Validation of the G.LAB MD41A0 upper arm blood pressure monitor in patients with diabetes mellitus according to the AAMI/ESH/ISO 81060-2:2018 Universal Standard.

OBJECTIVE

The objective of this study is to determine the accuracy of the G.LAB MD41A0 upper-arm oscillometric blood pressure (BP) monitor for self/home BP measurement in patients with diabetes according to the Association for the Advancement of Medical Instrumentation /European Society of Hypertension /International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2:2018).

METHODS

Patients with diabetes were recruited according to AAMI/ESH/ISO Universal Standard using the same arm sequential BP measurement method. The standard cuff of the test device was used for arm circumference 22-44 cm.

RESULTS

A total of 92 patients with diabetes were recruited and 85 were analyzed with an average age of 55.1 ± 17.7 years, 48 men, and arm circumference of 32.0 ± 6.0 cm. For the validation Criterion 1, the mean ± SD of the differences between the test device and reference BP readings was 0.89 ± 6.04/-0.84 ± 5.11 mmHg (systolic/diastolic). For Criterion 2, the SD of the averaged BP differences between the test device and reference BP per subject was 4.23/4.19 mmHg (systolic/diastolic).

CONCLUSION

The G.LAB MD41A0 upper arm BP monitor fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018) in patients with diabetes and can be recommended for self/home use.
