#IHI It is not a scientific survey, but these push pins give a sense of what's working and what's not in process improvements in the health care field. The boards were posted at the IHI Annual Forum. Forum participants were asked to use red pins to indicate processes "that continue to challenge you" and green pins are the ones "for which you have demonstrated success." If you compared these year to year, you could get a sense of the general progress of process improvement in hospitals and physician practices. I include just a few examples.
