According to recent guidelines, 46% of U.S. adults have high blood pressure (i.e., hypertension). Traditionally addressed in clinical settings, only 54% of adults successfully manage their hypertension. Community–clinical partnerships that facilitate medication adherence and lifestyle changes are promising avenues to achieve population-level blood pressure control. We examined partnerships for blood pressure control in Washington State, their facilitators and barriers, and ways public health departments could foster partnerships. We conducted 41 semistructured interviews with clinic staff, community-based organization (CBO) staff, pharmacy staff, and community health workers (CHWs). The Centers for Disease Control and Prevention–adapted Himmelman Collaboration Continuum, which describes five levels of partnership intensity, guided our thematic analysis. We found variation across sectors in partnership frequency and intensity. Clinic and pharmacy staff reported fewer partnerships than CBO staff and CHWs, and mostly either low or very high intensity partnerships. CBO staff and CHWs described partnerships at each intensity level. Trust and having a shared mission facilitated partnerships. Competition, lack of time, limited awareness of resources, and lack of shared health records constituted barriers to partnership. Bringing potential partners together to discuss shared goals, increasing technological integration, and building awareness of resources may help bridge clinical and community silos and improve population-level blood pressure control.

Background: Little attention has been paid to quality improvement (QI) capacity within smaller primary care practices which comprise nearly half of all primary care settings. Strategies for external support to build such capacity include practice facilitation (PF), shared learning opportunities, and educational outreach. Although PF has proven effectiveness, little is known about the comparative effectiveness of combining these strategies. Here, we describe the protocol of the "Healthy Hearts Northwest" (H2N) study, a randomized trial designed to address these questions while improving risk factors for cardiovascular disease.Methods/design: The targeted enrollment is 250 smaller primary care practices across Washington, Oregon, and Idaho. The study is utilizing a two-by-two factorial design to assess four different combinations of practice support: PF alone, PF with educational outreach, PF with shared learning opportunities, or PF with both. A mixed methods approach is being used for evaluation and will include data from (1) baseline and follow-up practice and staff surveys; (2) baseline and quarterly clinical performance measurement from each practice on four cardiovascular risk factors: appropriate aspirin use, blood pressure control, lipid management and smoking cessation support; and (3) a quality improvement capacity assessment (QICA) survey used by external practice facilitators to guide improvement efforts.Discussion: Results from this study will inform future large-scale practice improvement initiatives by providing comparisons of promising external practice support strategies and advance our understanding of how to build QI capacity in primary care.Trial Registration: ClinicalTrials.gov, NCT02839382.
