Third-party libraries
The builder is dependency-light and bundles a few open-source libraries in lib/,
including:
- FHIRPath.js β the FHIRPath engine used by the runtime.
- marked β Markdown rendering (used for item text and this documentation).
- DOMPurify β HTML sanitisation for any rendered XHTML/Markdown.
Each retains its own license; see the files under lib/ in the repository.
Ready-made templates
The scales offered under + Add β From templateβ¦ keep their original wording and carry the credits their authors ask for. The picker shows each template's source and license before you insert it.
- PHQ-9, PHQ-2, GAD-7 and GAD-2 β developed by Drs. Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke and colleagues, with an educational grant from Pfizer Inc. No permission is required to reproduce, translate, display or distribute them (phqscreeners.com).
- AUDIT-C β a short form of the WHO AUDIT (Bush et al., Arch Intern Med 1998;158:1789). The ONC USCDI/ISP listing for AUDIT-C (submitted by NIAAA) states no restrictions on use (isp.healthit.gov).
- Clinical scales with original wording (Glasgow Coma Scale, Apgar Score, qSOFA, CHAβDSβ-VASc, Charlson Comorbidity Index; the scales are published clinical methods, each template lists its sources), intake fragments and calculators (demographics, allergies, medications, pain; body measurements, kidney function, cardiac measurements, lipid panel, chemistry calculations, FIB-4, pregnancy dating) β original wording written for this builder, covered by the project license above (non-commercial use with attribution; commercial use needs written permission). Calculator formulas are published methods; each template lists its sources.
- Codes β question and answer codes come from LOINC, copyright Regenstrief Institute, Inc., available at no cost under the LOINC license.
Attribution in exports
Questionnaires you export are your own FHIR data. The builder does not inject branding into exported resources beyond the standard FHIR fields you configure.
