#251 Profiling non-major trauma attended by the national ambulance service in 2020 and 2021

<h3>Introduction</h3> Each year, the National Ambulance Service (NAS) attends many patients who receive a working diagnosis of trauma but do not meet the full inclusion criteria for the Major Trauma Audit (MTA), hereafter referred to as non-major trauma. This study aims to profile the key characteristics of patients who experience non-major trauma. <h3>Methods</h3> We analysed data from the HRB-funded TRAUMA project, which uses combined data from the MTA and NAS electronic Patient Care Reports (ePCR) for 2020 and 2021. We analysed patients with a working diagnosis of trauma who do not subsequently appear in the MTA using descriptive statistics. <h3>Results</h3> Based on NAS ePCR data, approximately 42,000 patients in 2020 and 46,000 in 2021 received a working diagnosis of non-major trauma. Of these patients, 48.5% are female with an average age of 61.2 years (SD 26.0), and 51.5% are male, with an average age of 49.2 years (SD 25.5). The most common mechanism of injury was a fall, accounting for 36% of patients, followed by motor vehicle incidents, which accounted for 8% of patients. In total 87.7% of patients were transported to hospital by NAS following a non-major trauma incident, with the most common destinations being: Cork University Hospital (10.0%), University Hospital Limerick (9.5%) and Our Lady of Lourdes Hospital Drogheda (8.1%). <h3>Conclusion</h3> Our findings reveal a significant number of trauma cases nationally that require a pre-hospital response but do not meet the inclusion criteria for the MTA. Further analysis will demonstrate the profile of individuals that require a pre-hospital response for non-major trauma. Results are limited by the absence of data from the Dublin Fire Brigade, which handles a significant portion of trauma incidents in Dublin.
