What Doctors Wish Patients Knew About Home BP Measurement

More and more doctors are recommending that people with high blood pressure, or at risk for it, learn to take their blood pressure at home. Here are some tips from the AMA on doing so:

Nearly half of adults in the United States have high blood pressure—and many don’t have their hypertension under control. But when patients measure their blood pressure regularly and share those measurements with their doctors, they are playing an important role in their care.

“It’s so important to partner with patients on improving their blood pressure. Having patients take their own BP measurements is a way to do that and engage patients in self-management of their blood pressure,” said Michael Rakotz, MD, a family physician and vice president of health outcomes at the AMA.

Here is what physicians wish patients knew about taking their own blood pressure measurements outside of the clinical setting, also commonly referred to as self-measured BP (SMBP).

“Anyone who already has a diagnosis of high blood pressure can use SMBP to track their BP over time,” Dr. Rakotz said. “The measurements can help physicians assess the effectiveness of treatments being used.”

“If a patient doesn’t have a diagnosis of high blood pressure, home measurements can be used to make an accurate diagnosis,” he said. “But it’s also important to understand that if a patient does have high blood pressure, taking home measurements alone is not an effective form of treatment.

“SMBP is something that can be used by a physician and care team to make sure that the treatment plan a patient is following is working and should be accompanied by clinical support,” Dr. Rakotz added.

“Make sure that a home BP measurement device has been validated for clinical accuracy, which means it  has been tested to make sure that it will give accurate measurements,” said Dr. Rakotz. Patients “can either look at a validated device list or they can ask their doctor for a recommendation.”

“Home blood pressure measurement devices should have upper arm cuffs and automatically inflate,” said Dr. Rakotz. “This means that you push a button to take the measurement so you don’t have to squeeze a bulb to manually inflate the cuff and use a stethoscope to obtain readings.”

“Patients also should use an upper arm cuff that is appropriately sized for their arm to get accurate measurements,” he said, adding that “home BP measurement devices typically come with a standard-sized cuff, so it’s helpful to make sure that the standard cuff fits a patient’s mid-upper arm appropriately.

“If the standard cuff does not fit, the device will not provide accurate measurements,” Dr. Rakotz added.

“Other nice features for the device to have are memory storage and for it to be Bluetooth enabled.”

“Patients should rest quietly for five minutes while sitting in a comfortable position before measuring their blood pressure,” said Dr. Rakotz. “When taking a BP measurement, patients should sit with their legs uncrossed, feet supported on the floor or a firm surface, back supported and arm supported on a firm surface with the cuff at the level of the heart—which is about mid-chest.”

“Most measurement-related errors increase blood pressure temporarily,” he said. “This can be a real problem if a physician is trying to diagnose or treat blood high blood pressure based on home readings.”

“Preparation and positioning are key to obtaining accurate measurements so physicians and care teams should educate patients on how to properly take BP measurements themselves,” said Dr. Rakotz.

“Two blood pressure measurements, one minute apart, should be taken each time home measurements are performed. Measurements should be taken in the morning and evening,” said Dr. Rakotz. “Again, that’s two blood pressure readings, one minute apart, twice daily for seven days. If all of these measurements are taken, that will add up to 28 readings in a one-week period.”

“Make sure all measurement results are shared with the physician and care team, ” he said, adding that “based on the results the physician will make treatment decisions and recommendations.”
