MAPLE2 Mobile Application

Automating GA and communication support through the mobile application is intended to eliminate the workforce and time barriers that have constrained GA adoption in routine oncology practice. Completing the app-based intervention takes an estimated 30–40 minutes, with an additional 10–20 minutes for baseline GA and questionnaires. The application was built from MAPLE trial data: recorded patient-provider conversations were categorised by GA domain and analysed with text mining to extract frequently selected QPL items and common patient expressions. The app embeds domain-specific best-practice scenarios built algorithmically from MAPLE data, enabling tailored guidance without face-to-face facilitation by trained providers. The MAPLE2 mobile application enables older adults to complete geriatric assessment independently, auto-generates guideline-concordant management recommendations, and produces a personalised question prompt list linked to individual GA results. Research staff provide step-by-step guidance and real-time technical support for participants who have limited digital literacy.
