Maybe but an injury 15miles off shore in a rib in rough conditions a different story from an injury 30m from a riverbank in calm conditions.
Assume you fall over and break your leg (I'm assuming you have someone with you)... 15miles off shore you'll want to properly immobilise it before a long slow trip back ashore. Hypovolaemic shock will be a concern. Even if you are going to be airlifted off you can bank on a half hour minimum and probably more likely 60 minutes or more bouncing about in a rib I'd want to try and stabilize an injury.
In a river you can put ashore in minutes and deal with it there. You can presumably get an ambulance to you with all the kit you could imagine in less than 15minutes.
In a river you may be at less risk of needing seasickness tablets or pain killers. Much more likely you are just going to head ashore.
I'd suggest if you are river / inshore and working on that basis you will want some minor injury stuff (pain killers, plasters etc) in your car where it will be nice n dry. I'd have some superglue and some spray plaster in there.
I've never managed to get a plaster to stick on a boat. If its minor it'll be fine without, if it NEEDs a dressing stick some gauze or melolin on it followed by either a bandage or duct tape.
