BACKGROUND: Self-measured blood pressure (SMBP) monitoring is increasingly used for remote hypertension management, but the real-world performance of home blood pressure (BP) devices is unknown. We examined BP measurements from patients' home devices using the American Medical Association's (AMA) SMBP Device Accuracy Test tool.
METHODS: Patients at a single internal medicine clinic underwent up to five seated, same-arm BP readings using a home device and an automated BP device (Omron HEM-907XL). Following the AMA's three-step protocol, we used the patient's home device for the first, second, and fourth measurements and the office device for the third and fifth (if needed) measurements. Device agreement failure was defined as an absolute difference in systolic BP >10 mm Hg between the home and office devices in either of two confirmatory steps. Performance was examined by brand (Omron vs. non-Omron). Moreover, we examined patient factors associated with agreement failure via logistic regression models adjusted for demographic characteristics.
RESULTS: We evaluated 152 patients (mean age 60 ± 15 years, 58% women, 31% Black) seen between October 2020 and November 2021. Device agreement failure occurred in 22.4% (95% CI: 16.4%, 29.7%) of devices tested, including 19.1% among Omron devices and 27.6% among non-Omron devices (P = 0.23). No patient characteristics were associated with agreement failure.
CONCLUSIONS: Over one-fifth of home devices did not agree based on the AMA SMBP device accuracy protocol. These findings confirm the importance of office-based device comparisons to ensure the accuracy of home BP monitoring.
