Dedicated med lines

I just wanted to get a sense of what other facilities do with their dedicated med lines that are attached to central lines that may have other things running through them. For instance if you have a patient with a PICC that has Maintenance fluids (not TPN), say milrinone and then your med line. Obviously we will assume if a med you are giving is not compatible with the milrinone you either turn the milrinone off briefly or give said med elsewhere.

My question is whether you cap the end of the med line with a needle less adapter In the NICU at my hospital, where I originally trained, we put a blue needle less port on the end of our med lines. Thus when giving meds we would scrub the hub, wait to dry and then give said med. The unit I work in now, historically, does not put any cap on the end of the line but leaves a flush hooked up to it. When you have to give a med you unhook the flush while simultaneously trying to clamp the end of the line to prevent air entry and drip med into port to "top off" and prevent air entry and then screw on the med. Med is given via syringe pump then process is repeated to flush the med. Meanwhile, there is nothing to scrub really when trying to prevent contamination

In my practice, since it is what I was taught, I continue to put a blue clave on all my med ports but this is not routine practice. Our unit practice council is actually working to make it routine but that is really only due to a recent spike in CABSI which in reality cannot necessarily be directly linked to this med admin method since that is how they have been doing it for years.

Thoughts?
