Lessons learned from international emergency medicine development.

The lessons learned from development of EM around the world span several key areas including general development, systems comparisons, models of EM practice, and education and training. Neither definitive nor exhaustive, these lessons learned are intended to be viewed as sign posts along the road traveled at this point in international EM development. It is hoped that future participants in international EM development can assimilate these lessons learned, adopt the most relevant ones, and add their own insight and wisdom to this growing list. Most importantly, it is hoped that by whichever path future development takes, we all reach the same destination of providing the best possible emergency medical care for the people of the world.
