Analysis of the prehospital life support and consideration for stroke bypass in Tokyo

Abstract

Background and Purpose: To introduce the stroke bypass system in Tokyo for the direct transfer of the patients suffered from emergent large vessel occlusion (ELVO) to endovascular capable center, the present status of the Tokyo Emergency Medical Service (TEMS) was confirmed. Methods: We analyzed eight representative prehospital stroke scales (PSS), TEMS guideline, Prehospital Stroke Life Support (PSLS) guideline of the Japanese Society for Emergency Medicine (JSEM). Results: Enough patient’s information to calculate some PSS had been already collected according to TEMS guideline as equal to PSLS. Conclusion: Stroke bypass system could be already performed in Tokyo if TEMS crews could calculate the PSS to predict ELVO with high precision. To solve this problem, we developed an application to calculate the PSS automatically when they enter the patient’s information on it.
