I just came across a wonderful 5-minute video about lean six-sigma that Mark Graban mentioned in his blog–one of my favorites– about Lean Hospitals (see our Links We Like on the right side). The video is narrated by Brian Hudson, a researcher at Franciscan St. Elizabeth Hospital. 
Hudson was trying to improve the time it takes to get a patient with chest pain from “door” (arrival at the hospital) to “balloon” (insertion of a tube to unblock a clogged artery) down from 114 minutes to the national standard of 90 minutes. A faster “door to balloon ” time often is the difference between life and death for a heart attack patient.
A year after Hudson started his research in 2007, using lean 6-sigma, he had been able to get his hospital’s average to 74 minutes. In 2009, Hudson suffered a heart attack, watching the clock in the emergency room the whole time with the same mental checklist he had developed for doctors. If you don’t show this video in class, watch it yourself–it may save your life!
