Abstract
Objective To investigate the time limit of six sigma approach in optimizing the chronergy of green channel for image examination. Methods A total of 600 patients with suspected acute ischemic stroke and examined by computed tomography (CT) during January-May 2015 were selected into control group, and the time of each stage was analyzed to find out the key factors to prolong the time of the patient's waiting time. The improvement measures were put forward for shortening the whole time of CT examination. After the improvement measures were implemented, another 600 patients who were diagnosed as suspected acute ischemic stroke by CT during Jan-May 2016 were selected into experimental group. Residence time in the green channel of CT examination (CT scanning, the end of CT scanning-CT report, total residence time of target<30 min) was improved by applying the 5 step method in the six sigma management system. The qualified rate of residence time was compared between two groups. Results Before improvement, the average time of the whole imaging examination was (40±7) min;after improvement, the average time of the whole imaging examination was (28±2) min (P=0.001). The duration of CT scanning was shortened from (15±4) min to (10±2) min (P=0.006); the duration of the end of CT scanning-CT report was shortened from (25±5) min to (23±3) min (P=0.006). The qualified rate of residence time in the green channel of image examination was improved by 13.67%. Conclusion The six sigma management system can significantly shorten the residence time in the green channel of image examination and effectively improve rescue efficiency in emergency patients with stroke.关键词
