Abstract 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⁃Ⅲ hospital 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.
