Agenda
• Provide a brief view into Biomedicine
• Look at economics
• Look at trends
• Look at engineering practice
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.
100,000 Annual deaths from
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.
Veterinary Applications
Kentucky Derby winner Barbaro suffers a fractured leg and develops a serious infection after surgery with implanted plate and screws.
Fractured leg
Implants that spawned infection
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
