" Why is the Doctor a Man" Reactions of Older Adults to a Virtual Training Doctor

Shared decision making (SDM) is increasingly considered as the best way to reach a treatment decision in a clinical environment. However, the use of SDM in practice can be obstructed by a number of factors, such as time constraints or lack of applicability due to patient characteristics. Our project, PrepDoc, explores how a Virtual Training Doctor (VTD) can help patients overcome some of these obstacles to experiencing effective SDM during doctor's visits. In this paper, we report on user studies conducted with 19 participants in Scotland aged 65+. The goal of these studies was to identify the reactions of this audience to the PrepDoc system, evaluate its suitability within Scotland, and elicit suggestions to improve it. Our findings revealed that the idea of empowering people to participate in SDM using a virtual agent was positively received by all participants. However, the reactions to how this idea was implemented in the PrepDoc system varied greatly across participants. Based on this, our paper outlines recommendations for enhancing the user experience with VTDs, accommodating individual differences of older adults, and accounting for the national context.
