Engel Epilepsy Surgery Outcome Classification

When it activates

Scribeable activates a calculator from the encounter. The Engel Epilepsy Surgery Outcome Classification can activate when the transcript or pasted chart context documents any of these:

• Post-epilepsy surgery outcome assessment
• Seizure freedom evaluation after surgery
• Epilepsy surgery follow-up
• Surgical outcome classification

Note-type scope: it activates on notes whose subject resolves to neurology. 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

1 input. 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

Class I: Free of disabling seizures (may have auras). Class II: Rare disabling seizures (almost seizure-free). Class III: Worthwhile improvement (>75% reduction). Class IV: No worthwhile improvement (<75% reduction).

Interpretation

Class I: Best outcome, seizure-free or only auras — considered surgical success. Class II: Rare seizures, generally favorable. Class III: Meaningful improvement but persistent seizures. Class IV: Surgery did not achieve meaningful seizure reduction. Approximately 60-70% of temporal lobe epilepsy surgeries achieve Engel Class I.

How Scribeable handles it in the note

When an encounter activates the Engel Epilepsy Surgery Outcome 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 Engel Epilepsy Surgery Outcome 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 staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
