Shared decision making: using theories and technology to engage the patient in their health journey

Shared decision making is considered the cornerstone of patient-centred care but transpires in only 10% of face-to-face consultative encounters. Technology interventions have rampantly sought to fill the shared decision making gap but fall short in patient engagement. Recent studies indicate that combining multiple approaches could lead to greater commitment towards achieving positive health outcomes. Consequently, this study combines and embeds the I-Change behavioural theory with choice architecture within a technology-based aid to facilitate shared health decision making for hypertension reduction. An ontology knowledge model combining the behavioural and choice methods forms the core framework that will inform the technical solution. The model is both scalable and patient-centric. A pilot study will trial the solution, solicit feedback and propose refinements for future clinical use.
