In Italy the vast majority of TIA and minor strokes are seen in the A&E. Early diagnosis and management of TIA and minor stroke in this setting is habitually difficult and often lead to cost-ineffective hospital admissions. We set up an ultra-rapid TIA service run by neurovascular physicians based on early specialist assessment and ultrasound vascular imaging.

We compared the rate of TIA and minor stroke admissions/discharges in the year before (T0) and in the year during which the TIA service was operating (T1). At T1 57 patients had specialist evaluation and 51 (89.5 %) of them were discharged home. Two (3.5 %) patients had recurrent symptoms after discharge. Seven had a pathological carotid Doppler ultrasound. Four of them had hospital admission and subsequent carotid endoarterectomy within a week. Taking the whole neurology department into consideration at T1 there was a 30–41 % reduction in discharges of patients with TIA or minor stroke. Taking the stroke unit section into consideration at T1 there was a 25 % reduction in admissions of patients with NIHSS score <4 and 40 % reduction in admissions of patients with Barthel Index above 80. The model of TIA service we implemented based on ultra-rapid stroke physician assessment and carotid ultrasound investigation is feasible and clinically valid. Indirect evidence suggests that it reduced the rate of expensive TIA/minor stroke hospital admissions.

Abstract

In Italy the vast majority of TIA and minor strokes are seen in the A&E. Early diagnosis and management of TIA and minor stroke in this setting is habitually difficult and often lead to cost-ineffective hospital admissions. We set up an ultra-rapid TIA service run by neurovascular physicians based on early specialist assessment and ultrasound vascular imaging. We audit the clinical effectiveness and feasibility of the service and the impact of this service on TIA and minor strokes hospital admissions. We compared the rate of TIA and minor stroke admissions/discharges in the year before (T0) and in the year during which the TIA service was operating (T1). At T1 57 patients had specialist evaluation and 51 (89.5 %) of them were discharged home. Two (3.5 %) patients had recurrent symptoms after discharge. Seven had a pathological carotid Doppler ultrasound. Four of them had hospital admission and subsequent carotid endoarterectomy within a week. Taking the whole neurology department into consideration at T1 there was a 30–41 % reduction in discharges of patients with TIA or minor stroke. Taking the stroke unit section into consideration at T1 there was a 25 % reduction in admissions of patients with NIHSS score <4 and 40 % reduction in admissions of patients with Barthel Index above 80. The model of TIA service we implemented based on ultra-rapid stroke physician assessment and carotid ultrasound investigation is feasible and clinically valid. Indirect evidence suggests that it reduced the rate of expensive TIA/minor stroke hospital admissions.
