Our facility is looking at using a prn PICC nurse to place PICCs "after hours". My concern is that we will not be able to obtain x ray confirmation of tip location until the following morning, possibly as long as 18 hours after the PICC is placed. I'm uncomfortable with a potentially malpositioned PICC being in place for that length of time. Any thoughts on this? We do not use any type of tip locator during insertion and are unlikely to purchase one.
