Abstract HUP9: Assessing Adaptations of a Complex Secondary Stroke Prevention Intervention

Abstract

Introduction: S econdary stroke prevention by U niting C ommunity and C hronic care model teams E arly to E nd D isparities (SUCCEED) was a randomized trial of a multilevel complex intervention to enhance risk factor control after stroke. Subjects randomized to intervention were managed by an advanced practice clinician (APC)-community health worker (CHW) team. Within the framework of ≥3 clinic and ≥3 home visits, and Chronic Disease Self-Management Program (CDSMP) workshops, the team tailored the intervention to meet participants’ needs. To describe how the intervention was implemented and adapted, we used the form/function framework. Methods: We identified key domains (overall goals of intervention), motivating needs (importance of targeting each domain), functions (methods for addressing motivating needs), and forms (tools, resources, methods for accomplishing each function). Two study leaders conducted semi-structured interviews with 4 APCs and 4 CHWs to identify forms used. APCs and CHWs described how frequently they used each form and usefulness via a RedCap survey. Descriptive statistics were subsequently run with R version 4.2.3. Results: SUCCEED targeted 7 domains: medication adherence, stroke literacy, self-management skills, care coordination, healthcare system navigation, social support, and addressing barriers. Each domain had 1-7 motivating needs and 4-13 functions. Each function had 5-23 forms, resulting in a total of 365 forms for addressing all domains. Most providers (85%) reviewed medication bottles to assess medication adherence, strongly agreeing this was useful. Pill organizers and stickers were used 53% of the time to ensure patients knew what medications they should be taking; 71% strongly agreed this was useful. Providers identified physical/environmental/social/literacy barriers during both home visits and CDSMP workshops (71%); all providers found this combination helpful. Conclusion: The form/function framework is useful for describing real-world adaptations of complex interventions. We identified key aspects of the intervention that providers used frequently and found useful, to inform future development of secondary stroke prevention interventions.
