New study results have suggested that a mobile app for patients with poorly controlled hypertension significantly improves treatment adherence, but not systolic blood pressure when compared to a control group.Even the most effective drug cannot help a patient who struggles to adhere to the prescribed course. Advocates for smartphone applications (apps) and other forms of mobile health (mHealth) interventions to increase adherence have promoted their use, but these tools have not been rigorously tested for efficacy.
Kyle Morawski, MD, MPH led the study evaluating the effects of the Medisafe mobile app on participants’ adherence to hypertension medication and their systolic blood pressure.
“Among modifiable risk factors, eliminating uncontrolled hypertension is estimated to have the single greatest potential to reduce cardiovascular mortality in women, and to have an effect that is second only to smoking cessation in men,” said Morawski. “While many factors contribute to poorly controlled hypertension, nonadherence is thought to account for nearly half of all such cases.”
The Medication adherence Improvement Support App For Engagement—Blood Pressure Trial was a randomized clinical trial of patients in the US with uncontrolled hypertension. The study included 411 participants, ages 18-75, with a systolic blood pressure of 140 mm Hg or greater and at least 1, but not more than 3 antihypertensive medications. Participants were randomly assigned to the intervention group (n=209) or the control group (n=202).
