Use and Acceptability of an AI-Assisted Health Application for Individuals Living With a Chronic Condition (SOFIA)
SOFIA: Evaluation of the Use and Acceptability of an AI-Assisted Health Application for Individuals Living With a Chronic Condition
The SOFIA study evaluates a web-based health application for people living with one or more chronic conditions. The study aims to find out whether the SOFIA application is useful, easy to use, and used over time by participants.
The SOFIA application offers tools to support the day-to-day management of health: lifestyle challenges, health data entry and personal tracking (e.g., blood pressure, weight), medication tracking for people using pochettes-doses (pharmacy-prepared unit-dose packets), and an AI conversational assistant providing general health information. The application does not make diagnoses, give personalized medical advice, or recommend treatment. It complements usual medical care but does not replace it.
The study first enrolls people with hypertension, then, subject to ethics committee approval, people with type 2 diabetes and obesity.
Participation takes place entirely online, through the SOFIA application, accessible from a web browser (smartphone, tablet, or computer). There are no in-person visits. Participants use the application freely, at their own pace, until the end of the study. Short questionnaires (most take 1 to 3 minutes) are offered in the application during the study, and a final questionnaire (about 20 minutes) at the end.

Szczegółowy opis
Regulatory classification: Other Clinical Trial according to the Swiss Ordinance on Clinical Trials (ClinO, Chapter 4), Risk Category A.
Deployment model: All application users are study participants; the digital informed consent also serves as the terms of use. Enrolment is rolling from application launch and opens by condition as its content is integrated, starting with hypertension.
Data collection: Usage data (sessions, feature use, AI interactions, scan events) are collected server-side. Validated instruments are delivered individually within the application on a rotating micro-assessment schedule, with a final assessment administering all instruments simultaneously.
Safety: Adverse events can be reported at any time within the application. An urgency classifier triggers the display of emergency numbers (144 / 143) when needed.
Statistical analysis: Acceptability is tested formally (one-sided α = 0.025, mixed-effects model). Retention is evaluated descriptively, with Kaplan-Meier analysis as supportive analysis. Secondary endpoints are analyzed with mixed-effects models or generalized estimating equations. Sensitivity analyses include multiple imputation, a per-protocol set, and tipping-point analyses. Sex-disaggregated analyses are planned across all endpoints.
Data protection: Data are coded, hosted in Switzerland, and encrypted (AES-256 GCM).

Eksperymentalny: SOFIA application
Participants with a self-reported diagnosis of hypertension using the SOFIA application. |
AI-assisted health application accessible on any device with a web browser (smartphone, tablet, or computer), comprising: (1) gamified lifestyle challenges; (2) health data entry and personal tracking; (3) medication tracking via pochettes-doses data matrix scanning; (4) an AI conversational assistant providing general, evidence-based health information. A complement to, not a replacement for, usual medical care. |
