A Study of Factors Influencing Willingness to Use Clinical Decision Support Systems
Objective To study clinicians'willingness to use clinical decision support system and its influencing factors,and to provide reference for the management optimization of the system.Methods A model was constructed and research hypotheses were formulated based on task-technology fit theory and technology acceptance theory,and a questionnaire survey was conducted on 247 clinicians.The data were analyzed using partial least squares structural equation modeling.Results The extent to which the factors in the model explained physicians'willingness to use was 65.8%.Task characteristics(β=0.168,P<0.01)and technical characteristics(β=0.749,P<0.01)positively influenced task-technology match,task-technology match positively influenced perceived ease of use(β=0.692,P<0.01)with performance expectations(β=0.508,P<0.01),perceived ease of use(β=0.108,P=0.073)had no statistically significant effect on the willingness to use was not statistically significant,performance expectations(β=0.228,P<0.01)positively influenced their willingness to use,task technical match(β=-0.281,P<0.01)and perceived ease of use(β=-0.377,P<0.01)negatively influenced perceived risk,and perceived risk negatively influenced physicians'performance expectations(β=-0.308,P<0.01)and willingness to use(β=-0.579,P<0.01).Conclusion Improving and optimizing system functions and improving the adaptability of system features to users'business can improve doctors'performance level,reduce users'perceived risk,and increase doctors'willingness to use clinical decision support systems.
