UniPACT-MDS-ED Prompted Dataset

A multimodal prompt-formatted version of the MDS-ED prognostic benchmark (built on MIMIC-IV-ECG + MIMIC-IV), used to train and evaluate UniPACT. Each example pairs a raw 12-lead ECG waveform with a natural-language prompt that textualizes structured EHR (demographics, biometrics, vital signs) plus a binary clinical question (Yes/No).

🔑 Access

This dataset inherits the PhysioNet Credentialed Health Data License from MIMIC-IV. Before you can download:

1. Create a PhysioNet account
2. Complete the required CITI "Data or Specimens Only Research" training
3. Sign the MIMIC-IV data use agreement

Without credentialing, the files will not be accessible.

📊 Task coverage

The dataset spans 1443 binary prognostic sub-tasks across four families:

Family	Sub-tasks	Description
Diagnosis	1428	Disease-level binary diagnosis classes
Deterioration	6	Acute clinical deterioration outcomes
ICU admission	2	ICU-related admission outcomes
Mortality	7	Mortality at multiple time horizons

Splits follow the official MDS-ED train / validation / test partition.

🧪 Examples

Each row contains a raw ECG tensor ((5000, 12) float array · 10 s @ 500 Hz · 12 leads), a textualized EHR prompt, a binary clinical question, and a Yes/No label. One real sample from each task family:

Deterioration — deterioration_severe_hypoxemia_362

ECG:  …/p16463772/s48979490/48979490

      temp 36.8, HR 77.5, RR 16.5, SpO₂ 99.5, BP 115.5/66.5, acuity 3.0.
Q:    Will the patient "require ICU admission within the next 24 hours"?
A:    Yes

Mortality — deterioration_mortality_1d_3

ECG:  …/p13953606/s48605173/48605173

      temp 36.3, HR 101, RR 20, SpO₂ 99, BP 156/81, acuity 1.0.
Q:    Will the patient "die within 24 hours"?
A:    No

Diagnosis — diagnoses_i10_0

ECG:  …/p11922120/s41055417/41055417
EHR:  66 y/o WHITE male; BMI 31.7, weight 118.1;
      temp 36.3, HR 81, RR 18, SpO₂ 99, BP 141/73, acuity 2.0.
Q:    Will the patient be diagnosed with "Essential (primary) hypertension"?
A:    No

Source data & construction

• Source benchmark: MDS-ED (Alcaraz et al., 2024)
• Underlying clinical data: MIMIC-IV-ECG and MIMIC-IV, collected at Beth Israel Deaconess Medical Center and de-identified under HIPAA Safe Harbor by the MIT Laboratory for Computational Physiology
• EHR textualization: 3 demographic + 3 biometric + 7 vital-parameter fields are inserted into fixed sentence templates
• Labels: derived programmatically from existing structured fields (ICD codes, ICU stay tables, mortality timestamps, MDS-ED deterioration outcomes) — no human re-annotation
• ECG: raw 12-lead waveforms kept in native form for waveform encoders; no conversion to text reports
