NCT05418881

Brief Summary

The study investigates the technical feasibility of using mobile health trackers for monitoring of hospitalized patients. Therefore the measurement accuracy of several vital parameters in postoperative hospitalized patients will be compared to clinical gold standard. Factors that could have an influence on the measurement accuracy of the mobile sensors will be investigated.Furthermore patient compliance in continous use of mobile health trackers and technical feasibility of needed data flow will be analyzed. In addition, patients' activity levels are recorded and correlated with various clinical parameters.

Study Arms (2)

postoperative Spot Measurements

OTHER

Measurement of vital signs via 4 different tracking devices in the setting of post-anaesthesia care unit. Simultaneous collection of vital signs measured by the gold standard of clinical monitoring (ecg, blood-gas-analysis, invasive blood pressure, transmissive photoplethysmography).

Device: Mobile Tracking Device (one spot)

Longitudinal postoperative Measurements

OTHER

Continuous measurement of vital signs and activity level with tracking devices for the postoperative period in the patient ward up until 21 days postoperative.

Device: Mobile Tracking Device (one spot)Device: Mobile Tracking Device + Activity Sensor (longitudinal)

Interventions

Patients will be fitted with 4 different tracking devices (Garmin Fenix 6 Pro®, Apple Watch 7®, FitBit Sense®, Withings ScanWatch®).

Longitudinal postoperative Measurementspostoperative Spot Measurements

Patients will be fitted with 1 of 3 different tracking devices (Garmin Fenix 6 Pro®, Apple Watch 7®, Withings ScanWatch®). The type of tracking device will be randomized. Additionally an Activity Tracker and one-channel ECG (Movesense®) will be worn by the patients.

Longitudinal postoperative Measurements
