Key result
Automated blood pressure measurements taken while the patient rested alone (142/80 mmHg) were significantly lower than manual mercury sphygmomanometer readings (163/86 mmHg, P<0.001).
Why the study?
Does automated blood pressure measurement reduce the white-coat effect compared to a conventional mercury sphygmomanometer in patients with hypertension?
Population
50 consecutive patients referred to a specialist for management of hypertension.
Comparison
Automated blood pressure measurement using the… vs Conventional mercury sphygmomanometer.
Design

Automated blood pressure measurement taken while the patient rests alone significantly reduces the white-coat effect compared to manual mercury sphygmomanometer readings.
Martin G. Myers (2006) conducted an RCT in Hypertension (n=50). Automated blood pressure recorder (BpTRU) vs. Conventional mercury sphygmomanometer was evaluated on Mean systolic blood pressure (mmHg) (p=<0.001). Automated blood pressure measurements taken while the patient rested alone (142/80 mmHg) were significantly lower than manual mercury sphygmomanometer readings (163/86 mmHg, P<0.001).
