Usage Notes

When to Use ContributingFactor

Use ContributingFactor when:

Within MultifactorialCondition — Always used as component of a MultifactorialCondition
Multiple causes interact — When explaining which factors contribute to an outcome
Importance varies — When some factors matter more than others
Treatment planning needed — When knowing modifiability guides intervention strategy

Importance Levels

Use consistent categorization:

Major — Factor is nearly always present and significantly contributes to the condition
Significant — Factor commonly contributes but condition can occur without it
Minor — Factor plays a supporting role or affects severity but isn't directly causal

Modifiability Values

Understanding Modifiability

true — Factor can be changed through intervention (e.g., diet, exercise)
false — Factor is fixed (e.g., genetics, age, past events)
"partial" — Factor can be influenced but not eliminated (e.g., stress can be reduced but not eliminated)

Focus treatment recommendations on modifiable factors while acknowledging non-modifiable factors for risk assessment.

Best Practices

Explain mechanisms — Always describe HOW the factor contributes
Quantify prevalence — Include data on how common this factor is
List interventions — Provide specific, actionable ways to address modifiable factors
Include distinguishing features — Help clinicians identify when this factor is present
Rate evidence — Be transparent about certainty level
Specify affected populations — Indicate what percentage experience this factor
