About the research project

Many health conditions can be effectively managed and treated in primary and community health care. If this care is unavailable or not accessed, individuals may require hospital care that was avoidable. Such hospital admissions are referred to as Potentially Preventable Hospitalisations (PPHs), and are used as a proxy measure of the effectiveness of primary and community health care. Twenty-two health conditions have been identified by the Australian Commission on Safety and Quality in Health Care as PPHs.

In 2017/18, PPHs accounted for 1 in 15 hospital admissions and 1 in 10 hospital bed days nationally. For Tasmania, in 2016/17, there were 13,889 admissions and 52,469 bed days. PPHs can be reduced by improving access and availability of primary care and community health care services. In turn, reducing the number of PPHs would reduce the impact on Tasmanian public hospitals in relation to bed block and ambulance ramping  and will  provide better health outcomes for patients.

The aims of this study are to:

  • Characterise PPHs in Tasmania: age, gender, key diagnoses, geographical locations, patients with multiple PPH diagnoses, length of stay
  • Estimate the annual costs of PPH to the Tasmanian Health System
  • Geographically map areas of highest PPH rates and primary care/community health services to identify potential priority areas to improve early intervention/disease management
  • Work with stakeholders (patients, service providers, policy makers) to understand contextual issues relating to PPHs and to develop a strategic plan to reduce the number of PPHs.

The proposed PhD project will use linked data from the Tasmanian Admitted Patients Dataset and Emergency Department Dataset, along with National Health Services Directory. For aim 4, focus groups and 1:1  semi-structured interviews will be conducted. Please note part of this project is currently under review with the Royal Hobart Hospital Research Foundation (Project Grant, $25,000). This funding will be used to support a postdoctoral fellow who will drive project development in year 1. If this funding application is unsuccessful, the project will still go ahead, with the primary supervisor taking on a more active role in project development activities.
