Postoperative Remote Monitoring with a Transcutaneous Biosensing Patch: Preliminary Evaluation of Data Collection.

Abstract

Introduction. Connected systems transmitting vital parameters could well represent a tool to shorten postoperative hospital stay while providing continuous remote patient monitoring and potentially detect the onset of complications. Our aim was to analyze the functionality of a transcutaneous biosensing data collection patch in morbidly obese patients. Materials and Methods. An adhesive patch (The HealthPatch MD™) was applied to patients' chests postoperatively. The patch was connected to a tablet via a bluetooth network to collect the heart rate, respiratory rate, skin temperature, and posture recognition data. The tablet conveyed data to a secure health data central server by means of a WiFi or 3G/4G transmission. Data were stored in a digital health platform to which health care professionals could connect. The evaluation focused on the volume, quality, and security of data transmission. A pilot phase involved 10 patients. Thirty-three additional patients undergoing bariatric surgery were included in the experimental phase. Results. The mean length of stay was 2.28days (range: 2-5days). The mean time of patch application was 51 ± 25.2hours per patient (range: 19-139hours), totalizing 1,683hours of recording for the 33 patients included. During this time, a total of 7.562.531 data measurement points were collected and transmitted to the e-health platform via the patch. Two total disconnections and two partial disconnections were observed. The acquisition of patient postural data was unreliable. Conclusions. Connected telemetry for remote postoperative monitoring is promising. However, it is still limited by data transmission problems.
