Time to hospital admission and start of treatment in patients with ischemic stroke in northern Italy and predictors of delay.

BACKGROUND AND PURPOSE: Early treatment (i.e. thrombolysis) is crucial for a successful care of ischemic stroke. In the management of stroke, two phases are crucial: the pre-hospital and the in-hospital interval. This work investigated factors influencing pre- and in-hospital delay in a large geographic area of Northern Italy. METHODS: Enrolled were patients presenting with ischemic stroke in four administrative districts of Northern Italy (Como, Lecco, Sondrio and Varese) over a 4-month period. Pre-hospital time and in-hospital time with single management steps were recorded prospectively. Age, gender, recruiting hospital, EMS transport and triage codes, clinical severity and thrombolytic treatment were also recorded. Univariate and multivariate analysis of factors predicting pre- and in-hospital delay were performed. RESULTS: Median pre-hospital time and in-hospital time were, respectively, 120 min (interquartile range, IQR 62-271) and 150 min (IQR 80-214). Pre-hospital time was halved in patients hospitalized via EMS (p<0.001) and clinically more severe (p<0.001). At multivariate analysis, transport code was associated with delay at any time (p<0.05). CONCLUSIONS: EMS use and transport code predicted treatment delay in patients with ischemic stroke. A more intensive use of EMS and high urgency codes could help increase the number of stroke patients treated appropriately.

Stroke management in northern Lombardy: organization of an emergency-urgency network and development of a connection between prehospital and in-hospital settings.

Stroke is the leading cause of disability in adulthood, and the principal aim of care in cerebrovascular disease is the reduction of this negative outcome and mortality. Several studies demonstrated the efficacy of thrombolytic therapy in ischemic stroke, but up to 80% of cases could not be treated because the diagnostic workup exceeds the time limit. In this article, we described the design of a study conducted in the northern Lombardy, within the district of Sondrio, Lecco, Como, and Varese. The awaited results of this study are reduction of avoidable delay, organization of an operative stroke emergency network, and identification of highly specialized structures. The study schedules education and data registration with implementation and training of acute stroke management algorithms. The use of standardized protocols during prehospital and in-hospital phase can optimize acute stroke pathways. The results of this study could contribute to the assessment of an effective and homogeneous health system to manage acute stroke.
