Arm measurements

[Jbrownwise]

Our IVT team measures (both) upper arm circumferences at the time of PICC or midline placement, and also every 3 days.  Most of us look upon the every 3 day measurements of both arms as a waste of valuable nursing time and energy and would like to delete it from our practice.  Are there any studies showing that this is a worthwhile practice?  Or does anyone have any anecdotal evidence that this is a worthwhile practice?  What do you PICC nurse educators recommend?  We're all ears!  Janet Brown-Wise
