I am trying to interpret Standard 17 under "practice criteria A" states "The nurse should not use color coding , color differentiation, or color matching for product or medication identification. How do we document the lumen we are talking about on a PICC line. The manufacturers have colored each lumen. There are no numbers or names on these lumens. We are using electronic charting at our facility and they have the charting of the lumens of a PICC as "proximal, medial, and distal". We all know this is inaccurate. So how do we name these multi lumen catheters if we can't document them by their color? Or am I interpreting this Standard wrong?
