Study summary

This is a single-arm prospective study, investigating the feasibility, usability, and safety of a wearable bioimpedance sensor in elderly individuals. The sensor is applied on the upper back of the subject, and will be replaced once weekly. The study will include four phases, each interspersed by an interim analysis. Each phase will have a duration of four weeks.

Interventions

  • DeviceWearable bioimpedance sensor

    The investigational device is an electronic bioimpedance-based, body-worn, battery-powered sensor intended to monitor changes in fluid balance. It is designed as an adhesive patch with four integrated electrodes. The outer electrodes are used to supply a low current, while the inner electrodes are used for voltage measurements.

What researchers measure

Primary outcomes

  1. Mean use time of the wearable sensor

    Time frame: Up to 7 days

Secondary outcomes

  1. The mean number of days the sensor provides valid measurements

    Time frame: Up to 7 days

  2. Mean and standard deviation of the device output variables

    Time frame: Up to 7 days

  3. Stability of device measurements following weekly patch replacement

    Test-retest reliability of the investigational device will be investigated by assessing the correlation between impedance measurements (in Ohm) before and after device replacement.

    Time frame: Day 8, 15, 22, 29

  4. Clinical assessment of hydration status

    Time frame: Day 1, 8, 15, 22, 29

  5. User satisfaction

    Will be assessed using a likert scale from 1-5, where 1 represents "strongly disagree" and 5 represents "strongly agree".

    Time frame: Day 8, 15, 22, 29

  6. Frequency and severity of adverse device effects

    Time frame: Day 1-30
