WEDNESDAY, April 18, 2018 (HealthDay News) — Randomization to use of a smartphone app is associated with a small improvement in medication adherence but no change in systolic blood pressure among individuals with poorly controlled hypertension, according to a study published online April 16 in JAMA Internal Medicine<\/i>.<\/p>\n
Kyle Morawski, M.D., M.P.H., from the Center for Healthcare Delivery Sciences in Boston, and colleagues recruited 412 participants with confirmed uncontrolled hypertension taking one to three antihypertensive medications; they were randomized to intervention or control in a 1-to-1 ratio. Participants in the intervention group were asked to download and use the Medisafe app, which includes reminder alerts, adherence reports, and optional peer support.<\/p>\n
The researchers found that the mean score on the Morisky medication adherence scale improved by 0.4 among intervention participants and remained unchanged among controls (between-group difference, 0.4; 95 percent confidence interval, 0.1 to 0.7; P = 0.01) after 12 weeks. Among intervention and control participants, the mean systolic blood pressure at baseline was 151.4 and 151.3 mm Hg; after 12 weeks, the mean systolic blood pressure decreased by 10.6 and 10.1 mm Hg among the intervention and control participants, respectively (between-group difference, \u22120.5; 95 percent confidence interval, \u22123.7 to 2.7; P = 0.78).<\/p>\n
“We found significant improvement in medication adherence, but no difference in systolic blood pressure between the intervention and control groups,” the authors write.<\/p>\n
The study was funded by an unrestricted grant from Medisafe Inc.<\/p>\n
