I think there is a real problem with neuro being the "dump" unit for all the patients that don't "fit" elsewhere. (i.e., patients no one else wants.) Face it, the Central Nervous System is something that everyone has... it's going to be affected in almost any metabolic alteration... if you let Admissions get away with it, Med-Neph will only get Med-Neph patients, and Ortho will only get patients with fractures, and GSU will only take patients after belly surgery, and Oncology will only get cancer patients on chemo, and so on. But NEURO gets anyone who's altered... PLUS everyone else's overflow.
You need a nurse manager who is a strong advocate. (And it doesn't hurt to have neurologists and neurosurgeons in your corner making the argument for you either.)
I'll tell you how that nonsense got stopped (mostly) in our hospital. The admissions supervisor at our place would fill our beds with patients no one else wanted (uninsured bariatric patients with boils in their butt-cracks, homeless people who have a clean CT scan but want a warm bed on a cold night, suicide gestures, little old ladies from nursing homes with catheter associated UTI's, etc, etc.) And once our unit was full... an acute stroke patient would roll in. Or a patient on another unit would have a seizure. Or a SDH-post craniotomy patient would need a bed. Or that cancer patient would suddenly be unable to move their legs or empty their bladders... in other words, there would be patients who needed to be cared for by neuro nurses.
Then... golly gosh! THe nurses on Med-Neph, or ortho, or GSU or Onc suddenly didn't want those admissions. And would you believe it? Neurosurgeons didn't want to send their fresh back surgery patients to non-neuro units.
So, what goes around comes around. If administration lets the Neuro unit be used as a dumping ground, then there might as well not be a neuro unit.
