Mercury sphygmomanometers are being removed from clinical practice in the United States due to environmental concerns about mercury toxicity. Accurate blood pressure measurement is central to high-quality hypertension management. In this study of 106 patients, the BpTRU™ device was compared to nurse blood pressure measurements that complied with all the JNC VII/American Heart Association guidelines in evaluation of a random casual blood pressure. The intermethod difference in systolic blood pressure was +1.8± 5.1 mmHg, and for diastolic blood pressure it was 4.8 ± 5.1 mmHg (both P±0.001). For the primary study end point of clinical decision-making, there was 92% (97/106) agreement between the hypertension nurse specialist and the BpTRU™ (kappa 0.8280, 95% confidence interval, 0.721-0.9350). The oscillometric blood pressure measurement with the BpTRU™ is recommended as a replacement for poorly performed auscultatory blood pressure measurement in clinical practice.
