Key result
Unattended automated office BP yields systolic readings ~4 mmHg lower than attended measurements.
Why the study?
The study compared unattended, attended, and routine clinic systolic BP and investigated the role of measurement sequence and attended automated BP thresholds on BP differences.
Does unattended automated office blood pressure measurement yield different systolic blood pressure readings compared to attended and routine clinic measurements?

Does unattended automated office blood pressure measurement yield different systolic blood pressure readings compared to attended and routine clinic measurements?
Unattended automated office blood pressure measurements are significantly lower than both attended and routine clinic measurements, with differences influenced by measurement sequence and baseline blood pressure levels.
Answers are grounded in this paper and cite their sources.
May warrant caution interpreting aAOBP or clinic BP as they overestimate uAOBP; leaves open optimal sequence standardization.

Todd et al. (2026) conducted an RCT in Hypertension and cardiovascular comorbidities (n=85). Unattended automated office blood pressure (uAOBP) vs. Attended automated office blood pressure (aAOBP) was evaluated on Systolic blood pressure (Mean difference 4.12 mmHg, p=<0.001). Unattended automated office systolic blood pressure was lower than attended measurements by a mean difference of 4.12 mmHg.
