Clinical Impact of 3- Vs. 5-Minute Delay and 30- Vs. 60-Second Intervals on Unattended Automated Office Blood Pressure Measurements.

ABSTRACT:

Background

Guidelines advise automated office blood pressure (AOBP) with an initial 5-minute delay and multiple measurements at least 60 seconds apart. Recent studies suggest that AOBP may be accurate with shorter delays or intervals, but evidence in clinical settings is limited.

Methods

Patients referred to 1 hypertension (HTN) center underwent 24-hour ambulatory blood pressure monitoring (ABPM) and 1 of 4 nonrandomized, unattended AOBP protocols: a 3- or 5-minute delay with a 30- or 60-second interval, i.e., 3 min/30 s/30 s, 3/60/60, 5/30/30 and 5/60/60 protocols. HTN was defined as systolic blood pressure (SBP) ≥140 or diastolic blood pressure ≥90 mm Hg.

Results

We compared differences in mean blood pressure and HTN classification between average AOBP and awake-tim
