Key result
Automated office blood pressure is recommended over conventional auscultation to avoid white coat errors.
Why the study?
Conventional auscultatory blood pressure measurement methods are prone to errors such as the white coat phenomenon, and mercury and aneroid devices are no longer recommended by the WHO.
Are automated oscillometric devices more accurate than conventional auscultatory methods for office blood pressure measurement?

May support automated office BP to reduce errors; leaves open feasibility amid cost and space barriers.
The conventional auscultatory methods for measuring blood pressure have been used to screen, diagnose, and manage hypertension since long. However, these have been found to be prone to errors especially the white coat phenomena which cause falsely high blood pressure readings. The Mercury sphygmomanometer and the Aneroid variety are no longer recommended by WHO for varying reasons. The Oscillometric devices are now recommended with preference for the Automated Office Blood Pressure measurement device which was found to have readings nearest to the Awake Ambulatory Blood Pressure readings. The downside for this device is the cost barrier. The alternative is to use the simple oscillometric device, which is much cheaper, with the rest and isolation criteria of the SPRINT study. This too may be difficult due to space constraints and the post-clinic blood measurement is a new concept worth further exploration.

Siddique et al. (2021) conducted a review in hypertension. Automated Office Blood Pressure measurement vs. conventional auscultatory methods was evaluated. Automated Office Blood Pressure measurement is recommended over conventional auscultatory methods to avoid errors like the white coat phenomenon, though cost and space constraints remain barriers.
