Proof of Concept 1

In-hospital and post-discharge mortality: learning about quality of care using data linkages from Australian States (PoC #1)

Chief Investigator/s: Ms Diana Rosman, Associate Professor Katrina Spilsbury
Institution: Curtin University
Funding Agency: Commonwealth Department of Industry, Innovation, Climate Change, Science, Research and Tertiary Education (DIICCSRTE) and the Western Australian Department of Commerce.
Data sets requested:
  • Hospital Morbidity Data Collection (WA)
  • Mortality Register (WA)
  • RBDM Deaths Registrations (NSW, Qld, SA)
  • ABS Mortality Data (NSW)
  • Admitted Patient Data Collection (NSW)
  • Hospital Admitted Patient Data Collection  (Qld)
  • Integrated South Australian Activity Collection (SA)
Jurisdictions involved:
  • WA
  • NSW
  • Qld
  • SA
Data Linkage Unit (s) involved: CHeReL; WADLB; SA-NT DataLink; Qld Health Research Linkage Group; and CDL
PHRN Services used: SUFEX
Project Completion date: June 2013
Project description:

The PHRN infrastructure will provide de-identified data about Australian residents who were discharged from a public or private hospital for an acute inpatient episode of care in WA, NSW and QLD and SA during the period 2004-05 to 2007-08.  Linked mortality data will also be sourced from the four participating jurisdictions for the 12-month period following hospitalisation.

The project serves the dual purpose of developing and testing the data acquisition and linkage processes needed to support ongoing multistate research of this kind, and to demonstrate the value of these linkages in informing a public health issue of national importance mortality during or within 30 days of an inpatient hospitalisation. The epidemiological aims of this project are consistent with the Australian Commission on Safety and Quality in Health Care (ACSQHC) program of work to develop national indicators for hospital mortality.
