We sought to catalog and extensively describe all VA funded studies conducted over the past decade focusing on adherence to antihypertensive medications, therapeutic intensification, or both. We also included non-VA funded studies focused on the care of veterans receiving health care in VA. We aimed to describe gaps in current research and identify important areas for future research, synthesize results from the studies, whether published or unpublished, in the form of an evidence synthesis, and to build on these efforts to develop more formal exchange and collaboration among VA researchers and clinicians working on addressing these important issues.
