in ABR for ENT surgeons and registrars.
