Ocular Surface Disease Index (OSDI)

When it activates

Scribeable activates a calculator from the encounter. The Ocular Surface Disease Index (OSDI) can activate when the transcript or pasted chart context documents any of these:

• Dry eye disease assessment
• Ocular surface disease evaluation
• Dry eye symptom severity
• Dry eye treatment monitoring
• Meibomian gland dysfunction evaluation

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

OSDI = (sum of scores for all answered questions) x 25 / (number of questions answered). Score 0-100. 0-12: Normal. 13-22: Mild dry eye disease. 23-32: Moderate dry eye disease. >=33: Severe dry eye disease.

Interpretation

Score 0-12: Normal ocular surface — no treatment needed. Score 13-22: Mild — artificial tears, environmental modifications, lid hygiene. Score 23-32: Moderate — prescription anti-inflammatory drops (cyclosporine, lifitegrast), punctal plugs, omega-3 supplementation. Score >=33: Severe — aggressive combination therapy, consider autologous serum tears, scleral lenses, or surgical intervention. Clinically meaningful change: >=7.3-point improvement (MCID).

How Scribeable handles it in the note

When an encounter activates the Ocular Surface Disease Index (OSDI) (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 Ocular Surface Disease Index (OSDI) 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 questionnaire: a patient-reported or clinician-rated instrument, where a spare activation carries low harm.
