Key result
Everlast and BodiMetrics cuffless devices fail to accurately measure BP compared to standard reference monitors.
Why the study?
Cuff-less handheld devices and smartwatches may aid frequent BP monitoring, but the accuracy and precision of popular devices required investigation.
Does cuff-less blood pressure measurement using the Everlast smartwatch or BodiMetrics Performance Monitor provide accurate readings compared to a hospital-grade automated sphygmomanometer?

Does cuff-less blood pressure measurement using the Everlast smartwatch or BodiMetrics Performance Monitor provide accurate readings compared to a hospital-grade automated sphygmomanometer?
Effect estimate: MD 16.9 mm Hg (Everlast SBP), MD 8.3 mm Hg (Everlast DBP), MD 5.3 mm Hg (BodiMetrics SBP)
The tested cuff-less smartwatch and portable health devices demonstrated significant deviations from standard sphygmomanometer readings, indicating they are not currently accurate enough for clinical blood pressure monitoring.
Helmond et al. (2019) reported a cross-sectional. Everlast smartwatch and BodiMetrics Performance Monitor vs. Hospital-grade automated sphygmomanometer was evaluated on Mean absolute difference between investigational devices and reference for SBP and DBP (MD 16.9 mm Hg (Everlast SBP), MD 8.3 mm Hg (Everlast DBP), MD 5.3 mm Hg (BodiMetrics SBP)). The Everlast smartwatch and BodiMetrics Performance Monitor were not accurate enough for BP measurement, with average systolic differences of 16.9 mm Hg and 5.3 mm Hg compared to a reference device.
