Abstract:
BACKGROUND: A reliable, well-validated home blood pressure(BP) self measurement device could have an important role in the management of hypertension. Rigorous assessment of such a device have not performed well, particularly in the hypertensive range. METHODS: We assessed the National EW274W device(oscillometric) for home messurem of BP according to the standards set out by the British Hypertension Society protocol and American Association for the Advancement of Medical Instrumentation(AAMI). The device was compared with sequential measurements using a standard mercury sphygmomanometer in the same arm in 105 patients aged 16-79 years. The BP of subjects was measured three times at least a week apart. These data were analysed using Pearson's correlation and paired t-test. RESULTS: The device was highly correlated to mercury sphygmomanometer in mean systolic BP(SBP) and mean diastolic BP(DBP) (r=0.93, r=0.93, P<0.05). The device was satisfactory over the whole BP range(SBP 106-182mmHg, DBP 56-116mmHg), with a B grade for SBP and a A grade for DBP(British Hypertension Society protocol) and a PASS for both SBP and DBP(AAMI). Sensitivity and specificity are 84.2%, 93.0%(mean SBP) and 100%, 96.9% (mean DBP). CONCLUSIONS: We concluded the wrist blood pressure meter(National EW274W) for home BP measurement is highly satisfactory and is suitable for clinical use.
