INTRODUCTION: Intestinal ultrasound (IUS) is a non-invasive, accurate, and increasingly utilized tool for the assessment and monitoring of inflammatory bowel disease (IBD).
OBJECTIVES: This Australian survey, endorsed by the Gastroenterology Network of Intestinal Ultrasound (GENIUS), aimed to evaluate clinician attitudes toward IUS and identify barriers to its broader national implementation.
DESIGN: National cross-sectional observational study.
METHODS: An online survey was distributed to adult and pediatric gastroenterologists and trainees across Australia, with data collected between September and December 2024.
RESULTS: One hundred twenty-two respondents participated, comprising adult (52%), pediatric (25%), and trainee (23%) gastroenterologists, with two-thirds reporting a subspecialty interest in IBD. Nearly all agreed that IUS has clinical utility in Crohn's disease (99%) and ulcerative colitis (96%), with 96% considering IUS standard of care in IBD. Clinical confidence in IUS was high (84%), particularly among IBD specialists (95% vs 73%; p < 0.01), though lower than for colonoscopy (98%) and magnetic resonance enterography (MRE; 97%). IUS was also perceived as more resource-efficient than colonoscopy (96%) and MRE (88%). While 82% of respondents had access to IUS, mainly in an outpatient capacity, availability was lower in non-metropolitan locations. Among clinicians without access, almost all agreed that IUS access would improve IBD care; with scarcity of IUS funding and trained personnel cited as barriers. Almost half of the respondents had completed or were undertaking IUS training, with 40% of remaining respondents interested in future training.
CONCLUSION: Australian gastroenterologists widely support IUS in IBD care. Expanding access to IUS requires renewed focus on service development and training initiatives, particularly in underserved areas, and cost-effectiveness studies to support these efforts.
