For those that may not know, I do medication reviews on nursing home residents. I look at their drug regimen, vitals, labs, etc and ensure everything is a-okay. One day I came across this gem.
Background: INR is a lab that is needed to monitor Coumadin, a blood thinner. It's used to ensure that the level is therapeutic. Being too high increases the risk of bleeding and being too low, it's not effective. This lab needs to be done frequently when on this drug.
And apparently, this particular resident was not on Coumadin.
