Therefore, recommendation of validated devices should be the first step. The present study showed that nonvalidated devices are used widely in clinical practice and a substantial portion is inaccurate. The range of inaccuracy of the validated devices was 6-26 mmHg for the systolic BP and 6-11 mmHg for the diastolic BP. Inaccuracy was more common with nonvalidated devices than validated devices.
Accuracy of the device was defined as having less than a 5 mmHg difference in the mean BP values.Ī total of 212 individuals were analyzed 38.7% (82 of 212) of the participants used validated devices and 85.4% (181 of 212) were accurate. Next, the accuracy of the individual device was evaluated by comparing the mean BP values between the automated device and a mercury sphygmomanometer. First, the validation status of each device was assessed through the website. Hypertensive patients with automated upper arm-type BP devices were consecutively enrolled. This study aimed to evaluate the current status of home BP devices in terms of validation and accuracy. However, there are few studies addressing the reliability of home BP devices and the quality of its data. Home blood pressure (BP) monitoring offers clinically relevant information enriched with more abundant data.
