Abstract
We have developed computer based stroke database for acute stroke patients in 1999–2001 by the fund of Ministry of Health, Labour and Welfare Organization. We started registration of stroke since 2001 and accumulated more than 50,000 stroke cases until 2009. The Japanese Stroke Databank was established in Japanese Stroke Association since 2002. This databank is using global standard for evaluation of stroke diagnosis (NINDS 3), severity of stroke (NIHSS, JSS) and prognosis (modified Rankin Scale). Now, 173 institutes joined Japanese Stroke Databank.
Cardiogenic embolism occupied 19.2% among all stroke subtypes. This rate is close to lacunar infarction (22.7%). Because, non-valvular atrial fibrillation is increased with aging in Japan. Hisayama study also revealed cardiogenic embolism markedly increased during 30 years.
We have made historical control data for clinical study of t-PA therapy.
Stroke databank also showed that pre-onset using of antithrombotic agent in the patients of hypertensive hemorrhage was a significant risk for poor prognosis.
This stroke database is useful to made clinical study like as J-STARS.
We are now developing direct transfer system from electric medical record to stroke database. We also developed bidirectional data transfer system between acute hospital and rehabilitation hospital/prehospital care team.
