STUDY: STATES WITH HIGHER MEDICARE SPENDING
OFFER LOWER-QUALITY CARE
Of Primary Care Doctors Yield
More Effective Care And Lower Spending
Bethesda, MD — States with higher Medicare spending often provide lower-quality, less-effective care to Medicare beneficiaries, according to a new study released today in the journal Health Affairs. For policymakers, the study shows that spending more money does not necessarily translate into better quality of care for the elderly.
States spending more money
per Medicare beneficiary are likely spending those dollars on intensive, expensive
care instead of more effective care. In addition, high-spending states are likely
to have a greater concentration of specialists, according to the study’s
The study, which examined state-level differences in spending per Medicare beneficiary and the quality of care provided, found that higher spending did not translate into higher quality. For example, New Hampshire, which spent about $5,000 per Medicare beneficiary in 2001, had the highest overall quality ranking, while Louisiana, which spent the most per Medicare beneficiary at $8,000 per person, had the lowest overall quality ranking.
“Health care leaders should not make the mistake of thinking that we can only improve the quality of health care delivered to elderly Americans by spending more money,” says lead author Katherine Baicker, Ph.D., assistant professor in the Department of Economics at Dartmouth. “Instead, we could simply use existing dollars much more effectively.”
Baicker and her colleague, Amitabh Chandra, Ph.D., point out that higher spending is unlikely to cause lower-quality care but rather is an indicator of a particular style of health care provision and resources. In fact, the composition of the physician workforce — the mix of specialists and general practice physicians in a given area — plays a critical role in determining the use of highly effective care.
The study found that states with relatively more general practitioners show greater use of high-quality care and lower spending per beneficiary. Increasing the presence of general practitioners in a state by 1 per 10,000 people is associated with a rise in the state’s quality ranking and a reduction in overall spending of $684 per beneficiary. Conversely, increasing the presence of specialists by 1 per 10,000 people leads to a drop in overall quality and an increase in spending of $526 per beneficiary.
Among the study’s findings:
• States with lower
spending often had better-quality care — such as higher use of interventions
and screening methods, including prescribing beta-blockers at hospital discharge
for patients treated for a heart attack, ordering mammograms every two years
for women ages 65-69, and conducting regular hemoglobin tests and biennial eye
exams for people with diabetes
• States with higher spending and lower-quality care had more frequent hospitalizations and use of intensive care units (ICUs) for patients in the last six months of life
• Medicare patients in states that spent $1,000 more per beneficiary spent an average of 1.3 more days in the hospital and were 3.9 percent more likely to be admitted to an ICU
The researchers based their analysis on twenty-four quality measures developed by the Medicare Quality Improvement Organization (QIO), as well as data from the Dartmouth Atlas of Health Care on the number of days Medicare beneficiaries in their last six months of life spent in a hospital and what fraction of them are admitted to the ICU.
Cutting Spending Not The Answer To Improving Care For Medicare Beneficiaries
While the study finds a link between higher spending and lower-quality care, the researchers emphasize that cutting Medicare spending as a way to improve quality could have the undesirable effect of reducing the quality of medical care in high-spending states even more.
Instead, the authors suggest concentrating on policies that improve the quality of care for beneficiaries, such as establishing national practice benchmarks for basic quality measures and encouraging greater access to general practitioners.
“Improving quality of care has everything to do with how the money is spent,” says coauthor Chandra. “And there is good evidence that, in many cases, we are not spending it wisely now. We need to determine how to make better use of health care dollars, especially with the baby-boom generation about to enter the Medicare system in the next few years.”
