Abstract

OBJECTIVE:

The present study aimed to evaluate the accuracy of the automated oscillometric upper-arm blood pressure (BP) monitor A&D UA-1020 with two different-shaped cuffs for home BP monitoring according to the British Hypertension Society (BHS) Protocol.

METHODS:

We recruited individuals for each of the two cuffs (D-ring and cylindrical) until there were 85 eligible participants (255 pairs of comparisons) and their BP could meet the BP distribution requirements specified by the BHS Protocol. For each participant, we sequentially measured the systolic and diastolic BP using a mercury sphygmomanometer (two observers) and the UA-1020 device (one supervisor).

RESULTS:

For the D-ring cuff, the device achieved grade A. The percentage of BP differences within 5, 10, and 15 mmHg was 67, 87, and 96%, respectively, for systolic BP, and 70, 90, and 99%, respectively, for diastolic BP. The average (±SD) of the device-observer differences was -0.2±7.3 mmHg (P=0.64) and 1.7±5.8 mmHg (P<0.0001) for systolic and diastolic BP, respectively. For the cylindrical cuff, the device also achieved grade A. The percentage of BP differences within 5, 10, and 15 mmHg was 67, 88, and 97%, respectively, for systolic BP and 64, 89, and 98%, respectively, for diastolic BP. The average of the device-observer differences was -0.1±7.0 mmHg (P=0.89) and 2.0±6.3 mmHg (P<0.0001) for systolic and diastolic BP, respectively.

CONCLUSION:

The UA-1020 device has passed the requirements of the BHS Protocol with both the D-ring and the cylindrical cuffs, and hence can be recommended for home use in adults.
