Good to see someone taking control of the situation.
Well, as on the train, I'm more than willing to train anyone interested in emergency first aid. The more people we have able to at least do something in an emergency, the better. Especially considering we have no idea how many people we're going to end up with- there's a whole island to fill, this time.
As Grey mentioned about the pharmacy- perhaps we ought to move items over to the hospital. I'm slightly concerned that, unlike on the train, when we run out of medication we run out of medication. Sherlock is a skilled chemist, and may be able to figure out something... I don't know, exactly. But worth thinking about.
