Description
Summary:Objectives To determine patient-reported symptoms and clinical factors associated with mimics and differences in health-seeking behaviour versus stroke.Design This is a post-hoc analysis of a cross-sectional survey of interviews on patient-reported factors in patients admitted with suspected stroke. Patients were categorised as genuine stroke or mimic. The surveys were conducted from February 2018 to January 2019.Setting Two non-comprehensive stroke centres in Denmark.Participants Patients≥18 years (no upper age limit) admitted with symptoms of stroke to one of the non-comprehensive stroke centres or transferred from a comprehensive- or primary stroke centre were eligible for inclusion. 592 patients were included.Outcome measures Symptoms or clinical factors associated with stroke mimics. Logistic regression analysis was performed to identify factors associated with mimics. Secondarily, the number of strokes versus mimics presenting at a healthcare facility within 3 hours contacted the emergency medical service (EMS) and arrived by ambulance.Results Of 592 suspected patients with stroke, 113 (19.1%) were mimics; most frequently peripheral vertigo (24.7%) and migraine (11.5%). Factors associated with a higher likelihood of mimics were female sex (OR 1.79, 95% CI 1.14 to 2.79), high Scandinavian Stroke Scale scores (OR 1.05, 95% CI 1.02 to 1.09, per point increase), and vertigo (OR 1.86, 95% CI 1.18 to 2.95). Factors associated with a lower likelihood of mimics were increasing age (OR 0.96, 95% CI 0.95 to 0.98 per year increase), reported limb weakness (OR 0.52, 95% CI 0.30 to 0.89) and difficulty steering (OR 0.51, 95% CI 0.28 to 0.93).There was no difference between groups in the proportion of patients for whom time from symptom onset to healthcare services contact exceeded 3 hours (52.2% vs 53.7%, p=0.78). Fewer mimics contacted the EMS first, were accepted at a primary stroke centre and arrived by ambulance (p<0.05 for all variables).Conclusion Patient-reported vertigo and migraine are common stroke mimics. Increasing age and unilateral limb symptoms increase the likelihood of a stroke. Although symptoms are similar, prehospital pathways differ between mimics and genuine patients with stroke.
