MONDAY, August 15, 2022 (HealthDay News) — Improvement in self-measured blood pressure (SMBP) associated with a connected smartphone app is not superior to standard SMBP in lowering BP, according to a study published online August 15 in JAMA internal medicine.
Mark J. Pletcher, MD, MPH, University of California, San Francisco, and colleagues investigated whether enhanced SMBP associated with a connected smartphone app is superior to standard SMBP for BP reduction or satisfaction patients in a randomized trial across 23 health systems. Eligible participants were randomly assigned to enhanced SMBP using a device paired with a connected smartphone app or a standard device (1051 and 1050 participants, respectively).
The researchers found that between baseline and six months, the mean change in systolic blood pressure was -10.8 versus -10.6 mm Hg for improvement from norm. Results for secondary outcomes were mostly nil, with the exception of documented impairment of BP control to less than 140/
“Enhanced SMBP provides no additional BP reduction, and patients would not recommend an enhanced SMBP device to their peers any more than a standard device,” the authors write.
