I'm wondering if anybody else has noticed the horrible trend of the ER staff completely disrespecting all most of the people that come in writing all of them off as drug and alcohol addicted persons before they do their mandated duty of making sure i

Many factors and not enough space to answer. Nurses are just as liable as MD's for dereliction of duty. Just not enough litigation. Yet!

First, we're not disrespecting anyone. In a world where we see a large percentage of people who are in the ED due to substance use and abuse and the fact that people lie to us all day long, we are also mindful that we have lives and licenses to protect. Overdoses happen. Drug abuse happens, and providers have to be mindful about what they are prescribing because if that patient goes home and overdoses on it, they're liable.

On House, MD, he famously says, "everybody lies", which is completely accurate. If I had a dollar for every patient that said they had sickle cell anemia and were in crisis and they didn't even have the disease, I'd be pretty rich. Thankfully, doctors are ordering differentials on patients who claim sickle cell pain, pulling PMPs on people coming in for toothaches, etc to see how many ERs they've been to and what pain medication they've been prescribed. Had one just last night.
3 ER visits and 3 narcotics prescriptions in less than 48 hours!

Unfortunately this happens quite a bit. I used to be an RN at a local hospital in the ER and saw this quite a bit. Its actually part of the reason I got out of the field. As someone new in nursing you work your butt off while other nurses cherry pick the patients in the waiting room and we wonder why the waiting rooms get backed up. Sometimes but not alway your ED doctors can be slow. I found it very frustrating for multiple reasons. Yes I took a pay cut to get out of nursing but it was the best decision for me and my family. Money doesn't buy happiness.

Yes thats what I see also.
