## TL;DR

The ordering and record systems oncologists use every day, including built-in treatment pathways that steer drug choice.

## Summary

Epic Beacon, Oracle Health (Cerner) PowerChart Oncology, Varian ARIA, Elekta MOSAIQ, and Flatiron OncoEMR handle regimen ordering, dose calculation, and documentation; pathway programmes (NCCN-aligned Via Oncology/Elsevier ClinicalPath, US Oncology's Value Pathways, Dana-Farber pathways) embed evidence-based regimen choices and are tied to payer programmes. Structured data from these systems (mCODE) feeds real-world evidence.
