Abstract:
Objective:To construct a tool to evaluate the knowledge, attitude, and practice of nurses in the prevention of thrombosis related to peripherally inserted central catheter (PICC) .Methods:From December 2022 to April 2023, based on the theory of knowledge, attitude, and practice, a preliminary draft of the PICC-related Thrombosis Prevention Knowledge, Attitude, and Practice Questionnaire for Nurses was formed through systematic literature review, two rounds of Delphi expert consultations, and pre-survey. In May 2023, convenience sampling was used to select 573 nurses from Chinese Academy of Medical Sciences & Peking Union Medical College Hospital as the research subject for a survey to conduct item analysis, validity testing, and reliability testing on the questionnaire.Results:The final version of the PICC-related Thrombosis Prevention Knowledge, Attitude, and Practice Questionnaire for Nurses included 20 knowledge items, 10 attitude items, and 10 practice items. In the content validity of the questionnaire, the average content validity index was 0.984, the overall consensus content validity index was 0.850, and the item level content validity index was 0.857 to 1.000. Exploratory factor analysis extracted three common factors with eigenvalues>1.000, with a cumulative variance contribution rate of 64.540% and factor loadings of 0.450 to 0.908 for each item. The total Cronbach's α coefficient of the questionnaire was 0.895, the half reliability coefficient was 0.947, and the retest reliability coefficient was 0.966.Conclusions:The PICC-related Thrombosis Prevention Knowledge, Attitude, and Practice Questionnaire for Nurses has good reliability and validity, and can be used to evaluate PICC-related thrombosis prevention knowledge, attitude, and practice among nurses.
