The Pathways in Aged Care (PIAC) link map is a data asset derived by linking aged care activity data from the National Aged Care Data Clearinghouse (NACDC) and death records from the National Death Index (NDI). It includes activity data for aged care assessments, home support, home care, transition care and residential aged care.

PIAC is suitable for person-based analysis of aged care pathways and patterns of program use over time. It links data from different aged care programs that do not use a common person identifier, enabling people’s care use to be tracked across services. Derived analysis data sets are available for recipient demographics, event sequence and service locations.
