Is blood pressure reading more accurate at home or clinic?

Frequently taken blood pressure measurements at home may provide a more accurate diagnosis of high blood pressure than those taken at the hospital, according to a new study led by researchers Kaiser Permanente.

The results of the study came from an anonymous trial of 510 adults who visited one of the first Kaiser Permanente 12 care centers in West Washington between 2017 and 2019 published today in Journal of General Medicine.

“Blood levels vary greatly throughout the day — about 30 systolic points — and 1 or 2 measurements in the hospital may not indicate your average blood pressure,” said Beverly B. Green, MD, MPH, lead author of the study. who is a senior officer. researcher at the Kaiser Permanente Washington Medical Research Center and a doctor at the Washington Permanente Medical Center. “The new local high blood pressure allows you to collect more reading and average of these.”

To conduct the study, the researchers used them electronic health data to identify potential participants who are at risk of having hypertension in connection with a recent hospital visit. They then divided the participants into 3 groups according to the procedure to be followed to get high blood pressure: at the hospital, at home, or at kiosks in the hospital or pharmacy.

In addition to these measures, each participant received a 24-hour exercise for high blood pressure, or ABPM, a gold standard test to make a new diagnosis of high blood pressure. ABPM uses a full upper cuff equipped with a waistband that is worn for 24 hours and blows every 20 to 30 minutes during the day and every 30 to 60 minutes at night . ABPM provides the most accurate search data but is not available for multitasking. The researchers were able to assess the accuracy of the other 3 methods by comparing their results with the results of ABPM.

The study found:

  • High blood pressure readings were consistent with ABPM
  • Blood pressure readings based on subsequent clinical visits were lower for systolic measurements, resulting in more than half of people with hypertension related to ABPM missing out.
  • High blood pressure readings from kiosks are higher than ABPM-dependent levels, resulting in a higher risk of high blood pressure.

“New home hypertension is the best option, because it is more accurate than clinical hypertension studies,” says Dr. Green. “Furthermore, a partner study found that patients are more likely to carry high blood pressure at home.” The results of a cohort study were presented at a high blood pressure conference of the American Heart Association.

The number of undiagnosed high blood pressure in the United States could be in the millions. A recent study published in PEOPLE It is estimated that 23% of American high blood pressure patients are unaware that they have the condition and are not receiving treatment.

Properly diagnosed with high blood pressure can save a patient’s life. When high blood pressure is detected, doctors will usually prescribe medication to lower blood pressure. Without treatment, high blood pressure can lead to heart attack, stroke, kidney damage, and other problems.

Current guidelines for diagnosing high blood pressure suggest that patients who have high blood pressure readings in the hospital should try again to confirm the results. While guidelines recommend ABPM or local hypertension management prior to diagnosis of hypertension, research has shown that providers continue to use the measure in the hospital during the second study.

While previous research has found similar benefits for home blood pressure reading, this may provide the strongest evidence to date due to the large number of conference participants, admission to primary care hospitals, and the use of international medical professionals to take over. high blood pressure measures instead of research staff. Also, this study is the first to compare kiosk with ABPM results.
