Description
In requireAll mode, a known false component resolves the rule as false and all known true components resolve it as true; otherwise it remains unknown.
Case-definition records combine criteria, knowledge flags, document versions and date applicability. A component can be unknown rather than false, and literal agreement with supplied rules is separate from independent clinical classification.
In requireAll mode, a known false component resolves the rule as false and all known true components resolve it as true; otherwise it remains unknown.
When to use this tool
Use Case Definition Component Flag when checking a stated rule, its known components or its supplied version interval.
How to use the tool and how it works
- Enter componentSatisfied, componentKnown, requireAll. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read definitionKnown, meetsRule. Inspect definitionKnown, meetsRule before interpreting the associated values.
Require equally long, nonempty componentSatisfied and componentKnown arrays. In requireAll mode, a known false component resolves the rule as false and all known true components resolve it as true; otherwise it remains unknown. In any-component mode, one known true resolves true, all known false resolves false, and other cases remain unknown. Return definitionKnown and meetsRule; meetsRule is false whenever the rule remains unknown.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| componentSatisfied | Component Satisfied | Required. Array of boolean; maximum items 256. |
| componentKnown | Component Known | Required. Array of boolean; maximum items 256. |
| requireAll | Require All | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| definitionKnown | Whether known components determine the requested all/any rule. | Required. Boolean. |
| meetsRule | Rule result when determined; false placeholder when definitionKnown is false. | Required. Boolean. |

}Limitations and assumptions
- A false meetsRule must be interpreted with definitionKnown. Unknown components do not become negative observations. These boolean rules do not select clinical criteria, establish case status independently or handle weighted definitions.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Review the authoritative case definition and original records; local boolean or version checks cannot establish the completeness or suitability of the definition.
