Usability and feasibility of a wearable sensor-based monitoring system providing feedback on sedentary behaviour during inpatient and home-based geriatric rehabilitation

Abstract Objective This study explored the usability and feasibility of a sensor-based monitoring system that provides feedback on sedentary behaviour during inpatient and home-based geriatric rehabilitation from the perspectives of patients and healthcare professionals. Methods This mixed-methods study, which is part of the Better@Home study, included a focus group with care professionals, patient surveys, and collection of activity data (e.g. sedentary time and bout duration) via a wearable sensor monitoring system. Usability was assessed qualitatively, while feasibility was assessed using both qualitative data and quantitative adherence to the monitoring system. Focus group data were analysed using the framework method; other data were analysed descriptively. Results Twenty-six patients and nine care professionals participated. Usability was perceived as limited due to challenges on both the technology (e.g. measurement accuracy) and implementation level (e.g. tailored use and added value), which impeded integration into existing workflows. Feasibility was deemed sufficient since adherence levels were high. Conclusions From the perspectives of patients and healthcare professionals, a sensor-based monitoring system that provides feedback on sedentary behaviour showed sufficient feasibility and limited usability. To facilitate the integration into existing workflows, measurement accuracy should be improved, and implementation should focus on tailored use that offers a clear added value, in line with patient goals.
