Validation of Uright model TD 3127AT wireless-portable ambulatory blood pressure monitoring device with timer trigger modification, standard cuff size, in normotensive and mild hypertensive patients of Thailand registry (Thai valid ambulatory blood pressure monitoring)

Abstract

Background: Nowadays, automated blood pressure (BP) monitoring devices are commonly used by patients as a part of standard medical care for hypertension. The timer trigger was modified into a wireless automated home BP monitoring (HBPM) device to expand its potential use as ambulatory BP monitoring. However, the BP measurement accuracy in this modified device remains unknown.

Objective: We aimed to assess the accuracy of Uright model TD 3127AT, which is an automated HBPM device with a timer trigger modification, following an International Organization for Standardization (ISO) 81060-2:2018 guidelines in the Thai population.

Methods: This cross-sectional study included normotensive and hypertensive Thai participants following the ISO 81060-2:2018 guidelines from August 2021 to February 2022. This study aimed to compare the BP readings from an automated sphygmomanometer, Uright model TD 3127AT, TaiDoc Technology Corporation, with a timer trigger to a standard manual BP measurement.

Result: BPs were measured in 85 participants with a mean age ± SD of 38.39 ± 13.91 years, and 69% were females. The mean SBP ± SD (range) was 117.46 ± 18.63 (84-176) mmHg and the mean DBP ± SD (range) was 74.84 ± 10.70 (42-108) mmHg. The mean BP difference between observers and devices was 0.66 ± 6.81 mmHg for SBP and -0.96 ± 6.33 mmHg for DBP. The SD of the averaged pair determination per individual was ±4.45 mmHg for SBP and ±3.46 mmHg for DBP. The accuracy of the timer-triggered device was found to be acceptable when evaluated according to the ISO 81060-2: 2018 guidelines.

Conclusion: An automated sphygmomanometer, Uright model TD 3127AT, TaiDoc Technology Corporation, with timer trigger modification passed the ISO 81060-2:2018 guidelines.
