STATE OFEMERGENCY

Purpose

To identify the opportunities and

challenges for conducting IE

research in healthcare.

“Drug-resistant infections kill more Americans than AIDS and breast

cancer combined.”

$30 billion Cost of

hospital/health care associated infections.

1.7 million Patients get health

care associated infections.

hospital infections.June 19, 2006

Medical Devicesand Applications

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.

US Demographics

Americans 60 or older constituted 16.7% of the population in 2005.

This is projected to grow to 23.8% in 2030.

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)

What U.S. healthcare network is the benchmark for patient

safety and treatment?

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
