Abstract

The development of a generalized iterative record linkage system for use in follow-up of cohorts in epidemiologic studies is described. The availability of this system makes such large-scale studies feasible and economical. The methodology for linking records is described as well as the different modules of the computer system developed to apply the methodology. Two applications of record linkage using the generalized system are discussed together with some considerations regarding strategies for conducting linkages efficiently.
