Survey of tumor marker prescription behavior in lung diseases based on IMB model / 上海交通大学学报（医学版）

ABSTRACT

Objective·To explore the influencing factors and pathways of clinicians' tumor marker prescription behavior in lung diseases,so as to find out the methods and measures to promote clinicians to optimize the tumor marker prescription.Methods · From July 24,2017 to August 10,2017,clinicians with willingness and the right of prescription mainly from hospitals in Shanghai and Beijing were invited to participate in survey on influencing factors of tumor marker prescription behavior in lung diseases.Based on the classical theoretical framework of IMB model,an IMB theoretical model of clinicians' tumor marker detection behavior was proposed.Statistical description and correlation analysis were performed by SPSS 24.0,and the IMB theoretical model was validated and corrected by AMOS 24.0.Results· The personal intention (r=0.251,P=0.000) and personal interest protection (r=0.178,P=0.007) had a significant positive correlation with information.Meanwhile,the personal intention (P=0.000) and personal interest protection (P=0.013) had a significant positive effect on behavioral skills,and the behavioral skills had a significant positive effect on tumor marker prescription behavior (P=0.000).There was no direct effect of information on behavioral skills,and motivation had no direct effect on tumor marker prescription behavior.Behavioral skills played a mediating role in the process of motivation influencing the tumor marker prescription behavior.Conclusion· The large percentage of irrational tumor marker prescription in lung diseases suggests the universality of inappropriate testing,which needs the joint efforts of governments,hospitals,clinicians and patients on improvement.
