Triage by definition means that resources are too limited to handle the extent of the disease being presented. It is always a difficult and stressful situation for the healthcare provider who sometimes must allow some to die so that others might live. Practicing in the developing world, with its much more severe limitations, often changes the application of triage principles in a way which increases stress. Principles of triage in the developed world will be reviewed and practical examples from the developing world will be worked out in a group setting. Participants are encouraged to help mission hospitals develop appropriate plans for handling mass casualty and the numbers of other people that will flock to the hospital.
