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. What is known about the topic? When warranted, diagnostic imaging aids the diagnostic process by ruling in (or out) conditions that benefit from treatment and lead to improved patient outcomes. What does this paper add? This paper describes recent policies related to diagnostic imaging in Australia, discusses how increasing access may lead to unintended harms and create further inefficiencies in the system, and provides direction for future health policies in this area. What are the implications for practitioners? Addressing the inappropriate use of diagnostic imaging is crucial for the sustainability of the sector. [ABSTRACT FROM AUTHOR]
