Best SDC Form Tools for Pre-Op Patient Intake in 2026

Pre-op patient intake is the single largest structured-data capture event in most surgical workflows. The form set typically covers medication reconciliation, prior surgeries, allergies, anesthesia screening, a stack of risk scores, and a procedure-specific consent. Done well in SDC, the same form set drives the anesthesia plan, the case posting, and the day-of-surgery checklist. Done poorly, it becomes another stack of paper that the OR nurse re-keys at 6 a.m. The tools below are the ones worth a serious pilot for a pre-op program in 2026. The FHIR form builder buyer's guide covers the underlying procurement frame.

For more reviews along these lines, the FHIR tooling roundups is the place to keep building the shortlist.

The Tools That Hold Up for Pre-Op

  1. Formbox. Strong on the branched-questionnaire pattern that anesthesia screening demands. Authoring is clinician-friendly enough that the nurse anesthetist updating the screening form does not need to file an engineering ticket.
  1. Aidbox Forms. The SDC expression engine is mature enough to compute the ASA physical status classification on the fly during intake. That kind of in-form calculation is what separates a pre-op tool from a survey tool.
  1. Smile Digital Health Forms. Pairs the SDC engine with the broader Smile FHIR server, which is already common in hospital deployments. Suits hospital pre-op programs that already have Smile on the back end.
  1. LHC-Forms. The NLM renderer is the open-source baseline. A surgery program embedding pre-op questionnaires inside an existing patient portal often starts here because the renderer is free and well-trusted.
  1. Open Health Hub. The PROM-oriented design fits a pre-op program that also wants to collect baseline patient-reported outcomes for surgical-quality reporting. Two birds, one form library.

What Makes Pre-Op Forms Different

Most generic SDC form tools handle a flat list of questions well; pre-op stresses the parts of SDC that are less commonly used. Repeating groups carry the medication list and prior-surgery list, which means the renderer either handles the SDC repeats and enableWhen patterns cleanly or it generates a deeply nested mess. The 7 SDC form tools that handle repeating groups well breakdown is where to verify this before committing.

Computable expressions are the second pressure point. ASA scores, STOP-BANG OSA screening, and procedure-specific risk indices are all derived values that the form has to compute and store as part of the QuestionnaireResponse. Tools that only support display logic and not computation push that work back to the EHR integration layer, which adds latency the OR cannot absorb.

For the adjacent intake use case where regulatory and billing pressure dominates, the best FHIR form builders for workers comp intake review covers a different shape of the same problem.

The Practical Procurement Move

Most pre-op programs will pick the tool that already pairs with their existing FHIR server. The tie-breaker is whether the vendor can show a working ASA-score or STOP-BANG calculation inside the form, computed in the renderer and stored in the QuestionnaireResponse. Anyone who can demo that in a 30-minute call is a serious candidate; anyone who hedges is selling a survey tool with a FHIR label. Pre-op programs that already use a specific EHR or surgical scheduling system should start with whichever form tool integrates with that system natively, then check whether the SDC capability bar is high enough.
