The S&P Healthcare Economic Indices estimate the per capita change in revenues accrued each month by hospital and professional services facilities for services provided to patients covered under traditional Medicare and commercial health insurance programs in the U.S. The annual growth rates are determined by calculating a percent change of the 12-month moving averages of the monthly index levels versus the same month of the prior year.
"The annual growth rate of Medicare and commercial insurance costs has slowed significantly in the last five months and substantially dropped in the month of October," says David M. Blitzer, Chairman of the Index Committee at Standard & Poor's. "In the 12 months ended in October, the composite index rose 6.70%, which is 1.7 percentage points less than our recorded peak of 8.40% in May 2010. Expenditures associated with commercial health insurance plans continue to significantly outpace expenditures for Medicare; the commercial increase over the 12 months to October was 8.21% vs. 4.18% for Medicare.
"We are seeing two patterns in these data. The first is the large and growing difference between commercial and Medicare annual growth rates, and the second is the across-the-board deceleration in these rates in 2010. Since May, 2010, most of the indices annual growth rates have declined month-to-month. Indeed, the slowdown in annual expenditure growth continued with this release. Comparing the 12-months-to-October with the 12-months-to-September, the Hospital Medicare Index showed the most moderation in costs, up 3.33% versus +3.96% reported for September; while the Professional Services Medicare Index showed the slightest decrease in the growth of expenditures, up 5.13% versus +5.41% in September. Both the Hospital and Professional Services Commercial Indices annual rates decelerated by about 0.3% in October."
The S&P Healthcare Economic Composite Index is a weighted average of the S&P Healthcare Economic Commercial Index and the S&P Healthcare Economic Medicare Index. Alternatively, it is a weighted average of the S&P Healthcare Economic Hospital Index and the S&P Healthcare Economic Professional Services Index, as each of these indices has the analogous Commercial and Medicare component.
