title: Sustainability of improvements in medication adherence through a mobile health intervention.
abstract: Context-Very few patient-centered, theory-guided programs for medication adherence and blood pressure control have been conducted in kidney transplant recipients. Objective-To evaluate preliminary indications of sustainability of improved blood pressure in kidney transplant recipients 12 months after completion of a 3-month randomized controlled trial of a mobile health pilot program to improve blood pressure and medication adherence. Participants and Design-A total of 18 of the 19 trial participants were contacted and all consented to inclusion in the retrospective analysis of their medical records showing their clinic-recorded systolic blood pressures at 3, 6, and 12 months following participation in the 3-month trial of a medical regimen self-management intervention. Results-A significant group difference in systolic blood pressure was observed longitudinally, indicating that the intervention group, as compared with the standard-care group, exhibited lower clinic-measured systolic blood pressures at the 12-month posttrial follow-up visit (P= .01). At 12-month follow-up, success in establishing and sustaining control of systolic blood pressure (<131 mm Hg) was greater in the intervention group (50%) than in the control group (11%). Conclusion-Patients in the intervention group continued to exhibit lower systolic blood pressure than did patients in the control group 12 months after the trial ended, suggesting that the intervention may have a durable impact on blood pressure control that most likely reflects sustained medication adherence. These findings will aid in the development of an adequately powered randomized controlled trial to address the sustainable impact of the intervention program on medication adherence and blood pressure control.
