There are parts of this story missing so assupmtions have been made by many, but that isn't inappropriate. Several people have talked about the OP turning over care to the hospital staff. Why would the OP need to turn over care. The hospital staff were the first ones on the scene so they would need to turn over care to the EMS crew. Dwayne, as for people criticizing the OP and not making this educational, it is probably because of the last comment that he made about getting back into the ambulance and leaving. It doesn't sound as if he came here to have a discussion, rather to bash a situation he didn't like because of an ego issue. Had he asked what was the proper thing to do or just ask what others would do, it might have gone a lot differently. It's all in the presentation. As has been said about writting PCRs, it's about painting a picture and the picture here was not one of looking for advice but more of a bruised ego.
I would have no problem with an extra set of hands so I would be more than happy to have the OP help. Yes, I have assumed that the pt is within EMTALA range of the ER. In that case, the federal goverment has decided to put the burdon on the hospital so it just makes since for them to take control. Yes, I have also assumed that we are dealing with nurses going out to get the pt. Sure, it may have just been ER techs but it's pretty irrelevant. The pt needs to get into the ER. Instead of getting offended that things didn't go his way, the OP could have simply said, "Hey, I'll give you a hand getting him into the ER." He could have gone in and simply turned over the pt to the triage nurse by saying, "This guy was outside and your guys were getting him on the strecher before we got there. I don't know much else because I have been with the guy for all of 30 seconds and felt it would be better to get him in here than waste time outside." Once he is on the hospital grounds, according to CMS/EMTALA, he is the hospitals responsibility and as long as you have told someone about him, you have done your job.
