Abstract：
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.
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.
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.
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.

摘要：
背景：自测血压（SMBP）监测越来越多地用于远程高血压管理，但是家用血压（BP）设备的实际性能尚不清楚。我们使用美国医学协会（AMA）的自我测量血压（SMBP）设备准确性测试工具检查了患者家用设备的BP测量值。
方法：单个内科诊所的患者接受了多达5个座位，使用家用设备和自动BP设备（OmronHEM-907XL）的同臂BP读数。按照AMA的3步协议，我们第一次使用了病人的家用设备，第二,和第四次测量以及用于第三次和第五次(如果需要)测量的办公设备。设备协议失败定义为在两个确认步骤中的任一步骤中，家用和办公室设备之间收缩压>10mmHg的绝对差异。业绩按品牌进行了检查(欧姆龙vs非欧姆龙)。此外，我们通过对人口统计特征进行校正的logistic回归模型研究了与协议失败相关的患者因素.
结果：我们评估了152名患者（平均年龄60±15岁，58%的女性，31%黑色）在2020年10月至2021年11月之间。设备协议失败发生在22.4%(95%CI：16.4%，29.7%)的测试设备，其中欧姆龙设备占19.1%，非欧姆龙设备占27.6%(P=0.23)。没有患者特征与协议失败相关。
结论：根据AMASMBP设备准确性协议，超过五分之一的家庭设备不一致。这些发现证实了基于办公室的设备比较的重要性，以确保家庭BP监测的准确性。
