Northern Territory Cancer Register data quality, 1981-2001

Abstract

Indicators of completeness of case ascertainment and of data accuracy were assessed for the NTCR for cases diagnosed from 1981 (when the Registry commenced operation) to 2001. Data quality indicators were compared to indicators for other Australian cancer registries. Where possible, data quality was assessed separately for cancer registrations for indigenous and non-indigenous people. Several notification sources were re-screened to identify cases that had not been previously notified.
