Well if we are talking about hospitals and healthcare systems, the answer would be 'none', for obvious reasons.what other species has a social construct that allows it's sick and weak to survive
If we are talking about species that protect and care for their elderly and their young, the answer would be 'a lot'. Dolphins, whales, gorilla's, elephants have all been recorded protecting their vulnerable. Birds defend their nests and hatchlings against predators.
I recently saw a video in which two adult Africa elephants rescued a baby elephant at risk of drowning in a watering hole. In the past I have seen a video in which an elephant faces off against a crocodile which had grabbed hold of a young wildebeest (I seem to remember it was a wildebeest - but am happy to be corrected) until the crocodile retreated. There are tales (unconfirmed in person but available on YouTube and general searches) of dolphins protecting humans from sharks. I also vaguely remember seeing a documentary many years ago of turtles guarding and shepherding their newborn from the beach into the sea.
I think the argument can thus be made that many species have the social constructs you refer to. Perhaps we do it better as we have more tools at our disposal.
Don't know of any instances of dolphin 'tribes' going to war with each other though.
