Partnerships for Blood Pressure Control in Washington State, December 2016-July 2017.

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.
