Study Details

Study Description

Brief Summary

In this pilot study the feasibility of continous monitoring of health data with a small, on-skin wearable device (the Everion®, by Biovotion, Zurich) in pediatric patients under chemotherapy for cancer, is studied. Feasibility is assessed by the number of patients wearing the device on seven consecutive days for at least 18h/day, what will be measured by monitored heart rate. Study duration for each participant is 14 days.

Condition or Disease Intervention/Treatment Phase
  • Device: Everion

Detailed Description

No study has proved feasibility of continuous monitoring of health data with a small wearable device such as the device Everion® in pediatric patients. It is not known if children tolerate the device and if data quality sustains with smaller arm circumferences or when worn on the upper leg. Neither is it known if parents and/or patients can and are willing to handle the device in ambulant setting. Therefore, this pilot study assesses the feasibility of continous monitoring of health data with a small, on-skin wearable device (the Everion®, by Biovotion, Zurich) in pediatric patients under chemotherapy for cancer.

Arms and Interventions

Arm Intervention/Treatment
Everion®

The Everion® will be given to the participants for the duration of 2 weeks (fourteen days) with the instruction to wear it all the time, with exception of the time needed for battery charging and the patients' hygiene.

Device: Everion
The Everion® device, by Biovotion, Zurich, is a on-skin wearable device measuring health data.

Outcome Measure Data

Analysis Population Description
The analysis of differences between discrete measurements and continuously recorded aggregates of vital signs, as defined in the protocol, was found to yield massively distorted results because rapidly changing discretely measured vital signs were compared to aggregated means covering up to 20 min. We deliberately refrain from displaying these nonmeaningful results here.

Limitations/Caveats

(i) The WDs were studied for only 14 days and compliance might be different during long-term use. (ii) The small number of patients precluded an analysis of patient factors (iii) The planned comparison of discrete measurements versus continuously was not feasible because the exact second-wise time point of discrete measurements was not available.
