Pilot Study of Home Blood Pressure Control Program (eBP Control)

Pilot Study of Home Blood Pressure Control Program (eBP Control)

This intervention study will evaluate the feasibility,acceptability and effectiveness of an e-health enabled model of care by randomly assigning a trained patient navigator and/or a blood pressure (BP) self-management web portal to patients with uncontrolled hypertension after a run in period with a home BP monitor (HBPM) and comparing the results on blood pressure control. We anticipate that patients receiving the combination of a patient navigator(PN)with a self-management web portal and home BP monitor will have better BP control than when the only received a home BP monitor.

The study will demonstrate and evaluate the feasibility and acceptability of an e-health enabled model of care for improved hypertension and elevated blood pressure control using a home blood pressure monitor (HBPM), a blood pressure (BP) self-management web portal, and a trained patient navigator. During the first or the control period, all of the participants will have access to the only the HBPM. The control period will be compared to the final or the intervention period when the participants will gain access to a trained patient navigator and the web portal. This comparison will assist in estimating the effect sizes of the HBPM plus PN plus self-management web portal to HBPM alone for each of the outcomes: patient activation, self-management activities, medication adherence, reduced clinical inertia, and improved BP control. The second of the randomization periods will allocate a patient navigator to half of the participants, while the other half will gain access to only the web portal. We will compare the effectiveness of the PN plus webportal plus HBPM to webportal plus HBPM during this second period. An evaluation of the intervention process will delineate the barriers and facilitators by the providers, participants, and patient navigators.
