Key result
Aneroid sphygmomanometers had a significantly higher rate of pressure scale errors exceeding ±3 mmHg compared to mercury and automated devices (53.2% vs 7.8%, P=0.002).
Why the study?
What is the accuracy of the pressure scale of sphygmomanometers in clinical use within primary care?

What is the accuracy of the pressure scale of sphygmomanometers in clinical use within primary care?
Absolute Event Rate: 53.2% vs 7.8%
p-value: p=0.002
A significant proportion of sphygmomanometers in primary care, particularly aneroid devices, have pressure scale errors exceeding recommended thresholds, highlighting the need for regular calibration.
Coleman et al. (2005) conducted a cross-sectional in Blood pressure monitoring (n=279). Aneroid sphygmomanometers vs. Mercury and automated sphygmomanometers was evaluated on Pressure scale errors exceeding ±3 mmHg (p=0.002). Aneroid sphygmomanometers had a significantly higher rate of pressure scale errors exceeding ±3 mmHg compared to mercury and automated devices (53.2% vs 7.8%, P=0.002).
