A cross‐sectional study assessing the role of interventional radiology services in regional and remote Australia

Abstract Introduction It is estimated that 8% of hospitalised patients require treatment from Interventional Radiology (IR). However, little is known about the potential impact of IR on regional and remote Australians, including Indigenous patients. This study aimed to assess treatments performed by IRs on regional/remote patients to predict future IR workforce and governance needs. Methods Single‐centre cross‐sectional study at a tertiary Victorian hospital. Patients were identified when they had an advanced IR treatment between 1 January 2022 and 2024. Basic procedures such as biopsy and drain insertion were not included. The primary outcome was the type and volume of IR treatments performed on patients who were transferred from a regional or remote home location for treatment. Results Of 3485 advanced IR interventions, 908 procedures (26.0%) from patients who lived in a regional or remote location were included with 36.5% female, of mean age 55.6 years (SD 17.9). 1.4% identified as Indigenous which is similar to the Indigenous population incidence in Victoria of 1.0%. Of this group, 350 (38.5%) were either a day procedure, overnight elective admission, or simple inpatient procedure which could have been performed in a regional centre, which included 1.1% Indigenous patients. Conclusion There is an unmet need for IR services in regional and remote Australia, with many patients being transferred to our metropolitan centre for treatment that could be performed in regional IR hubs. This data will be important to drive government and hospital planning including capital infrastructure, workforce modelling and future recognition of IR as a new specialty in Australia.
