Design Compile a questionnaire, conduct a questionnaire survey and test the reliability and validity of the questionnaire. Methods The initial questionnaire was formed based on the theory of KAP, combined with literature review and Delphi expert correspondence method; a questionnaire survey was conducted among 334 ICU nurses in five tertiary hospitals, and the reliability and validity of the questionnaire were tested and a formal questionnaire was compiled. Results The ICU nurses' CVC maintenance KAP questionnaire included 31 items in three dimensions of knowledge, attitude and behaviour. The item content validity (I‐CVI) and questionnaire content validity (S‐CVI) were 0.889 ~ 1.000 and 0.974, respectively. Exploratory factor analysis extracts three common factors (dimensions), the cumulative variance contribution rate is 65.656%, the Cronbach'α coefficient of the total questionnaire is 0.843, and the Cronbach's α coefficients of the three dimensions of KAP are 0.754, 0.887 and 0.940, respectively. The split‐half reliability is 0.816. The test–retest reliability of the total questionnaire is 0.813. Conclusion The ICU nurses' CVC maintenance KAP questionnaire has good reliability and validity, stable results, comprehensive coverage, and high feasibility.
