I'm a new manager to a surgical ICU, medical ICU and step-down unit. I can assure you (and the staff will attest to this) that the "culture" in the medical unit is very different than that of the surgical unit. My personal observation is that in "general" the medical ICU nurses are "thinkers" & the surgical ICU nurses are "doers". I may have staff voluntarily engage in a confidential personality profile to compare the units & gain a greater understanding of the differences between these two cultures. Hmmmm.
