The SpaceX #Crew-11 Post-Splashdown News Conference https://www.youtube.com/watch?v=QFOVIAxEFng was quite interesting: nothing detailled, of course, about the astronaut health issue (at first "serious", now the person is "fine", in Isaacman's words) and while this was *not* an emergency return some such scenarios were discussed in detail. The crew stays at a hospital in San Diego over night (the only change relative to a regular off-California splash-down) before all four should continue on to Houston ... and will eventually meet the press.
