BackgroundRib fractures are associated with significant morbidity and mortality, and providing adequate analgesia is paramount in preventing early complications from these injuries. Multiple regional anaesthetic techniques can be used to provide analgesia for these injuries; however, few evidence-based guidelines exist for their use. The aim of this study was to establish consensus within an expert group on the selection criteria used when choosing regional anaesthetic techniques for rib fractures.MethodsThe Delphi technique is a mixed-methods study format which uses a longitudinal survey process to develop consensus opinion amongst an expert group. A three-round modified e-Delphi study was undertaken using an online survey platform. Round one established cohort characteristics and identified key factors considered important by the group when selecting regional anaesthetic techniques for rib fractures. Subsequent rounds used Likert scales and free text comments to rate the participants' level of agreement with various statements generated from the first-round responses. The final consensus threshold was established as at least 70% of respondents stating, 'Strongly Disagree' or 'Disagree' or alternatively 'Agree' or 'Strongly Agree'.ResultsAn expert panel of UK-based consultants in anaesthesia and/or intensive care medicine was recruited. Participants worked in a variety of tertiary- and non-tertiary trauma care settings and were varied in their years of experience, approximate annual rib fracture caseload and preference for various anaesthetic techniques in rib fracture management. 54 participants took part in round one and generated 60 statements which were further analysed in an iterative process involving a total of three rounds. A total of 28 statements ultimately reached the pre-defined threshold for consensus within the expert group.ConclusionsThis e-Delphi study succeeded in building consensus across multiple statements relating to the selection criteria for regional anaesthesia in patients with rib fractures. These consensus statements can inform clinical practice, guide future research priorities and can be integrated into decision-making pathways across multiple hospital settings.Copyright © 2023 Elsevier Ltd.
