Field Length:  1

This is a field calculated by the computer. It does not appear on the abstract form. However, it is a patient level field that is available for analysis and reporting purposes.

It is calculated from the latest survival status entered for a patient. If Item 31760 (Survival Status) is 1, 2, or 3, then the value in this field is "1" (Alive); if Item 31760 is 4, 5, 6, or 9, then the value in this field is "0" (Dead).

At the central registry, this field may also be assigned through linkages with authoritative sources of vital status information such as Kentucky death certificates or the United States National Death Index.
