Measurement errors may prompt inappropriate hypertension treatment; leaves open whether standardized protocols improve classification accuracy.
Observational
Systematic errors in blood pressure measurement, such as terminal digit preference and calibration errors, can lead to significant misclassification of hypertension status and inappropriate treatment.
Niyonsenga et al. (2008) conducted an observational in Hypertension. Terminal digit preference and sphygmomanometer calibration errors was evaluated on Proportion of false positives (falsely high BP) and false negatives (falsely normal BP). Terminal digit preference and sphygmomanometer calibration errors caused false positive and false negative blood pressure evaluations in 0.82% to 5.18% of the population.
