IntroductionThe STUMBL Score clinical prediction model was originally developed and externally validated to support clinical decision-making of patients with blunt chest wall trauma in the Emergency Department. The aim of this scoping review was to understand the extent and type of evidence in relation to the STUMBL Score clinical prediction model as a component of the management of patients with blunt chest wall trauma managed in the Emergency Care setting.MethodsA systematic search was conducted across databases, including Medline, Embase and the Cochrane Central Register of Controlled Trials from Jan 2014 to Feb 2023. In addition, a search of the grey literature was undertaken along with citation searching of relevant studies. Published and non-published sources of all research designs were included. Data extracted included specific details about the participants, concept, context, study methods and key findings relevant to the review question. Data extraction followed the JBI guidance and results presented in tabular format accompanied with a narrative summary.ResultsA total of 44 sources originating from eight countries were identified, 28 were published and 16 grey literature. Sources were grouped into four separate categories: 1) external validation studies, 2) guidance documents, 3) practice reviews and educational resources 3) research studies and quality improvement projects, 4) grey literature unpublished resources. This body of evidence describes the clinical utility of the STUMBL Score and has identify how the score is being implemented and used differently in different settings including analgesic selection and participant eligibility for including in chest wall injury research studies.DiscussionThis review demonstrates how the STUMBL Score has evolved from solely predicting risk of respiratory complications to a measure which supports clinical decision making for the use of complex analgesic modes and as a guide for eligibility in chest wall injury trauma research studies. Despite external validation of the STUMBL Score, there is a need for further calibration and evaluation, particularly relating to these repurposed functions of the score. Overall, the clinical benefit of the score remains clear and its wide usage demonstrates the impact it has on clinical care, patient experience and clinician decision making.Copyright © 2023 Elsevier Ltd.
