Abstract:
Objective To investigate the application of CUSUM (cumulative sum control chart) curve in cardiac clinical teaching of resident surgeon education.Methods We chose a surgeon of 10years work experience of attending the preparation operation of internal mammary artery as control reference (standard group,28 patients) and a resident engaged in professional clinical cardiac work no more than 5 years as group 1,a professional training physician engaged in cardiac surgery clinical work more than 5 years as group 2 and took 40 patients' data respectively from the two groups' preparation of internal mammary artery operation.And then we recorded the postoperative mammary artery flow,internal mammary artery preparation time and adverse events data and made statistics analysis with SPSS 19.0,and CUSUM curve with Matlab R2012b polynomial curve.Results When the density of operate interval and the operate numbers came to about 25 cases,the polynomial eurve's slope rate went up to 0,regardless the surgeons' experience,CUSUM value was accumulated from 66 to 76,and overcame the learning curve successfully.However,when the density of operate interval did no reach the standard,the surgeon's CUSUM ploynomial cmwe slope rate never reached to 0,and can't overcome the learning curve.Conclusion CUSUM curve gives a clear quantitative indicator to the cultivation of clinical physician,and makes teaching teachers can understand the young physicians' learning process,so as to change the teaching plan,help young physicians cross the learning curve as soon as possible.
