BackgroundIntravenous rt-PA is effective in hyperacute ischemic stroke (HAIS) but is administered only in few patients.ObjectivesTo report the thrombolysis rate in our stroke unit using a stroke code (SC) protocol with a prenotification system and to analyze the SC impact on the thrombolysis rate in a systematic review.MethodsWe report, from 2005 to 2009, the intravenous rt-PA rate in our prospective registry of hyperacute strokes suspicions. The systematic review was conducted in searching PubMed and EMBASE for prospective studies reporting thrombolysis rates and their use of a SC. We categorized SC between those with a prenotification by the Emergency Medical Services and those with only an in-hospital SC system.ResultsAmong the 1450 stroke patients hospitalized in our stroke unit, 349 were admitted via the SC protocol as suspicions of hyperacute strokes. Intravenous rt-PA rates were: 12.9% of the ischemic strokes, 36% of the suspicions of hyperacute strokes and 59.6% of the HAIS. We found 23 studies reporting thrombolysis rates ranging from 10.3% to 58% of HAIS. Ten studies gave data concerning the use of a SC in case of HAIS. Thrombolysis rate was higher in hospitals with a prenotification system (54.7%) compared with both those with no specific organization (18.2%) (OR=5.43, 95% CI: 3.84-7.73) and those with an in-hospital restricted SC (37.9%) (OR=1.97, 95% CI: 1.53-2.54).ConclusionsThrombolysis rate of HAIS is improved by a SC, especially when a prenotification system of thrombolysis candidates by Emergency Medical Services to the stroke unit is used.Copyright © 2011 Elsevier B.V.
