Migrating from paper forms to SDC digital forms follows a specific sequence.
Step 1: Inventory current forms. Cataloged by workflow, volume, complexity.
Step 2: FHIR resource mapping. Each form → Questionnaire; answers → target resources.
Step 3: Terminology binding. Coded fields → ValueSets.
Step 4: Renderer selection. SDC-conformant with mobile UX.
Step 5: Pre-population + extraction design. FHIRPath expressions for both.
Migration timeline (per form)
| Step | Duration |
|---|---|
| Inventory | 1-2 weeks |
| Resource mapping | 1-3 weeks |
| Terminology | 1-2 weeks |
| Renderer choice | 1 week (one-time) |
| Pre-population | 1-2 weeks |
| Extraction | 2-4 weeks |
Bulk digitization
1. Prioritize by volume + complexity. 2. Template similar forms. 3. Central terminology governance. 4. Common rendering platform. 5. Shared extraction patterns.
Common mistakes
1. One-off implementations. 2. Missing terminology bindings. 3. Client-side calculation. 4. No pre-population. 5. Manual downstream integration.
ROI (moderate clinic, 50k intake forms/year)
| Impact | Value |
|---|---|
| Manual entry saved | ~$150k |
| Error correction saved | ~$30k |
| Compliance risk | Variable |
Vendor tooling
1. Aidbox Formbox — full SDC + bundled. 2. LHC-Forms — open, reference implementation. 3. Smile CDR SDC — commercial HAPI.
Digital forms migration is production-mature. The five-step approach scales across form portfolios.
