Background: Clinical registries are pivotal for advancing patient care and clinical research. The prospective Point of Care Ultrasound Registry (PURE) is a unique, pioneering initiative that aims to accumulate essential ultrasound data through a dedicated collection tool. This study investigates user satisfaction with the implementation of PURE, a first-of-its-kind registry, focusing on a spectrum of implementation outcomes.

Methods: Using a cross-sectional survey approach, this study evaluated diverse implementation metrics such as acceptability, appropriateness, adoption, accessibility, feasibility, efficacy and efficiency. Statistical analyses were conducted to determine the overall user satisfaction with the implementation of this novel registry.

Results: The study yielded a mean implementation score (IS) of 3.83 (95% CI 3.59–4.07). Effectiveness (E) had a mean score of 1.93 (95% CI 1.80–2.05) and Cumulative Implementation Factor (A) averaged 1.90 (95% CI 1.78–2.03). Notably, 11 of the 30 participants achieved an IS above 4, with a predominant 21 of 30 surpassing an IS of 3.8. Nevertheless, the scores for efficiency and feasibility, registered at 0.392/0.625 and 0.165/0.250, respectively, indicate areas for improvement.

Conclusion: While PURE represents an innovative step forward in point-of-care ultrasound (POCUS) data collection, its initial implementation did not fully resonate with user satisfaction expectations. Significant possibilities for enhancement lie particularly within the efficiency and feasibility sectors. To improve its utility, measures such as optimising the data collection tool, bolstering training programmes, merging with existing systems, and implementing thorough evaluation and feedback processes are recommended. A nuanced understanding of the time pressure faced by anaesthetists during data input can provide valuable insights into further areas of potential refinement.
