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 2014. 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.
