From awareness to adoption: a panoramic perspective on the utilization of Internet Medical Services among Chinese patients with chronic disease

IMS adoption is governed by multidimensional determinants beyond access, including cognitive, socio-economic, and other factors. Counterintuitive patterns (e.g., affluent patients' rejection of Online Health) necessitate tiered interventions, such as eHealth literacy programs for vulnerable groups, service standardization to mitigate distrust, and regulatory frameworks to ensure data security. This study's dual-method framework (matrix analysis and SEM) critically delineated barrier typologies through staged decomposition, establishing an evidence-based scaffold for optimizing digital health equity.
