Most of the people who answer the phone are young, naive, can be easily sucked into the Axis II although the young folks have good intentions at heart.
While I was at U of Cincinnati, the ER-psych staff, residents, attendings were all on the same page with keeping malingerers out, with people we didn't know we'd thoroughly evaluate them and write the record so that if they showed up again the next clinician would be up to speed on this person.
So I moved out of that area and moved to a new area and joined another institution. There was no ER psych, the ER docs wanted psych patients out of the ER ASAP without thoroughly vetting if they really needed to be admitted, and add on top of this the inpatient psych attendings rotated every 2 weeks among about 8 doctors (but 2 were on duty at a time). I was the only attending that would kick out people where it was blatantly apparent the patient was manipulating the hospital.
So I sincerely tried to get that system changed. Several of the other psychiatrists more or less voiced they would never discharge a patient who wanted to stay saying it wasn't "compassionate." Anti-social and other cluster B patients were filled up the inpatient unit that weren't appropriate for the unit leading to assaults against truly sick patients, those same patients having their homes robbed (cluster B patients would befriend the truly sick patients, get their info, and have an accomplice break into that patient's home) and I brought it up in department meetings but was pretty much ignored.
There were even patients other attendings thought were malingering and wanted me to check them out, but instead of doing the easy and right thing, and discharge the patient themself, or the next best thing, that would be call me up and ask me to check the patient out despite that we had a rotation schedule on inpatient and I was doing something else at that time, the attendings who did this already wrote the patient was "suicidal" even though they didn't believe the patient was suicidal.
So I'd tell them I thought the patient could be discharged but they created a paper mess on the chart where two doctors have conflicting opinions, and because of this I couldn't endorse a dischage, and then the other attending would tell me "but I have to protect myself. I was hoping you'd discharge the patient so I wouldn't have to do it."
I had one patient one day, I walked into his room, and he said "om my god it's you doctor," cause he was from Cincinnati and said, "I know it you're going to kick me out right?" I recognized who he was. He was a known malingerer. I asked him what he was doing in this new city 5 hours away and he told me he hooked up with this girl over the Internet, decided to move over to this new city to give it a try, it didn't work out and he had no place to stay after she kicked him out so he decided to do his usual thing. That is go to the ER and say he was suicidal. I discharged him. He told me he had been in the inpatient unit about 1 week and was even considering moving to this new city permanently cause it was so easy to be admitted. HE was at least nice and polite so I told him my usual in a polite manner. Get out of the hospital, get a job, and stop pretending he's suicidal whenever he has a problem.
When I was on duty, I remember walking into work on a Monday morning and out of my 15 patients literally discharging over 10 the first day. Residents even telling me, "I was counting the days you would come in so we could kick this malingerer out." That was yet another reason why I left that place. That place is still in shambles from what I hear.
So the question is how to deal with it? While I was at U of Cincinnati it was handled the right way. I tried to get it handled the right way at the new place and was pretty much told patients would get to stay as long as they wanted. I left. That's how I dealt with it. I couldn't fight the fire in the house cause my department didn't want to do so. I decided instead to walk away from it.
