Canadian GPs overdiagnosing hypertension

Around a fifth of Canadian patients receiving treatment for hypertension don't actually have a problem and do not need medication, research reveals.

This is primarily because blood pressure is being improperly measured, argues the lead author of the report.

Dr Janusz Kaczorowski, a Canadian medical sociologist, says more than half of GPs in Canada are still using manual equipment, despite national guidelines recommending they use oscillometric devices.

Specifically, he says 52% of primary care doctors are preferring to stick with the older-style manual tensiometer to measure blood pressure.
