Background/AimsData are limited on the frequency of ‘consensus’ between sub-specialists attending a neurovascular multidisciplinary meeting (MDM) regarding management of patients with extracranial carotid/vertebral stenoses, and post-MDM ‘adherence’ to advice. This prospective audit/quality improve- ment project collated data at a Neurovascular/Stroke Centre.MethodsData from a weekly MDM were prospectively-recorded to document the proportion of extrac- ranial carotid/vertebral stenosis patients in whom ‘consensus management decisions’ were reached by Neurologists/Vascular Surgeons/Stroke Physicians-Geriatricians. Adherence to MDM advice was analysed in patients with asymptomatic, symptomatic and ‘indeterminate symptomatic status [ISS]’ stenoses, including intervals between symptom onset-MDM discussion +/- intervention.Results115 patients were discussed (September/2017-February/2020). Consensus regarding manage- ment was 96.5% (111/115) overall; 100% (29/29) with asymptomatic carotid stenosis [ACS], 96.5% (55/57) with symptomatic carotid stenosis [SCS], and 93.1% (27/29) with ISS. Overall adherence to MDM advice was 93% (107/115); 100% (29/29) with ACS, 89.5% (51/57) with SCS, 93.1% (27/29) with ISS. Median interval from index TIA/stroke to intervention was 12.5 days (IQR:9-18d), and MDM discussion-to-intervention was 5.5d (IQR:1-7d) in patients with 50-99% SCS.ConclusionsHigh-frequency inter-specialty consensus regarding management/adherence to proposed treatment supports a collaborative, multidisciplinary model-of-care in patients with extracranial arterial stenosis. Service development should shorten intervals between symptoms-MDT discussion-intervention to optimise secondary prevention.
