Development And Application Of The Occupational Protective Behavior Scale Of Hepatitis B Virus In Medical Workers

Objectives: The purpose of this study was to develop the occupational protection behavior scale of hepatitis b virus for health care workers,and to test the validity and stability of the scale for reliability and validity,so as to provide an evaluation tool for the current investigation of occupational protection of hepatitis b virus for health care workers.This paper investigates the status of occupational protection against hepatitis b virus among medical staff in a city general hospital,probes into the influencing factors,and puts forward reasonable Suggestions according to the specific situation,providing reference for the intervention measures of occupational protection against hepatitis b virus among medical staff.Methods: 1.Development of occupational protective behavior scale of hepatitis b virus for medical workers.(1)Create an entry pool On the basis of literature research,combined with semi-structured interview results,relevant data were analyzed and sorted out.After discussion by the research group,the item pool was preliminarily determined.(2)Delphi method According to the inclusion criteria,17 experts in related fields were selected.two rounds of expert consultation were conducted on the initially established item pool using Delphi method.The dimensions and items of the questionnaire were screened and modified by using the degree of expert positivity,the degree of expert authority and the degree of expert opinion coordination to form the predictive test questionnaire.(3)Pretest A total of 138 medical staff in a grade a general hospital were tested.Items were screened by correlation coefficient analysis method,discriminant analysis method and Cronbach's ? coefficient analysis method to form a questionnaire for formal test.(4)Formal testing A total of 138 medical staff in a grade a general hospital were tested.Items were screened by correlation coefficient analysis method,discriminant analysis method and Cronbach's ? coefficient analysis method to form a questionnaire for formal test.2.Investigation and study on occupational protection status and influencing factors of hepatitis b virus among medical workers.A total of 637 medical staff from 1 grade-ii general hospital and 2 grade-iii general hospital in a city were investigated by using the self-designed general information questionnaire and the medical staff's hepatitis b virus occupational protection behavior scale.(1)The mean standard deviation percentage was used to describe the general information of medical staff and the score of questionnaire dimensions and items.(2)T-test,one-way analysis of variance,Multivariate linear regression analysis were used to explore the influencing factors of occupational protection against hepatitis b virus in medical workers.Results: 1.The development of occupational protective behavior scale of hepatitis b virus in medical workers.(1)Through literature research and semi-structured interview,a total of 49 articles on occupational protection against hepatitis b virus among medical staff were collected,which were analyzed and sorted by members of the research group,and finally summarized into a pool of 33 articles.(2)Through two rounds of expert consultation,the expert positive coefficient is 1.0,the expert authority coefficient is 0.912,and the expert opinion coordination coefficient is 0.378 and 0.453,respectively.According to the expert opinions and combined with the clinical situation and discussion of the research group,a total of 1 dimension and 11 items were removed,1 item was retained,1 item was added and 8 items were modified.(3)After the predictive test,items 4,5 and 7 were deleted by predictive test according to the screening criteria of correlation coefficient analysis method and differentiation degree analysis method and Cronbach's ? coefficient analysis method.(4)After the formal test,the Cronbach's ? coefficient of the total scale was 0.841,and the Cronbach's ? coefficient of each dimension was 0.742,0.719,0.775,0.795 and 0.708.The spearman-brown coefficient of the total scale was 0.805,and the spearman-brown coefficient of each dimension was 0.708?0.701?0.772?0.758?0.718.The content validity index of the total scale was 0.930,and the content validity index of each item was 0.800~1.000.Exploratory factor analysis results in 5 common factors,cumulative variance contribution rate 68.25%,the factor loading quantity of each item is 0.462~0.919.The correlation coefficient between dimensions is 0.188~0.411,the correlation coefficient between each dimension and the total scale is 0.373~0.739.The occupational protective behavior scale of hepatitis b virus in medical workers was finally formed.2.Investigation and study on occupational protection status and influencing factors of hepatitis b virus among medical workers.(1)The total score of occupational protection against hepatitis b virus for medical staff in 1 grade-ii general hospital and 2 grade-iii general hospital was 82.76±8.58 points,with scores ranging from 20 to 100 points.The score of standard prevention dimension was 11.05±1.99 points,and the score ranged from 3 to 15 points.The score of sharp instrument injury prevention was 21.43±2.73 points,and the score ranged from 5 to 25 points.The score of sharp box use dimension was 13.57±1.62 points,and the score ranged from 3 to 15 points.The score of emergency handling dimension was 20.91± 2.93 points,and the score ranged from 5 to 25 points.The score of immunoprophylaxis dimension was 15.80±3.22 points,and the score range was 4 to 20 points.The scores of each dimension were from high to low in order of use sharp box,emergency processing,sharp instrument injury prevention,immunoprophylaxis,the standard prevention.(2)To the different characteristics of medical staff and the scores of occupational protection for independent sample t-test and single factor analysis of variance,the results show that the fixed number of year of the degree title work in hospital department level influence medical staff the hepatitis b virus scores of occupational protection by the multiple linear regression analysis found that working fixed number of year and hospital level is the medical staff occupational protection of main factors influencing the hepatitis b virus analysis results were statistically significant(P<0.05).Conclusion: 1.The occupational protective behavior scale of hepatitis b virus in medical workers including 5 dimensions and 20 items,the scale has good reliability and validity,and can be used as an assessment tool to measure occupational protection against hepatitis b virus among medical staff,but it still needs to be further verified and improved in clinical practice.2.Investigation and analysis of medical staff occupational protection the overall level of hepatitis b virus is good,the fixed number of year of the degree title work in department level is the hospital medical staff the influence factors of hepatitis b virus occupational protection,therefore,implement the safety education and training of occupational protection for medical staff,medical staff should be considered the influence factors of occupational protection,from the perspective of scientific pertinence,improve the level of medical staff occupational protection,the protection behavior in the daily work,reduce the incidence of occupational exposure.
