Objective To establish a sensitive index system for the risk assessment of venous catheter bloodstream infection in lung cancer patients based on the Delphi method, providing scientific and accurate assessment tools for nursing staff to improve nursing quality and reduce the risk of infection. Methods Through literature review, relevant research results and guidelines were sorted out to understand the assessment standards and methods of venous catheter bloodstream infection. Data were extracted to construct the framework of a sensitive index system for nursing quality in the risk assessment of venous catheter bloodstream infection in lung cancer patients. The final index system was formed by using the Delphi expert inquiry method. Results In both rounds of inquiries, the effective recovery rate of the expert questionnaires was 100%, and the positive coefficient of the experts was also 100%. The authority coefficients were 0.866 and 0.898 respectively, and the coordination coefficients ranged from 0.347 to 0.911. The final constructed sensitive index system for the risk assessment of venous catheter bloodstream infection in lung cancer patients included 4 first-level indicators, 15 second-level indicators, and 28 third-level indicators. Conclusion The construction of a scientific and comprehensive sensitive index system for the risk assessment of venous catheter bloodstream infection in lung cancer patients can comprehensively evaluate the infection risk of patients and provide scientific guidance and basis for nursing intervention and management.
