The project aimed to improve the poor identification upon patients. Through overall investigation, the major cause which results in the harmful events or medical disputes potentially includes (1) loose management of patient identification band, (2) patients' poor cognition about their safety, and (3) nursing staffs' poor identification checking. Through empirical surveys, analyzing upon the current situation and reviewing in the literature, proposed solutions as following: 1) Set up SOP (Standard of Operation Procedure) about the identification band, and then secure the material to be water-proof ones. 2) Educate patients' concept about the safety and educate nursing staffs with in-service training in the manner of patient identification. 3) Enhance check-up for rewards and penalty upon nursing staffs. Through actuating above measures, the patient identification rate increases from 75.3% to 95.6%. The results reveal that the project improves the patient identification efficiently.
