3. Delirium Demographics
Occurs in 15-60% of general patients and most frequent complication of hospitalization in older patients
Complicates 2-3 million people yearly.
Involves over 17.5 million inpatient days.
Over $4 billion in Medicare expenditures.
Development of delirium selected as one of the top three most important areas for quality of care improvement in older adults.

4. How is it detected? Arousal Assessment Attention Assessment
Ramsey Scale and Glasgow Coma Scale
Attention Assessment
Confusion Assessment Method (CAM)
Acute onset of mental changes
Inattention
Disorganized thinking
Alertness

5. Project Objectives
Develop system that can continuously measure delirium in ICU patients
Device must be small, cost-effective, comfortable, and practical
Real-Time measurements, data storage, and analysis of information (software)

6. Current Work
Researching companies for sleep detection systems on the market.
Researching body signals indicating sleep status.
Early design requirements as dictated by ICU requirements.

7. Future Work Review and evaluate preliminary findings.
Set a meeting with neurology specialist Dr. Abhou-Kahalil at VUMC.
Speak with sleep specialist Atul Malhotra at Harvard to review and evaluate the device.
