Discrepancy in number of records generated for ConditionOnset and Procedure states

[cgavali]

Hi,
Completely new to Synthea, Was just trying a sample custom module to generate 1000 patients. However, found that there were 1000 records generated in encounter and conditions files, but only around 113 in the procedures.csv. Could anyone please help in understanding why including a conditiononset state messes with the distributions and number of records generated.

Here's the sample module:
{
"name": "Debug_Test_Minimal",
"remarks": [
"Ultra-minimal test - no duration specified for procedure"
],
"states": {
"Initial": {
"type": "Initial",
"direct_transition": "Testcond"
},
"Testcond": {
"type": "ConditionOnset",
"codes": [
{
"system": "SNOMED-CT",
"code": 254837009,
"display": "breast cancer"
}
],
"target_encounter": "enc",
"direct_transition": "enc"
},
"enc": {
"type": "Encounter",
"encounter_class": "ambulatory",
"codes": [
{
"system": "SNOMED-CT",
"code": 86013001,
"display": "enc start"
}
],
"direct_transition": "proc"
},
"proc": {
"type": "Procedure",
"codes": [
{
"system": "SNOMED-CT",
"code": 24623002,
"display": "exproc"
}
],
"direct_transition": "end_enc",
"reason": "Testcond",
"distribution": {
"kind": "UNIFORM",
"parameters": {
"low": 30,
"high": 60
}
},
"unit": "minutes"
},
"end_enc": {
"type": "EncounterEnd",
"direct_transition": "Terminal"
},
"Terminal": {
"type": "Terminal"
}
},
"gmf_version": 2
}

Also, I am individually executing this module as backup.json
./run_synthea.bat -m *backup -p 1000

Two things.

FIrst, do not use -m: https://github.com/synthetichealth/synthea/wiki/The--M-Feature.

Second, this is probably to do with "years of history" which is a frequent topic in the Discussion boards here. The most recent being several days ago: #1586. Although you are having the opposite problem: the procedures are getting filtered out because they are outside the default time window and they are not active, but the condition diagnosis is active.

From the documentation, https://github.com/synthetichealth/synthea/wiki/Common-Configuration#other-export-settings, the setting exporter.years_of_history:

The number of years of patient history to include in patient records. For example, if set to 5, then all patient history older than 5 years old (from the time you execute the program) will not be included in the exported records. Note that conditions and medications that are currently active will still be exported, regardless of this setting. Set this to 0 to keep all history in the patient record.

Because your module has no Guard or Delay or anything like that, you are immediately diagnosing newborn babies with Breast Cancer then conducting an "exproc" on them.
