Description
Always exclude unavailable meals and optionally declined meals from a positive denominator, then divide attended by opportunities.
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.
Always exclude unavailable meals and optionally declined meals from a positive denominator, then divide attended by opportunities.
When to use this tool
Use Eldercare Meal Participation Denominator when you need a descriptive calculation on supplied geriatric research records.
How to use the tool and how it works
- Enter scheduledMeals, attendedMeals, declinedMeals, unavailableMeals, excludeDeclined. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read opportunities, participation. Use the output convention below.
Require positive scheduledMeals and compatible nonnegative attended, declined, and unavailable counts. Always exclude unavailable meals and optionally declined meals from a positive denominator, then divide attended by opportunities.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| scheduledMeals | Scheduled Meals | Required. Safe integer; minimum 1. |
| attendedMeals | Attended Meals | Required. Safe integer; minimum 0. |
| declinedMeals | Declined Meals | Required. Safe integer; minimum 0. |
| unavailableMeals | Unavailable Meals | Required. Safe integer; minimum 0. |
| excludeDeclined | Exclude Declined | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| opportunities | Opportunities | Required. Safe integer. |
| participation | Participation | Required. Finite number. |

}Limitations and assumptions
- Declining is distinct from unavailability; this is participation accounting without measuring intake, nutritional status, swallowing safety, or care adequacy.
- 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.
