Should Blood Pressure Measurement Be Repeated During Primary Care Visit?
MedicalResearch.com Interview with: Doug Einstadter, MD, MPH Center for Health Care Research and Policy MetroHealth System and Case Western Reserve University MedicalResearch.com: What is the background for this study? Response: Despite the recognized importance of blood pressure (BP) control for those with hypertension, based on national surveys only 54% of patients with hypertension seen in primary care have their BP controlled to less than 140/90 mm Hg. Blood pressure measurement error is a major cause of poor BP control. Reducing measurement error has the potential to avoid overtreatment, including side effects from medications which would be intensified or started due to a falsely elevated blood pressure. One way to reduce measurement error is to repeat the BP measurement during an office visit. The American Heart Association recommends repeating a blood pressure at the same clinic visit with at least 1 minute separating BP readings, but due to time constraints or lack of evidence for the value of repeat measurement, busy primary care practices often measure BP only once. Repeating the BP at the same office visit when the initial blood pressure measurement is high has the potential to improve clinical decision-making regarding BP treatment. Several studies have described the effect of a repeat BP measurement in the inpatient setting, but there are little data available to characterize the effect of repeating blood pressure measurement in an outpatient primary care setting.
