Data from a number of aged care programs and the National Death Index (NDI) were linked to create the PIAC link map. It covers aged care assessments, use of key aged care service programs and deaths from 1 July 1997 to 30 June 2014. The link map  allows for person‑based analyses of aged care program use over time—also termed ‘pathways’—and how people’s patterns of use vary depending on particular factors.

The link map includes data on assessments conducted under the Aged Care Assessment Program (ACAP) and data on the following other aged care programs: residential aged care (permanent and respite); home-based aged care packages (Community Aged Care Packages (CACP), Extended Aged Care at Home (EACH) and Extended Aged Care at Home—Dementia (EACHD), and the Home Care Packages Program (HCP) which replaced these earlier 3 programs in August 2013); Transition Care Program (TCP); and Home and Community Care (HACC). Deaths data are from the NDI (September 2015 update).

PIAC 2014 contains a PIAC person identifier which acts as a link key between records in the National Aged Care Data Clearinghouse (NACDC) tables and the NDI. In addition, tables with preferred demographics and a list of service use events have been derived for each PIAC person ID.
