Available projects

  • ORION: Leveraging Big Data to Inform Nationwide Cardiovascular Health Outcomes

    The Observing Recurrent Incidence of Adverse Outcomes following HospitalisatioNs (ORION) is a national data linkage study that brings together a decade of cardiovascular hospitalisation data from all Australian States and Territories and New Zealand. Encompassing millions of healthcare records from more than 1000 public and private facilities, ORION allows population-wide assessment of important end results of hospital-based cardiovascular care and understand how these outcomes vary among the many healthcare facilities and regions. Multiple projects suitable for HDR students are available focusing on the national epidemiology of common and rare cardiovascular conditions.

  • Safety, Effectiveness of care and Resource use among Australian Hospitals (SAFER Hospitals)

    Modern hospital care is fast-paced, complex and expensive. While this has undoubtedly led to better treatments, global concerns exist about the safety and effectiveness of hospital care. The SAFER Hospitals study is a nationwide study that seeks to address this limitation by bringing together linked hospitalisation and outcome data for all public and most private hospitals in Australia. Funded by a Translational Project Grant from the Hospital Research Foundation, SAFER Hospitals will estimate the hospital-wide incidence of serious adverse events, deaths and unplanned hospitalisations following hospital care and how these outcomes vary among hospitals. It will also evaluate the downstream impact by estimating the avoidable costs of these untoward outcomes on the health system.
