Abstract
This chapter focuses on the description of key commonalities and distinctions across encounter databases, illustrated with selected examples and supplemented by references to more comprehensive resources in the literature. It includes a dedicated discussion of the considerations faced by researchers when evaluating the appropriateness of a specific encounter database or deciding among multiple encounter databases for their research question. Encounter databases in South Korea, Taiwan and Australia all use Anatomical Therapeutic Chemical codes to identify individual medicines and all but Taiwan use ICD-10 codes to identify diagnoses. This allows for comparisons of similar products across different countries without the need to map individual country-specific codes. Encounter databases have a number of strengths in comparison to other data sources for pharmacoepidemiologic research, which explain their broad representation in the literature. Encounter databases are primarily intended and maintained for payment or other administrative purposes, and therefore are subject to important limitations when used for research.
