Abstract
Background: COVID-19 pandemic has affected mankind globally. After the two waves since March 2020, an impending third wave is anticipated soon. Vital parameter monitoring through remote health monitoring system (RHMS) becomes critical for effectivedisease management and manpower safety. In a low resource setting as India, a comprehensive, wearable and remotely operable device that is economical is required to be introduced for COVID care.
Objectives: Present study validates the Remote Health Monitoring device named COVIDBEEP with a standard ICU monitor.
Methods: Six parameters, heart rate, SpO2, respiratory rate, digital temperature,blood pressure and ECG were acquired in the supine positionusing both the devices.
Results: Analysis was performed using GraphPad Prism. Intra class correlation coefficients were used to measure concurrent validity. Bland-Altman graphs were plotted to know the agreement for each vital parameter. Confidence limits were set at 95%.
Results: All the parameters recorded from both the devices showed a significant correlation with an ‘r’ value between 0.5 – 0.9 with p value between 0.001 - 0.0002. Bland-Altman plots showed a minimum bias of 0.033 for heart rate and maximum of 3.5 for systolic blood pressure and respiratory rate.
Interpretation and Conclusion: The association between the parameters recorded by both the devices strengthened as the time of collection of data increased. Agreement between the two methods in 95% confidence interval was also proven to be significant for the parameters. Therefore, the indigenously developed COVIDBEEP has shown good validity in comparable to standard monitoring device.
