摘　　要：目的:探讨基于循证证据的降低血培养标本污染率干预方案在血液肿瘤患儿临床实践中应用效果。方法:根据“6S”模型自上而下进行文献检索,对检索到的文献进行文献质量评价和证据可用性评价,形成降低血培养标本污染率的审查指标。选取2021年12月1日—31日在武汉市某三级甲等医院儿童血液肿瘤科工作的18名护理人员为审查对象进行循证实践。结果:最终汇总了12条证据、11条审查指标。循证实践后,血培养标本污染率由4.78%降为1.79%,护理人员对证据的知晓率提高,审查指标的符合率有所提高,差异均有统计学意义(P<0.05)。结论:基于证据的质量改进可降低血培养标本的污染率,提高护士对审查指标的知晓率及审查指标符合率。Objective:To explore the effect of evidence-based intervention program to reduce the contamination rate of blood culture samples in the clinical practice of children with blood tumors.Methods:According to the"6S"model,the literature was searched from top to bottom,and the literature quality and evidence availability were evaluated to form a review index for reducing the contamination rate of blood culture samples.From 1 to 31 December 2021,18 nursing staff working in the children's hematology and oncology Department of a Grade-Ⅲhospital in Wuhan were selected as the subjects for evidence-based practice.Results:Finally,12 pieces of evidence and 11 review indicators were summarized.After evidence-based practice,the contamination rate of blood culture samples decreased from 4.78%to 1.79%,the awareness rate of nursing staff to the evidence increased,and the conformity rate of review indicators increased,with statistical significance(P<0.05).Conclusion:The quality improvement based on evidence can reduce the contamination rate of blood culture samples,improve the awareness rate of nurses and the conformity rate of examination indicators.
