BackgroundDuring March 2020 the country was plunged into a nationwide lockdown. Despite this, there remained a steady stream of trauma admissions. COVID changed a lot about how many medical specialties worked and we wanted to explore the effects on our patient population, and compare it to the experience of other hospitals. MethodsWe analysed existing data on admissions to the Emergency Department that were referred to the trauma service between the 12th of March to the 24th of May; encompassing the lockdown and the two weeks either side. This data was compared to that of the year beforehand. We compared ages, sexes, mortality, methods of injury, and disposition.ResultsAdmissions fell, 193, compared to 271 (∼3:1 M:F). Both cohorts featured more younger people, but there was a drop-off in the number of older folk post-COVID; 6 of 9 centiles of the over 60s showed a fall in admissions of at least 14%. Those admitted to the Major Trauma service (ISS 9+) remained the same. Regarding the methods of injury, the most common presentations remained road traffic accidents, stabbings and falls <1m, contributing to 71 and 72% total admissions before and after COVID respectively. However, there were fewer patients falling from heights of > 2m (OR 0.5), and fewer recorded assaults (OR 4.0). Penetrating injuries were separated into “stabbings” and “others”. There was a significant increase in non-stabbing penetrating injuries (OR 4.6), a majority of which were self-inflicted. The rate of self harm during the lockdown showed a similar increase, from featuring in 8% of total presentations to 15% of admissions (OR 1.87). The hospital restructured considerably between the sample dates such that dispositions are not possible to compare meaningfully. Rates of patients sent straight home from the ED were similar (OR 1.0).ConclusionsOverall, the lockdown had a moderate impact on patient numbers and demography. The data implies that the measures did small amounts to deter people from the roads and from interacting with each other in assaults and stabbings. Older people were less likely to present traumatically. The isolation may have led to a masking of mental health issues leading to a significant increase in self harm, which may present opportunities for restructuring of services in any the event of further major lockdowns. These conclusions are limited by the data, and next steps would include gathering more detailed mortality data.
