Abstract

The qualified treatment of acute stroke strongly depends upon the emergency medical system (EMS), those of the initial actions of patient’s family, activities of emergency medical technician, and the transportation to medical doctors. Tokyo Metropolitan Stroke Association Council has been organized to evaluate the quality of EMS for acute stroke care in Tokyo City and carried out a one week study by using questionnaires given to emergency technicians and to hospitals at 2010 and at 2012. We verified these questionnaires from the point of enlightenment for citizens and of the accuracy for judgment of the emergency technician for acute stroke. The interval between the onset and ambulance call, which is the good indicator of the initial actions of patients’ family was shortened from 42.0 minutes at 2010 to 23.0 minutes at 2012. However, the interval between the ambulance call to the hospital, which is one of the indicator of the quality of EMS became longer from 40.0 minutes to 42.0 minutes. The sensitivity, specificity, and pseudo-negative cases, which are diagnosed as acute stroke by the medical doctors without the evaluation as acute stroke by the emergency technician are reviewed. The sensitivity, and the specificity was 82.4% and 97.9% at 2010, 70.8% and 98.4%, at 2012, respectively. And the cases of pseudo-negative are increased from 64 to 100. For the physicians and nurses working in the emergency room (ER), Japan Triage & Acuity Scale (JTAS) and Immediate Stroke Life Support (ISLS) gradually popularized for the diagnosis of acute stroke.
