Effectiveness of Phone Call and Video-based Interventions to Improve Adherence to Medications in Hypertensive Patients

Summary

The goal of this clinical trial is to find out if phone call and video-based interventions that seek to educate people with uncontrolled high blood pressure and also remind them to take their medicines will improve adherence to their medicines. It will also examine if the interventions are economical to implement. The main objectives of the study are:

* Design videos and phone call-based interventions for people with hypertension.
* Examine the effect of videos and phone call-based intervention on adherence to medication in people with hypertension.
* Calculate the costs associated with the mobile health intervention
* Examine the factors influencing acceptance of video and phone calls based interventions for improving adherence to antihypertensive medications among patients

Participants will:

* Receive the intervention thrice weekly for 3 months
* Visit the health facility at the end of 3 months for check up and measurement of outcome variables (adherence and blood pressure). Additionally, at the end of 3 months, the acceptability of the interventions will be measured among the participants who received either phone call or video.

Researchers will compare the two groups (one group will utilize phone call whereas the other videos) with the control group to see if the mobile interventions improve adherence to medicines. Only adults 18 years and above in selected health facilities in the Eastern will participate in the study. The selected participants should have uncontrolled blood pressure based on readings from last 2 visits. To be included in the study, the participants need to own a smartphone.
