Abstract:
Objective To discuss the application of Six Sigma management in quality reinforcement of coronary artery CTA,in order to improve patients satisfaction regarding medical nursing.Methods 1 388 cases who had received coronary artery CTA from July to December 2011 in Peking University Shenzhen Hospital were randomly divided into the observation group of 456 cases and the control group of 476 cases.The patients in control group received conventional CT examination while the observation group received Six Sigma management CT examination.Two groups' score of image quality,defect rate and satisfaction were compared.Results The score of image quality was (4.17 ±0.72) in the observation group and (3.04 ± 1.07) in the control group.The difference was statistically significant (t =8.674,P ＜ 0.01).The defect rate was 0.74％ in observation group,lower than 4.86％ in the control group,and the difference was statistically significant (x2 =373.14,P ＜0.01).Patients' satisfaction was 95.60％ and doctors' satisfaction was 98.00％ in the observation group,both were higher than those in the control group (88.60％ and 92.00％,respectively),and the differences were statistically significant (x2 =11.91,7.58,respectively; P ＜ 0.01).Conclusions Application of Six Sigma management can effectively enhance the quality of coronary artery CTA and increase the quality and efficiency of work.
