🏥 Synthetic Privacy-Preserving Medical EHR Dataset

Dataset Description

A fully synthetic collection of 10,000 Electronic Health Records (EHRs) for binary classification research. The task is predicting adverse patient outcomes — deterioration or death — from clinical, demographic, and vital sign features. No real patient data was used at any stage. Privacy-safe under GDPR, CCPA, and HIPAA.

Supported Tasks

—tabular-classification: Predict adverse_outcome (0/1) from 13 clinical features
—Benchmark models: Random Forest, Gradient Boosting, XGBoost
—Class imbalance handling: SMOTE oversampling applied on training set only
—Interpretability: SHAP feature importance included in generation pipeline

Privacy Methods

This dataset was synthetically generated in Python. Privacy techniques applied:

1.Anonymization — UUID patient IDs, no real names or SSNs
2.Generalization — age buckets, region labels instead of cities
3.Differential Privacy — Laplace mechanism noise (epsilon=2.0) on all vital signs
4.Data Perturbation — Gaussian noise on continuous features

No real patient records were used or referenced at any stage.

Benchmark Results

Model	Val ROC-AUC	Accuracy	F1 Adverse	CV 5-fold
Random Forest	0.9535	89%	0.82	0.9707 ± 0.013
Gradient Boosting	0.9630	90%	0.84	0.9760 ± 0.013
XGBoost (best)	0.9665	91%	0.85	0.9769 ± 0.012
XGBoost (test)	0.9542	90%	0.85	—

Use Cases

—Binary classification for healthcare outcome prediction
—Benchmarking tabular ML models without privacy risk
—Teaching SMOTE, scaling, hyperparameter tuning, SHAP
—Fairness analysis across demographic groups
—Differential privacy and privacy-preserving AI research
