Purpose:

The purpose of this study is to evaluate the impact of physician/pharmacist collaborative teams on hypertension guideline adherence for patients with uncontrolled hypertension in six family medicine practice sites in Iowa.


Study summary:

BACKGROUND: Hypertension is a prevalent chronic condition that, if left untreated, can lead to significant cardiovascular morbidity and premature mortality. There are established, evidence-based guidelines for the treatment of hypertension. However, these guidelines are not routinely adhered to by all providers for reasons that are not well known or understood. In addition, inadequate control of BP nationwide has been well documented. This study will explore barriers to guideline adherence (Phase I) and evaluate, via a randomized controlled trial, a new approach to enhancing guideline adherence and ultimately BP control. DESIGN NARRATIVE: The long-range goal of the principal investigator is to develop and evaluate collaborative relationships between physicians and pharmacists that improve pharmacotherapy. This will be a 5-year, multicenter study to evaluate the impact of physician/pharmacist collaborative teams on adherence to hypertension guidelines (JNC-VI) in six community-based family practice sites. There will be two study phases. Phase I comprises a needs assessment to identify barriers to guideline adherence and design intervention implementation refinement strategies. Phase II will be a prospective, randomized trial to assess the impact of physician/pharmacist collaborative teams on hypertension guideline adherence and BP control. The specific aims of Phase I are (1) to identify the scope and nature of physician and patient variables that may contribute to poor guideline adherence and (2) to refine the intervention implementation strategy and design tools for assessing guideline adherence and barriers to adherence. The specific aims of Phase II are (1) to determine if there is a change in guideline adherence and knowledge of hypertension when physicians are involved in physician/pharmacist teams and 2) to determine if physician/pharmacist teams can achieve better BP control compared to usual care. The investigators expect that the improvement in guideline adherence and reduction in BP with this intervention will significantly impact patients with hypertension. Because there are more than 37 million Americans with uncontrolled hypertension, this model has the potential to become an important strategy to help achieve the BP goals for Healthy People 2010.
