Australia has had some success at utilizing Health Technology Assessment (HTA) to disinvest and reassess medical services. This has been achieved through a range of methods including identifying services through initiatives such as ‘Choosing Wisely’, examining real world service data and seeking expert clinical opinion. This presentation will discuss how better international collaboration in disinvestment and reassessment methods using HTA could lead to more efficient health care systems.

Both the Australian and South Korean governments have a particular interest in disinvestment and reassessment in their health care systems. These countries have been sharing information over the past two years with a common goal of improving their health systems through a rigorous reassessment process. The Australian Government is in the process of reviewing all publicly funded services utilizing expert clinical committee advice, often referring the reassessment of services to a HTA process. A similar process is also being undertaken in South Korea.

Australia has disinvested in a wide range of services using HTA, including hip arthroscopy, lipectomy and hyperbaric oxygen therapy. It is also undertaking an extensive reassessment of 5,700 services. Reassessment may not lead to HTA, but it often includes an examination of whether a service should be subjected to HTA to remain publicly funded. Australia and South Korea have similar approaches in undertaking disinvestment and reassessment. HTA disinvestment and reassessment strategies have generated good outcomes for consumers, health care providers and funders in both countries.

Disinvestment and reassessment of medical services require funders that support the continual improvement of health care systems. Disinvestment and reassessment HTA can be difficult, mainly due to external interests - an issue experienced by many countries. Further international collaboration in this area may provide a more supportive environment to undertake HTA for disinvestment.
