SVS WIfI Classification

When it activates

Scribeable activates a calculator from the encounter. The SVS WIfI Classification can activate when the transcript or pasted chart context documents any of these:

• Threatened limb assessment
• Diabetic foot evaluation
• Limb amputation risk assessment
• Critical limb ischemia with wound
• Ischemic ulcer staging

Note-type scope: it activates on notes whose subject resolves to perioperative, hospital medicine. A note that resolves to another subject does not carry it even when the clinician's specialty matches; a note with no resolvable subject (a generic consultation) falls back to the specialty match.

Inputs the note needs

3 inputs. Each is resolved from the transcript, the pasted chart context and charted labs; at this calculator’s tier a missing input is never requested, and a missing required input keeps the score out of the draft.

Scoring

Three components each 0-3: Wound (W), Ischemia (I), foot Infection (fI). Combined score determines clinical stage and estimated amputation risk.

Interpretation

Very low risk: all 0. Low risk: low grades. Moderate risk: mixed moderate grades. High risk: any grade 3 or multiple grade 2. Higher combined scores indicate greater benefit from revascularization.

How Scribeable handles it in the note

When an encounter activates the SVS WIfI Classification (its highest tier is recommended), Scribeable does not ask you for missing inputs. The score is computed in code from whatever inputs resolve from the transcript, the pasted chart context or charted labs; a computed value is written into the draft only when every required input already resolves.

The score is computed in code from the resolved inputs, not recalled by the language model. A stated SVS WIfI Classification value is compared against the computed one when the draft's structured summary carries it; a disagreement found there is flagged to the second drafting pass, which is instructed to correct the score and its interpretation, unless Scribeable has supplied the computed value to that pass, in which case the value the draft writes is checked against the supplied one and a detected difference is shown beside the note for you to adjudicate rather than silently rewritten.

Classified as a risk score: activated strictly, by a documented trigger, never by a permissive reading of the encounter.
