What this is

A 500-patient evaluation slice of the XpertSystems HC01 synthetic Type 2 Diabetes dataset, released for technical evaluation, academic research, and benchmarking. The full commercial product covers 25,000+ patients with complete statistical validation, ML feature packs, and a Grade A+ benchmark report.

This sample is intended to let ML engineers, data scientists, and health-economics researchers verify the statistical fidelity and schema quality of the data before evaluating the full product. It is not sized for model training at production scale — rare events, long tails, and cross-cohort signal are materially underrepresented at 500 patients.

What's included

Six CSV files covering a 5-year patient journey:

File	Rows (approx.)	Description
patient_master.csv	500	One row per patient. Demographics, SDOH risk, diagnosis date, baseline biomarkers, comorbidities, insurance, care-site assignment.
patient_encounters.csv	~8,400	Longitudinal encounters (office, telehealth, specialist, ED, inpatient, RPM, care management). Includes biomarkers at visit, ICD-10, provider, payer, copay, care-gap flags.
medication_orders.csv	~6,200	Prescription orders across 10 T2D drug classes (metformin, SGLT2, GLP-1, insulin, etc.). Includes MPR/PDC adherence, prior authorization outcomes, formulary tier, titration and discontinuation events.
complications_registry.csv	~960	Diabetic complications (nephropathy, retinopathy, neuropathy, CVD, amputation, etc.) with onset date, severity stage, referral and treatment flags.
lab_results_longitudinal.csv	~19,600	HbA1c, fasting glucose, lipid panel, UACR, eGFR, and screening labs. Includes critical-value flags, follow-up lag, duplicate-lab and care-gap anomaly flags.
population_summary.csv	~600	Care-site × quarter aggregates: panel size, utilization rates, population-level glycemic control, care-gap rates.

Not included in this sample: the simulation engine, ML feature pack, statistical validation report (metrics.json), benchmark scoring artifacts, and the full-volume dataset.

Quick start

from datasets import load_dataset

# Load any of the six tables
patients = load_dataset("xpertsystems/hc01-t2d-sample", "patient_master")
encounters = load_dataset("xpertsystems/hc01-t2d-sample", "encounters")
labs = load_dataset("xpertsystems/hc01-t2d-sample", "labs")

print(patients["train"][0])

Or with pandas directly:

import pandas as pd
from huggingface_hub import hf_hub_download

path = hf_hub_download(
    repo_id="xpertsystems/hc01-t2d-sample",
    filename="data/patient_master.csv",
    repo_type="dataset",
)
df = pd.read_csv(path)

Schema highlights

Entity keys: patient_id (PAT#######) links all tables. encounter_id, order_id, lab_id, complication_id are unique per-row. site_id and payer_id link encounters to care sites and payers respectively.

Temporal structure: A 5-year simulated observation window. Quarterly patient-state updates drive encounter, lab, and medication timing. Dates are ISO-format (YYYY-MM-DD).

Coding standards: ICD-10-CM for diagnoses and complications; RxNorm-style codes for medications (representative, not authoritative); LOINC-aligned lab types.

Realism controls present in this sample:

• Anomaly flags on labs, encounters, and medication orders for data-quality testing
• Duplicate-lab and care-gap anomalies at calibrated base rates
• Prior-authorization denial cascades affecting adherence
• Coverage disruption events with downstream adherence penalties
• Death flags with dates (where applicable)
• SDOH-driven adherence heterogeneity

How this was generated

HC01 is produced by a deterministic simulation engine that models a synthetic T2D patient population through a calibrated sequence of stochastic processes. Patient demographics, comorbidities, and social-determinant risk are sampled from distributions aligned to public U.S. population references (CDC National Diabetes Statistics Report, NHANES, HEDIS MY2023). Each patient's HbA1c trajectory is modeled as a mean-reverting stochastic process conditioned on adherence, treatment intensification, and seasonal variation. Medication adherence (MPR/PDC) is drawn from a Beta distribution and modified by prior-authorization outcomes, copay burden, and coverage disruptions. Complication incidence follows a proportional-hazards formulation with hazard ratios for HbA1c, disease duration, CKD stage, and blood pressure, calibrated to published rates. Encounter, lab, and medication-order streams are generated conditional on patient state at each quarter, with ordering rates aligned to HEDIS Comprehensive Diabetes Care benchmarks. A small, controlled fraction of anomalies (duplicate labs, implausible values, care gaps) is injected to support data-quality and anomaly-detection use cases.

All simulation is deterministic under a fixed integer seed. The full commercial product ships with a 12-metric benchmark validation report certifying fidelity to published clinical and utilization targets (Grade A+ at default parameters).

Suggested evaluation workflow

1. Schema & volume sanity check. Load all six CSVs, confirm row counts and join integrity on patient_id.
2. Distribution checks. Verify baseline HbA1c mean (8.2%), BMI distribution (33.2 kg/m² mean), comorbidity prevalences, and insurance mix against the references above.
3. Correlation checks. HbA1c–BMI correlation (~0.28), HbA1c–complication incidence monotonicity, adherence–outcome relationships.
4. Longitudinal behavior. Plot individual HbA1c trajectories; verify mean reversion, seasonal component, and separation between adherent and non-adherent cohorts.
5. Edge-case coverage. Review anomaly flags, critical-lab follow-up patterns, prior-auth denial cascades.
