Using non-disclosive computerised linkage we combined Scottish breast screening and Census 2001 data.
Incident cases of colorectal cancer and deaths from all causes were ascertained, respectively, by means of computerised record linkages to the Canadian Cancer Database and to the National Mortality Database.
Incident cases of renal cell cancer and deaths from all causes were ascertained, respectively, by means of computerised record linkages to the Canadian Cancer Database and to the National Mortality Database, both of which are maintained by Statistics Canada.
Incident cases of breast, endometrial, ovarian, colorectal, and lung cancer and deaths from all causes were ascertained respectively by means of computerised record linkages to the Canadian Cancer Database and to the National Mortality Database.
All primary cancers before or after the index breast cancer were ascertained through a computerised record linkage method.
An alternative method of obtaining health outcome data for cohort studies is computerised record linkage [ 11, 12].
Computerised record linkage offers a passive and ongoing method of obtaining health outcomes from existing routinely collected data sources.
A study comparing the accuracy of ascertaining mortality through computerised record linkage with CMDB found 96.4% completeness, equivalent to high-quality manual searches (Shannon et al, 1989).
Cases of incident endometrial cancer and deaths were ascertained respectively through computerised record linkage to the Canadian Cancer Database and the National Mortality Database, both of which are maintained by Statistics Canada.
We ascertained the incidence of lung cancer through a computerised record linkage to the Miyagi Prefecture Cancer Registry, one of the oldest and most accurate population-based cancer registries in Japan (Takano and Okuno, 1997).
