# Command-specific help
ignixa-fakes r4 resource --help
ignixa-fakes r4 scenario --help
ignixa-fakes r4 population --help

Usage

All commands start with a FHIR version and require an output folder:

ignixa-fakes <version> <command> --out <folder> [options]

Available FHIR versions: stu3, r4, r4b, r5, r6

Generate Single Resources

Generate a Patient resource with specific attributes:

ignixa-fakes r4 resource Patient --out ./output --firstname Bob --surname Smith --from Seattle

Generate an Observation using a predefined state:

ignixa-fakes r4 resource Observation BloodGlucose --out ./output

Generate Predefined Scenarios

Generate a complete patient scenario with related resources:

ignixa-fakes r4 scenario DiabeticPatient --out ./output --resolved-references

Available scenarios include:

• DiabeticPatient - Type 2 diabetes with medication escalation
• WellnessVisit - Routine wellness visit with observations
• UrinaryTractInfection - UTI diagnosis and treatment
• AsthmaticChild - Pediatric asthma management
• And many more...

Generate Populations

Generate multiple patients from a specific location:

ignixa-fakes r4 population --out ./output --from Seattle --count 100 --resolved-references

Generate populations in ndjson format (useful for $import operations):

ignixa-fakes r4 population --out ./output --from Seattle --count 100 --ndjson

Options

• --out <folder> - Required - Output folder for generated files (will be created if it doesn't exist)
• --resolved-references - Creates a batch bundle instead of references (for scenario and population commands)
• --ndjson - Write ndjson files instead of bundles (implies --resolved-references, only available for population command)
• --firstname <name> - Set patient first name
• --surname <name> - Set patient surname
• --from <city> - Generate from a specific city
• --count <number> - Number of resources/patients to generate

Output

All commands generate JSON files in the specified output directory with the format:

• Single resources: {resource}-{name}-{id}.json or patient-{id}.json
• Scenarios: bundle-{scenario}-{id}.json
• Populations (bundles): bundle-population-{city}-{count}-{id}.json
• Populations (ndjson): {version}-population-{city}-{ResourceType}-{count}-{id}.ndjson

Examples

# Generate a single patient from R4
ignixa-fakes r4 resource Patient --out ./output --firstname Alice --surname Johnson

# Generate a diabetic patient scenario using R4
ignixa-fakes r4 scenario DiabeticPatient --out ./output --resolved-references

# Generate 50 patients from Boston using R4 as bundles
ignixa-fakes r4 population --out ./output --from Boston --count 50 --resolved-references

# Generate 50 patients from Boston using R4 as ndjson files (for $import)
ignixa-fakes r4 population --out ./output --from Boston --count 50 --ndjson

# Generate a blood glucose observation using R4
ignixa-fakes r4 resource Observation BloodGlucose --out ./output
