Abstract #97056

Concentration of Health Care Expenditures: Predicting Next Year’s Tail

Given the high concentration of health care expenditures in a given year among a relatively small percentage of the population, a prediction model that can accurately identify the persistence of high levels of expenditures is an important analytical tool. This type of modeling effort also enhances the ability to discern the causes of high health care expenses and the characteristics of the individuals who incur them. This feature also applies to prediction models that can accurately identify those individuals with persistently low or average levels of expenditures. The models that are presented have particular relevance as statistical tools to facilitate efficient sampling strategies that permit the selection of an over-sample of individuals likely to incur high levels of medical expenditures in the future. Furthermore, such modeling efforts are particularly attractive to assist in the targeting of disease management programs to high cost cases, which may facilitate reductions in the concentration of overall future year health care expenditures. The national Medical Expenditure Panel Survey (MEPS), sponsored by the Agency for Healthcare Research and Quality (AHRQ), is particularly well suited for supporting modeling efforts of this nature. In this paper, the performance of alternative prediction models to identify future high expenditure cases is evaluated. Particular attention is given to investigating the added value of an extended longitudinal profile in accurately predicting future health care expenditures.
