In a mapping process, the Vocabulary team regularly encounters source drugs that do not specify any ingredients, but which determine a certain pharmacological category. In such a case we cannot use the RxNorm or RxNorm Extension whilst ATC drug categories look suitable except the fact they are classifications, so we cannot use them.
However, entries that we lose when targeting the concept id to 0 could be useful for identifying certain patients, for example:
- Unspecified insulin can be an indicator of patients with Diabetes Mellitus.
- Unspecified low-molecular-weight heparin gives us people at risk for bleeding.
- Unspecified interferon indicates patients on immunotherapy and with altered immunity.
Dear experts, is there hope that categories of drugs will become standard one day?
