Blood pressure monitoring: Room for improvement
Date:12/12/2011

Because some clinicians fail to stick to official recommendations for blood pressure monitoring, a number of patients are misclassified, which could have an impact on decisions about their treatment. According to Gretchen Ray and colleagues, from the University of New Mexico College of Pharmacy, when routine blood pressure monitoring in clinics is compared with measurements based on the latest guidelines, 93 percent of patients have different blood pressure readings. The findings appear online in the Journal of General Internal Medicine, published by Springer.

In 2005, the American Heart Association (AHA) released updated recommendations for blood pressure monitoring, to ensure accurate and consistent blood pressure measurements. Numerous factors including body position, arm position, inter-arm differences, cuff size and cuff placement can affect the reading.

Ray and colleagues compared the blood pressure readings of 40 patients obtained by the traditional method routinely used in clinics, as well as by the AHA-recommended method. Based on these two readings for each patient, the researchers produced two medical profile summaries (one for each technique used), covering past medical history, medication list, drug allergies, vital signs, presence or absence of pain, physical examination and laboratory findings, as well as the last two blood pressure readings. These profiles were reviewed by three physicians who provided hypothetical hypertension treatment recommendations.

Ray and colleagues found that overall, individual blood pressure measurements varied greatly between the two methods. As many as 93 percent of patients had a significant blood pressure difference between the two readings (either over 5 mmHg systolic or over 2 mmHg diastolic), with implications for potential cardiovascular complications.

The researchers observed multiple technical errors during the method that most likely accounted for differences betwe
