Description
Measure signed calendar days since recorded equipment cleaning.
Occupational-therapy records preserve the user's stated roles, goals, assistance and task context. Time shares and normalized preferences depend on their declared denominator or scale, while prompt counts are observations rather than measures of independence by themselves. Device geometry and loan balances need verified source records before broader interpretation.
Measure signed calendar days since recorded equipment cleaning.
When to use this tool
Use OT Equipment Cleaning Gap when you already have lastCleaningDate, asOfDate and need to measure signed calendar days since recorded equipment cleaning.
How to use the tool and how it works
- Enter lastCleaningDate, asOfDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedDaysSinceCleaning. Use the output convention below.
Parse real UTC YYYY-MM-DD dates; return asOfDate-lastCleaningDate in days.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| lastCleaningDate | Last Cleaning Date | Required. Text; maximum UTF-16 length 8192. Real proleptic Gregorian YYYY-MM-DD; four-digit years 0000-9999 accepted. |
| asOfDate | As Of Date | Required. Text; maximum UTF-16 length 8192. Real proleptic Gregorian YYYY-MM-DD; four-digit years 0000-9999 accepted. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedDaysSinceCleaning | Signed Days Since Cleaning | Required. Finite number. |

},

}
}Limitations and assumptions
- A future cleaning date gives a negative gap; no cleanliness, infection control, safe use or suitable cleaning interval is verified.
- 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.
Alternative or Complementary methods
Review the original activity record, client-stated priorities and assessment instrument for a substantive assessment. Inspect actual devices and inventory when fit, condition or availability matters; scalar offsets and record counts preserve narrower facts.
