摘要

This study evaluates the difference in service time before and after the implementation of the six sigma initiative in the operation rooms (OR). Nursing staff in OR used the structured data collection forms to record data from six processes check points for surgical patients in a medical center during the enrollment period. Patients were assigned to three groups based on their staying time in OR (＜=120, 121-240, ＞241 minutes). This study enrolled 1,692 patients in the baseline group (from March 25, 2005 to May 15, 2005) and 1,692 patients in the post-test group (from June 27, 2005 to August 7, 2005). The differences in service efficiency were compared using the t-test and the chi-square test. The analyses demonstrate that three surgical groups according to staying time achieved reductions of 3.43, 4.77, and 12.98 minutes in OR (p＜0.05). Moreover, turnaround time was reduced by 6.76, 5.3, and 7.02 minutes (p＜0.05), respectively, and employee overtime was reduced by 6.01, 10.07, and 20 minutes, respectively (p＜0.05). The study supports that the six sigma technique can effectively reduce patient stay in OR, improve turnaround time of OR, and can significantly reduce staff overtime. This study provides empirical results for use by managers in peer hospitals, surgical departments, and for administrative purposes.
