Objective To determine whether self‐initiated and recorded automated blood pressure measurement can provide an accurate estimate of ambulatory blood pressure in pregnant women suspected of having ‘white coat hypertension’. Design A prospective observational study. Setting Women's and Children's Health Unit, St George Hospital, a teaching hospital of the University of New South Wales. Population Pregnant women being assessed for possible ‘white‐coat hypertension’. Methods Sixty‐six pregnant women who were undergoing 24 hour ambulatory blood pressure monitoring (ABPM) in their home or work environment also measured their blood pressure six times during this interval using a self‐initiated automated blood pressure recorder (Omron HEM 705CP). Agreement between awake ABPM and Omron recorded blood pressures was tested by Bland–Altman analysis. Main outcome measure Limits of agreement between blood pressures measured by each device. Results Average blood pressures obtained by the two devices were identical (125/77 mmHg) but limits of agreement were wide, −20 to +23 mmHg for systolic blood pressure and −9 to +15 mmHg for diastolic blood pressure. Conclusion The Omron HEM 705CP is a useful device for measuring group average blood pressures in pregnant women suspected of having white coat hypertension but cannot reliably replace ABPM for clinical management of individual pregnant women.
