Today, studying continuous clinical decision support system (CDSS) use is critical as continuity is a prerequisite to sustaining successful CDSS implementations. Previous health information technology (HIT) research has focused on HIT acceptance via information system-related constructs. Theoretical models explaining HIT use are limited and obfuscated other phases of HIT, such as continuous use in a clinical context. This study seeks to fill this gap by integrating context-related factors with IS factors in a theoretical framework that explains the antecedents of continuous use. To validate this model, data were collected from physicians after six months of using CDSS as well as system usage data from system logs. Threats to physician professional identity surpassed the intention to continue using CDSS, influencing its use by physicians in the first six months, and patients affected by the system influenced physician satisfaction with the system and, hence, their use of the system. This study reveals physicians' continuous use of CDSS and explains the effects of healthcare contexts on physicians' behaviour. [ABSTRACT FROM AUTHOR]

Healthcare is an area that has benefitted from the developments in wearable device technology. Seniors, who usually suffer from multiple comorbidities, are among the target users of these devices, and research has shown potential health benefits for seniors when they use these devices effectively. However, the adoption rate of wearable devices is low, especially among seniors, preventing the full utilisation of their data in healthcare. In this study, we interviewed forty-four seniors across North America and collected data from their wearable devices to develop a theoretical affordance network-based model to explain seniors' effective use of wearable devices. Our model indicates that despite the apparent simplicity of wearable devices, they have multiple affordances that help seniors achieve several goals, including activity monitoring, activity planning, and activity improvement. Furthermore, we identified factors that enable seniors to actualise the affordances of wearable devices and achieve their goals. The results of this study suggest a strong relationship between seniors' mental and physical capabilities and their willingness to use and benefit from wearable devices. We join other researchers in their call for a contextual study on consumer technology use. [ABSTRACT FROM AUTHOR]
