Research summary
Background and Purpose – Acute vestibular syndrome (AVS) can result in continuous dizziness caused by an inner ear condition or a vertebrobasilar strokes. Misdiagnosis can be common and can lead to poor outcomes. A three-step bedside oculomotor assessment the Head Impulse-Nystagmus-Test of Skew (HINTS) test has been developed to assist differential diagnosis. In the first 48 hours, this is reportedly more sensitive than Magnetic Resonance Imaging (MRI). However, this high sensitivity has only been reported based on evaluation of clinicians with specialist skills or training using HINTS.
Aims – This study aims to employ a cross-sectional online survey to explore current perspectives of clinicians of using the HINTS test within the NHS.
Methodology – An online survey (JISC) will be conducted within North Bristol NHS Trust and University College Hospitals NHS Foundation Trust, targeting clinicians who assess acute dizziness. The survey has been constructed with expert peer review and piloting to explore three main themes: experience, training and perceived confidence of using HINTS.
Results – Quantitative elements of survey responses will be analysed descriptively and using inferential statistics (e.g. chi square) as appropriate. Results of experience, training, and confidence will be compared between groups according to grade of clinician and professional background. Qualitative open response sections of the survey will be analysed thematically and cross-referenced against the quantitative results.
Anticipated data/ conclusions – The survey is anticipated to highlight reasons why clinicians currently use HINTS as well as barriers and limitations that may be in place, which could associate with experience, training or confidence levels. Results are anticipated to inform future research and potential future clinical training packages.
