Internationally, best practice for prison health care recommends transferring health service provision from corrections to health authorities. Although it is expected that this change will result in improved health care, there is little evidence of evaluation. This article used qualitative interviews with health service providers to gain insight into the health needs of women’s prisons in Queensland, Australia, both prior to and after the transition in health care service provision. We found that service providers identified that problems persisted regardless of service provider and that improvement required increased resources and more fundamental structural changes within prison environments.
