State and Territory collections
State-based Data Linkage Units conduct separate probabilistic linkages with ALSWH cohorts (see ALSWH linked data sources for details of the collections and organisations involved).
Each State and Territory dataset is distinct in terms of its content (more information about state collections may be found on the PHRN website).
See ALSWH metadata for details of state/territory holdings, by cohort.
ALSWH only receives a selection of variables from any given collection. While we attempt to align variables across jurisdictions, we are limited not only by what is actually collected, but also by what is offered to external projects. In addition, not all state collections include records from private hospitals. Refer to the ALSWH Linked Data Variable Request Form for details of all collections.
Available for all states and all cohorts. Not all collections include private hospital records (ACT, NT and Tasmanian collections only cover nominated public hospitals).
All four ALSWH cohorts are linked. Currently available for ACT, NSW and WA (data for other jurisdictions is expected in 2020). Public hospitals only are included, with limited coverage of public hospitals in ACT, NSW, NT and Tasmania. Available for all cohorts.
Maternal Perinatal data are linked for the 1989-95 and 1973-78 Cohorts. They are available for all states, and cover all births, wherever they occur, except for ACT (records are from a single public hospital) and NT (records from private facilities are only included from 2014 on). Please note that due to specific legislative constraints, only women who have expressly consented to health record linkage are included in the Victorian Perinatal Data Collection (i.e. almost all of the 1989-95 Cohort, and 70% of the 1973-78 Cohort).
