Therefore, many prediction models were developed to identify high risk patients, but they had manyshortcomings. In addition, it is still unknown about the performance of these models if they are used inTaiwan. The reliability of these models has not been evaluated well. On the other hand, the distribution ofsubtypes of ischemic stroke among patients in western countries was different from that in eastern countries,and thus it was speculated that the useful prediction tools to identify high risk patients with TIA could bedifferent among eastern and western countries.We therefore propose a three-year study with the following objectives:1. to external validate the previously developed prediction models, such as ABCD2、ABCD2I、ABCD3、ABCD3I, with TIA patients who visited the emergency department of National Taiwan UniversityHospital.2. to evaluate the reliability of the ABCD3 prediction model by observing interobserver agreement andcomparing the differences.3. to develop a new prediction tool which fits the TIA patients in Taiwan best, to compare the performanceof the new tool with that of previously developed prediction models, and to perform multicenterprospective validation.中風短暫缺血性腦中風預測模型信度效度驗證stroketransient ischemic attackprediction modelreliabilityvalidation
