The Investigation Of Knowledge Of Venous Thromboemblism?Willingness And Behavior To Participate In Prevention Of Thrombus Based On The Orthopaedic Inpatients

Objective:Based on the theory of "patient participation in patient safety",this study constructed the questionnaire of venous thrombosis knowledge,willingness and behavior to participate in the prevention of thrombus in orthopaedic patients.To investigate the knowledge level of venous thrombosis,and the willingness as good as behavior of the patients to participate in the prevention of thrombus in orthopaedic patients.To provide theory and data foundation for clinical work,guiding clinical nurses take targeted health education.It is aimed to promote patients participate actively in thrombosis prevention,and reduce the incidence of venous thrombosis in orthopaedic patients,and promote the development of patient safety culture in China at same time.Method:1.Delphi method: based on the results of literature review and qualitative interview,constructing the preliminary draft of questionnaire,and revising further by Delphi method.The reliability and validity of the questionnaire was tested by clinical pre-survey.2.Cross-sectional investigation: useing convenience sampling,selected the orthopaedic patients hospitalized in top three hospital in Nanchang City as the objects of investigation from December 2017 to February 2018.The questionnaire survey was executed by a orthopedic patient general information questionnaire and the self-made orthopedic patients venous thrombosis knowledge and participation in thrombus prevention willingness and behavior scale,and this study collected total 222 valid questionnaires.3.Statistical method: useing spss software to analyze information,the (?)±S,frequency and percentage to be statistical description,statistical analysis by t test,analysis of variance,multivariate regression analysis and pearson correlation.Result:1.Through two rounds of expert letters,the questionnaire were determined three first-level indicators,included the knowledge of venous thrombosis,the willingness and the behavior of participation.The knowledge of venous thrombosis include conception,risk factors,clinical manifestation,outcome,prevention of 5 second-level indicators,with 12 items.Participation willingness and behavior have 3 second-level indicators,included decision-making participation,care participation and appeal partIcipation,with 8 items and 10 items respectively.The cronbach's coefficient of each secondary index is 0.836~0.899,the split-half reliability coefficient is 0.754~0.823,I-CVI was 0.867~1.000,S-CVI was 0.927,the reliability and validity were good.2.The average of knowledge was(20.31±5.34),which was in lower level,multiple regression analysis show that the score were affected by education background,occupation,inpatient ward and treatment stage.The mean score of willingness was(31.05±4.56),which was in the middle level,multiple regression analysis show that the scores were affected by the inpatient ward and treatment stage.The average score of participation behavior was(41.07±4.49),which was in the mid to upper level,multiple regression analysis show that the scores were affected by education background,inpatient ward and treatment stage.The Pearson correlation analysis show that there was a positive correlation among the knowledge of venous thrombosis,participation willingnes and behavior in orthopaedic patients,the correlation coefficient was0.233,0.643,0.271,respectively,the difference was significant statistically.Conclusion:1.The method of questionnaire construction was scientific and reasonable,and the reliability and validity of it are good.so,the questionnaire can be used to investigate the knowledge level of venous thrombosis,the willingness and behavior level to participate in prevention venous thrombosis in orthopedic patients.2.The level of knowledge venous thrombosis in orthopaedic patients was low,and the scores of the low-levels of education,workers and farmers were significantly lower than other groups.The nursing staff should pay attention to them and take effective health education to improve the patients knowledge level.Patients participation willingness and behavior were in the medium level all,Moreover,the social demographic characteristics were little effect on the patients.The patient of different social ba-ckgrounds,and their willingness to participate is similar to that of the patients with different social backgrounds.The scores of knowledge,participation willingness and behavior of the patients in the sub-specialist area of orthopedics were higher than those in the comprehensive orthopedic department,which indicated that the management of the sub-specialist ward was beneficial to improve the effect of health education and the quality of nursing care.3.The knowledge of venous thrombosis in orthopaedic patients was positively correlated with their participation willingness and behavior.Increasing the level of knowledge of venous thrombosis in orthopedic patients could improve effectively their willingness and behavior to participate in prevention,thus reducing the incidence of venous thrombosis in orthopedic patients.
