I worked in a hospital that had a dedicated Peds unit. We also did Ambulatory srgery care on all peds, and on the adult one day surgery patients who stayed longer than Flexcare wanted. We were steadily busy, but in their wisdom, management decided to absorb the unit into m/s........ After all, any nurse can take care of a peds patient!
That's when I started job hunting. You won't be able to change the system, so if you are not happy it may be time to move on. To me, you either like peds or you don't. I realize that as a nurse we are supposed to take care of any patient, but I would have loved to see our Nurse Manager at that hospital come in and take care of ANY patient, never mind a Peds patient.
At that time, we were able to relocate, and I started work in a NICU. Look around, you may find that there is a position waiting for you, either where you are now, or in a new place. Good Luck!
