So I have noticed that we are having some picc line migration in patients that have had picc lines in for an extended period of time. My question is at what point do I need to worry or have a new xray to determine placement? I honestly think that it might be due to the stat lock device. Many of the nurses are not very comfortable using it. We are a small hospital, so it is not really feasible for the picc nurses to do all the dsg changes. Any suggestions?
