Yeah, we need to clean this up. And the question is, what do people need. Initially, we manually just picked a bunch of routes that deemed reasonsable:
Later, we added dm+d (UK-defined) routes, and some of them became standard concepts, which is a mistake. They are also the ones that created those called "Obsolete" but didn't deprecate them. Nothing we can do about (other than manually overwriting, which we try to avoid at all costs).
In addition, SNOMED actually has a specific set of Routes of Administration defined (148 of them), but they are a little unwieldy and have a hierarchy of 4.
What we should do is use the ones RxNorm or NDF-RT define. Let me bring it to the Workgroup.
100% agree. And we started building one, but it gets deprioritized all the time over bugs or terminology additions. And it would be really good if folks came with ideas of what would be good comparisons.
