Are blood pressure monitors accurate?

  The common criticism of home BP monitoring is the uncertainty about whether the data are accurate. The reported accuracy of HBP monitors varies. The BP inaccuracy may come from the operator of the device or from the device itself.

A recent cross-sectional study by Ruzicka M. et al. in 2016 included 210 patients who used home blood pressure monitors. For all patients, three measurements with the mercury Sphygmomanometer and the three measurements with the Home Blood Pressure Monitor were taken.

The study has reported that in many of these home blood pressure monitors, differences of 5 mm Hg were detected compared to the mercury sphygmomanometer. These differences can be dangerous for some patients who require constant blood pressure monitoring due to their condition. Therefore, it is suggested to reassess home blood pressure monitors.

  Previous studies by Hahn et al. and Merrick et al. had reported similar outcomes. The study by Merrick et al. in 1997 stated that the BP reading of 34% of patients was inaccurate using home blood pressure monitors. Campbell et al. observed that 35% of home blood pressure monitors were inaccurate using 4mm Hg as a threshold.

Protocols by the Association for the Advancement of Medical Instrumentation (AAMI), the British Hypertension Society (BHS), and the European Society of Hypertension are in place for pre-licensing of commercial BP devices. BP measurement devices already on the market are difficult to re-evaluate, as the process is costly and time-consuming.

However, accuracy studies for ambulatory BP monitors have also been done. Goodwin J. conducted a study in 2007 on 114 patients, which compared two different oscillometric ambulatory blood pressure monitors for accuracy. High accuracy was reported with both devices. The accuracy of these devices has also been confirmed in a study by Ronald M.D. in 1991.

  Nasothimiou E. G. conducted a further study to evaluate the accuracy differences between home BP and ambulatory BP measurements. The study reported consistency between HBP and ABP reading for the diagnosis of hypertension. Furthermore, home BP monitors had high sensitivity and specificity compared to ambulatory monitoring for diagnosing hypertension.
