Glasgow-Blatchford Bleeding Score
Identifies low-risk upper GI bleed patients safe for outpatient management
- Highest activation tier
- Mandatory
- How it is scored
- Scored in code; a detected disagreeing draft value is flagged for correction
- Care settings
- Emergency department, Inpatient
When it activates
Scribeable activates a calculator from the encounter. The Glasgow-Blatchford Bleeding Score can activate when the transcript or pasted chart context documents any of these:
- Upper GI bleeding
- Hematemesis evaluation
- Melena presentation
- GI bleed disposition decision
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: K25, K26, K27, K28, K92.
Note-type scope: it activates on notes whose subject resolves to gi, hepatology, emergency medicine, 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
8 inputs. Each is resolved from the transcript, the pasted chart context and charted labs; an input marked "asks you" is requested as a clarification when it is undocumented.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| BUN level | lab | mg/dL | |
| Hemoglobin | lab | g/dL | |
| Systolic BP | vital | mmHg | |
| Heart rate >=100 | vital | bpm | |
| Melena present | symptom | ||
| Syncope | symptom | ||
| Hepatic disease | history | ||
| Cardiac failure | history |
Scoring
Points for BUN, Hgb (sex-specific), SBP, HR>=100, melena, syncope, liver disease, CHF
BUN BUN level + Hgb Hemoglobin + SBP Systolic BP + HR Heart rate >=100 + melena Melena present + syncope Syncope + liver Hepatic disease + CHF Cardiac failure
Interpretation
Score 0: Low risk (0.5% need intervention), safe for outpatient. Score >0: High risk, requires admission.

How Scribeable handles it in the note
When an encounter activates the Glasgow-Blatchford Bleeding Score at the mandatory tier, Scribeable resolves its inputs from the transcript, the pasted chart context and any charted labs, and asks you for a missing input you can supply before the note is finalised. Bedside-exam and separately ordered study values are not requested one input at a time; a calculator that carries a combined clarification question may still put that single question to you.
The score is computed in code from the resolved inputs, not recalled by the language model. If the draft states a Glasgow-Blatchford Bleeding Score value that disagrees with the computed one, the disagreement is flagged to the second drafting pass, which is instructed to correct the score and its interpretation before you see the note.
Classified as a risk score: activated strictly, by a documented trigger, never by a permissive reading of the encounter.
