Description
Include omissions in the denominator only when requested, divide assisted count when positive, otherwise return zero with defined false.
Geriatric research summaries organize supplied observations, activities, and support records. Counts and ratios describe that research data; they are not clinical scores unless an independently validated scoring method explicitly defines them.
Include omissions in the denominator only when requested, divide assisted count when positive, otherwise return zero with defined false.
When to use this tool
Use Questionnaire Assistance Item Share when you need a descriptive calculation on supplied geriatric research records.
How to use the tool and how it works
- Enter assistedItems, completedItems, omittedItems, includeOmitted. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominator, assistedShare, defined. Inspect defined before interpreting the associated values.
Require nonnegative completedItems, assistedItems within completed, and omittedItems. Include omissions in the denominator only when requested, divide assisted count when positive, otherwise return zero with defined false.1

| includeOmitted | Include Omitted | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominator | Denominator | Required. Safe integer. |
| assistedShare | Assisted Share | Required. Finite number. |
| defined | Whether the stated denominator or normalization exists; inspect before interpreting a zero placeholder. | Required. Boolean. |

}Limitations and assumptions
- The denominator policy changes the share; supplied assistance counts do not assess independent function, capacity, questionnaire validity, or care needs.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the appropriate validated assessment and professional review when clinical interpretation is required. Check observation scope, missingness, and denominator conventions before comparing research summaries.
