Many injured patients receive urgent CT imaging to identify major injury. CT imaging of trauma patients is often time critical and the accurate detection of life-threatening findings on this CT is essential. Often following a scan a radiologist is not immediately available to review the imaging, however other members of the trauma team have access to the imaging and may be in a position to provide a "hot" report. In this study we aim to demonstrate if an educational intervention with a checklist improves accuracy of the hot report.

This is a randomised controlled trial to evaluate whether a standardised approach, educational package (with checklist) may improve recognition of major life-threatening injuries in the hot reporting of trauma scans. A pilot study with 20 participants allocated to the two groups on 1:1 ratio which will receive the education package, will inform feasibility of the larger study.

The larger study will recruit 300 participants, 100 on each group on 1:1:1 ratio, to evaluate the primary objective.

Participants will be clinicians who volunteer to participate in an online educational package. Participant data will be collected by the online platform under a unique identifier. Results will then be extracted from the platform and then associated with the demographic data on the trust system.

Following application of inclusion and exclusion criteria, participants will be allocated into one of three groups, and assigned a participant number. The test data set will consist of cases that have been pseudo anonymised with the key stored on trust systems.

Inclusion Criteria:

• Medical professionals involved in trauma image review.
• This includes clinicians who are emergency department doctors, radiologists and other specialties.
• Non-radiologist clinicians will be participating completing the hot reports, radiologists will be evaluating their submissions and assessing their accuracy.

Exclusion Criteria:

• Unable to review CT imaging due to lack of previous experience or disability that prevents them from doing so.
• Under 18 years old.
• Not a medical professional or clinician.

We aim to make IPD available after the project's 1st publication with the data analysed. We anticipate that this will be a maximum of one year following the anticipated completion date of the project, 15th January 2028.

The IPD and supporting information will be made available via the request process outlined below after the project's first publication with the data analysed. We anticipate this will be a maximum of one year following the anticipated completion date of the study (15th January 2027).

Requests for data sharing can be made after publication of the primary results paper. Requests should be made to the Chief Investigator in the first instance. Requesters will be asked to complete an application form detailing specific requirements, rationale, and proposed usage. The CI and study sponsor (including the sponsor's Research Governance Manager (or deputy), the Information Governance Team, Calidcott Guardian, IM&T Security Officer and the researcher funder, as appropriate) will review all requests.

Consideration will be given to:

1. The viability and suitability of the request
2. Appropriate steps have been taken to minimise the risk of identifying participants
3. Data security policies and procedures of recipient organisation (including country if abroad) and other regulatory requirements are applicable
4. The credentials of the requestor

Where access to requested data is granted, requesters organisation must sign a data sharing agreement before they can access any

Each Group will not be aware of the intervention or education or content the other Group receives.
