Feasible methods to estimate disease based price indexes

Area of Science:

• Health Economics
• Medical Data Analysis
• Statistical Modeling

Background:

• Consensus exists for reporting medical data by disease, not service.
• Traditional medical price indexes may not reflect treatment efficiency gains.
• Accurate deflation of nominal disease expenditures is crucial for economic analysis.

Purpose of the Study:

• To compute feasible disease-based price indexes for deflating medical expenditures.
• To decompose medical expenditure growth into price, prevalence, and efficiency components.
• To implement methods adaptable by the Bureau of Labor Statistics (BLS).

Main Methods:

• Calculation of disease-based price indexes using novel methodologies.
• Decomposition analysis of nominal disease expenditure growth.
• Comparison of newly computed indexes with current BLS methods.

Main Results:

• Disease-based price indexes were computed for 2005-2010.
• These indexes were approximately 1% lower annually than BLS-computed indexes.
• Findings suggest traditional indexes overestimate medical price inflation.

Conclusions:

• Feasible disease-based price indexes provide a more accurate measure of medical cost changes.
• Current medical price indexes may not fully capture efficiencies in disease treatment.
• Adoption of disease-based reporting can improve economic assessments of healthcare.
