What are some of the challenges with quality measures related to primary medication nonadherence?
I think even defining what primary nonadherence is is a problem in developing the measure. How many days out does a patient have to be or how many days late does a patient have to be in picking up their prescription before they're "nonadherent"?
For some acute conditions, I think, 5 or 7 days you could deem the person nonadherent. But there are other types of medications where a patient could not pick it up for 30 days and I think that would be fine. So I think there are some very basic problems with measuring but I think we have to start with defining what nonadherence is.
