Exploring methodology for investigating Chinese coronary artery disease patient values and preferences: A methodological study protocol.

This study describes a planned research project focused on understanding what matters most to Chinese patients with coronary artery disease (CAD) - a condition where arteries supplying blood to the heart become narrowed or blocked. Researchers are developing a systematic way to ask CAD patients about their treatment preferences, particularly regarding blood-thinning medications that reduce heart attack risk but increase bleeding risk. The study doesn't involve acupuncture treatment but rather focuses on creating questionnaires to determine the 'minimal important difference' (MID) - essentially, how much improvement in outcomes like reduced chest pain or bleeding risk patients consider truly meaningful. The research team is using a three-phase approach: first identifying which health outcomes matter most to patients through literature review, then developing clear descriptions of these outcomes through patient interviews, and finally creating questionnaires that patients can easily understand and complete. By conducting cognitive interviews where patients think aloud while answering questions, researchers will refine the materials to ensure clarity. This methodological work aims to establish standardized tools for gathering patient preferences, which can then inform clinical treatment guidelines. While this particular study doesn't directly involve acupuncture, understanding patient values and preferences is relevant across all healthcare disciplines. If you're considering any complementary therapy including acupuncture for heart-related conditions, consult with a qualified, licensed acupuncturist who can coordinate care with your cardiologist.

This methodological protocol outlines the development of standardized instruments to assess minimal important differences (MIDs) and patient values in Chinese coronary artery disease populations. The research employs a three-phase approach: (1) identifying key patient-important outcomes through literature review and multidisciplinary consensus, (2) developing outcome descriptions via evidence synthesis from clinical guidelines and qualitative studies with supplemental patient interviews, and (3) designing outcome-specific MID questionnaires validated through iterative cognitive interviews. No sample sizes or effect sizes are reported as this is a protocol paper describing methodology rather than presenting results. The study addresses critical methodological challenges in directly surveying patients to establish MIDs for outcomes balancing antithrombotic benefits against bleeding risks. Clinical relevance: This work will provide validated tools for incorporating patient preferences into guideline development, supporting shared decision-making frameworks applicable across integrative cardiovascular care settings. The methodology may inform similar patient preference research in other chronic conditions managed with complementary and conventional approaches.
