RESUMO
The aim of this study was to determine and identify the factors associated with shortening or lengthening time interval from stroke onset to performance of computed tomography (CT) scan in stroke patients admitted to three French emergency departments. All suspected stroke patients were eligible (n = 317). The time intervals between stroke onset and presentation to the emergency department and between CT scan request and CT scan performance were determined. Twelve variables likely to influence time interval before presentation to the emergency department, and five variables likely to influence time interval before CT scan performance were evaluated using stepwise regression analysis. Of the 317 patients included in the study, the mean time interval from stroke onset to CT scan performance for 180 patients was 7 hours 46 minutes (466 minutes). The mean time interval between stroke onset and presentation to the emergency department was 4 hours 36 minutes (276 minutes), varying according to the study site, level of initial severity, medical contact before admission, witnesses at stroke onset, and mode of transportation. The mean time interval between request and CT scan performance was 2 hours 14 minutes (134 minutes), varying upon the site, hour of CT scan request, type of stroke and level of severity at admission. It is concluded that current delays in stroke management are often incompatible with early treatment. The public needs to be informed and admission procedures reorganized. Improved response to the urgency of ischaemic stroke is required as well as direct access to the scanner during periods of scheduled use.
