Bright ideas spread organically across the VA

Bad ideas wither on the vine

Example: cascading abnormal results (K+=5.9 mmol.l-1)

What happens if an NHS hospital wants to change IT supplier?

Now If NHS used VistAKeep hospital running 24 hours a day Select new supplier on basis of cost and

quality

Train staff on new system Nothing else changes

Install new system in parallel

In the existing supplier’s best interest to make transition as awkward as possible

Stagnation and uncompetitive healthcare IT market

VA spends proportionately more on IT than the private health care sector

Higher IT adoption Better quality of care

Net return on investment was $3.09 billion

Key Benefits of VistA

economies of scale) Evidence-based Darwinian improvements Stimulates competition in IT support Popular with staff (written by doctors)
