Focus groups with nine Dutch primary care professionals revealed significant barriers to implementing PROSPERA, a population-level cardiovascular risk management programme that combines systematic patient outreach with individual support tools. Healthcare providers identified technological infrastructure limitations, altered professional roles, and insufficient skills in risk calculation interpretation as primary obstacles. However, facilitators emerged including provider beliefs in proactive care importance, positive patient responses to lifestyle questionnaires, and effective risk communication tools like U-Prevent. These insights illuminate a critical gap in cardiovascular prevention: while individual risk assessment tools proliferate, systematic population-level approaches remain challenging to implement in real-world primary care settings. The findings suggest that successful cardiovascular prevention programs require comprehensive support beyond clinical tools—including provider education, technological infrastructure, and workflow redesign. For adults seeking optimal cardiovascular care, this research highlights why prevention programs may vary significantly between practices. As a preprint awaiting peer review, these preliminary findings may change, but they underscore the implementation science challenges that often determine whether evidence-based interventions actually reach patients in routine care.
