Yes, to answer your question directly.
It can really matter to a hospital if you get burn training during GS residency (three or four blocks of burn training are offered by all Texas GS residencies), but there are many accredited burn inclusive trauma and surgical critical care fellowships. Almost all the larger tertiary facilities require board certification in Trauma/SCC along with a lot of burn training. I would suggest that integrated PRS residencies do not include enough burn training for ED work.
