VITAL demonstrated the feasibility of harmonizing, visualizing, and evaluating wearable health data for clinical use, with findings suggesting the tool is practical and valuable for supporting clinical workflows.
VITAL successfully integrated wearable health data from four major consumer device brands into a standardized format.
Data quality in VITAL was operationalized using three quantifiable metrics: completeness, recency, and plausibility.
All seven clinician participants successfully completed assigned tasks during usability testing with minimal errors.
UTAUT survey results indicated favorable user acceptance of VITAL among clinician participants.
Clinician interviews identified both strengths and areas for improvement in the VITAL prototype.
The development process for VITAL followed a structured three-phase approach.
This research describes the development and early testing of a software tool called VITAL (Validation and Inspection Tool for Armband-based Lifelog data), designed to help clinicians make practical use of health data collected from consumer wearable devices like Apple Watches, Fitbits, Samsung wearables, and Xiaomi bands. A key challenge in clinical settings is that wearable devices produce large amounts of data in different formats, and there are concerns about data quality and the difficulty of reviewing it efficiently. VITAL addresses this by pulling data from multiple devices into a single standardized format, visualizing it interactively, and automatically assessing data quality based on whether the data is complete, recent, and plausible. To test whether the tool was usable, seven clinicians were asked to perform specific tasks using the prototype and then complete a standardized survey about their experience. All seven successfully completed the tasks with minimal errors, and their survey responses reflected positive attitudes toward the tool's usefulness, ease of use, and likelihood of adoption. Clinicians appreciated the visualization features but also suggested simplifying the interface and adding data types like heart rhythm (ECG) and dietary information. This research suggests that it is feasible to bring together wearable health data from different consumer devices into a single, clinician-friendly tool that also monitors data quality. The positive early usability results indicate the concept is practical and worth pursuing further, though the authors note that larger studies in real clinical environments will be needed to confirm whether VITAL effectively supports clinical decision-making in practice.
