[Asia Economy Reporter Lee Gwan-joo] Professor Bae Hee-jun of the Department of Neurology at Bundang Seoul National University Hospital announced on the 1st that the number of patients registered in the 'Domestic Multicenter Stroke Cohort Study (CRCS-K)' has reached 100,000. This is the largest stroke registry worldwide that classifies patients by cause based only on those verified through brain imaging.

CRCS-K was initiated to develop specific and standardized clinical guidelines for the prevention, diagnosis, treatment, and rehabilitation of stroke. Currently, it is operated with support from the Korea Disease Control and Prevention Agency's National Institute of Health, and researchers from a total of 19 hospitals, including Bundang Seoul National University Hospital, have registered over 100,000 stroke patients over 14 years of effort.

CRCS-K not only registers patients verified by stroke specialists analyzing brain imaging results according to stroke onset causes but also conducts follow-up observations for at least one year for most discharged patients. Due to these factors, the data reliability and quality are very high, resulting in the publication of over 160 SCI papers, and the registry has been utilized in stroke treatment guidelines both domestically and internationally.

Professor Bae, the principal investigator, said, "I would like to express my deep gratitude to the dedicated efforts of researchers at each institution and to the patients who agreed to register in the registry, enabling us to recruit 100,000 stroke patients," adding, "We will continue to do our best in research utilizing CRCS-K so that the efforts of researchers and patients are not in vain."

The achievements of CRCS-K will be reported at the International Stroke Conference of the Korean Stroke Society (ICSU 2022) on the 10th at the Grand Walkerhill Hotel in Seoul. The hospitals participating in CRCS-K include ▲Keimyung University Dongsan Medical Center ▲Korea University Guro Hospital ▲Nowon Eulji University Hospital ▲Daejeon Eulji University Hospital ▲Dongguk University Ilsan Hospital ▲Dong-A University Hospital ▲Bundang Seoul National University Hospital ▲Seoul Medical Center ▲Soonchunhyang University Seoul Hospital ▲Yeungnam University Hospital ▲Ulsan University Hospital ▲Uijeongbu Eulji University Hospital ▲Inje University Ilsan Paik Hospital ▲Chonnam National University Hospital ▲Jeju National University Hospital ▲Chung-Ang University Hospital ▲Chungbuk National University Hospital ▲Hallym University Sacred Heart Hospital ▲Hallym University Chuncheon Sacred Heart Hospital (in alphabetical order), totaling 19 hospitals.
