TITLE: Statistical Analysis of Longitudinal Medical Cost Data
ABSTRACT: Medical costs are on the rise during the past half centuries. Out-of-control costs are the main obstacle to securing medical coverage for all, and reducing the growth rate of health care costs is the single most important fiscal issue we face as a country. In this talk we give an introduction to the statistical analysis of longitudinal (e.g., monthly) medical costs. We review several innovative statistical models from our research efforts during the past several years. Such methods are more efficient than the analysis of cross sectional medical costs and essential to understand the dynamics of medical costs. We also show the applications of these models to analyze monthly medical costs of chronic heart failure patients from the clinical data repository (CDR) at the University of Virginia Health System.
