Quality of care was not compromised during the COVID-19 pandemic at a level 1 trauma centre

What effect did the New Zealand COVID-19 lockdown have on computed tomography-head scan utilisation in patients presenting to the emergency department with traumatic head injuries?

OBJECTIVES

To explore the unique impact the first COVID-19 national lockdown in New Zealand (NZ) had on the utility of computed tomography (CT)-head scanning in patients presenting to the ED with head injuries.

METHODS

Retrospective observational study of CT-head use in head-injured patients presenting to the ED during the 2020 COVID-19 lockdown compared to the corresponding time period in 2019.

RESULTS

During the lockdown period in 2020, the total number of ED presentations reduced by 30.3% (95% confidence interval [CI] 28.8-31.6) from 13 477 to 9403. The total number of head injury presentations also reduced by 32% (95% CI 27-36.7) from 523 to 356. The proportion of head-injured patients remained similar (3.9% [n = 523] in 2019 vs 3.8% [n = 356] in 2020). Of the head injured patients, 185 (51.9%, 95% CI 44.5-59.4) had CT-head scans performed in 2020 compared to 269 (51.4%, 95% CI 45.2-57.5) in 2019; a reduction of 31.2% (95% CI 24.5-37.9). The proportion of patients who had a CT-head scan remained similar (51.4% [95% CI 45.2-57.5] in 2019 vs 51.9% [95% CI 44.5-59.4] in 2020). There were no significant differences in the proportion of CT-head scans with acute traumatic pathology (13.0% [95% CI 8.7-17.3] in 2019 vs 12.4% [95% CI 7.4-17.5] in 2020, P = 0.86).

CONCLUSIONS

During the first COVID-19 lockdown in NZ, the total number of patients presenting to the ED decreased by one third. Reassuringly, the proportion of patients who presented with head injuries, had a CT-head scan performed, and had positive CT-head findings remained the same as the previous year.

Victoria's surgical response to the COVID-19 pandemic: the first two years

Victoria suffered three major waves during the first two years of the COVID-19 pandemic. Melbourne became the longest locked down city in the world at 267 days. This narrative review documents the chronological waves of COVID-19 in Victoria and key themes influencing the State-wide surgical response. In 2020, Victoria needed to secure supplies of personal protective equipment (PPE) and later, recognizing the importance of aerosol transmission, introduced a respiratory protection program to protect health care workers (HCWs) with fit-tested N-95 masks. It established routine preoperative PCR testing for periods when community prevalence was high and developed strategies to restrict elective surgery when hospital capacity was limited. In 2021, three short-term outbreaks were contained and eliminated whilst vaccination of HCWs and the vulnerable was taking place. A third major wave (Delta) occurred July to November 2021, succeeded by another involving the Omicron variant from December 2021. Planned surgery waiting list numbers, and waiting times for surgery, doubled between March 2020 and March 2022. In early 2022, almost 300 patients underwent surgery when infected with Omicron, with a low mortality (2.6%), though mortality was significantly higher in the unvaccinated (7.3% versus 1.4%). In conclusion, the Victorian response to COVID-19 involved tight state-wide social restrictions, contact tracing, furlough, escalating PPE guidance and respiratory protection. HCW infections were greatly reduced in 2021 compared with 2020. Pre-operative PCR testing gave confidence for emergency and urgent elective surgery to proceed during pandemic waves. Other elective cases were performed as health system capacity allowed, without compromising outcomes.

The Global Impact of COVID-19 on Solid Organ Transplantation: Two Years Into a Pandemic

The coronavirus disease 2019 (COVID-19) pandemic has had a major global impact on solid organ transplantation (SOT). An estimated 16% global reduction in transplant activity occurred over the course of 2020, most markedly impacting kidney transplant and living donor programs, resulting in substantial knock-on effects for waitlisted patients. The increased severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection risk and excess deaths in transplant candidates has resulted in substantial effort to prioritize the safe restart and continuation of transplant programs over the second year of the pandemic, with transplant rates returning towards prepandemic levels. Over the past 2 y, COVID-19 mortality in SOT recipients has fallen from 20%-25% to 8%-10%, attributed to the increased and early availability of SARS-CoV-2 testing, adherence to nonpharmaceutical interventions, development of novel treatments, and vaccination. Despite these positive steps, transplant programs and SOT recipients continue to face challenges. Vaccine efficacy in SOT recipients is substantially lower than the general population and SOT recipients remain at an increased risk of adverse outcomes if they develop COVID-19. SOT recipients and transplant teams need to remain vigilant and ongoing adherence to nonpharmaceutical interventions appears essential. In this review, we summarize the global impact of COVID-19 on transplant activity, donor evaluation, and patient outcomes over the past 2 y, discuss the current strategies aimed at preventing and treating SARS-CoV-2 infection in SOT recipients, and based on lessons learnt from this pandemic, propose steps the transplant community could consider as preparation for future pandemics.
