abstract: Comparability of cancer identification among death registry, cancer registry and hospital discharge registry - International Journal of Cancer

Abstract

Registry based cancer incidence and mortality data are widely used for etiologic research, cancer control and health care monitoring and planning. The complete coverage of all cases is the key criteria of data quality but it is difficult to assess because the alternative sources of data may be flawed. ..........

..........In conclusion, some 10% of cancer deaths had no cancer records in CR (cancer registry) or in HDR (hospital discharge registry), and 3.4% were missing in both sources. The identification rate depended on tumor site, age at death, and, to some extent, death outside hospital.
