简要总结
Alzheimer's disease (AD) presents a significant socio-economic challenge globally, with China experiencing a notable rise in its prevalence. This study addresses critical gaps in understanding AD's economic burden and quality of life (QoL) impacts on patients and caregivers in Mainland China.
详细描述
Methods: Employing a nationwide multistage clustered sampling design. The clusters were hospitals (from 31 provinces across China), which were stratified by provincial the Alzheimer's Disease population size (based on the China Alzheimer's Disease Report 2024 and the China Statistical Yearbook 2025). Within selected hospitals, sequential samples of patients dignosed with AD and aMCI were drawn The survey, incorporating validated scales and structured interviews, will assess economic burdens, QoL, and caregiver burdens. Statistical analyses, including multiple linear regression models and random forest techniques, will examine factors associated with economic burdens and QoL.
Discussion: This research, spanning all provinces of mainland China, promises to be a timely analysis of AD's economic burden. Beyond quantifying direct and indirect costs, it integrates validated scales to understand patients' and caregivers' emotional and social dimensions. Insights gleaned will inform targeted interventions, caregiver support strategies, and evidence-based policy reforms, thereby enhancing AD care quality and resource allocation efficiency in Chinese healthcare settings. Ethical considerations and future research avenues are also outlined, emphasizing a comprehensive and forward-looking approach.
