SimpleHealthSeekingBehavior

The SimpleHealthSeekingBehavior intervention class models the time delay that typically occurs between when an individual experiences onset of symptoms and when they seek help from a health care provider. Several factors may contribute to such delays including accessibility, cost, and trust in the health care system. This intervention models this time delay as an exponential process; at every time step, the model draws randomly to determine if the individual will receive the specified intervention. As an example, this intervention can be nested in a NodeLevelHealthTriggeredIV so that when an individual is infected, he or she receives a SimpleHealthSeekingBehavior, representing that the individual will now seek care. The individual subsequently seeks care with an exponentially distributed delay and ultimately receives the specified intervention.

Note

Parameters are case-sensitive. For Boolean parameters, set to 1 for true or 0 for false. JSON does not permit comments, but you can add “dummy” parameters to add contextual information to your files.

The table below describes all possible parameters with which this class can be configured. The JSON example that follows shows one potential configuration.

Parameter Data type Minimum Maximum Default Description Example
Actual_IndividualIntervention_Config JSON object NA NA NA The configuration of an actual intervention sought. Selects a class for the intervention and configures the parameters specific for that intervention class.

        "Cost_To_Consumer": 1,
        "Drug_Type": "FirstLineCombo",

        "TB_Drug_Inactivation_Rate": 0.000000001,
        "class": "AntiTBDrug"
    }
}
Actual_IndividualIntervention_Event enum NA NA NoTrigger The event of an actual intervention sought. Selects a class for the intervention and configures the parameters specific for that intervention class. See Event list for possible values.
{
    "Actual_IndividualIntervention_Config": {
        "Actual_IndividualIntervention_Event": "ProviderOrdersTBTest",
        "Tendency": 0.005,
        "Event_Or_Config": "Event",
        "class": "SimpleHealthSeekingBehavior"
    }
}
Single_Use boolean NA NA 1 If set to true (1), the health-seeking behavior gets used once and discarded. If set to false (0), it remains indefinitely.
{
    "Single_Use": 1
}
Tendency float 0 1 1 The probability of seeking healthcare.
{
    "Tendency": 0.01
}
Event_Or_Config enum NA NA Config

Specifies whether the current intervention (or a positive diagnosis, depending on the intervention class) distributes a nested intervention (the Config option) or an event will be broadcast which may trigger other interventions in the campaign file (the Event option). Possible values are:

  • Event
  • Config
{
    "Event_Or_Config": "Config"
}
Dont_Allow_Duplicates boolean NA NA 0 If an individual’s container has an intervention, set to true (1) to prevent them from receiving another copy of the intervention. Supported by all intervention classes.
{
    "Dont_Allow_Duplicates": 0
}
Disqualifying_Properties string NA NA NA A list of IndividualProperty key:value pairs that cause an intervention to be aborted (persistent interventions will stop being distributed to individuals with these values). See NodeProperties and IndividualProperties parameters for more information. Generally used to control the flow of health care access. For example, to prevent the same individual from accessing health care via two different routes at the same time.
{
    "Disqualifying_Properties": [
        "InterventionStatus:LostForever"
    ]
}
Intervention_Name string NA NA NA The optional name used to refer to this intervention as a means to differentiate it from others that use the same class.
{
    "Intervention_Name":"Diagnostic_Sample"
}
New_Property_Value string NA NA NA An optional IndividualProperty key:value pair that will be assigned when the intervention is distributed. See NodeProperties and IndividualProperties parameters for more information. Generally used to indicate the broad category of health care cascade to which an intervention belongs to prevent individuals from accessing care through multiple pathways. For example, if an individual must already be taking a particular medication to be prescribed a new one.
