Data source
TSR, launched in 2006, is a multi-center stroke registry system with
participation of 38 hospitals (16 medical centers, 20 regional
hospitals, and 2 local hospitals) in Taiwan20. Trained
personals at participation hospitals were in charge of registry tasks
and the follow-up data collection. The registration data contained
demographic profiles, information on National Institute of Health Stroke
Scale (NIHSS), hospitalization records, and discharge information.
Telephone contacts were performed at 1, 3, 6, and 12 months after stroke
to collect follow-up information, including deaths. The informed
consents were obtained from all patients before being included in the
registry program. This study was performed in compliance with guidelines
of the Declaration of Helsinki and approved by the Institutional Review
Board [CMUH102-REC1-086 (CR3)].
