I don't blame you for wanting to see the law or reg, truthfully I've not seen the reg either, but it basically ends up being that all active duty are required to have an ER doc sign off on all refusals and if the doc determines they want to see them, then it becomes an order for them to report to the ER. If they go with the MPs or DoD cop whoever is the one to show up on the call they are in custody until they get to the ER and the doc sees the patient and pretty much sees what we were seeing on the call. I've had a few times where there was no reason for the patient to not be able to refuse, but based on how the call came in the doc wanted to talk to the patient in person to verify the story and make sure there were no life threatening issues. The core of how they are required to go to the ER pretty much involves that once we have been called the active duty members are TDY to the ER until a doc discharges them, however that may be. One of the most common reasons we get is intoxicated and unable to safely care for oneself and nobody else present able to safely care for the patient, but my personal favorite reason is getting called for a SI when it wasn't that at all and then getting forced to take the patient in because sometimes the doc won't listen to the whole story of what's going on and that there was no SI at all.Just so I'm totally clear: you told the Alert and Oriented patient, who wasn't suicidal or anything, they are going to the hospital; the patient didn't want to, so you directed the MPs to place the soldier in handcuffs, and forced them to be treated and transported to the hospital. When was the last time you had the MPs forcibly restrain a soldier because you wanted to take them to the hospital, but they didn't want to go? Was that what happened a few weeks ago?
In your example, they are consenting, albeit under the potential threat of force by the MPs.
The same argument can be made in the civilian world: anytime the patient is given the choice of go to the ER and go to jail, the patient is most likely to up in the ambulance faster than the crew makes it to the truck. And we all know the legality of that choice is VERY questionable in most circumstances...
Personally, I want to see the law or military regulation that states upon enlistment, an active duty soldier loses the right to determine his or her medical care (which is exactly the situation that you are describing).
