State Offices of Minority Health and health and public health departments employ a variety of approaches to document racial and ethnic health disparities to help advance health equity. In the current fiscal climate, states continue to face budget deficits, and as a result, they are increasingly focusing on identifying and reducing costs, including those associated with health disparities. The U.S. Department of Health and Human Services’ Office of Minority Health defines these as "health differences...closely linked with social or economic disadvantage."1
This issue brief describes state2 efforts to quantify the human and financial costs associated with racial and ethnic disparities in health status and health care. It highlights how states measure these costs, some of the challenges states may encounter in doing so, potential strategies to address these challenges, and new state publications in Rhode Island and Virginia about the costs of disparities. Finally, this issue brief offers several tools and resources for those interested in further learning on this topic.
A recent Agency for Healthcare Research and Quality (AHRQ) report authored by the National Academy for State Health Policy (NASHP) summarizes lessons from several states’ experiences in documenting racial and ethnic disparities in health and health care, and also subsequently using the documents to inform and spur improvement efforts.3 Based on review of state publications and conversations with publication authors, this issue brief focuses and expands on one topic raised in the AHRQ report: states’ increased interest in analyzing and documenting the impact of disparities.
National research demonstrates the potential value of such an approach by states. The Joint Center for Political and Economic Studies estimates racial and ethnic disparities to have cost this nation $1.24 trillion between 2003 and 2006: $229.4 billion for direct medical care expenditures associated with health disparities and another $1 trillion for the indirect costs of disparities.4 Among the findings in the recent CDC Health Disparities and Inequalities Report is that, if non-Hispanic Blacks had had the same adjusted rate of preventable hospitalizations as non-Hispanic Whites from 2004 to 2007, it would have resulted in about 430,000 fewer hospitalizations for non-Hispanic Blacks and $3.4 billion in savings.5
According to officials from states included in the AHRQ report, understanding and documenting information about the costs of disparities are important for several reasons:
States' Approaches to Measuring Costs
States in the AHRQ report calculate costs of disparities in three ways: in financial terms of excess health care utilization and expense (e.g., excess hospitalization); in terms of excess deaths or human life lost; and in terms of lost productivity (i.e., days of work).
Measurement challenges and lessons
Through their experiences analyzing and publishing cost of disparities data using the above approaches, featured states have encountered a few challenges, devised strategies to cope with them, and learned helpful lessons about measurement.
First, the size of the minority population can influence the confidence of estimated calculations. The data may be unreliable for states in which the number or percentage of people who are members of racial and ethnic minority groups is small, or in populations for which there is insufficient data. One approach states take to cope with small numbers is to aggregate data over several years to increase sample size.
In addition, it is not uncommon for states to see high numbers of hospital admissions where the patient’s race/ethnicity is either unknown or undocumented. For these reasons, states often choose measures generated from less suspect race/ethnicity data such as excess death to describe Black mortality in relation to White mortality. States also consistently work in tandem with hospital associations and communities to improve the collection of race/ethnicity data by implementing or reinforcing collection standards and increasing community awareness of the value of self-reporting race/ethnicity information to health care providers.
Finally, in its data chart book, Maryland emphasizes the distinction between disparities in the frequency of hospital admission and disparities in the severity of admission (e.g., length of hospital stay), which carry quality of care and cost implications.9 The approach to calculating excess health care expenses described above always captures the excess cost due to higher minority admission frequency. If the excess number of minority admissions is multiplied by the average cost of minority admissions, then the method will also capture the excess cost due to higher severity within the excess admissions. An additional computation is needed to capture the cost of higher minority severity within the non-excess minority admissions: the non-excess minority admission count must be multiplied by the difference between average minority and average White costs per admission. Maryland will pursue the severity concept in future reports and analyses.
Profiles of Two State Approaches
Rhode Island and Virginia, two states referenced in the aforementioned AHRQ report on documentation of racial and ethnic health disparities to inform strategic action, have undertaken new reports that include a greater emphasis on the costs of disparities in health and health care. This section provides information about these states’ innovative publications, which can serve as examples for other states interested in compiling and disseminating similar data for policymakers and the public.
Rhode Island is preparing to publish Series on the Cost of Health Disparities in Rhode Island - A Focus on Health Determinants, Life Course, and Equity. In this document, the state explores excess morbidity, mortality, and unnecessary hospitalization for several conditions, including HIV/AIDS, diabetes, cardiovascular disease, sexually transmitted diseases (particularly chlamydia, gonorrhea, and infectious syphilis), and overweight/obesity. The report presents these data by population: minority group, place (core city or non-core-city), gender, age, insurance, and education/income. Rhode Island underscores the importance of "place" in addition to population, noting that health problems, poor outcomes and lack of access to care often are determined by location as much as by race/ethnicity or insurance status.
The cost report is intended for the general public. However, state officials hope that, in particular, policymakers responsible for allocating resources will find the report to be useful and informative. This is the state’s first foray into reporting exclusively on the costs of health disparities, but state officials plan to continue building on the report as new data resources are developed, such as an all-payer claims database. The state aims to update the report every few years; related future plans include analysis of healthy days and lost productivity at work.
Virginia will soon release the 2011 Health Equity Report, an update to a 2008 report.10 The 2008 report included some financial and human cost estimates, specifically hospital discharge costs by zip code and YPLL. After determining that costs are an issue of great public interest, Virginia has included a greater focus on the topic in the updated report, which will be published in the summer of 2011.
For the 2011 report, Virginia has contracted with the Department of Economics at Virginia Polytechnic Institute and State University (Virginia Tech) for detailed cost estimates. The updated report includes several comparisons; among these are African-Americans to Whites, urban to rural, and different levels of education. The state Office of Minority Health and Health Equity (OMHHE) is examining excess costs for different outcomes as well as several conditions, including heart disease, cancer, unintentional injuries, and low birth weight. To determine costs in the new report, the state OMHHE calculates three different measures: medical costs for hospital discharges, morbidity costs, and costs of premature mortality. Financial costs are staggering, according to the findings. For example, health disparities cost the capital city of Richmond several million dollars in one year.
For state officials in Virginia, the most useful way to illustrate human costs of disparities is in terms of life expectancy, as this measure is most familiar to the general public. Virginia has found it most powerful and most easily understood to say that a neighborhood has an average life expectancy of X years against the state average of Z years. Like Rhode Island, Virginia includes a spatial analysis of cost, which OMHHE hopes will make the 2011 report even more appealing to local policy makers
General lessons from these two states include:
Tools & Resources for States
In addition to documents previously cited in this issue brief, existing state and federal resources may prove beneficial to state policymakers interested in analyzing and documenting the costs of health disparities. Methods used and information presented in these resources may inform disparities reduction and cost containment activities in additional states.
As reports from states such as Rhode Island and Virginia demonstrate, quantifying and disseminating information about the financial and human costs associated with health and health care disparities can be an effective method of calling attention to the dramatic impact of these disparities. It can help states begin to target resources most efficiently and effectively to improve the value of care, engage and involve stakeholders in issues of minority and multicultural health, and assess state progress in achieving health equity. Although there are measurement challenges associated with small sample sizes and missing data, states continue to improve methods of making this information available to the public and to policymakers. Lessons from these states and information from their disparities reports can serve as resources to other states seeking to rein in health care spending and meet the health needs of diverse populations.
