International Prognostic Index (IPI) for NHL
Stratifies non-Hodgkin lymphoma patients into prognostic risk groups to guide treatment intensity
- Highest activation tier
- Mandatory
- How it is scored
- Scored in code; a detected disagreeing draft value is flagged for correction
- Scoring type
- point sum
- Care settings
- Inpatient, Outpatient
When it activates
Scribeable activates a calculator from the encounter. The International Prognostic Index (IPI) for NHL can activate when the transcript or pasted chart context documents any of these:
- NHL prognosis assessment
- Lymphoma risk stratification
- Lymphoma treatment planning
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: C82, C83, C84, C85.
Inputs the note needs
1 input. 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 |
|---|---|---|---|
| IPI score (0-5): age >60, stage III/IV, ≥2 extranodal sites, ECOG ≥2, elevated LDH | history |
Scoring
5 risk factors, each +1: age >60, Ann Arbor stage III/IV, ≥2 extranodal sites, ECOG ≥2, LDH elevated. Total 0-5.
Interpretation
0-1: Low risk (5-year OS ~73%). 2: Low-intermediate (51%). 3: High-intermediate (43%). 4-5: High risk (26%).

How Scribeable handles it in the note
When an encounter activates the International Prognostic Index (IPI) for NHL 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 International Prognostic Index (IPI) for NHL 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 staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
