Key result
Insufficient pre-measurement rest inflates systolic blood pressure by ~10 mmHg across oscillometric monitors.
Why the study?
Under narrow hypertension threshold margins, measurement accuracy is decisive, but detailed data on systematic and random errors under repeated testing conditions in clinical practice remain limited.

Insufficient pre-measurement rest and inter-device discrepancies can cause clinically relevant errors in blood pressure measurement, highlighting the need for standardized resting periods and repeated assessments.

Inadequate rest and device discrepancies may inflate BP readings and hypertension diagnoses; Level 4 data leaves open prospective standardization needs.
The implementation of different hypertension thresholds (e.g. ESC/ESH: 140:90 or ACC/AHH: 130:80) substantially increased hypertension prevalence donation of pharmacological treatment across various populations. Under narrow margins of only 10mmHg, measurement accuracy and reliability become decisive for clinical decision-making. However, detailed information on systematic and random errors naturally occurring in clinical practice under repeated testing conditions remain widely limited. To provide practically relevant insights, 65 participants were recruited for visited the lab four times with one un-standardized arrival measurement to mimic oftentimes observed clinical real-world scenarios followed by four standardized measurements performed in adherence with current guidelines. Tests were performed with two certified blood pressure devices, each on two testing days to quantify intra- and interday, as well as interdevice measurement errors via relative reliability and systematic and random measurement errors. Insufficient pre-measurement rest periods caused clinically relevant systematic blood pressure enhancements. Within a subsequent 10–18 min rest, the blood pressure was reliably reduced with about 10 mmHg on both days and both devices. However, the Boso Medicus testing device showed consistently higher blood pressure values with 13mmHg compared to the Welch Allyn monitor. Although measurements could be replicated inter-day in both devices, substantial interdevice discrepancies and clinically relevant random errors were observed, that can cause false-positive hypertension diagnoses, especially when pre-measurement rest was insufficient. Results underscore the relevance of performing several blood pressure assessments (per day and on different days) to account for random measurement errors and reduce the risk of inappropriate clinical decision-making and unnecessary treatment escalation.

Warneke et al. (2026) conducted an observational in Healthy adults (Blood pressure measurement error analysis) (n=65). Oscillometric blood pressure measurement (Boso Medicus vital vs Welch Allyn ProBP 2000) vs. Unstandardized arrival measurement vs standardized resting measurement was evaluated on Systolic blood pressure difference between devices at baseline (Day 1) (MD 12.5 mmHg, p=<0.001). Insufficient pre-measurement rest caused clinically relevant blood pressure elevations of ~10 mmHg, and the Boso Medicus device yielded systematically higher systolic blood pressure values by 11-13 mmHg compared to the Welch Allyn monitor.
