Featured news - Doctors raise blood pressure in patients - University of Exeter
Doctors routinely record blood pressure levels that are significantly higher than levels recorded by nurses, the first thorough analysis of scientific data has revealed.
A systematic review led by the University of Exeter Medical School, and supported by the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care in the South West Peninsula (NIHR PenCLAHRC), has discovered that recordings taken by doctors are significantly higher (by 7/4mmHg) than when the same patients are tested by nurses.
Dr Christopher Clark, of the University of Exeter Medical School, said the findings, published in the British Journal of General Practice, should lead to changes in clinical practice. “Doctors should continue to measure blood pressure as part of the assessment of an ill patient or a routine check-up, but not where clinical decisions on blood pressure treatment depend on the outcome. The difference we noted is enough to tip some patients over the threshold for treatment for high blood pressure, and unnecessary medication can lead to unwanted side-effects. Some patients may be erroneously asked to continue to monitor their own blood pressure at home, which can build anxiety. These inappropriate measures could all be avoided by the simple measure of someone other than a doctor taking the blood pressure recording.”
“Researchers should also think carefully about how to account for this effect in studies that compare treatment by doctors and nurses. Some studies have concluded that nurses are better at treating hypertension, when in fact those findings could be down to this recording bias.”
