Abstract
Aims, Objectives and Background There is evidence that COVID-19 ‘lockdowns’ may have contributed to increased non-accidental injury, domestic violence and self-harm related to deteriorating mental health. Internationally, there is also evidence that the diversion of health care resources may led to worse outcomes for patients presenting with major trauma. There has been no previous national evaluation of ‘lockdown’ measures impact on the characteristics, treatment pathways and outcomes of trauma patients in England
We aimed to assess the impact of successive lockdowns on the volume, demographics, injury mechanism, severity, treatment and outcomes of major trauma in England.
Method and Design Demographic characteristics and clinical pathways of TARN eligible patients in the first lockdown (24th March to 3rd July 2020 inclusive) and second lock down (1st November 2020 to 16th May 2021 inclusive) were compared to equivalent pre-COVID-19 periods in 2018–2019.
A segmented regression model predicting the weekly risk adjusted survival was estimated and a discontinuity in the gradient (trend) or intercept (level) of the fitted model was tested for at the weekly time point of implementation of each lockdown.

Results and Conclusion The first ‘lockdown’ had a larger associated reduction in total trauma volume (-21%) compared to the pre-COVID period than the second ‘lockdown’ (-6.7%). Trauma volume increased for those 65 and over (3%) and 85 and over (9.3%) during the second ‘lockdown’.
There was a reduction in likelihood of survival (-1.71; 95% CI:-2.76 to -0.66) associated with the immediate introduction of the first ‘lockdown’. However, this was followed by a trend of improving survival (0.25; 95% CI: 0.14 to 0.35) and likelihood of survival returned to pre-pandemic levels by the end of the first ‘lockdown’ period.
Future research is needed understand the initial reduction in likelihood of survival after major trauma observed with the implementation of the first ‘lockdown’ to prevent this occurring if measures re-introduced.
