Description
Measure signed charting delay after a supplied observation.
Nursing records connect observations, chart-entry times, handoff identifiers, device assignments and task status. A timestamp delay differs from verified retrospective documentation, and a matching identifier differs from an authenticated specimen or handoff. Time windows and due times must retain their stated boundary rules.
Measure signed charting delay after a supplied observation.
When to use this tool
Use Nursing Observation Charting Delay when you already have observationSeconds, chartEntrySeconds and need to measure signed charting delay after a supplied observation.
How to use the tool and how it works
- Enter observationSeconds, chartEntrySeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedDelaySeconds, retrospective. Inspect retrospective before interpreting the associated values.
Return chartEntrySeconds-observationSeconds; retrospective means chartEntry>observation.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observationSeconds | Observation Seconds | Required. Finite number. |
| chartEntrySeconds | Chart Entry Seconds | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedDelaySeconds | Signed Delay Seconds | Required. Finite number. |
| retrospective | True only for chartEntrySeconds>observationSeconds; equality is false. | Required. Boolean. |

}Limitations and assumptions
- Zero delay is not retrospective and negative delay is retained; timestamps do not establish actual observation, record accuracy or compliance.
- 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
Reconcile original chart, specimen and handoff records when identity or completion matters. Use the documented workflow and actual care context for task timing; a literal match or supplied time margin is only one local record check.
