Information is everywhere in medicine
Computerizing health care is difficult because of its complexity
Health IT has a role because “To Err Is Human”
Health IT is just a tool. Whether it improves patient care and outcomes depends on its design and implementation

Health IT Successes & Failures
What success is Different ideas and definitions of success Need more understanding of different stakeholder views & more longitudinal and qualitative studies of failure
What makes it so hard Communication, Workflow, & Quality Difficulties of communicating across different groups makes it harder to identify requirements and understand workflow

Reasons for User Involvement
Better understanding of needs & requirements Leveraging user expertise about their tasks & how organization functions
Assess importance of specific features for prioritization
Users better understand project, develop realistic expectations
Venues for negotiation, conflict resolution

Health IT applications vary in their “mechanisms of actions” (improvements in outcomes).
Health IT can lead to “unintended consequences” and bad outcomes if poorly designed, implemented, or managed.
Realizing benefits of health IT depends on critical success factors, mostly management aspects (including change management, project management)
