Current guidelines recommend that self monitoring of blood pressure at home should only be performed using validated devices. This study assessed the accuracy of the Microlife WatchBP Home device for self home blood pressure measurement according to the European Society of Hypertension International Protocol.
Thirty-three participants were included (15 in phase 1 and an additional 18 in phase 2). Simultaneous blood pressure measurements were taken by two observers (Y-tube-connected mercury sphygmomanometers) four times sequentially, with three measurements taken using the tested device. Absolute differences between observer and device measurements were classified into three zones (within 5, 10 and 15 mmHg). The number of measurements with a difference within 5 mmHg was calculated for each individual.
In phase 1, the device produced 38, 43 and 43 measurements within 5, 10 and 15 mmHg, respectively, for systolic blood pressure and 35, 45 and 45 for diastolic blood pressure. In phase 2.1, the device produced 75, 91 and 97 measurements within 5, 10 and 15 mmHg for systolic, and 74, 93 and 99 for diastolic blood pressure. In phase 2.2, 30 participants had at least two of their differences within 5 mmHg and two participants had no differences within 5 mmHg for systolic blood pressure, whereas for diastolic blood pressure the number of participants were 27 and three, respectively. Mean difference for systolic blood pressure was -0.3+/-5.6 mmHg and for diastolic -2.4+/-4.8 mmHg.
The Microlife WatchBP Home device for self home blood pressure measurement fulfills all the validation criteria of the International Protocol and can, therefore, be recommended for clinical use in the adult population.
当前指南建议，家庭自测血压应仅使用经过验证的设备进行。本研究根据欧洲高血压学会国际协议评估了Microlife WatchBP Home设备用于家庭自测血压的准确性。
纳入33名参与者（第1阶段15名，第2阶段额外18名）。两名观察者（使用Y形管连接的汞柱式血压计）依次进行4次同步血压测量，同时使用测试设备进行3次测量。将观察者与设备测量值之间的绝对差值分为三个区域（5 mmHg以内、10 mmHg以内和15 mmHg以内）。计算每个个体差值在5 mmHg以内的测量次数。
在第1阶段，该设备收缩压在5 mmHg以内、10 mmHg以内和15 mmHg以内的测量次数分别为38次、43次和43次，舒张压分别为35次、45次和45次。在第2.1阶段，该设备收缩压在5 mmHg以内
