Transitional Care Study 3

Philips Electronics Nederland B.V. acting through Philips CTO organization350 enrolled

Overview

In this study patients with elective surgery will wear two devices (HealthDot and Elan) after surgery in hospital and after discharge at home for up to 2 weeks (HealthDot) or 3 weeks (Elan). The HealthDot will measure heart rate, posture, activity and respiratory rate which are stored on the device as well as sent to Philips. The Elan device will measure PPG and accelerometer data which is transferred to Philips. The data collected will be used for algorithm development. Data will be analysed retrospectively and compared to readmission and adverse events to see if the events could have been predicted due to the collected data by the devices. No clinical decisions will be based on the measurements done during the study.

Outcomes

Primary Outcomes

Sensitivity and specificity

Evaluate the sensitivity and specificity for the prediction of deterioration after surgery using the data from both devices.

Time frame: 3 weeks

Secondary Outcomes

Accuracy HealthDot

Evaluate if the calculated heart rate and respiratory rate data collected by HealthDot are accurate compared to a gold standard as used in the hospital

Time frame: 2 weeks

Comfort of wearing measured by questionnaire

Comfort of wearing the HealthDot will be assessed by VAS scale 1-10 while 1 beeing very comfortable, and 10 very uncomfortable

Time frame: at week 2

Accuracy Elan

Evaluate if the calculated heart rate and respiratory rate data collected by Elan are accurate compared to a gold standard as used in the hospital
