2. National Student Design Competition
Sponsored by Rehabilitation Engineering Research Center on Accessible Medical Instrumentation
Problem: Increase in healthcare costs require the need for medical tasks to be moved into the home
Aim: Design an affordable, at-home vital signs monitoring system, that can transmit medical information
Specs: collect 4-6 vital signs, store/retrieve data, easy to use, accessible at home

3. Project Background
The growing number of elderly people means even more stress will be placed on emergency rooms
Currently at home vital systems or personal nurses are too expensive for everyone to use

4. Changing the Face of Healthcare
Number of hospital emergency departments cut by 14% in 2005
ER visits reached a record high of 114 million, consisting primarily of the uninsured and elderly
US 65-and-over population has risen 9.6% over that same time period

5. Why target the elderly?
ER visits by Americans age 65 and over rose 26% in 2003
Medicaid patients were four times more likely to seek treament in an ER than those with private health insurance
Nursing home residents age were five times more likely to visit the ER than non institutionalized seniors

6. Patient Challenges Must accommodate patients with varying disabilities
Blind
Deaf
Elderly
Bed ridden
Motor movement challenged
Little technology experience

7. Requirements User friendly Cost effective Visual usage Audio usage
Large responsive user interface
Compact
Aesthetically pleasing
Fast response
Telemedicine
