“…Firstly, comparing the pre-COVID and intra-COVID period: we used the Mann-Whitney U test (17) to compare mean monthly rates, and test of proportions compared percentage of stroke requiring IVT or EVT. Secondly, Interrupted time series analysis was performed using the fpp3 package (18) to calculate β (absolute change in presentation rate), standard error, t value, and p-value using a previously published method (19). Interrupted time series analysis is a segmented regression approach to test an effect of an intervention on a timedependent outcome using a defined impact model.…”

“…Consecutive observations over time can tend to be more similar to closer months than further months, a phenomenon known as autocorrelation, and this violates the assumption of non-ITS regression models that observations need to be independent (21). Not many studies choose this advanced statistical approach to analyze the impact of COVID on service-level data, which highlights the methodological strength of our analysis (19,26,(31)(32)(33)(34)38).…”

Background and aimRapid outpatient evaluation and treatment of TIA in structured clinics have been shown to reduce stroke recurrence. It is unclear whether short-term downtrends in TIA incidence and admissions have had enduring impact on TIA clinic activity. This study aims to measure the impact of the pandemic on hospitals with rapid TIA clinics.MethodsRelevant services were identified by literature search and contacted. Three years of monthly data were requested – a baseline pre-COVID period (April 2018 to March 2020) and an intra-COVID period (April 2020 to March 2021). TIA presentations, ischemic stroke presentations, and reperfusion trends inclusive of IV thrombolysis (IVT) and endovascular thrombectomy (EVT) were recorded. Pandemic impact was measured with interrupted time series analysis, a segmented regression approach to test an effect of an intervention on a time-dependent outcome using a defined impact model.ResultsSix centers provided data for a total of 6,231 TIA and 13,191 ischemic stroke presentations from Australia (52.1%), Canada (35.0%), Italy (7.6%), and England (5.4%). TIA clinic volumes remained constant during the pandemic (2.9, 95% CI –1.8 to 7.6, p = 0.24), as did ischemic stroke (2.9, 95% CI –7.8 to 1.9, p = 0.25), IVT (−14.3, 95% CI −36.7, 6.1, p < 0.01), and EVT (0, 95% CI –16.9 to 16.9, p = 0.98) counts. Proportion of ischemic strokes requiring IVT decreased from 13.2 to 11.4% (p < 0.05), but those requiring EVT did not change (16.0 to 16.7%, p = 0.33).ConclusionThis suggests that the pandemic has not had an enduring effect on TIA clinic or stroke service activity for these centers. Furthermore, the disproportionate decrease in IVT suggests that patients may be presenting outside the IVT window during the pandemic – delays in seeking treatment in this group could be the target for public health intervention.

ObjectivesEver since COVID‐19, short‐term changes in transport injury patterns have been observed. The aim is to examine both the initial and the enduring impact of government lockdown and the pandemic on road injuries requiring hospitalisation and road fatalities.MethodsTime series analysis of Transport Accident Commission (TAC) claims involving hospitalisation and fatalities in Victoria, Australia, from July 2016 to May 2023, including lockdown (March 2020 to October 2020) and post‐lockdown (November 2020 onwards).ResultsA total of 46 450 TAC claims were included. Average claims during the pre‐pandemic period were 652/month. Lockdown restrictions were associated with a statistically significant fall in monthly claims (−255, 95% confidence interval [CI] = −315 to −194, P < 0.01). This was consistent across road users, days of the week, hours of the day, injury severity, sex and central versus rural locations. The post‐lockdown period had a statistically significant reduction in monthly claims to 76% (95% CI = 67–84) of pre‐pandemic levels (−158, 95% CI = −213 to −102, P <0.01). This was consistent across all subgroups except bicyclist injuries, which remained constant (−8, 95% CI = −16 to 0, P = 0.05). There was a significant upward trend in the fatality‐to‐claim ratio post‐lockdown (0.001, 95% CI = 0–0.001, P <0.01).ConclusionRoad injury requiring hospitalisation decreased significantly during governmental lockdown and has returned to three‐quarters of pre‐pandemic levels (except bicyclist injuries that have remained constant), but there is an increasingly disproportionate number of fatalities. This represents a new baseline of injury burden for EDs and hospitals that manage trauma patients.
