Automated office BP measurement: The new standard in HTN screening

ILLUSTRATIVE CASE

A 45-year-old woman with no chronic medical illness presents to your office for her annual physical examination. After a medical assistant (MA) applies an automatic BP cuff to the patient’s left arm, the BP reading is 155/92 mm Hg. The MA then rechecks the BP, and this time it reads 160/98 mm Hg. The MA performs a manual BP reading, which is 158/90 mm Hg (left arm) and 162/100 mm Hg (right arm). The patient denies any headache, visual changes, chest pain, or difficulty breathing and tells the MA that her BP is always high during a doctor visit. You are wondering if she has hypertension or if is this the white-coat effect.

Depending on the definition of hypertension, its prevalence among US adults 18 years or older varies from 46%, based on the American College of Cardiology guideline (≥ 130/80 mm Hg), to 29%, based on the Eighth Joint National Committee (JNC-8) guideline (≥ 140/90 mm Hg for adults ages 18–59 years and ≥ 150/90 mm Hg for adults ≥ 60 years without diabetes and/or chronic kidney disease).2,3

According to JNC-8, the prevalence is similar among men (30.2%) and women (27.7%) and increases with age: 18 to 39 years, 7.5%; 40 to 59 years, 33.2%; and ≥ 60 years, 63.1%.3,4 When ranked by risk-attributable ­disability-adjusted life-years (DALYs), high systolic blood pressure (SBP) is the leading risk factor, accounting for 10.4 million deaths and 218 million DALYs globally in 2017.5 National medical costs associated with hypertension are estimated to account for about $131 billion in annual health care expenditures, averaged over 12 years from 2003 to 2014.6

When performed correctly, the auscultatory method using a mercury sphygmomanometer correlates well with simultaneous intra-arterial BP and was considered the gold standard for office-based measurements for many years.7,8 However, significant ­observer-related differences in auditory acuity and terminal digit rounding are sources of inaccurate measurement. White-coat hypertension cannot be detected with this method—another significant limitation. The inaccuracy of office-based BP readings leads to concerns about hypertension being inappropriately diagnosed in patients or delays in diagnosis occurring.9

A proposed solution to this problem is measurement using an oscillometric sphygmomanometer. This device uses a pressure transducer to assess the oscillations of pressure in a cuff during gradual deflation; it provides accurate BP measurements when fully automated and programmed to complete several BP measurements at appropriate intervals while the patient rests alone in a quiet room.10

The accuracy of this new method was tested in a 2009 cohort study of 309 patients referred to an ambulatory blood pressure (ABP) monitoring unit at an academic hospital for diagnosis or management of hypertension.11 The study compared mean awake ABP, which continuously measures patients’ BP throughout the day, manual sphygmomanometer readings taken by the patient’s own physician, and an automated office blood pressure (AOBP) device called BpTRU (an automated oscillometric sphygmomanometer) while the patient rested alone in the exam room.11 The awake ABP is a federally approved standard for the diagnosis of white-coat hypertension.12 In this study, the white-coat response was negated with the use of the automated BpTRU device.11

A 2019 meta-analysis that included 26 studies (N = 7116) comparing AOBP with other BP measurement techniques concluded that the use of automated oscillometric BP readings is more accurate for diagnosing hypertension and assists in negating the white-coat hypertension effect.9

STUDY SUMMARY

Automated office BP devices are just as accurate as more expensive ABP studies

This systematic review and meta-analysis (N = 9279; 23 cross-sectional, 1 cohort, and 7 randomized controlled trials [N = 1304], of which 17 studies overlapped with those included in the previously mentioned meta-analysis9) compared SBP and diastolic blood pressure measured by an oscillometric AOBP device to awake or daytime ABP (continuously monitoring BP while awake, used as a standard for BP measurement), routine manual office BP, or research BP measurements.

The study also explored the protocol by which the best AOBP results could be obtained. For AOBP measurement, the included trials had no more than 2 minutes of elapsed time between individual AOBP measurements and had at least 3 AOBP readings to calculate the mean.

Compared with AOBP, in samples with an SBP of ≥ 130 mm Hg, SBP readings were significantly higher for both routine office visits (mean difference [MD] = 14.5 mm Hg; 95% CI, 11.8–17.2) and research (MD = 7 mm Hg; 95% CI, 4.9–9.1). However, no difference was found between AOBP and awake ambulatory SBP values (MD = 0.3 mm Hg; 95% CI, −1.1 to 1.7). In all cases, heterogeneity of the included studies was high (I2 was > 75%). There was no evidence of small-study effect or publication bias, and little evidence of potential financial bias. The most accurate methodology for AOBP measurements included multiple BP readings and the patient resting alone in a quiet location.

This meta-analysis supports the use of an automated office blood pressure device to accurately screen for hypertension and avoid the white-coat effect.

Although there was statistical heterogeneity, the results were confirmed in the authors’ analysis of studies with high methodologic quality. In addition, researchers performed multiple meta-regression analyses to evaluate the statistical heterogeneity and found no significant differences based on age, body mass index, number of treated patients, gender, measurement interval, or added rest before AOBP.

WHAT'S NEW

Study confirms unattended, automated office BP as preferred technique

This is the second recent comprehensive systematic review and meta-analysis to directly compare AOBP with other common techniques of BP measurement in screening for and diagnosing hypertension in the clinical setting. 9

Continue to: This meta-analysis...

 

 

This meta-analysis emphasized the technique (see below) by which to obtain the best AOBP vs ABP results, whereas the other ­meta-analysis9 did not. Thus the study provides practice-based settings with the information they need to more closely replicate the results of the studies included in the meta-analysis.

Also, the equivalency comparison with the more expensive and intrusive ABP monitoring may save money, improve patient adherence, and increase patient satisfaction. Given these advantages, along with its demonstrated accuracy, AOBP should be adopted in routine clinical practice to screen patients for hypertension.

CAVEATS

Close adherence to measurementprocedures is a necessity

Effective use of AOBP in clinical practice requires close adherence to the AOBP study procedures described in this meta-analysis. These include taking multiple (at least 3) BP readings, 1 to 2 minutes apart, recorded with a fully automated oscillometric sphygmomanometer while the patient rests alone in a quiet place.

 

CHALLENGES TO IMPLEMENTATION

Adjusting workflows, addressing cost

Physicians may be reluctant to adopt this technique because they may not be convinced of its advantages compared with the traditional methods of recording BP and because of difficulties with implementing new rooming workflows.12 The cost of AOBP devices used in this study (Omron 907 and BpTRU; BpTRU ceased operations in 2017) were not disclosed, which may be a hindrance, as devices may cost $1000 or more.

Effective use of automated office blood pressure requires that one take multiple (at least 3) BP readings, 1 to 2 minutes apart, while the patient rests alone in a quiet place.

An online search for “automated oscillometric BP monitor” by one of the PURL authors (RCM) found oscillometric AOBP devices ranging from $150 to > $1000, depending on whether the device was medical grade; a search for “Omron 907” found devices for ≤ $599 on multiple sites. However, none of the lower-cost devices indicated the ability to take multiple, unattended BP readings.

PRACTICE CHANGER

Measure patients’ blood pressure (BP) using an oscillometric, fully automated office BP device, with the patient sitting alone in a quiet exam room, to accurately diagnose hypertension and eliminate the “white-coat” effect.

STRENGTH OF RECOMMENDATION

B: Based on a systematic review and meta-analysis of randomized controlled trials and cohort studies.1
