Using the Practical Robust Implementation and Sustainability Model (PRISM) to Identify and Address Provider-Perceived Barriers to Optimal Statin Prescribing and Use in Community Health Centers

Abstract

Statins are an important but underutilized therapy to prevent cardiovascular events, particularly in high-risk patients. To increase use of statin therapy in high-risk patients, the Centers for Disease Control and Prevention funded a project led by the National Association of Community Health Centers to discover reasons for statin underuse in health centers and identify possible leverage points, particularly among vulnerable and underserved patients. The project further sought to develop training and educational materials to improve statin prescribing for and acceptance in eligible high-risk patients. As a first step, investigators implemented a questionnaire to clinical providers (n = 45) at health centers participating in the project to obtain their perspective on barriers to optimal statin use. We used the practical robust implementation and sustainability model (PRISM) domains to frame the overall project and guide the development of our questionnaire. This paper summarizes top perceived barriers to patient and health system/provider statin initiation and sustainment, as well as facilitators to prescribing, using PRISM as an organizing framework. Our questionnaire yielded important suggestions related to public awareness, education materials, health information technology (HIT)/data solutions, and clinical guidelines as key factors in optimizing statin use. It also informed the design of patient education resources and provider training tools. Future directions include using the full application of the PRISM implementation science model to assess how well our educational and training resources help overcome barriers to statin use in high-risk patients, including evaluating how key contextual factors influence successful implementation.
