Abstract:
|
The primary objective of the Accuracy of Cancer Mortality as Measured by Death Certificates study was to estimate agreement between the cancer site listed in the cancer registry and the cancer site listed on the death certificate. Records from California, Colorado, and Idaho Central Cancer Registries were linked with state vital statistics data. A retrospective analysis compared death certificate data from 2002--2004 to cancer registry diagnoses from 1993--2004 (confirmation rate) and a prospective study design compared diagnoses reported in the cancer registry from 1993--1995 to death certificate data from 1993--2004 (detection rate). Wide variation in the rates was observed by study design and cancer site. Potential confounding by ICD version and time from diagnosis to death were investigated. Analyses were conducted to examine patterns of misclassification among the nonmatching cases.
