Investigating the Antecedents of User Acceptance of Clinical Decision Support Systems: a Case from Saudi Arabia

Abstract Background The purpose of this paper is to develop an integrated research model to identify the technological and non-technological factors that influence user acceptance of the CDSS. This model is empirically tested using a data sample collected from selected healthcare facilities in Saudi Arabia. Methods The research study uses the quantitative approach to evaluate the currently implemented CDSS as a part of Hospital Information System BESTCare 2.0 in Saudi Ministry of National Guard Health Affairs. A survey questionnaire is conducted at all Ministry of National Guard Health Affairs hospitals for data collection. Then, the survey data is analyzed using Structural Equation Modeling (SEM) and AMOS 21.0. This analysis includes: measurement instrument reliability, discriminant validity, convergent validity, and hypothesis testing. Moreover, a CDSS usage data sample is extracted from the data warehouse to be analyzed as an additional data source. Results The results of the hypotheses testing show that usability, availability, and medical history accessibility are the important factors influencing user acceptance of CDSS. Conclusions This study provides prudence pertaining to healthcare facilities and their higher management to adopt CDSS.
