Duke Treadmill Score
Predicts prognosis from exercise treadmill testing and identifies low-, moderate-, and high-risk patients
- Highest activation tier
- Recommended
- How it is scored
- Scored in code; a stated value is compared only from the structured summary or a supplied value
- Scoring type
- formula
- Care settings
- Outpatient
When it activates
Scribeable activates a calculator from the encounter. The Duke Treadmill Score can activate when the transcript or pasted chart context documents any of these:
- Exercise stress test interpretation
- Treadmill test prognostication
- CAD risk stratification post-stress test
- Coronary angiography decision
Note-type scope: it activates on notes whose subject resolves to cardiology, 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.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| Exercise time in minutes on Bruce protocol | exam | min | |
| Maximum ST-segment deviation in mm | exam | mm | |
| Exercise angina index: 0=none, 1=non-limiting, 2=exercise-limiting | symptom |
Scoring
Duke Treadmill Score = Exercise time (min) - 5 × (max ST deviation mm) - 4 × (exercise angina: 0=none, 1=non-limiting, 2=limiting). Range typically -25 to +15.
Duke Treadmill = Exercise time in minutes on Bruce protocol − 5 × Maximum ST-segment deviation in mm − 4 × Exercise angina index: 0=none, 1=non-limiting, 2=exercise-limiting
Interpretation
≥5: Low risk (0.25% annual mortality). -10 to 4: Moderate risk (1.25% annual mortality). <-10: High risk (5.25% annual mortality, consider angiography).

How Scribeable handles it in the note
When an encounter activates the Duke Treadmill Score (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 Duke Treadmill Score 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.
