Vaccinate 10% of the population
Once, every five years
Target only unvaccinated people

8. Overview Individual Properties - Refresher
New Intervention Status – Making Cascade State Generic
New Node Properties – Individual Properties for Nodes

9. Background Documentation
Cascade State is “used to set the category of healthcare associated with the intervention.”
“…enables easier tracking of individuals and visualization of the health care system.”
Abstraction
Allows user to define health care system at an abstract level
Each Cascade State can be a collection of interventions

10. Example OnART HIVMuxer ARTBasic HIVMuxer ARTDropout HIVRandomChoice
HCTUptakePostDebut3
LostForever0

11. Background (cont.) An individual has a state
An intervention can set a person’s state
An intervention has abort/invalid states such that:
Cannot be distributed if person’s current state is one of the abort states.
Will abort Update() if person’s state changed to an abort state

12. Abort & Update Distribute? Update
CascadeState is not in Abort_States, so “Distribute”

"class“ : “HIVMuxer",
"Abort_States“ : [ "LostForever" ],

"class“ : “HIVMuxer",

OnART
CascadeState is not in Abort_States, so UpdateState

13. Valid Cascade States config.json Cascade States are:
"",
"ARTStaging",
"ARTStagingDiagnosticTest",
"LinkingToART",
"LinkingToPreART",
"OnART",
"OnPreART",
"HCTTestingLoop",
"HCTUptakeAtDebut",
"HCTUptakePostDebut",
"TestingOnANC",
"TestingOnChild6w",
"TestingOnSymptomatic",
"LostForever" ],
Cascade States are:
used in the campaign file, but
defined in the config file.
Intervention values must be in this list
Cascade_State
Abort_States

14. Why Generic?
Needed feature to prevent individuals from getting drugs from different distribution mechanisms
Drugs via reactive care vs Drugs via drug campaign
Distributing a drug cocktail (i.e. multiple drug interventions)
Involves multiple interventions - concept that spans multiple interventions
Unlike HIV, some of these interventions can be node-level.

15. Move to Individual Properties
New Property Key/Name
InterventionStatus
User defines possible statuses in demographics instead of config
Benefit is that it is easy to start people with a particular status
i.e. Property distribution
Every intervention can have:
Disqualifying_Properties
New_Property_Value
Notice Term Change: CascadeState = InterventionStatus
Was Abort_States
Was Cascade_State

16. Demographics Example Best to define a default status, like “None”
"IndividualProperties": [ {
"Property": "InterventionStatus",
"Values": [
"None",
"ARTStaging",
"ARTStagingDiagnosticTest",
"LinkingToART",
"LinkingToPreART",
"OnART",
...,
"LostForever" ],
"Initial_Distribution": [
1, 0, 0, 0, 0, 0, ..., 0 ] }
Best to define a default status, like “None”
Everyone should probably start with that status
CANNOT user overlays with Individual Properties
Arrays cannot be overlayed

17. Intervention Example “Key:Value” format used
Can use in Property Restrictions to only target people with a give state
Person just needs to have one of the invalid properties for the intervention to abort.
Other properties can be invalid as well.

18. Overview Individual Properties - Refresher
New Intervention Status – Making Cascade State Generic
New Node Properties – Individual Properties for Nodes

19. Node Properties Represent node, not people in node{
"Property": "Place",
"Values": [ "RURAL", "URBAN"],
"Initial_Distribution": [ 0.85, 0.15 ] },
"Property": "InterventionStatus",
"Values": [
"NONE",
"SPRAYED_A",
"SPRAYED_B",
"FENCE_AND_TRAP" ],
"Initial_Distribution":
[ 1.0, 0.0, 0.0, 0.0 ] }
"Nodes": [
...
Represent node, not people in node
Similar to Individual Properties
One or more properties per node
Node-level interventions can target nodes via properties
InterventionStatus feature
NodePropertyValueChanger
