Description
Return visitDay-targetDay and positive excess of absolute deviation over tolerance.
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.
Return visitDay-targetDay and positive excess of absolute deviation over tolerance.
When to use this tool
Use Research Visit Window Deviation when you need a descriptive calculation on supplied geriatric research records.
How to use the tool and how it works
- Enter visitDay, targetDay, suppliedToleranceDays. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read deviationDays, outsideByDays. Use the output convention below.
Require nonnegative integer suppliedToleranceDays. Return visitDay-targetDay and positive excess of absolute deviation over tolerance.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| visitDay | Visit Day | Required. Safe integer. |
| targetDay | Target Day | Required. Safe integer. |
| suppliedToleranceDays | Supplied Tolerance Days | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| deviationDays | Deviation Days | Required. Safe integer. |
| outsideByDays | Outside By Days | Required. Safe integer. |

}Limitations and assumptions
- Day coordinates and visit allowance are supplied; no recommended visit schedule, medical urgency, protocol compliance, or patient safety is determined.
- 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.
