They are using medication aides in my state. The rules are very specific regarding what they can and cannot do. They only pass pills, they don't do any treatments or mess with tubes and such. No narcotics either. This is leaving the LPNs more time to be with their patients, to actually go back and assess prn meds, and is cutting down on med errors since they are not being distracted during med passes.
I don't think they're weeding out the LPNs, I think they're giving them a little help.
