The Japanese Standard Stroke Registry Study (JSSRS) group (chief investigator: S. Kobayashi) developed new software for its acute stroke database. In our institute, this software was applied within a medical records database system that functioned in a local area network (LAN). From January 1, 2000, to January 31, 2002, 2,068 stroke patients were registered in the JSSRS database, and 1,731 patients' data were confirmed. About 70 patients were registered monthly, and cumulative cases with unconfirmed data were not increased but changed up to a mean 75 cases per month. The third section (medical record manager) should control continuous registration of stroke patients and confirmation of input data.
The JSSRS database was useful for confirming classification of disease, patients' history, and clinical course for other forms in the medical records database. According to the confirmed stroke database, clinical categories of acute brain infarction were classified into cardiogenic embolism in 28.0%, atherothrombotic stroke in 27.4%, and lacunar stroke in 35.3%. Time from stroke onset to admission was within 3 hours in 36%, and within 6 hours in 48%. Accuracy of the stroke database could improve after the introduction of JSSRS database software.
An acute stroke databank based on the JSSRS database could be valuable for establishing evidenced based medicine (EBM) for stroke management and planning of new strategy for acute stroke. In addition, input data for the JSSRS database is useful for confirming and establishing a medical records database.
