WebMay 1, 2011 · Two frequently applied strategies in record linkage are deterministic record linkage (DRL) and probabilistic record linkage (PRL). In DRL, all or a predefined subset of linking variables have to agree (corresponding values on a linking variable are the same within a pair) to consider a pair as a link [7], [11], [12], [13]. WebMar 28, 2024 · Deterministic record linkage is a good option when the entities in the data sets have identified common identifiers with a relatively high quality of data.

WebDeterministic Matching • A series of common identifying fields are selected across two datasets – Records are matched based on these fields – Identical values across all these fields to be matched • Easiest, quickest linkage strategy • Ideal for some situations – Pre-existing common ID numbers WebDeterministic Linkage Methods. Deterministic algorithms determine whether record pairs agree or disagree on a given set of identifiers, where agreement on a given identifier is assessed as a discrete—“all-or-nothing”—outcome. Match status can be assessed in a single step or in multiple steps.

WebMar 25, 2024 · The “Deterministic record linkage” section discusses rule- and similarity-based approaches, which are popular due to their interpretability and scalability. The “Probabilistic record linkage” section introduces probabilistic record linkage methods that have led to many advancements and extensions. WebFor approach 1 (deterministic record linkage), we identified the initial potential FPs matches as those with discrepancies in full names between the patient and death record (largely due to situations where an individual had 2 last names or differences in middle name fields) (n = 14,906).
