Background/Aims: Differential diagnosis of acute vertigo syndrome is challenging. In the acute medical setting, it is difficult to ascertain whether a person has definite peripheral vestibular pathology or a posterior circulation stroke. Mismanagement of these groups within our service is costly, with regards to correct medical input, MRI scan use and bed use within acute stroke services and the hospital setting. Research has demonstrated that the Head Impulse, Nystagmus, and Test of Skew (HINTS) test is efficacious, specific and sensitive in non-UK countries in determining if acute vertigo patients have dangerous (stroke) or benign (peripheral vestibular) pathology. It is not widely used in the UK. This may be due to well-known themes in implementation evidence such as cultural and clinician factors, as well as the lengthy time it takes to embed research into clinical settings. Methods: We have started exploring, using Plan Do Study Act cycles, if the HINTS test can be successfully used in a large acute stroke service and the quality improvement effects this may have for patients (correct diagnosis, education/management and follow-up), financially to the Trust (efficient use of MRI scanning) and to the Stroke Pathway (effective bed use/acute medical management). Results: Early results in round one of the quality improvement plan show that HINTS is a feasible bedside test to complete with 100% accuracy in the patients it was used on within the acute stroke pathway. This involved one stroke consultant and the patients' diagnosis with HINTS was assessed against routine follow-up MRI as appropriate. HINTS training has now been provided to all the stroke consultant and registrar team, A&E registrars and A&E advanced clinical practitioners, to senior physiotherapists in the acute stroke pathway and to the stroke alert nurses. Data gathering has commenced for round two, focusing further on bed use effects, as well as consideration of staff satisfaction with HINTS, and development of a recommended pathway for acute vertigo syndrome patients.
