er131 RX Date DX/Stg Proc

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 formats are allowed:

     CCYYMMDD Century+Year, Month and Day are provided.

     CCYYMM__ Century+Year and Month. Day consists of two blank spaces.

     CCYY____ Century+Year. Month and Day consist of four blank spaces.

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

     When month is known, it is checked to ensure it falls within range 01...12.

     When month and day are known, 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 RX Date DX/Stg Proc and RX Date DX/Stg Proc 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 any of the following conditions are true:

• The admission’s RX Date DX/Stg Proc date is fully known or partially known and the tumor’s RX Date DX/Stg Proc date is blank

• The admission and tumor’s RX Date DX/Stg Proc dates are both blank, but the admission’s RX Date DX/Stg Proc Flag value is higher according to this hierarchy: 12, 11, 10, blank

• Any part of the Tumor’s RX Date DX/Stg Proc date is blank, that same part of the Admission’s RX Date DX/Stg Proc date is entered, and other entered parts are equal

• All of the following conditions are true:

• The admission’s Class of Case = 10-22,

• the admission and tumor’s RX Date DX/Stg Proc dates are both fully known or partially known,

• the admission’s RX Date DX/Stg Proc is earlier**** than the tumor’s RX Date DX/Stg Proc, and RX Hosp--DX/Stg Proc = 01-07

Then automatically update the tumor’s RX Date DX/Stg Proc and RX Date DX/Stg Proc Flag values with the admission’s corresponding values

Manual Change*, **

Admission Level

Manual Change or Correction applied to date or its 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:

• If one of the known dates’ years is later than (greater than) the other date’s year being compared or if it is the only known year/date, then that date is the latest known date

• If multiple known dates have the same latest year, but only one of them has a latest known month, then that is the latest known date

• If multiple known dates have the same latest year & month, but only one of them has a latest known day, then that is the latest known date

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

• If one of the known dates’ years is earlier than (less than) the other known date’s year or if it is the only known year/date, then that date is the earliest known date

• If multiple known dates have the same earliest year, but only one of them has an earliest known month, then that is the earliest known date

• If multiple known dates have the same earliest year & month, but only one of them has an earliest known day, then that is the earliest known date
