Only 20.0% of surveyed healthcare professionals accurately measured blood pressure according to guidelines, despite 83.9% expressing trust in their clinic's blood pressure readings.

Despite high confidence in clinical blood pressure readings, only a small minority of cardiologists and other healthcare professionals perform BP measurement accurately according to guidelines.
Accurate blood pressure (BP) measurement is essential for the diagnosis and management of hypertension. In clinical practice, BP is estimated using noninvasive methods with significant variability of application of guidelines in clinical practice, impacting the accuracy and certainty of BP measurements. We sought to assess how BP is measured in clinical practice. A survey was administered through professional societies that included predominantly cardiologists. Assessment of adherence to guideline recommendations for BP assessment was measured and compared to the level of confidence in clinic BP measurement. There were 571 surveys completed. The majority of respondents were cardiologists (61.1%), with 47 preventive cardiologists. BP was routinely checked in both arms by 53% at the initial visit, 48% check BP once each visit, and 64% wait 5 min before initial BP assessment. Automated BP assessment is used by 58% respondents. The majority (83%) trust their BP readings, and those who trust their BP readings are more likely to perform the initial BP assessment themselves, compared to those who do not trust the clinic BP readings (30.2% vs. 13.6%, P = 0.009). Accurate BP measurement is performed by 23% of cardiologists, and more likely performed accurately by a preventive cardiologist (38.3%) compared with other cardiologists (20.0%, P = 0.007). Accurate BP measurement is more likely for those who perform the initial BP themselves rather than any other staff (36.8% vs. 17.9%; P<0.001); and for those who repeat BP manually (80% vs. 54%; P<0.001), compared to those who do not measure BP accurately. Despite the inaccuracy of BP measurement, there is a high level of confidence in the BP readings. Accurate BP assessment continues to remain suboptimal in clinical practice. Reliability of BP assessment requires education, identifying barriers to implementation of recommendations and engagement of the entire team to improve BP assessment.
Gulati et al. (Thu,) conducted a cross-sectional in Blood pressure measurement practices (n=571). Survey of clinical blood pressure measurement practices was evaluated on Accurate blood pressure assessment (checking both arms, ≥2 times per visit, waiting 5 minutes). Only 20.0% of surveyed healthcare professionals accurately measured blood pressure according to guidelines, despite 83.9% expressing trust in their clinic's blood pressure readings.
