AgeDiagnostic

The AgeDiagnostic intervention class identifies the age threshold of individuals. The minimum and maximum age ranges are configured (for example, 0-5 and 5-20), and the event is based on the resulting age of the individuals. This intervention should be used in conjunction with StandardInterventionDistributionEventCoordinator.

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
Event string NA NA NA The user-defined name of the diagnostic event.
{
    "class": "AgeDiagnostic",
    "Age_Thresholds": [{
        "Low": 0,
        "High": 15,
        "Event": "AgeMeasured0"
    }]
}
High float 0 1000 NA The high end of the age grouping.

        "Low": 0,
        "High": 15,
        "Event": "AgeMeasured0"
    }]
}
Low float 0 1000 NA The low end of the age grouping.

        "Low": 0,
        "High": 15,
        "Event": "AgeMeasured0"
    }]
}
Age_Thresholds array of JSON objects NA NA NA Used to associate age ranges for individuals.
{
    "class": "AgeDiagnostic",
    "Age_Thresholds": [{
        "Low": 0,
        "High": 15,
        "Event": "AgeMeasured0"
    }]
}
Base_Sensitivity float 0 1 1 The sensitivity of the diagnostic. This sets the proportion of the time that individuals with the condition being tested receive a positive diagnostic test. When set to 1, the diagnostic always accurately reflects the condition. When set to zero, then individuals who have the condition always receive a false-negative diagnostic test.
{
    "Base_Sensitivity": 0.8
}
Base_Specificity float 0 1 1 The specificity of the diagnostic. This sets the proportion of the time that individuals without the condition being tested receive a negative diagnostic test. When set to 1, the diagnostic always accurately reflects the lack of having the condition. When set to zero, then individuals who do not have the condition always receive a false-positive diagnostic test.
{
    "Base_Specificity": 0.9
}
Cost_To_Consumer float 0 3.40E+3 1 The unit ‘cost’ assigned to the diagnostic. Setting Cost_To_Consumer to zero for all other interventions, and to a non-zero amount for one intervention, provides a convenient way to track the number of times the intervention has been applied in a simulation.
{
    "Cost_To_Consumer": 0.333
}
Days_To_Diagnosis float 0 3.40E+3 0 The number of days from test until diagnosis.
{
    "Days_To_Diagnosis": 0.0
}
Treatment_Fraction float 0 1 1 The fraction of positive diagnoses that are treated.
