title: Buying best value health care: Evolution of purchasing among Australian private health insurers.
abstract: Since 1995 Australian health insurers have been able to purchase health services pro-actively through negotiating contracts with hospitals, but little is known about their experience of purchasing. This paper examines the current status of purchasing through interviews with senior managers representing all Australian private health insurers. Many of the traditional tools used to generate competition and enhance efficiency (such as selective contracting and co-payments) have had limited use due to public and political opposition. Adoption of bundled case payment models using diagnosis related groups (DRGs) has been slow. Insurers cite multiple reasons including poor understanding of private hospital costs, unfamiliarity with DRGs, resistance from the medical profession and concerns about premature discharge. Innovation in payment models has been limited, although some insurers are considering introduction of volume-outcome purchasing and pay for performance incentives. Private health insurers also face a complex web of regulation, some of which appears to impede moves towards more efficient purchasing.
