National health expenditure accounts: Meaning, Criticisms & Real-World Uses

What Are National Health Expenditure Accounts?

National Health Expenditure Accounts (NHEA) are the official set of statistics that measure the total annual spending on healthcare in the United States. These accounts offer a comprehensive overview of the nation's healthcare system by tracking expenditures for various medical goods and services, as well as the sources of funding for that care. As a crucial component within healthcare economics, the NHEA provide insights into financial flows across the entire sector, from patient out-of-pocket costs to government programs and private insurance.

The National Health Expenditure Accounts are designed to be comprehensive, multidimensional, and consistent, facilitating comparisons among different spending categories and over time⁴⁵, ⁴⁶. They are generally compatible with broader economic indicators like the National Income and Product Accounts (NIPA), but offer a more detailed picture specifically focused on health-related expenditures⁴⁴.

History and Origin

The U.S. Department of Health and Human Services (HHS), through its Centers for Medicare & Medicaid Services (CMS), has been publishing annual data on total national health expenditures since 1964⁴², ⁴³. These estimates, later formalized as the National Health Expenditure Accounts, aimed to measure the total annual dollar amount of healthcare consumption in the U.S., alongside investments in medical infrastructure and non-commercial research⁴¹. The methodology for compiling the NHEA has continuously evolved, with CMS (formerly the Health Care Financing Administration, HCFA) engaging in ongoing efforts to improve data collection and reporting processes. Conferences have been periodically convened, for instance in 1984, 1990, 1998, and 2005, to discuss recommendations for methodological changes, data dissemination strategies, and future extensions of the NHEA projects, reflecting a commitment to enhancing the accuracy and utility of these vital statistics⁴⁰.

Key Takeaways

National Health Expenditure Accounts (NHEA) are the official measure of total healthcare spending in the U.S., compiled by the Centers for Medicare & Medicaid Services (CMS).
They track expenditures by type of service (e.g., hospital care, prescription drugs) and by source of funds (e.g., private insurance, Medicare, Medicaid).
NHEA data date back to 1960 and are essential for understanding historical trends and projecting future healthcare costs.
The accounts are used by policymakers, researchers, and stakeholders to analyze the economic performance of the healthcare sector and inform public policy decisions.
In 2023, U.S. healthcare spending reached approximately $4.9 trillion, representing 17.6% of the nation's Gross Domestic Product (GDP).³⁸, ³⁹

Interpreting the National Health Expenditure Accounts

Interpreting the National Health Expenditure Accounts involves understanding not just the raw dollar figures, but also their context relative to the broader economy and demographic shifts. The NHEA data are presented by type of service, sources of funding, and type of sponsor (e.g., businesses, households, government spending)³⁶, ³⁷. This multidimensional breakdown allows for granular analysis, such as identifying shifts in the mix of medical services consumed or changes in how care is financed³⁵.

For example, observing the percentage of GDP devoted to healthcare provides a macroeconomic perspective on the sector's scale relative to the overall economy³⁴. Changes in this percentage can indicate whether healthcare spending is growing faster or slower than the rest of the economy. An increase often reflects factors such as rising prices for medical goods and services, increased utilization, or new medical technologies. Conversely, a decline might suggest economic recovery outpacing healthcare growth or policy changes impacting spending³², ³³. The NHEA also track expenditures by payer, such as the growth rates of spending from private health insurance versus government programs, which can highlight financial pressures and the impact of changes in healthcare costs on different segments of the economy³¹.

Hypothetical Example

Consider a hypothetical nation, "Healthland," that implements a new national health initiative aimed at reducing chronic disease through preventative care. Before the initiative, Healthland's National Health Expenditure Accounts showed total healthcare spending of $500 billion. Of this, 60% ($300 billion) was attributed to treatment of chronic diseases, 20% ($100 billion) to acute care, and 20% ($100 billion) to preventative services.

After five years, the updated National Health Expenditure Accounts for Healthland reveal a total healthcare spending of $550 billion, an increase influenced by inflation and population growth. However, a closer look at the breakdown shows a shift: chronic disease treatment now accounts for 50% ($275 billion), acute care remains at 20% ($110 billion), and preventative services have increased to 30% ($165 billion). This hypothetical scenario demonstrates how changes in the composition of spending within the National Health Expenditure Accounts can indicate the success or impact of specific health interventions or public policy decisions, even if overall spending has increased. Analysts would use these figures to evaluate the initiative's effectiveness in reallocating resources towards preventative care.

Practical Applications

The National Health Expenditure Accounts (NHEA) are a foundational data set with wide-ranging practical applications in various economic and policy arenas. These accounts provide detailed information critical for data analysis and decision-making for a diverse set of stakeholders.

Policy Formulation: Policymakers rely on NHEA to understand spending trends and project future healthcare costs, which is essential for developing and evaluating legislation related to healthcare reform, government spending on health programs, and resource allocation within the public sector. The Centers for Medicare & Medicaid Services (CMS) actively uses this data for forecasting and policy analysis.³⁰
Economic Analysis: Economists and researchers use NHEA data to study the healthcare sector's contribution to and impact on the overall economy, including its share of the Gross Domestic Product (GDP) and its influence on economic growth. For instance, the Peterson-KFF Health System Tracker frequently utilizes NHEA data to illustrate how U.S. healthcare spending has changed over time, both in absolute terms and as a percentage of GDP.²⁹
Market Research and Investment: Businesses in the healthcare industry, from pharmaceutical companies to hospital systems, use NHEA to identify growth areas, understand market dynamics, and inform investment strategies.
Healthcare Financial Planning: Individuals and organizations can utilize NHEA insights to understand broader trends in healthcare costs, which can inform personal financial planning, employer benefits design, and risk assessments for insurance providers.
International Comparisons: The consistent methodology of the NHEA, while domestically focused, often serves as a basis for comparative studies with other nations' healthcare spending data, helping to benchmark the U.S. system against global peers. The CDC offers an overview of the NHEA, highlighting its use in measuring aggregate healthcare expenditures and facilitating comparisons over time.²⁸

Limitations and Criticisms

While National Health Expenditure Accounts (NHEA) are invaluable for understanding healthcare spending, they do have limitations and have faced criticisms regarding their scope and methodology. One common area of discussion revolves around the challenge of harmonizing the U.S. NHEA with international standards, such as the System of Health Accounts (SHA), which often employ a "functional approach" to classify expenditures. This can lead to differences in how certain types of spending are categorized; for example, the NHEA might classify drugs used in hospitals as hospital spending, while a functional approach would classify them as drug spending, making direct cross-country comparisons complex without careful reconciliation.²⁷

Another point of consideration is the level of detail regarding the "value" derived from the spending. The NHEA primarily focus on expenditures, measuring the total annual dollar amount of healthcare consumption²⁶. They do not inherently measure the quality of care received, health outcomes, or the efficiency with which resources are utilized. Therefore, a higher expenditure figure does not automatically equate to better health or a more effective healthcare system. Critics suggest that solely focusing on spending without corresponding outcome metrics can paint an incomplete picture of the overall health economy.

Furthermore, the compilation of NHEA data involves drawing from a wide array of government and private sector sources, including various surveys, administrative data, and economic census information²⁵. While CMS strives for consistency and accuracy, the inherent complexity and potential for lags in data availability or revisions can sometimes lead to adjustments in historical figures, which can impact multi-year trend analysis²⁴. These comprehensive revisions, undertaken periodically, incorporate new source data and methodological updates, ensuring the accounts remain relevant but also necessitating an understanding that past figures can be updated²³.

National Health Expenditure Accounts vs. Gross Domestic Product (GDP)

National Health Expenditure Accounts (NHEA) and Gross Domestic Product (GDP) are both significant macroeconomic measures, but they serve distinct purposes and capture different aspects of economic activity. The fundamental difference lies in their scope:
