Abstract P324: Training and Technical Assistance to Improve Hypertension Control in Community Health Centers

Abstract

Introduction: About 47% of adults in the U.S. have high blood pressure (BP), a contributing factor to major adverse health conditions including heart attack, heart failure, and stroke. Hypertension has also been linked to worse outcomes from COVID-19 infection, resulting in higher rates of hospitalization and death. In 2021, the AHA launched the National Hypertension Control Initiative (NHCI) in 350 community health centers (CHCs). The 3-year initiative aimed to improve BP control and COVID-19 outcomes through training and technical assistance (T/TA) in CHCs with systematic, multi-sector, culturally sensitive and evidence-based interventions, including self-measured blood pressure (SMBP) monitoring. We hypothesize that T/TA with guideline-directed and evidence-based systematic processes can improve BP control in CHCs. Methods: The initiative included complementary components: patient and public education, community outreach and integration, health care professional and organization training, and project management and evaluation. Year one focused on laying a foundation of BP control fundamentals to strengthen knowledge and skills with webinars, office hours, tools, and resources. Years two and three reinforced key concepts, introduced new resources, and provided 1:1 support to CHCs, informed by ongoing evaluation. The adoption of systematic processes with evidence-based and guideline-directed practices were encouraged in CHCs. Recognizing potential differences across CHCs, several T/TA methods were deployed during phases of the initiative in anticipation of evolving CHC needs and readiness. The methods for T/TA include providing a core educational curriculum, developing and distributing customized CHC reports with individualized data, using new and existing resources, including a BP measurement policy and procedure and a BP treatment algorithm, and evaluating methods and practice findings. Early Results: Based on UDS data, overall, BP control rates increased in NHCI CHCs from 51.3% to 57.6% (as defined by the performance measure <140/90 mm Hg), demonstrating a 6.3% absolute increase and a 12.3% relative increase from 2020 to 2022. This is compared to all HRSA CHCs, where BP control rates increased from 58.0% to 63.4%, demonstrating a 5.4% absolute increase and a 9.3% relative increase from 2020 to 2022. While all NHCI CHCs started with BP control rates less than 58.9%, some health centers have demonstrated control rates higher than 70%. Discussion: T/TA with guideline-directed and evidence-based systematic processes may have contributed to increased BP control rates in CHCs. The degree of CHC progress may have been influenced by challenges and limitations, such as the impact of the COVID-19 pandemic on participation, clinical leadership engagement, CHC team staffing turnover, and technology interoperability.
