Research output of radiologists in Australia and New Zealand: Strengths, weaknesses and future directions.

INTRODUCTION: Clinical radiology is a popular career. However, academic radiology in Australia and New Zealand (ANZ) has not traditionally been a strength of the specialty which has a focus on clinical medicine and has been influenced by corporatisation of the specialty. The aim of this study was to review the source(s) of radiologist-led research in Australia and New Zealand, to identify areas of relative deficiency and propose plans to improve research output. METHODS: A manual search was performed of all manuscripts in seven popular ANZ journals, where the corresponding or senior author was a radiologist. Publications between January 2017 and April 2022 were included. RESULTS: There were 285 manuscripts from ANZ radiologists during the study period. This equates to 10.7 manuscripts per 100 radiologists based on RANZCR census data. Radiologists in Northern Territory, Victoria, Western Australia, South Australia and the Australian Capital Territory all produced manuscripts above the corrected mean incidence rate of 10.7 manuscripts per 100 radiologists. However, locations including Tasmania, New South Wales, New Zealand and Queensland were below the mean. The majority of manuscripts arose from public teaching hospitals with accredited trainees (86%), and there were a higher proportion of manuscripts published by female radiologists (11.5 compared to 10.4 per 100 radiologists). CONCLUSION: Radiologists in ANZ are academically active; however, interventions aimed at increasing output could be targeted at certain locations and/or areas within a busy private sector. Time, culture, infrastructure and research support are vital, but personal motivation is also extremely important.

Radiologists' perspectives about evidence-based medicine and their clinical practice: a semistructured interview study.

OBJECTIVES: To describe radiologist's attitudes and perspectives on evidence-based medicine (EBM) and their practice. DESIGN: Face-to-face semistructured interviews, thematic analysis. SETTING: 24 institutions across six Australian states and New Zealand. Transcripts were imported into HyperRESEARCH software and thematically analysed. PARTICIPANTS: 25 radiologists. RESULTS: Six themes were identified: legitimising decisions (validated justification, prioritising patient preferences, reinforcing protocols), optimising outcomes (ensuring patient safety, maximising efficiency), availability of access (requiring immediacy, inadequacy of evidence, time constraints, proximity of peer networks, grasping information dispersion), over-riding pragmatism (perceptibly applicability, preserving the art of medicine, technical demands), limited confidence (conceptual obscurity, reputation-based trust, demands constant practice, suspicion and cynicism), and competing powers (hierarchical conflict, prevailing commercial interests). CONCLUSIONS: Radiologists believe EBM can support clinical decision-making for optimal patient outcomes and service efficiency but feel limited in their capacities to assimilate and apply EBM in practice. Improving access to evidence, providing ongoing education and training supplemented with practical tools for appraising evidence; and developing evidence-based guidelines and protocols may enhance feasibility and promote the confidence and skills among radiologists in applying EBM in radiology practice for better patient care.
