Chris Alcock and I have recently been researching the penetration of Lean or Six Sigma or Lean 6 Sigma in hospitals in the USA.
The above URL names the top 20 best hospitals in the USA, 2016, according to a detailed study undertaken by the US News magazine. (See also text attachment)
So I started from the top, seeing which ones had undertaken Lean / 6S / L6S initiatives.
1st place Hospital – yes
2nd place Hospital – yes
3rd place Hospital – yes
4th place Hospital – yes
9th place Hospital – yes
10th place Hospital – yes
19th place Hospital – yes
20th place Hospital – yes
We have the URLs of our research as evidence.
We also found evidence of the use of Lean Six Sigma ( not just Lean )…

Conclusion: Lean 6 Sigma is used by all of the best hospitals in the USA. And Virginia Mason wasn’t even in the top 20!
That is a pretty powerful body of evidence in support of Lean and Six Sigma.
