RESUMO
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.
