基于结构方程模型的中国医院药物警戒系统使用意愿研究

A study of willingness to use Chinese Hospital Pharmacovigilance System based on structural equation modeling

目的:整合2个信息技术研究模型(TAM与TTF)作为中国医院药物警戒系统(Chinese hospital pharmacovigilance system,CHPS)使用意愿研究视角,以了解哪种因素会影响医务人员对CHPS的接受度,为提升用户使用意愿相关问题提供理论基础。方法:本研究采用网络调查方式发放并回收问卷,选择CHPS全国线上培训交流群中使用过CHPS的医务人员作为目标群体,对收集到的样本数据进行描述性统计分析、PLS-SEM建模与分析,其中PLS-SEM分析是对测量模型和结构模型进行研究,数据处理软件采用SmartPLS 3。结果:应答者多为药师,占93%;提出的测量模型具有良好的信效度;模型中所有的路径在5%的显著性水平上具有统计学意义,本研究假设皆成立;R2=0.721,说明整合模型对医务人员的CHPS使用意愿解释力为72%。结论:TAM-TTF整合模型能较好地解释CHPS使用意愿情况,医院管理层和系统开发者应加强培训、提升医务人员的使用体验,应持续关注医务人员的工作需求和使用CHPS时遇到的问题。该研究能够帮助了解中国医院在推广实施CHPS时遇到的障碍,以更好的规划CHPS的实施。

OBJECTIVE To integrate two information technology research models(TAM and TTF)as a research perspective on Chinese Hospital Pharmacovigilance System(CHPS)usage intention in order to understand the factors affecting medical personnel's acceptance of CHPS and to provide a theoretical basis for the issues related to improving users’willingness to use it.METHODS This study used a web-based survey to distribute and collect questionnaires,selected medical personnel who had used CHPS in the CHPS national online training communication group as the target group,and conducted descriptive statistical analysis,PLS-SEM modeling and analysis on the collected sample data,where PLS-SEM analysis was conducted on the measurement model and structural model,and the data processing software was SmartPLS3.RESULTS The respondents were mostly pharmacists,accounting for 93%;the proposed measurement model had good reliability and validity;all the paths in the model were statistically significant at the 5%level of significance,and all hypotheses of this study were valid;R2=0.721,indicating that the explanatory power of the integrated model for medical personnel's intention to use CHPS was 72%.CONCLUSION The TAM-TTF integrated model can better explain the willingness to use CHPS,and hospital management and system developers should strengthen training and improve medical staff’s experience,and should continuously pay attention to medical staff's work needs and problems encountered during CHPS use.This study can help to understand the barriers encountered by Chinese hospitals in promoting the implementation of CHPS in order to better plan its implementation.
