TRIAGETRIAGE
Triage is used in medical Triage is used in medical emergencies, as a system to sort emergencies, as a system to sort the injured so that the greatest the injured so that the greatest number of patients can be helped. number of patients can be helped. In medical emergency situations In medical emergency situations where there are more injured where there are more injured people than there are medical people than there are medical resources to care for them, triage resources to care for them, triage allows doctors or other health care allows doctors or other health care professionals to decide which professionals to decide which people can be helped the most, people can be helped the most, and how to help them efficiently.and how to help them efficiently.

The purposes are as follows :The purposes are as follows :1.1. Base on information management ,the Base on information management ,the
information system is applied in triage of the information system is applied in triage of the Emergency Department to generate patients’ Emergency Department to generate patients’ datadata
2.2. Exploration of correlation between triage and Exploration of correlation between triage and abnormal diagnosis ;abnormal diagnosis ;cluster analysiscluster analysis conducted conducted on variables with clinical meaningson variables with clinical meanings
3.3. Establishing triage abnormal diagnosis clusters Establishing triage abnormal diagnosis clusters with with hierarchical clustering (Ward ’method)hierarchical clustering (Ward ’method) and and partitioning clustering (K-means algorithm);partitioning clustering (K-means algorithm); obtaining correlation law of abnormal diagnosis obtaining correlation law of abnormal diagnosis with with decision treesdecision trees
4.4. Improving consistency of triage with data Improving consistency of triage with data mining ;offering quantified and scientific rules for mining ;offering quantified and scientific rules for triage decision -making in the hope of serving as triage decision -making in the hope of serving as a foundation for future researchers and clinical a foundation for future researchers and clinical examinationexamination
