Intervention type: BEHAVIORAL
Intervention: CHDR Monitoring Remotely (MORE)
Description: CHDR MORE is a highly customizable platform which allows remote monitoring of patients and trial subjects, data ingestion, and data management. The current infrastructure includes an Android app to unobtrusively collect data from smartphone sensors, and a connection to the Withings Health online platform to collect wearable data. Data is stored on a secure server in a structured data scheme ensuring clear data management processes, forming a prerequisite for comprehensive data analysis. The Android app enables data collection from multiple smartphone sensors (e.g. location data, accelerometer and ambient light) as well as phone usage logs (e.g. app usage, calls and texts).

Intervention: Withings Steel HR
Description: The Withings Steel HR is a commercially available smartwatch that combines various sensors to measure activity (steps, sleep, etc.) and heart rate (HR). HR is measured using a PPG (photoplethysmogram, i.e. optically obtained volumetric measurement) based on a commercially available sensor (AS7000) incorporating low-noise and high-sensitivity analogue circuitry. The manufacturer supplies the algorithm for converting the PPG signal into HR values. Data is transferred from the watch to the smartphone using the Withings Health Mate app from where it will be uploaded to the output server.

Intervention: Withings Body+ scale
Description: Body composition (weight, BMI and Skeletal Muscle Mass) can be assessed with the Withings Body+ smart scale at home. A smart phone is required to store data and send collected data to the output server. The device does not require charging.
