持续干预措施对急诊科血培养标本质量的影响

Influence of Continuous Intervention Measures on the Quality of Blood Culture Samples in Emergency Department

目的探讨持续干预措施对急诊科血培养标质量的影响。方法选择2019年1月至2019年8月持续干预前急诊科血培养标本1 715份,选择2019年9月至2020年3月持续干预后急诊科血培养标本1 938份,评估持续干预前后血培养标本的送检率、污染率和阳性率。结果持续干预后,血培养标本送检率为99.12%,高于持续干预前的98.02%(P <0.05)。持续干预后,血培养标本污染率为0.88%,低于持续干预前的1.98%(P <0.05)。持续干预后,血培养标本阳性率为13.69%,与持续干预前的12.85%比较无统计学差异(P>0.05)。结论持续干预措施可提高急诊科血培养标本的送检率,降低污染率,值得临床推广应用。

Objective To explore the influence of continuous intervention measures on the quality of blood culture samples in emergency department.Methods 1715 blood culture samples from January 2019 to August 2019(before continuous intervention)in emergency department were selected,and 1938 blood culture samples from September 2019 to March 2020(after continuous intervention)in emergency department were selected.The submission rate,pollution rate and positive rate of blood culture samples before and after continuous intervention were evaluated.Results After continuous intervention,the submission rate of blood culture samples was 99.12%,higher than 98.02%before continuous intervention(P<0.05).After continuous intervention,the pollution rate of blood culture samples was 0.88%,lower than 1.98%before continuous intervention(P<0.05).After continuous intervention,the positive rate of blood culture samples was 13.69%,which had no statistical difference with 12.85%before continuous intervention(P>0.05).Conclusions Continuous intervention can improve the submission rate of blood culture samples in emergency department,and reduce the pollution rate,which is worthy of clinical promotion and application.
