The rapid growth in health care expenditures has raised difficult questions.

How do health expenditures translate into improvements in health?
What are the costs and benefits of treatments to society as a whole?

The type of information needed to address these questions is not readily available.
For example,
Nominal expenditures broken down by disease to assess the benefit of treatment
Price measures that accurately reflect increases in the quality of treatments
4www.bea.gov
BEA plans to develop a Health Satellite Account to respond to these needs.
The satellite account will provide: A reconciliation of health care spending estimates from
the Centers for Medicare and Medicaid Services (CMS) and those from the Bureau of Economic Analysis,
Data on nominal expenditures by disease that are consistent with CMS’s National Health Expenditures Accounts,
Improved price deflators, and Measures for the indirect costs of illness, such as
mortality costs and morbidity costs due to absenteeism.

Price indexes: Increasing prices are an important driver of cost increases
PCE for medical care grew 9 % per year from 1980-2005.
Over ½ of that growth represents increases in prices, as measured in standard price indexes.
Decomposition of PCE Expenditures on Medical Care, 1980-2005
Population Growth, 1.1%
Inflation, 5.1%
Real PCE, 2.6%

But existing price indexes have well-known problems.

BEA BLS MCPI
Sensitive to underlying assumptions:
BLS’ Medical Care Price Index (MCPI) focuses on consumer payments
BEA price index relies on indexes from the BLS PPI program
Both have problems accounting for
quality improvements, and reduced cost of treatment
7www.bea.gov
BEA’s satellite account will include a disease-based price index.
Disease-based price indexes will better account for reductions in cost that arise from the substitution across treatment classes.
These episode-based indexes will be used to construct indexes for expenditures by product class and by industry, as currently reported in the accounts.
The index will not address the problem of accounting for improvements in treatments.
Difficult problem where there is no consensus on the solution.
8www.bea.gov
Preliminary work on price indexes suggests the issue may be numerically important.

Progress and PlansTwo-year effort to study data sources and methods
Completed preliminary draft of study on disease-based price indexes.
Continued interaction with members of the academic and statistical communities
Participating in National Academies Panel on Health Accounts Working closely with David Cutler and Allison Rosen’s Health
Accounts Group Maintaining contact with colleagues at CMS, BLS, and other
statistical agencies.
Plan is to develop a detailed proposal for a BEA Health Satellite Account by the end of 2009.
