Abstract Objective To establish central venous catheter infection risk assessment tool for measuring of Chinese intensive care unit(ICU)patients with central venous catheter infection risk.Methods Using the Delphi method,Risk Scoring System for Central Venous Catheterization Associated Bloodstream Infections for reference,with nursing safety and risk management theory as the framework,the expert consultation questionnaire was formed on the basis of review relevant literature.Twenty-five experts were selected for two rounds of expert consultation,and the items of the scale were screened to form the final risk assessment tool for the patients in ICU.Results The expert′s positivity was high and the response rates of the two-round consultation were 83.3% and 100%,the coefficient of the expert′s authorities Cr were 0.89 and 0.88,after the two-round consultation,Kendall′s W was 0.331(P＜0.001).Finally,ICU patients central venous catheter infection risk assessment tool included 4 first-level indicators,19 second-level indicators.Conclusion The reliability and authority of ICU patients central venous catheter infection risk assessment tool established based on the Delphi method is relatively high.It can provide a reference for clinical nurses to evaluate ICU patients central venous catheter infection risk and lays a foundation for testing the reliability and validity and evaluating the predictive ability of the scale.

Key words： Intensive care unit Central venous catheter infection Risk assessment model Delphi method
