This study focuses on an important patient behavior, medication-taking, and important
physician behaviors: promoting medication regimen adherence in patients and appropriately
modifying therapy when existing therapy results in inadequate therapeutic effect. The study
will also explore the caregivers' (clinicians) behavior after relevant information about
their patients' medication adherence and blood pressure control has been provided to them.
The investigators focus on behavior change for patients and physicians and seek to change
their behaviors to improve the health care delivery process and outcomes. The study aims at
facilitating tertiary prevention of cardiovascular, cerebrovascular, and reno-vascular
diseases by promoting better blood pressure control.
