HealthSim - Synthetic Healthcare Data Generation

Overview

HealthSim generates realistic synthetic healthcare data through natural conversation. Rather than writing code or configuration files, describe what you need and Claude generates appropriate data.

Products:

Quick Start

Generate Clinical Data

Request: "Generate a 65-year-old diabetic patient with hypertension"

Claude will produce a patient with:

• Demographics (age 65, realistic name/address)
• Diagnoses (E11.9 Type 2 diabetes, I10 hypertension)
• Medications (metformin, lisinopril)
• Labs (A1C, BMP with values in expected ranges)
• Comorbidities (likely hyperlipidemia, possible obesity)

Generate Claims

Request: "Create a professional claim for an office visit"

Claude will produce:

• Claim header (provider NPI, member ID, service date)
• Service lines (CPT 99213/99214, charges)
• Diagnoses (ICD-10 codes)
• Adjudication (allowed, paid, patient responsibility)

Generate Pharmacy Data

Request: "Generate a pharmacy claim that triggers a drug interaction alert"

Claude will produce:

• Prescription details (NDC, quantity, days supply)
• Pharmacy claim (BIN, PCN, cardholder ID)
• DUR alert (DD code, clinical significance, recommendation)
• Claim response (approved with warning or rejected)

Scenario Skills

PatientSim Scenarios

Load these for clinical data generation:

See: skills/patientsim/ for detailed skills

MemberSim Scenarios

Load these for claims and payer data:

See: skills/membersim/ for detailed skills

RxMemberSim Scenarios

Load these for pharmacy and PBM data:

See: skills/rxmembersim/ for detailed skills

TrialSim Scenarios

Load these for clinical trial data generation:

See: skills/trialsim/ for detailed skills

PopulationSim Scenarios

Load these for population intelligence and cohort definition:

Key Differentiator: PopulationSim analyzes real population data (Census, CDC) and outputs specifications, not synthetic records. These specs drive realistic generation in PatientSim, MemberSim, and TrialSim.

See: skills/populationsim/ for detailed skills

NetworkSim Scenarios

Load these for provider network knowledge and entity generation:

See: skills/networksim/ for detailed skills

Generative Framework

Load these for batch generation and specification-driven data creation:

Key Differentiator: The Generative Framework enables specification-driven generation at scale. Build a profile, define a journey, then execute to generate hundreds or thousands of correlated entities across all products.

Common Skills

Cross-product infrastructure skills:

See: skills/common/ for detailed skills

Output Formats

Default: JSON

By default, Claude outputs data as JSON objects that match the canonical data model.

Healthcare Standards

Request specific formats:

See: formats/ for transformation skills

Analytics Formats

See: formats/dimensional-analytics.md for star schema details

Generation Parameters

Demographics

Clinical (PatientSim)

Claims (MemberSim)

Pharmacy (RxMemberSim)

Reproducibility

For consistent results across sessions:

Request: "Generate 10 patients using seed 42"

Claude will:

1. Use seed 42 for all random selections
2. Generate identical output if same parameters used
3. Note the seed in output for reference

Validation

Claude automatically validates generated data for:

• Structural: Required fields, data types, formats
• Temporal: Date ordering (discharge after admission, etc.)
• Referential: Foreign key relationships
• Clinical: Age-appropriate conditions, gender-appropriate conditions
• Business: Valid code combinations, realistic pricing

Request explicit validation: "Validate this patient data"

Tips

1. Be specific: "diabetic patient with A1C of 9.5" beats "sick patient"
2. Request format early: "Generate as FHIR..." rather than converting after
3. Use seeds: For reproducible test data across sessions
4. Batch large requests: "Generate 100 in batches of 20"
5. Validate sensitive data: Request validation for production-like scenarios
