Medical professionals' adoption of AI-based medical devices : UTAUT model with trust mediation

The purpose of this study is to identify the factors impacting medical professionals' adoption intention of AI-based innovative medical devices focused on the mediating role of trust. Drawing on the UTAUT model, we examined the mediating effect of trust in the relationships between these factors (performance expectancy, effort expectancy, facilitating conditions, and social influence). This study collected survey data through convenient sampling from 248 medical professionals working in medical institutions located in the metropolitan areas in Republic of Korea. The result showed that performance expectancy, effort expectancy, facilitating conditions, and social influence have a positive impact on trust, and this trust, in turn, has a significant influence on acceptance intentions. The results emphasize that the success of introducing innovative medical devices in institutions hinges not only on the devices' innovation level but also on the psychological factors of the professionals. By taking into account these factors and building trust, medical institutions can elevate service quality and efficiency, fostering greater acceptance of advanced medical devices.
