Improving blood pressure screening and control at an academic health system

The goal of the University of California Davis Health Blood Pressure (BP) Quality Improvement Initiative was to improve the diagnosis, management and control of high BP. Patients aged 18-85 years were included in the initiative. Lean A3 problem solving was used to implement the following evidence-based interventions based on stakeholder interviews, value stream mapping and the Centers for Disease Control and Prevention's Million Hearts Initiative: staff training on accurate BP measurement, visual cues and reminders for BP screening, virtual case-based videoconferences, standardised clinical management algorithm, academic detailing visits, clinical decision support tools, access to pharmacists for medication comanagement, clinician workflow modification, patient education and access to home BP monitors. Following implementation of interventions, accurate screening of BP increased from 14% to 87% and BP control increased from 62% to 75%. Strategies that contributed the most to improvements were using a team-based approach, adjusting clinic workflow and frequent communication of results to staff.
