Automated BP vs Manual BP Measurement: Which is Better? (Part 2 of 2)

Doctor, nurse, and patientIn my last post, I discussed the importance of informed debate in helping determine effective clinical practice. Specifically, I mentioned two recent journal articles about automated oscillometric blood pressure devices that arrived at two different conclusions. In that post I also provided some comments from the SunTech perspective. Today, I’ll share the perspectives of an experienced, practicing physician on the subject of automated BP devices versus manual sphygmomanometers.

Automated BP vs Manual BP Measurement: Which is Better? (Part 1 of 2)

Automated or manual BP debateWhat’s a clinician to do? Debates about clinical trials, patient populations, and statistical analyses can seem hollow and distant when looking at an anxious patient in an exam room. At that moment, all that matters is what’s best for your patient. Yet clinically relevant data, and more importantly, rigorous discussion of that data, is the means to the end. Professional clinicians quite often need the former in order to effectively deliver the latter. To wit, two similar journal articles were recently published that arrived at two very different conclusions. Let’s take a look:

In the last few years, many track their own BP with the widespread availability and affordability of home monitors. Although experts in cardiology regard ambulatory blood pressure monitoring (ABPM) as the gold standard, it is not as frequently used in regular medical practice as in-office or home BP.
Each method has its benefits and disadvantages.

Physician Acquired Blood Pressure Measurement is Higher than Nurse Acquired BP

Doctor takes patient's blood pressureThere are several different types of mild and/or episodic hypertension that ambulatory blood pressure monitoring (ABPM) can help a physician diagnose. However, the summary data that ABPM provides, the average daytime or 24-hour blood pressure as two examples, provides significantly different information than the one or two measurements taken in a clinic. Although this difference is one of the reasons that ABPM correlates better to cardiovascular outcomes than in-clinic BP, making it the gold standard for BP measurement, there are few detailed guidelines on the targets or thresholds for ABP like there are for in-clinic BPs like the popular 120/80 as a threshold for normal BP and 140/90 for hypertensive.*
