Study finds large number of home blood pressure monitors are inaccurate
juillet 13, 2016
A retrospective study led by Dr. Swapnil Hiremath found that almost a third of the home blood pressure monitors used by patients at The Ottawa Hospital were inaccurate. Home blood pressure devices are typically validated by the manufacturer based on AAMI standards, but are rarely checked for accuracy in the real world. The team reviewed the charts of 210 patients who brought a home blood pressure monitor to their appointment. The study published in PLOS ONE found that around 30 percent of the home monitors reported values different by 5 mm Hg compared to the gold standard mercury blood pressure gauge. Relying on these incorrect measurements could lead to over- or under-treatment of high blood pressure. The authors recommend that the accuracy of these widely-used devices should be further investigated.
