ALLOWABLE VALUES

er285 Date Conclusive DX

A valid, complete date in YYYYMMDD.

General Date Editing Rules:

Date fields are recorded in the D1 date format of year, month, day (CCYYMMDD). Month and day must have leading zeros for values 01...09.

The following date format is allowed:

CCYYMMDD Century+Year, Month and Day are provided.

Dates are checked first to ensure they conform to one of these formats, then for errors in the components. Checking stops on the first non-valid situation.

Range Checking:

Lowest allowed value:  January 1, 1850 (or in D1 format: 18500101)

Highest allowed value: current system date

The month is checked to ensure it falls within range 01...12.

The day is checked to ensure it falls within range for that specific month. Accommodation is made for leap years.

SOURCE

If the record version is NAACCR version 12 (120 in original new case) or later, then upload the date and its associated flag value with no conversion.

Otherwise, if the record version is earlier than 12, then perform the following conversions in this order:

  1. Right-justify and zero-fill the date to 8 digits.

  2. Convert MMDDYYYY to YYYYMMDD.

  3. Convert Date Conclusive DX and Date Conclusive DX Flag in the same manner as described in the Eureka Process Specification:  2010 Data Conversions document.

If steps 1 and 2 are the only changes made to the date, then DO NOT record them in the audit log.

UPDATE

Tumor Level

New Case Consolidation

If the admission and tumor’s Date Conclusive DX or Date Conclusive DX Flag values are different, then

List both dates and both flags for review

Manual Update*, **

Admission Level

Manual Update or Correction Applied to date or associated date flag*, **

*If a full or partial date is entered in the date field, then automatically change the associated flag to blank; If a numeric associated flag code is selected/entered, then automatically change the date to blank

**If the date is changed, it is now later*** than Date of Last Contact, and Vital Status is alive(1), then automatically update Date of Last Contact with the new date and reset Date of Last Contact Flag to blank (this update applies to the patient’s Date of Last Contact and Vital Status for a Tumor Level change and to the patient and admission’s Date of Last Contact and Vital Status for an Admission level change).

*** With year, month, and/or day potentially blank, a completely known date could appear to be later because it is a larger number than a partial later date.  Thus, to test for the latest date among known full or partial dates, use these tests in this order:
