Abstract
The Canadian Cancer Registry (CCR) is a longitudinal person-oriented database containing all the information on cancer patients and their tumours registered in Canada since 1992. The information at the national level is provided by the Provincial and Territorial Cancer Registries (PTCRs). An important aspect of the CCR is the Death Clearance Module (DCM). It is a system that is designed to use the death records from the Canadian Mortality Data Base to confirm the deaths of the CCR patients that occurred during a pre-specified period. After extensive preprocessing, the DCM uses a direct match approach to death confirm the CCR patients that had a death registration number on their record and it performs a probabilistic record linkage between the remaining CCR patients and death records. For one province, death registration numbers are not provided with the cancer patient records. All these records go directly to the probabilistic linkage. For the rest of the country, a good proportion of the cancer patients reported as dead by the PTCRs have such a number that can be used to match directly the two databases. After an overview of the CCR and its DCM, this presentation will compare the situation where the direct match is used in conjunction with the probabilistic linkage to death confirm cancer patients versus the case where the probabilistic record linkage is used alone.
