Arterial catheters (ACs) are widely used in intensive care units (ICUs) for continuous blood pressure monitoring and frequent blood sampling. However, their use varies significantly, and concerns exist about potential risks such as infection, thrombosis, and unnecessary procedures. This study uses the RAND/UCLA Appropriateness Method to assess the clinical appropriateness of arterial catheter use in adult ICU patients across a range of clinical scenarios. By integrating the best available evidence with expert consensus, we aim to provide clearer guidance on when ACs are most likely to benefit patients.
Our findings will inform clinical decision-making, support guideline development, and help reduce unwarranted variation in practice. This research contributes to improving patient safety, enhancing resource use, and promoting evidence-based care in critical care settings.
This study is supported by the Royal Brisbane and Women’s Hospital Foundation and Queensland University of Technology.
Led by Professor Samantha Keogh, this study forms part of a broader research program focused on optimising arterial catheter use and improving patient outcomes.
