Adjusting Health Expenditures for Inflation: A Review of Measures for Health Services Research in the United States.
Abstract
OBJECTIVE:
To provide guidance on selecting the most appropriate price index for adjusting health expenditures or costs for inflation. DATA SOURCES:
Major price index series produced by federal statistical agencies. STUDY DESIGN:
We compare the key characteristics of each index and develop suggestions on specific indexes to use in many common situations and general guidance in others. DATA COLLECTION/EXTRACTION METHODS:
Price series and methodological documentation were downloaded from federal websites and supplemented with literature scans. PRINCIPAL FINDINGS:
The gross domestic product implicit price deflator or the overall Personal Consumption Expenditures (PCE) index is preferable to the Consumer Price Index (CPI-U) to adjust for general inflation, in most cases. The Personal Health Care (PHC) index or the PCE health-by-function index is generally preferred to adjust total medical expenditures for inflation. The CPI medical care index is preferred for the adjustment of consumer out-of-pocket expenditures for inflation. A new, experimental disease-specific Medical Care Expenditure Index is now available to adjust payments for disease treatment episodes. CONCLUSIONS:
There is no single gold standard for adjusting health expenditures for inflation. Our discussion of best practices can help researchers select the index best suited to their study. © Published 2016. This article is a U.S. Government work and is in the public domain in the USA.
