Validation of the A&D BP UA-1200BLE device for home blood pressure measurement according to the ISO 81060-2:2013 standard

ObjectiveThe aim of this study was to validate the UA-1200BLE device using the ISO 81060-2:2013 standard.Materials and methodsIndividuals aged more than 12 years were recruited from among the outpatients and volunteers of Jichi Medical University (Tochigi, Japan). Eighty-five patients were included in the final analyses. Validation was performed using the same-arm sequence protocol as per the ISO 81060-2:2013 standard.ResultsThe device performed well against the standard; the mean and SD values for the differences between device and observed systolic and diastolic blood pressure values fulfilled both criterion 1 and criterion 2 of the standard (criterion 1: -2.626.89 and -0.90 +/- 6.63mmHg, respectively; criterion 2: -2.65 +/- 5.36 and -0.91 +/- 6.12mmHg, respectively). The Bland-Altman plots did not show any systematic variation in the error.ConclusionThe UA-1200BLE device had a high level of accuracy and fulfilled all ISO 81060-2:2013 standard requirements in adults with a wide range of arm circumference measurements. It is therefore suitable as a wireless blood pressure monitoring tool in patients with hypertension.
