The in-person postpartum blood pressure check: For whose benefit?

Solution 2: The algorithm-driven system

“Sure. Plug your numbers into our system, and you’ll receive an automated response as to what to do next.”

One way to alleviate both the financial and opportunity cost of constant clinician surveillance would be to offload some tasks to algorithmic support. This approach—home BP monitoring accompanied by self-titration of antihypertensive medication—has been validated in outpatient primary care hypertension management in nonpregnant adults and more recently for postpartum patients as well.

In the SNAP-HT trial, investigators randomly assigned women to either usual care or algorithm-driven outpatient BP management.⁸ While both groups had serial visits (for safety monitoring), those in the experimental arm were advised only by the algorithm for any ongoing titration of medication. At 6 weeks, the investigators found that BPs were lower in the intervention group, and diastolic BPs remained lower at 6 months.

This methodology emphasizes the potential utility of true self-management of hypertension in the postpartum period. It relies, however, on having a highly developed system in place that can receive the data, respond with recommendations, and safely monitor for any aberrations in the feed. Still, this hybrid method may represent the sweet spot: a combination that ensures adequate surveillance while not overburdening the clinician with the simpler, initial steps in postpartum antihypertensive management.

Solution 3: The DIY system

“That’s a good point. I want to hear about your blood pressure readings in the meantime. Here’s what we can do.”

What about the 99% of practicing ObGyns who do not have an entire connected system for remote hypertension monitoring? A number of options can be put in place today with little cost and even less tech know-how (see “Do-it-yourself options for remote blood pressure monitoring,” below). Note that since many of these options would not be monitored in “real time” like the connected systems discussed above, the patient should be given strict parameters for contacting her clinician directly. These do-it-yourself, or DIY, methods are instead best for the purpose of chronic monitoring and medication titration but are still an improvement in communication over the single-serve BP check.

The bottom line

Pregnant women represent one of the most connected, Internet-savvy demographic groups of any patient population: More than three-quarters of pregnant women turn to the Internet for advice during their pregnancy.^9,10 In addition, unlike most social determinants of health, such as housing, food access, and health care coverage, access to connected electronic devices differs little across racial lines, suggesting the potential for targeting health care inequities by implementing more—not less—technology into prenatal and postpartum care.

For this generation of new mothers, the in-office postpartum BP check is insufficient, artificial, and simply a waste of everyone’s time. While there is no one-size-fits-all approach, there are many options, and it is up to us as health care providers to facilitate the right care, in the right place, at the right time for our patients. ●
