Abstract
Introduction: cerebrovascular disease is the most frequent cause of death in argentin in 2004, it cause 7.5% of total deaths. The American Heart Association proposes using Cincinnati Prehospital Stroke Scale (CPSS) and Los Angeles Prehospital Stroke Screen (LAPSS) to evaluate cerebrovascular cases.
 Objective: is to evaluate the awareness of knowledge of these scales between doctors working in emergency rooms and prehospital consultation and range of usefulness of these scales.
 Material and Method: Observational and prospective survey of 569 doctors from the Argentinian provinces of Santa Fe, Rios, and Chaco from December 2008 to March 2009.
 Results: One third of doctors declared to know the scales, but 8.4% could enumerate CPSS points, while 1.9% could enumerate LAPSS points with 0.7% remembered both CPSS and LAPSS points. Those who remembered either one or both scales felt safer evaluating a possible stroke (p= 0.02) .Those who felt more hesitant where the doctors who a described more benefits to the scales (p= 0.0003). Non specialists considered scales more useful
 Conclusion: Both scales were valued by doctors to diagnose patients with possible stroke. We try to stress the need of a widespread coverage of these scales to improve the initial approach for managing these patients.
 Keywords: stroke, Los Angeles Prehospital Stroke Screen, Pre-hospital Stroke Scale, emergency room, doctors on call.
Highlights
Stroke - CVA, stroke, or stroke in the English-speaking literature - it is a frequent and increasing pathology, among other reasons for the increase in the life expectancy of the population, and due to difficulties in controlling cardiovascular risk factors
When asked about the degree of safety they experienced when evaluating a patient with possible stroke, 53.8% (306) were showed moderately safe, 38.5% (219) expressed feeling very safe and 7.7% (44) stated feel insecure. 32.3% (184) expressed knowing at least one of the scales under study; only 8.4% (58) could correctly mention Cincinnati Prehospital Stroke Scale (CPSS), 1.9% (11) did with Los Angeles Prehospital Stroke Screen (LAPSS) and 0.7% (4) correctly mentioned both
CVA is a common pathology;the majority of the surveyed physicians stated that they felt insecure or moderately safe when evaluating patients who could potentially suffer from this pathology.Due to the fact that the surveys were carried out in person and in person, mostly in the workplaces of the subjects, there is the possibility that the degree of insecurity experienced by them is even greater than that reported
Summary
Stroke - CVA, stroke, or stroke in the English-speaking literature - it is a frequent and increasing pathology, among other reasons for the increase in the life expectancy of the population, and due to difficulties in controlling cardiovascular risk factors It is an important cause of morbidity and mortality. The currently available treatments continue to be hardly applicable to most patients who suffer from it, due to in part to the limited "therapeutic window" for its use, as well as difficulties and delays in the frame detection Such is the importance of this pathology that the American Heart Association (AHA) in its 2005 guide on Cardiovascular Resuscitation, proposes
