Description
Check an observation's time against a supplied death boundary and equality convention.
Health-economic accounting distinguishes evaluation perspective, reference years, utility tariffs, timing and allocated costs. Missing resource use differs from measured zero, and a caller-supplied weight differs from a validated model correction. One cost or budget contribution does not establish cost effectiveness or an appropriate allocation of care.
Check an observation's time against a supplied death boundary and equality convention.
When to use this tool
Use Utility Observation Death Boundary Tag when checking the stated supplied health-economic record, timing or allocation convention.
How to use the tool and how it works
- Enter observationTime, suppliedDeathTime, boundaryCountsAsAfter. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read afterBoundary. Inspect afterBoundary before interpreting the associated values.
Compare observationTime with suppliedDeathTime. afterBoundary means strictly later, including equality only when boundaryCountsAsAfter=true.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observationTime | Observation Time | Required. Finite number. |
| suppliedDeathTime | Supplied Death Time | Required. Finite number. |
| boundaryCountsAsAfter | Boundary Counts As After | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| afterBoundary | After Boundary | Required. Boolean. |

}Limitations and assumptions
- Time coordinates are supplied and may be signed; no death record, mortality outcome or appropriate utility convention is inferred.
- 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 a complete justified economic model, verified sources and qualified health-economic/financial assessment for real policy or care-allocation decisions.
