(HealthDay News) — Enhanced self-measured blood pressure (SMBP) paired with a connected smartphone application is not superior to standard SMBP for reducing BP, according to a study published online in JAMA Internal Medicine.

Mark J. Pletcher, MD, MPH, from the University of California in San Francisco, and colleagues examined whether enhanced SMBP paired with a connected smartphone application is superior to standard SMBP for BP reduction or patient satisfaction in a randomized trial conducted among 23 health systems. Eligible participants were randomly assigned to enhanced SMBP using a device that paired with a connected smartphone application or a standard device (1051 and 1050 participants, respectively).

The researchers found that from baseline to 6 months, the mean change in systolic BP was −10.8 versus −10.6 mm Hg for enhanced versus standard. The results for the secondary outcomes were mostly null, with the exception of documented attainment of BP control to lower than 140/<90 mm Hg, which occurred in 32 and 29% of the enhanced and standard groups, respectively (odds ratio, 1.15). Most of the participants in both groups were very likely to recommend their SMBP device to a friend (70% enhanced and 69% standard).

“Enhanced SMBP does not provide any additional reduction in BP, and patients would not recommend an enhanced SMBP device to their peers more than a standard device,” the authors write.
