March 24, 2006 (Chicago) -- The number of total knee replacements performed in the U.S. will leap by 673% -- reaching 3.48 million -- by the year 2030, according to a new study presented at the 73rd annual meeting of the American Academy of Orthopaedic Surgery in Chicago.
Hip replacements will increase by 174% to 572,000 by 2030, according to the new findings, which are based on historical procedure rates from 1990 to 2003, and on population projections from the U.S. Census Bureau.

U.S. Healthcare Spending is “Booming.”
• 78 million baby boomers started turning 60 this year
• Armed with more information and “healthcare activism”
• Ads target lifestyle conditions, driving Rx• Advanced technology costs $$$ and requires
engineering (MRI, stenting, etc.) (innovator’s dilemma)

Summarizing the Sobering Stats.
• 46 million uninsured (1 in 6 Americans)
• Cost of $25+ billion/yr
• 100,000 die from medical error each year

U.S. vs. the World
• Of 25 industrialized countries– U.S. spends $6,100 per capita– Others average $2,500 per capita– U.S. is 25th in life expectancy– Healthcare is 1/6 of GNP (4x defense)– Not correlated with income
• ABC News. “U.S. Healthcare Could Learn From Rest of World.” Report aired 9/21/06.
