Abstract Number: Esoc2026a1150 a Single-Centre Retrospective Audit of Final Clinical Diagnoses in Patients Trigerred as Fast Positive in a Dublin Teaching Hospital

Abstract Background and aims The FAST assessment is used to enable the rapid identification of patients with suspected stroke. Reviewing the final diagnosis of FAST activations allows assessment of diagnostic accuracy 1%). A large proportion of patients (32%) had other diagnoses reflecting a variety of alternative diagnoses beyond those classically associated with FAST symptoms. Conclusions The FAST assessment identified a high proportion of patients with a final diagnosis of acute stroke/TIA. Nevertheless a majority of patients presenting as FAST positive were stroke mimics related to other neurological, systemic conditions & other miscellaneous causes. Findings highlight that while the FAST assessment is effective for rapid recognition, a significant proportion of FAST positive patients will be stroke mimics which has implications for resource utilisation.
