Description
Separate a supplied staff-handover overlap from an uncovered gap.
Emergency records distinguish event clocks, retrospective entry times, equipment dates, encounter identifiers and recorded triage or laboratory states. A supplied time gap is not a verified performance measure, and a recorded seal expiry does not establish equipment readiness. Simulation duty fractions and role labels describe training records rather than emergency-care instructions.
Separate a supplied staff-handover overlap from an uncovered gap.
When to use this tool
Use Emergency Staff Handover Overlap Minute when you already have outgoingEndMinute, incomingStartMinute and need to separate a supplied staff-handover overlap from an uncovered gap.
How to use the tool and how it works
- Enter outgoingEndMinute, incomingStartMinute. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read overlapMinutes, uncoveredMinutes. Use the output convention below.
Return max(0,outgoingEnd-incomingStart) as overlap and max(0,incomingStart-outgoingEnd) as uncovered minutes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| outgoingEndMinute | Outgoing End Minute | Required. Finite number. |
| incomingStartMinute | Incoming Start Minute | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| overlapMinutes | max(0,outgoingEnd-incomingStart), using two supplied boundaries only. | Required. Finite number. |
| uncoveredMinutes | Uncovered Minutes | Required. Finite number. |

}Limitations and assumptions
- Only two boundary times are used; actual shift durations, coverage, roles, staffing adequacy and safe handover are not checked.
- 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
Review the actual event, equipment and laboratory records with verified timing and the complete clinical workflow. Treat local flags and interval arithmetic as record checks; they do not supply triage, response protocols, safe staffing or an assessment of a real emergency.
