Create a standard representation for radiotherapy data. Specifically, what level of granularity for procedures and which details should be recorded as modifiers.
Factors
Type
Phase / course
Technique
Site
Modality
Intent
Fractions
Dose/Volume
Planned vs. Delivered
Start date and end date (if procedures)
Others?
Proposed Solutions
We need to identify what level of granularity the actual "procedure" of the radiotherapy will be and consequently what modifiers will be needed to fully represent the relevant details.
Assuming we want to have the standard target concept (procedure domain) be more specific than "radiotherapy" with a bunch of modifiers, is there a hierarchy of procedures that we can leverage?
Another factor is that all of the above is referencing data sources that contain detailed radiotherapy data but we also need to account for the more generic radiotherapy procedures which lack this detail, e.g. from billing codes alone, and how we can accommodate both types in a similar manner to enable straightforward phenotyping.

One suggestion has been to reference the "Astro Minimum Data Elements for Radiation Oncology". An article on this can be found here: https://www.practicalradonc.org/article/S1879-8500(19)30232-2/fulltext
