I work oncology, so quite often we get to know the names of folks who come in frequently. It's a favorite thing to do on our unit, visiting those we haven't seen in awhile. I will also check on people who were transferred to other units if I cared for them for a length of time. Several of our nurses do this and it's always been welcomed by patients as well as family. I don't look up their charts, though, as I'm not their nurse anymore.
