IOM Report: Health IT and Patient Safety
Problem
- Poorly designed health IT can create new hazards in the already complex delivery of care.
- Dosing errors, failure to detect life-threatening illnesses & delaying treatment due to poor HCI or loss of data have led to serious injury & death.
Recommendations:
- User-centered design & human factors applied to health IT
