(Summary) There are a few stroke specialists in medically under-served areas in Japan. Consequently, in remote area patients may not receive thrombolysis with intravenous recombinant tissue plasminogen activator (iv rt-PA), the standard treatment for acute ischemic stroke. Using a mobile telestroke support system (TSS) that accesses the internet via a smart phone, we implemented iv rt-PA infusion therapy under a drip-and-ship protocol to treat the stroke patients in medically under-served areas. The physicians at the Tokushima Prefectural Kaifu Hospital (TPKH), located in rural Japan, can relay CT or MRI scans and other patient data via their smart phone to off-site stroke specialists. In the course of 34 months, we used the TSS in 321 emergencies. A total of 9 of 188 (4.8%) with acute ischemic stroke, received iv rt-PA infusion therapy using a mobile TSS; in 5 among these (55.6%), we obtained partial or complete recanalization of occluded arteries. None suffered post-treatment hemorrhage and their average NIH stroke score fell from 14.6 at the time of admission to 6.8 at 24 h post-infusion. The drip-and-ship protocol contributed to the safe and effective treatment of the stroke patients living in medically under-served rural areas.

(Summary) Because a specialist in general medical treatment lacked the Kaifu area of South Tokushima absolutely, we forced a limited doctor to many burdens and performed medical treatment while I always carried risks on my back for the disease except the specialty domain. A stroke specialist in particular is an absent medical depopulated area, and it is difficult to perform the rt-PA IV therapy that is a standard therapy for a stroke for the immediate nature period. Using remote video diagnosis treatment supporting system SYNAPSE ERm that was the smartphone application that FUJIFILM developed for the purpose of canceling these, we introduced smartphone and Tokushima Prefectural Kaifu Hospital remoteness medical treatment support system (k-support) by the Internet as area medical treatment support in February, 2013. This system can provide image information and patient information such as CT or the MRI to a tablet phone and the smartphone of Tokushima Prefectural Kaifu Hospital full-time employment doctors and the doctors who support it, and work in a House in real time. In other words, we can obtain necessary information without asking the when and where and can send appropriate instructions, advice to the Tokushima Prefectural Kaifu Hospital medical attendant from a specialist for it. After introduction, the treatment with this system in 58 emergency patients was carried out in seven months until August 31. The example letting the wide area present the smartphone such as this system and a remote medical treatment support system using the Internet in the medical depopulated area is the first trial in this country.

(Summary) A regular neurosurgeon was absent in the southern part II health demographic division of medical services where Kaifu-gun of South Tokushima was located after 2008 and was the present conditions that stroke treatment could not perform enough in comparison with prefecture central part. Furthermore, medical care collapse progressed with the obstetrics and gynecology department and pediatrics closedown at one sweep from the same period and, at the prefectural Kaifu Hospital which was this local nucleus hospital, became hard to maintain the emergency care, and increase of closedown of the emergency outpatient department on Saturday and the emergency transportation to the prefecture central part became remarkable, and it was with a big social problem for Tokushima. A medical difference might occur about stroke medical care in central part and the southern part in Tokushima. We performed the epidemiology survey by stroke patient in the southern II demographic division of medical services (popular name ``Kaifu project'') as a President of University of Tokushima discretion project for this fact-finding individually in the University of Tokushima neurosurgery classroom. In addition, I worked on the enlightenment for inhabitants in Kaifu-gun. ``Local neurosurgical medical treatment part'' was established as a college course financially maintained by private donations of Tokushima University Hospital from November 1，2011． Kaifu Hospital neurosurgery medical treatment was enabled daylong, and emergency correspondence came to be in this way possible. The Kaifu Hospital devises the maintenance policy about Tokushima, local inhabitants, a medical association, a local government and the figure which there should be of ``the new Kaifu Hospital'' for a tsunami now in the plan of the full-scale reconstruction move to the hill in 2015． (Keyword) Medical collapse / Stroke / Neurosurgery (Tokushima University Institutional Repository) ● Metadata: 110018 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1050845762395176832 (Tokushima University Institutional Repository: 110018, CiNii: 1050845762395176832)
