Australian health policies related to diagnostic imaging: too much of a good thing?

Diagnostic imaging is increasingly being used in Australia to aid clinician diagnostic and therapeutic decision-making. There is concern that this increased use represents an overconsumption of inappropriate health services, which wastes finite resources and may cause direct or indirect harm to the patient. Australian health policies have primarily focused on increasing patient access to diagnostic imaging. While these policies address inequitable access and may lead to timely diagnosis and improved health outcomes, these benefits have not been weighed against the unintended harms. This perspective article will explore the unintended consequences of increasing access to diagnostic imaging as well as provide potential solutions to improve the effectiveness of policies in this area.
