The pre-hospital stroke type discrimination system `` JUST Score'' developed in 2018 by a research group of Professor Shinichi Yoshimura of the Department of Neurosurgery, Hyogo College of Medicine, and Professor Takeshi Morimoto of the Department of Clinical Epidemiology, can detect patients with suspected stroke. It is used as a support system for medical staff such as emergency teams to be evaluated first to instantly predict the type of disease and transport it to an appropriate treatment facility.
The accuracy of the diagnosis of such a pre-hospital stroke prediction model has already been widely studied all over the world, but this time, the group is the first attempt in the world to "introduce a pre-hospital stroke type discrimination system". We worked on "introduction of machine learning" and "demonstration of the effect of shortening the time to treatment when using the pre-hospital stroke type discrimination system", and reported that the results were both published simultaneously in international medical journals. ..
First, since the "JUST Score" is created based on past research data, it may be delayed in responding to changes in the characteristics of various regions and the background of the times.To solve this problem, we have developed a machine learning model "JUST-Machine Leaning" that reflects the latest regional data in real time (makes it AI).As a result, regardless of the type of stroke, "JUST-Machine Leaning" had higher discriminating ability than "JUST Score", and improved diagnostic accuracy was observed.
Next, before and after the introduction of the "JUST Score", rescuers compared and analyzed the results of transportation of patients with suspected stroke and how the results of treatment after transportation changed.As a result, it was found that the use of "JUST Score" has the effect of reducing the number of negotiations with the hospital of the ambulance crew and shortening the transportation time (time from onset to treatment).
Based on the above, the "JUST Score" increases the possibility that stroke patients will receive appropriate treatment at an early stage, and as a result, contributes to improving the prognosis of patients. Studies aimed at optimizing the "JUST Score" will continue. Is to be continued.
