Epidemiology of trauma presentations to a major trauma centre in the North West of England during the COVID-19 level 4 lockdown

PURPOSE: The COVID-19 pandemic has impacted healthcare systems globally, little is known about the trauma patterns during a national lockdown. The aim of this study is to delineate the trauma patterns and outcomes at Aintree University Teaching Hospital level 1 Major Trauma Centre (MTC) during the COVID-19 lockdown imposed by the U.K. government. METHODS: A retrospective cohort study data from the Merseyside and Cheshire Trauma Audit and Research Network database were analysed. The 7-week ‘lockdown period’ was compared to a 7-week period prior to the lockdown and also to an equivalent 7-week period corresponding to the previous year. RESULTS: A total of 488 patients were included in the study. Overall, there was 37.6% and 30.0% reduction in the number of traumatic injuries during lockdown. Road traffic collisions (RTC) reduced by 42.6% and 46.6%. RTC involving a car significantly reduced during lockdown, conversely, bike-related RTC significantly increased. No significant changes were noted in deliberate self-harm, trauma severity and crude mortality during lockdown. There was 1 mortality from COVID-19 infection in the lockdown cohort. CONCLUSION: Trauma continues during lockdown, our MTC has continued to provide a full service during lockdown. However, trauma patterns have changed and departments should adapt to balance these alongside the COVID-19 pandemic. As the U.K. starts its cautious transition out of lockdown, trauma services are required to be flexible during changes in national social restrictions and changing trauma patterns. COVID-19 and lockdown state were found to have no significant impact on survival outcomes for trauma.
