Selecting the Optimal Price Index for Health Expenditure Analysis

Choosing the correct price index is crucial for accurately analyzing trends in health expenditures and ensuring the validity of research findings.

Health Services Research · 2016

01

Key Findings

  • 01The GDP implicit price deflator or overall PCE index are generally preferred over CPI-U for general inflation adjustments.
  • 02The Personal Health Care (PHC) index or PCE health-by-function index are preferred for adjusting total medical expenditures.
  • 03The CPI medical care index is best for adjusting consumer out-of-pocket expenditures.
  • 04An experimental disease-specific Medical Care Expenditure Index is available for disease treatment episode payments.
02

Application

Design takeaway

Always critically evaluate and select the most appropriate price index for your specific health expenditure analysis, rather than defaulting to a single, general-purpose index.

How to apply

When conducting research involving health expenditure data, consult this guidance to select the most accurate price index for your specific research question and data type.

Project actions

  • 01Clearly state which price index you used and why.
  • 02Consider the specific type of expenditure you are analyzing (e.g., overall spending, out-of-pocket costs, disease-specific costs) when choosing your index.
03

Method & Evidence

AimWhat are the most appropriate price indices for adjusting various types of health expenditures for inflation in the United States?
MethodComparative analysis and literature review
ProcedureThe study compared key characteristics of major federal price index series and provided recommendations for selecting specific indices based on common research scenarios in health services research.
ContextHealth Services Research, United States

Variables

IVType of health expenditure (e.g., total medical, out-of-pocket, disease-specific)
DVAccuracy of inflation adjustment
CVFederal statistical agency data sources, methodological documentation
04

Strengths & Limitations

Strengths

  • +Provides clear, actionable guidance for researchers.
  • +Compares multiple relevant price indices.

Limitations

The recommended indices might not be available or appropriate for all countries or for very niche types of health expenditures.

Reliability & validity

The reliability of the findings depends on the consistency and accuracy of the federal statistical agencies' data. Validity is enhanced by the comparative approach and the focus on specific expenditure types.

Think critically

How might the choice of price index influence the perceived success or failure of a new healthcare policy or intervention?

05

Design Principles

"The principle of specificity in economic data analysis: the tool (price index) must match the object of analysis (specific expenditure type)."

Accurate inflation adjustment is fundamental for understanding the real growth or decline of healthcare spending, informing policy decisions, and evaluating the effectiveness of interventions. Misapplication of price indices can lead to misleading conclusions about resource allocation and economic trends within the health sector.

06

What This Means for Your Design

When you look at how much money is spent on healthcare over time, you need to account for inflation. This study explains which tools (like different price indexes) are best for measuring inflation for different kinds of healthcare costs.

Paragraph starter

In this design project, the analysis of health expenditure trends required careful consideration of inflation adjustment. Following the guidance provided by Dunn et al. (2016), the [Specific Price Index Used] was selected for adjusting [Specific Expenditure Type] due to its suitability for [Reason for Selection], as opposed to more general indices like the CPI-U or GDP deflator which are less precise for this specific context.
