Ultimately, yes, I do. Though I realize that certain people have strengths and weaknesses, it becomes much more difficult to staff a unit if only certain people do certain things (ie, only one nurse certified to do ECMO or handle nitrous oxide, or only certain people who can start IV's with their eyes closed, or only certain people who can handle cardiac drugs, etc.). What happens if someone can't come in to work and there is no qualified staff to handle particular cases? I don't think that newborn nursery nurses should have to do that; I think that should be a seperate pool of staff. Some nurses want to work with healthy babies, others do not. Just like some nurses want to work Med/Surg and others would prefer Psych or ICU. In the NICU, however, I think that all the nurses should be able to handle the critical babies, or else they should exist as two entirely seperate nurseries with two seperate pools of staff (ie, one staff for the NICU/Level III and one staff for the ICN/Level II).
Certainly, the Level III nurses should be competent enough to handle the lower levels; if they can nurse a 23 weeker, they should be able to admit a healthy infant and handle what comes in between. I don't, however, think that they should automatically be pulled to those other units to staff when they are short. I think that's punishing them for being competent. If they are going to be pulled if they primarily work in the NICU/Level III, that should be made clear when they are hired so that they can make an informed decision as to whether or not they want to work there.
In my facility, not only are we expected to staff both the Level II and III nurseries, but we get pulled not only to Well-Baby (which I don't mind at all) but to every single department within Maternal/Child (including L&D, Postpartum, High Risk Antepartum, Peds ER, Inpt Peds, and PICU, which I DO mind).
