Ninety Day Mortality

DD_category: 
PUF Data Item Name: 
PUF_90_DAY_MORT_CD
length: 
1
Allowable values: 
0, 1, 9
Description: 
This item indicates mortality within 90 days after the most definitive primary site surgery.
Analytic Note: 

The computation was based on the Date of Most Definitive Surgical Resection of the Primary Site (NAACCR #3170) if that was known.  Otherwise, it was based on the Date of First Surgical Procedure (NAACCR Item #1200).  In either case, the Date of Last Contact or Death (NAACCR Item #1750) was subtracted from the surgery date and patient Vital Status (NAACCR Item #1760) indicated whether the latter date referred to contact or death. Eligible cases are limited to Surgical Procedure of the Primary Site codes 20-90 (NAACCR Item #1290). Ninety Day Mortality is blank for patients diagnosed in 2013. Investigators analyzing surgical mortality at the facility level must use the Surgery of the Primary Site at this Facility variable (item RX_HOSP_SURG_PRIM_SITE) to determine if the surgery was performed at the facility included in the PUF data. See the Getting Started document for more information.

Thirty Day Mortality

DD_category: 
PUF Data Item Name: 
PUF_30_DAY_MORT_CD
length: 
1
Allowable values: 
0, 1, 9
Description: 
This item indicates mortality within 30 days of the most definitive primary site surgery.
Analytic Note: 

The computation was based on the Date of Most Definitive Surgical Resection of the Primary Site (NAACCR Item #3170) if that is known.  Otherwise, it was based on the Date of the First Surgical Procedure (NAACCR Item #1200). In either case, the Date of Last Contact or Death (NAACCR Item #1750) was subtracted from the surgery date and patient Vital Status (NAACCR Item #1760) indicated whether the latter date referred to contact or death. Eligible cases are limited to Surgical Procedure of the Primary Site codes 20-90 (NAACCR Item #1290). Thirty Day Mortality is blank for patients diagnosed in 2013. Investigators analyzing surgical mortality at the facility level must use the Surgery of the Primary Site at this Facility variable (item RX_HOSP_SURG_PRIM_SITE) to determine if the surgery was performed at the facility included in the PUF data.

PUF Vital Status

DD_category: 
PUF Data Item Name: 
PUF_VITAL_STATUS
NAACCR Item #: 
1760
length: 
1
Allowable values: 
0, 1
Description: 
Records the vital status of the patient as of the date entered in Date of Last Contact or Death (NAACCR Item #1750), which is the status of the patient at the end of Elapsed Months - Date of Diagnosis to Date of Last Contact or Death in the PUF.
Analytic Note: 

Vital Status is blank for cases diagnosed in 2013.  See "Getting Started" for an explanation about calculating survival for cases diagnosed recently.
 
Vital Status is the only item for which SEER and CoC agreed to retain different codes to mean the same thing.  For historic reasons, SEER uses code 4 for deceased patients while CoC uses 0.  All 4s in the CoC database were converted to 0 for the PUF file.  There is no Vital Status code for "unknown".  Therefore, cases for which the code was not valid are transmitted as blank.  They may have been submitted as blanks, 9s, or any other non-defined value.  They can be analyzed as "unknown" or omitted from analysis, depending on the needs of the study.

Registry Coding Instructions: 

None.

Analytic Note: 

Months Elapsed is blank for patients diagnosed in 2013.  See "Getting Started" for a discussion of survival calculations for patients diagnosed recently.
