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. WebObjectives To assess validity of record linkage using multiple indirect personal identifiers to identify same-patient hospitalisations and definition of episode of care (EC) due to acute coronary syndrome (ACS). Methods Using national hospital discharge data to identify all admissions due to ACS, we used six different linkage rules using indirect identifiers with …
