Based on claims data for 218,000 active and retired nonelderly unionized autoworkers and their dependents, the study found that health spending per enrollee in 2009 varied widely across 19 communities with large concentrations of autoworkers, from a low of $4,500 in Buffalo, N.Y., to a high of $9,000 in Lake County, Ill. The autoworkers’ health benefits are essentially uniform nationally, so spending differences do not reflect benefit differences.
Differences in service quantities accounted for two-thirds of the overall spending variation, while differences in prices accounted for one-third, according to the study.
On the quantity side, differences in health status and other demographic factors explained most, but not all, of the variation in quantity. About 18 percent of the total variation in spending was a result of unexplained differences in service quantities. On the price side, the cost of doing business explained very little of the price differences, with almost all of the differences in prices unexplained, the study found.
“The study documents that differences in prices—especially for hospital care—play a significant role in regional spending variation for privately insured people,” said study author Chapin White, Ph.D., an HSC senior researcher.
“At the same time, the finding that almost a fifth of the total variation in spending across the communities is a result of unexplained differences in quantities suggests there is significant room to improve care delivery and increase efficiency,” White said.
The study’s findings are detailed in a new NIHCR Research Brief—Health Status and Hospital Prices Key to Regional Variation in Private Health Care Spending—available online at www.nihcr.org.
To compare prices paid by the autoworker plan with Medicare prices, three categories of services were examined: physician office visits for evaluation and management services, hospital facility fees for inpatient care, and hospital facility fees for emergency department care.
The study also included spending information from the following metropolitan areas: Akron, Ohio; Cleveland; Detroit; Flint, Mich.; Grand Rapids, Mich.; Kokomo, Ind.; Lansing, Mich.; Monroe, Mich.; Rockford, Ill.; Saginaw, Mich.; Toledo, Ohio; Warren, Mich.; Wilmington, Del.; and Youngstown, Ohio.
The National Institute for Health Care Reform contracts with the Washington, D.C.-based Center for Studying Health System Change to conduct high-quality, objective research and policy analyses of the organization, financing and delivery of health care in the United States. The nonpartisan, nonprofit 501 (c)(3)organization was created by the International Union, UAW; Chrysler Group LLC; Ford Motor Company; and General Motors to help inform policy makers and other decision-makers about options to expand access to high-quality, affordable health care to all Americans.
The Center for Studying Health System Change is a nonpartisan policy research organization committed to providing objective and timely research on the nations changing health system to help inform policy makers and contribute to better health care policy.
