Clinical software selection in 2026 favors FHIR-first products. Five criteria distinguish production-ready from checkbox-ready.
1. FHIR API completeness. Verify with Inferno, not marketing.
**2. SMART on FHIR support.** Universal expectation.
**3. US Core conformance.** Baseline for US.
4. Terminology binding depth. SNOMED CT, LOINC, RxNorm.
5. Vendor roadmap alignment. Keep pace with regulatory changes.
