| ObjectiveThis research tries to compile questionnaires on knowledge,attitude and practice of nurses in perioperative prevention of deep venous thrombosis,and to provide a tool for the investigation of the status quo of nurses in perioperative prevention of deep venous thrombosis;to investigate the nursing status of nurses in secondary and tertiary hospitals of Qingdao during perioperative prevention of deep venous thrombosis,and to analyze the influencing factors,so as to establish a specialized training system,to conduct in-depth study of the whole perioperative period and continuous nursing process and provide reference.MethodsBased on the theoretical model of knowledge,attitude and practice,a questionnaire was compiled by ourselves,and the formal questionnaire was determined by Delphi expert inquiry,pre-survey and reliability and validity test.905 perioperative nurses from 23 second and third-level hospitals in Qingdao were stratified and conveniently sampled to investigate the status of prevention of deep venous thrombosis.SPSS18.0 statistical software was used to analyze the survey data.Descriptive analysis was conducted by means of mean ± standard deviation,composition ratio,t-test or variance analysis,multiple linear regression analysis to explore the influencing factors of nurses' knowledge,attitude and behavior in preventing deep venous thrombosis during perioperative period,and Pearson correlation analysis was carried out between the relations of knowledge,attitude and practice.Results1.Part I Questionnaire Development and Evaluation Results(1)After two rounds of expert inquiries,three items with noncompliance with standard assignment were deleted and four items were modified to form the initial questionnaire.(2)The positive coefficients of experts in two rounds of inquiry were 85.00% and 100.00%,respectively;the Kendall's harmonious coefficients of experts were 0.195 and 0.204(P<0.001);and the authority coefficients of experts were 0.836 and 0.849.(3)Four items were deleted after the discrimination,correlation coefficient analysis and reliability and validity test of 197 pre-survey questionnaires were carried out.In content validity analysis,the Item Level Validity(I-CVI)of the total questionnaire was 0.800-1.000,and the Scale Level Validity(S-CVI)was 0.825.In structural validity analysis,the KMO value of each item was 0.824,the Bartlett spherical test value was 3170.304,P<0.001.Twelve common factors with eigenvalues greater than 1 were selected,and the cumulative variance contribution rate was 66.11%.The maximum variance rotation method showed that the load values of each factor ranged from 0.401 to 0.736.In reliability analysis,the intrinsic consistency Cronbach'a coefficient of the total questionnaire was 0.859,and the retest reliability was 0.706.(4)Finally,a formal questionnaire with 40 items in 15 knowledge dimensions,10 attitude dimensions and 15 behavior dimensions was formed.2.Part II Survey results of knowledge,attitude and practice of nurses in preventing deep venous thrombosis during perioperative period.(1)The KAP scores of the questionnaire were 8.40±2.58,38.26±12.53 and 52.79 ±13.10,respectively.The scores of attitude of operating room nurses in preventing DVT were lower than those of surgical nurses(P<0.05).(2)Regression analysis showed that the influencing factors of knowledge score were nurses' gender(?=0.148,P<0.001),education level(?=0.134,P<0.001),professional title(?=0.357,P=0.001),head nurses' professional title(?=0.090,P<0.01),thrombosis prevention and treatment nursing group(?=0.198,P < 0.001)and nursing standard(?=0.092,P <0.01),six factors were considered;The influencing factors of nurses' attitude scores were nurse's gender(?=0.126,P<0.001),age(?=-0.092,P<0.05),education level(?=0.114,P<0.001),nurse level(?=-0.122,P<0.001),hospital level(?=0.155,P<0.001),bed utilization rate(?=-0.085,P<0.01),head nurses' professional title(?=0.398,P<0.001)and whether there were thrombosis prevention and treatment nursing group(?=0.215,P<0.001),eight factors were considered;Nurses' gender(?=0.087,P<0.01),nurses' level(?=-0.276,P<0.001),hospital level(?=0.214,P<0.001),bed utilization rate(?=0.069,P<0.05),the title of head nurse(?=0.245,P<0.001)and whether there are nursing standards for prevention and treatment of venous thrombosis(?=0.066,P<0.05)are six factors influencing the score of DVT prevention practice of nurses in perioperative period.(3)The correlation coefficient analysis showed that knowledge,attitude and practice were positively correlated,r=0.087?0.080 and 0.422,respectively,P<0.05,variances are with statistical significance.ConclusionThe self-compiled questionnaire,The Questionnaire of Nurses' Knowledge,Attitude and Practice on Preventing Deep Venous Thrombosis in Perioperative Period,has been validated with study results and can be used as an investigation tool for nurses' prevention of deep venous thrombosis.The knowledge and pratice of nurses in Qingdao to prevent deep venous thrombosis during perioperative period were low,and need to be further improved.Surgical nurses have good attitude and positive attitude in preventing deep venous thrombosis.The level of attitude of nurses in operating room in preventing deep venous thrombosis was lower than that of surgical nurses.The theory of knowledge,attitude and Practice can be referenced to try to construct the training system of perioperative specialized nursing,and carry out in-depth study on the whole course and continuous nursing process of perioperative prevention of deep venous thrombosis. |
