This guideline represents an important step toward clarifying the evidence regarding the management of patients with hypertension within the VA/DoD primary care settings. As with other clinical practice guidelines, challenges remain, such as evidence gaps, the need to develop effective strategies for guideline implementation, and the need for strategies to evaluate the effect of guideline adherence on clinical outcomes. This guideline is primarily intended for health care practitioners in primary care, including physicians, nurse practitioners, physician assistants, pharmacists, nurses, and others involved in the care of patients with hypertension, although it may also be informative for specialty care practitioners.
