Career Development Plan and Institutional Resources Summary. The career development plan consists of five years of focused instruction in epidemiology and health services research. Through a combination of course work and individual tutorials, enhanced research skills will be developed in three core areas: health economics and cost analysis; advanced methods in statistical modeling; and introduction to the use of administrative and national survey data. These new skills will provide a foundation for an independent research career in dementia, health services research focused on determinants of health care utilization, costs and response to interventions in naturally occurring populations. Michigan State University has a strong tradition in both epidemiology and health serviceS research. This environment will provide frequent opportunities for interaction will colleagues with similar research interests for career guidance, critique of ongoing research, and development of new research ideas. Research Plan Summary. Alzheimer's disease (AD) imposes a great economic burden on patients, their families and society. New treatments for AD are being developed to modify clinical features of the disease, but the relationships between these clinical features and direct health care costs are not known. We will build a data set for investigating determinants of direct heath care costs in an AD population. The Behavioral Model of Health Services Use will provide a conceptual framework for data collection and analysis. We will measure direct health care costs in a well-characterized cohort of 300 probable AD patients over four years, by repeated survey measurements and linkage to HCFA administrative data. We will examine the relationships between direct costs and six "need" factors hypothesized to be important determinants of direct, health care costs in AD. These six "need" factors (ie, severity of the AD patient's cognitive, psychiatric, and motor impairment, co-morbid medical conditions, "dependency" and caregiver "perceived burden") will be measured with validated, clinical measurement instruments. We will use multiple regression analysis techniques, including path analysis, structural equation modeling, and general longitudinal modeling to test study hypotheses. This project will develop explanatory and predictive statistical models of direct health care costs in AD patients, that can help focus and evaluate future interventions in this disease.

职业发展计划和机构资源摘要。职业发展计划包括为期五年的流行病学和卫生服务研究的重点指导。通过课程工作和个人辅导相结合，将在三个核心领域加强研究技能：保健经济学和成本分析；统计建模的先进方法；行政和国家调查数据的使用入门。这些新技能将为痴呆症的独立研究生涯奠定基础，这是一项专注于自然发生人口中卫生保健利用、成本和干预措施的决定因素的卫生服务研究。密歇根州立大学在流行病学和卫生服务研究方面都有着深厚的传统。这种环境将为具有相似研究兴趣的同事提供频繁的互动机会，以进行职业指导、批评正在进行的研究和开发新的研究想法。研究计划摘要。阿尔茨海默病(AD)给患者及其家庭和社会带来了巨大的经济负担。人们正在开发治疗阿尔茨海默病的新疗法，以改变该病的临床特征，但这些临床特征与直接医疗费用之间的关系尚不清楚。我们将建立一个数据集，用于研究AD人群中直接医疗保健费用的决定因素。《卫生服务使用行为模型》将为数据收集和分析提供一个概念性框架。我们将通过重复调查测量和与HCFA管理数据的联系，在四年内对300名疑似AD患者的特征良好的队列中的直接医疗费用进行衡量。我们将研究直接成本和6个“需要”因素之间的关系，这些因素被认为是AD患者直接医疗成本的重要决定因素。这六个“需要”因素(即阿尔茨海默病患者认知、精神和运动障碍的严重程度、共病的医疗条件、“依赖性”和照顾者的“感知负担”)将通过有效的临床测量工具进行测量。我们将使用多元回归分析技术，包括路径分析、结构方程建模和一般纵向建模来检验研究假设。该项目将开发AD患者直接卫生保健费用的解释性和预测性统计模型，有助于集中和评估未来对该疾病的干预措施。
