ABSTRACT
Objective To analyze the current situation of the quality of critical value management in ultrasound department,and to explore the application and effect of PDCA cycle method in critical value management.Methods The quality status of emergency data during the period from January 2015 to January 2019 after the PDCA cycle was adopted was analyzed.The PDCA cycle method was applied to improve the overall quality.The reporting rate,awareness rate,qualified rate of writing,and timely rate of clinical treatment were compared before and after the PDCA cycle was adopted to evaluate the effect of PDCA cycle method.Results From January 2015 to January 2019,the reporting rate was 96.4％,98.0％,94.5％,and 96.7％,the awareness rate of critical value was 63.2％,78.6％,84.8％,and 92.2％,the qualified rate of writing was 70.4％,77.2％,85.3％,and 94.0％,and the timely rate of clinical treatment was 50.9％,71.7％,81.1％,and 85.5％,respectively.The awareness rate,the qualified rate of writing,and the timely rate of clinical treatment were significantly improved (x2=12.464,38.184,52.926,all P ＜ 0.05).Conclusion PDCA cycle method can improve the quality of emergency management in ultrasound department.
ABSTRACT
Objective@#To investigate the correlation between the maximum elastic modulus(Emax) of breast cancer obtained by shear-wave elastography (SWE) and immunohistochemical profiles.@*Methods@#One hundred and sixty patients with 171 pathologically proven breast lesions were included in this study. All of them underwent conventional ultrasound and SWE examination before surgery. The Emax and maximum diameter were obtained. Histologic grade, immunohistochemical profiles ER, PR, HER-2, Ki-67 and molecular subtypes were recorded according to pathological results after surgery. The correlation between Emax and tumor size, histological grade, ER, PR, HER-2, Ki-67 and molecular subtypes were analyzed.@*Results@#①There was a positive correlation between the tumor size with Emax(r=0.510, P<0.05); ②The Emax of tumors with HER-2 positive expression were higher than that with HER-2 negative expression(P<0.05), the Emax of tumors with Ki67 high expression were higher than that with Ki67 low expression (P<0.05); ③There were significant differences in Emax between different molecular subtypes(P<0.05), the Emax of HER-2 positive tumor was the highest, followed by those of Luminal B tumor, triple-negative and Luminal A tumor; ④Multiple linear regression indicated that tumor size was the strongest pathologic determinate of Emax value(P<0.05), its standardized partial regression coefficient was 0.500, and HER-2 also had significant influence on Emax value of tumor(P<0.05), the standardized partial regression coefficient was 0.237.@*Conclusions@#Some prognosis immunohistochemical feature of breast cancer showed association with the Emax. Breast cancers with higher Emax at shear-wave elastography had poor prognostic features. To some extend, the value of Emax can reflect the biological characteristics of breast cancer, SWE may provide a certain imaging basis for the prognosis of breast cancer and the choice of treatment plan.
