🧠 2HELPS2B Seizure Risk (cEEG)
UseWhen to use: after ~1 h cEEG in acutely ill inpatients (not elective EMU).
StrataRisks ~5–>95% for scores 0–6+; duration cues 1 h / 12 h / ≥24 h for 0 / 1 / ≥2.
LimitsWhen not to use: elective epilepsy monitoring / typical post-arrest p… · Pitfall: mislabeling GRDA plus. · Not a sole AED start.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| BIRDs (brief potentially ictal rhythmic discharges) | No (0) |
|---|---|
| LPDs, LRDA, or BIPDs | No (0) |
| Prior seizure (acute or remote) | No (0) |
| Sporadic epileptiform discharges | No (0) |
| Frequency >2.0 Hz for any periodic/rhythmic pattern | No (0) |
| “Plus” features (superimposed rhythmic/sharp/fast) | No (0) |

- Est. seizure risk：~5%
- Monitoring cue：If no seizures on ~1 h screen and suspicion low, shorter monitoring often discussed
| BIRDs (brief potentially ictal rhythmic discharges) | Yes (+2) |
|---|---|
| LPDs, LRDA, or BIPDs | Yes (+1) |
| Prior seizure (acute or remote) | Yes (+1) |
| Sporadic epileptiform discharges | Yes (+1) |
| Frequency >2.0 Hz for any periodic/rhythmic pattern | Yes (+1) |

FAQ
Frequently asked questions
- Does 2HELPS2B Seizure Risk (cEEG) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is 2HELPS2B Seizure Risk (cEEG) calculated in practice? Can you show a worked example?
- Inputs: BIRDs (brief potentially ictal rhythmic discharges) No (0), LPDs, LRDA, or BIPDs No (0), Prior seizure (acute or remote) No (0), Sporadic epileptiform discharges No (0), Frequency >2.0 Hz for any periodic/rhythmic pattern No (0), “Plus” features (superimposed rhythmic/sharp/fast) No (0) → Result: 2HELPS2B 0 /7（Est. seizure risk: ~5%, Monitoring cue: If no seizures on ~1 h screen and suspicion low, shorter monitoring often discussed） Inputs: BIRDs (brief potentially ictal rhythmic discharges) Yes (+2), LPDs, LRDA, or BIPDs Yes (+1), Prior seizure (acute or remote) Yes (+1), Sporadic epileptiform discharges Yes (+1), Frequency >2.0 Hz for any periodic/rhythmic pattern Yes (+1), “Plus” features (superimposed rhythmic/sharp/fast) Yes (+1) → Result: 2HELPS2B 7 /7（Est. seizure risk: >95%, Monitoring cue: Consider ≥24 h cEEG）
