Automatic Office Blood Pressure Measured without Doctors or Nurses Present

Backgrounds—We evaluated the agreement between office blood pressure (OBP) measured by mercury sphygmomanometer (Sphyg) and automatic (Auto) device without any observers, and compared Auto and Sphyg OBP to ambulatory (ABP) and home blood pressure (HBP). Methods—OBP was measured in 75 hypertensive patients at 2 sites using an automatic monitor without a doctor or nurse present and by Sphyg during 3 clinic visits. Between visits, ABP and HBP monitoring were also performed. Results—Mean Auto OBP was similar to Sphyg OBP and they were closely correlated (ICC=0.84 for systolic and 0.91 for diastolic OBPs); however, the difference between Auto and Sphyg systolic OBP (1.6±8.2 mmHg) varied by the first office visit, gender, and the site. Auto systolic OBP was lower than both systolic awake ABP (137.1±14.7 mmHg) and HBP (139.2±15.6 mmHg). Auto systolic OBP and Sphyg OBP were similarly correlated with systolic awake AB
