Quote from purplemania
Someone who lacks self-confidence or cannot site evidence for changing a practice will use "the other hospital" to enhance credibility. Rather than become defensive you might ask them to write down their suggestions to be turned in to the supervisor for consideration. Maybe they just want to be seen and heard, not really be critical. We all want to feel like we contribute and so far I have not been in a hospital that could not stand a little tweaking. I agree the comment is irritating but perhaps it can be used for good.
This is amusing because as you said there is not a hospital that can't usse tweaking. There are things my old hospitals could learn from my newer ones as well. Some times managers ask for and acutally want suggestions from new nurses that that brought with them from an old employer. Suggestions from such nurses can be very insightful because they are not blinded by familarity of how we do things here.
Then there are those who only gives lip service
to "we want your suggestions and information on how your old hosp. did this"
Yes a new employee does need to learn the policy of the new facility and be aware that there is often more than one right way and one effective/effiecient way and this hospital's way may be just as good even better just different.
On the other hand I sometime observe is a closed mind on the part of the staff and management at the new facility to acknowledge that something may be wrong with or benifit from fixing that the new person has the answer to because of thier different perspecive and experience.
Sometimes the new employee is simply saying be patient with me I have a lot to learn about your ways as I did things very differently where I was last at.
