Feasibility Assessment of All-in-One Portable Measurement Device for Home-Based Remote Vital Sign Monitoring

Abstract

This research presents an all-in-one portable vital sign (PVS) measurement device integrated with a cloud platform for remote patient monitoring in a home isolation setting. The study aims to evaluate the device's usability by comparing its vital sign measurements with clinical vital sign simulators and conducting trials with mild symptom COVID-19 patients. The PVS device successfully demonstrates a high level of agreement with the clinical vital sign simulators, signifying its reliability in providing accurate data based on Pearson’s correlation coefficient. Furthermore, when assessed by mild symptom COVID-19 patients, the device exhibits 95% confidence interval agreement with standard home use vital sign devices in measuring blood pressure, pulse rate, SpO2, and temperature using the Bland–Altman method. The findings suggest that the conceptual PVS device may be used in diverse healthcare settings, including elderly community healthcare and acute respiratory infection (ARI) units. Future work will involve integrating edge computing to enhance connectivity reliability and reduce data transmission delays, further improving the system’s efficiency. Overall, this innovative research lays the groundwork for broader applications of the PVS cloud-based system, contributing to advancements in remote patient monitoring and effective healthcare resource management in challenging healthcare scenarios.
