The guideline-recommended blood pressure (BP) measurement procedure takes ~10 minutes to complete, which may not be feasible in busy clinical practices, and the evidence supporting the steps in the procedure is uneven in quality. We reviewed the latest evidence from studies that quantified the impact of streamlining certain steps in the procedure on BP measurement accuracy and precision, several of which were conducted by our team. Studies demonstrated it is possible to reduce the rest period from 5 to 0 minutes and the interval between measurements from 60 to 30 seconds without compromising accuracy. Additionally, repeating the BP measurement only when the first one is ≥130/80 mm Hg optimized accuracy and efficiency. Meanwhile, using the proper cuff size, arm support, and body positioning are critical for accuracy. We translated this evidence into a practical, streamlined protocol for BP measurement in primary care. Broad implementation would result in more efficient BP measurement without compromising accuracy or precision, thereby increasing capacity to screen, diagnose, and manage hypertension.
