Failure to Thrive (FTT) is not just for the clinics. We need to be on the lookout, because if we find it, there is already a big problem.
Definitions of Failure to Thrive may quibble on the details, but for us in the ED:
We can get around the longitudinal requirement by looking at weight as a "spot check" -- if grossly below weight without any other chronic condition, be alarmed.
Failure to thrive results from inadequate calories. This may be due to:
Any concern should trigger a more complete H&P (in audio).
Classic instructional video on the mother-infant dyad (scan through for various types).
After a focused H&P, you may need to admit the child for further workup, or to show that he can/cannot gain weight with routine care.
Remember, if you are the first one to bring this up, there is a real problem. By definition, an outpatient plan has failed. We will not be able to distinguish among the various possibilities of organic and non-organic causes (or mix thereof); our job is to be ready to catch it and act on it. The child's development, future intelligence, and welfare are at risk.

No one ever wants to find himself in this situation. A factory explodes. A building catches fire. A multi-vehicle traffic collision. Or an act of terrorism.
Very quickly, we have to scrap business as usual. We have to adapt to our new circumstances.
Definition of a mass casualty incident (MCI):
An incident which produces multiple casualties such that emergency services, medical personnel and referral systems within the normal catchment area cannot provide adequate and timely response and care without unacceptable mortality and/or morbidity.
In other words, our demand far outpaces our resources.
"If you can hear the sound of my voice, follow me". Those patients are GREEN, minor.
Otherwise, we need a system to distinguish those who can be DELAYED, IMMEDIATE, or EXPECTANT (soon to be deceased).
Use Simple Triage and Rapid Treatment (START) for 8 or older, JumpSTART for less than 8 years of age.
For Older Children, Adolescents, and Adults (8 or greater) -- START:
For Children less than 8 years of age (Infants Use Pediatric Assessment Triangle) -- JumpSTART:
