Comprehensive Approaches to Cholesterol Management Beyond Medication Adherence

Recent research conducted by pharmacy experts at the National University of Singapore emphasizes the importance of multi-faceted strategies for effective long-term cholesterol control. While lipid-lowering medications (LLMs) are proven to reduce cholesterol levels and prevent cardiovascular diseases, issues with medication adherence remain a significant challenge, with many patients either inconsistently taking their medication or discontinuing it prematurely.

To better understand how to improve adherence and sustain cholesterol management, a systematic review led by Associate Professor Doreen TAN Su-Yin analyzed over 21,000 scientific abstracts published between 2016 and 2024. Out of these, 35 studies were selected for detailed analysis, revealing that single-component interventions, such as educational efforts or reminders alone, often result in only short-term improvements lasting less than six months.

The review highlights that the most effective interventions involve complex behavioral modifications tailored to individual motivations, combined with encouragement and regular follow-up by healthcare professionals. These multi-component strategies are aligned with the World Health Organization's five dimensions of medication adherence—behavioral, educational, administrative, condition-related, and healthcare system factors. Incorporating this holistic view addresses multiple barriers to adherence, including provider engagement and systemic factors.

However, despite initial improvements in adherence, these approaches often fail to produce sustained reductions in cholesterol levels, underscoring the limitations of focusing on a single aspect of adherence. The study advocates for integrated, system-level interventions that encompass clinician involvement, patient education, and psychosocial support, with assessments using both objective measures like prescription refill rates and subjective tools such as patient beliefs surveys.

Prof. Tan summarized, “To achieve lasting health benefits, collaborative and comprehensive strategies are necessary. Our findings suggest that addressing multiple factors simultaneously can lead to more durable improvements in medication adherence and cholesterol management.” Future efforts should also explore non-pharmacological approaches and clinician prescribing behaviors to maximize patient outcomes.

This research underscores the need for health systems to adopt a more holistic approach, moving beyond isolated interventions to systemic solutions that support sustainable cholesterol control.
