Comparative Analysis of COVID-19 Outbreak and Changes in Neurosurgical Emergency Patients

Epidemiology and Outcomes of Severe Traumatic Brain Injury: Regional Trauma Center in Incheon, Korea, 2018-2022

Objective

This study aims to explore the epidemiology and outcomes of severe traumatic brain injury (TBI) in Incheon, focusing on regional characteristics using data from a local trauma center.

Methods

From January 2018 to December 2022, 559 patients with severe TBI were studied. We analyzed factors related to demography, prehospitalization, surgery, complications, and clinical outcomes, including intensive care unit stay, ventilator use, hospital stay, mortality, and Glasgow outcome scale (GOS) scores at discharge and after 6 months.

Results

In this study, most severe TBI patients were in the 60-79 age range, constituting 37.4% of cases. Most patients (74.1%) used public emergency medical services for transportation, and 75.3% arrived directly at the hospital, a significantly higher proportion compared to transferred patients. Timewise, 40.0% reached the hospital within an hour of injury. Complication rates stood at 16.1%, with pneumonia being the most common. The mortality rate was 44.0%, and at discharge, 81.2% of patients had unfavorable outcomes (GOS 1-3), reducing to 70.1% at 6 months.

Conclusion

As a pioneering study at Incheon's trauma center, this research provides insights into severe TBI outcomes, enhancing understanding by contrasting local and national data.

The Impact of The COVID-19 Pandemic on Hospital Admissions Due to Road Traffic Crashes; a Systematic Review and Meta-Analysis

Introduction

During the unprecedented COVID-19 lockdowns, road traffic was limited, and a change in the traumatic emergency admission pattern was anticipated. We conducted the current systematic review and meta-analysis to assess the impact of the COVID-19 pandemic on hospital admissions due to road traffic crashes.

Methods

This systematic review and meta-analysis was conducted based on the Joanna Briggs Institute (JBI) instructions. The following databases were searched: PubMed, ISI Web of Knowledge, Scopus, ProQuest, and the Cochrane Library. Two independent reviewers screened articles based on the inclusion criteria for the review and assessed the methodological quality of the included studies using an appropriate appraisal checklist, introduced by the JBI, based on the study type. The meta-analysis was performed using Comprehensive meta-analysis (CMA) software. Considering the heterogeneity among studies, a random effect model was adopted to estimate the pooled effect with 95% confidence interval (CI) for binary outcomes.

Results

A total of 13 studies were included in this systematic review, and all of them were considered for meta-analysis. According to the meta-analysis, differences in hospital admission rates during the COVID-19 pandemic and one year before this pandemic were statistically significant [RR: 0.685 CI 95% (0.578 -0.813) p<0.00001]. The heterogeneity assessment of the included studies in the meta-analysis showed high heterogeneity (I2=78%, p<0.00001).

Conclusion

The results of this systematic review showed that the COVID-19 pandemic dramatically reduced the number of hospital admissions related to road traffic crashes because of both quarantines and lifestyle changes. Health policymakers and top health managers might use the results of this systematic review in similar contexts in the future.

The Effect of the COVID-19 Pandemic and Lockdown on Operative Traumatic Brain Injury in Northern Virginia

INTRODUCTION

COVID-19 is a disease that causes flu-like symptoms and difficulty breathing. Emerging in 2019, the COVID-19 pandemic has affected the entire world through restrictions and lockdowns. Multiple studies have compared the effects of COVID-19 on different types of head trauma, with each one producing different results. The goal of this study was to use state and hospital data to determine whether the COVID-19 pandemic had a significant impact on surgeries for traumatic brain injury (TBI).

METHODS

Public state data on COVID-19 incidence, sourced from the Virginia Department of Health, was compared to hospital data of 352 patients receiving surgeries for TBI from a single major level-one trauma hospital in Northern Virginia. We used data from the three years before COVID-19 and the two years during the pandemic, using t-tests and Pearson correlation to analyze the data. This is a retrospective case review study on the number and age of patients receiving TBI surgery from March 2017 through February 2022 at Inova Fairfax Hospital in Northern Virginia to determine the impact of the COVID-19 pandemic on these factors.

RESULTS

When comparing the data, there was a 60% reduction in cases of operative TBI during the peak months of COVID-19 compared to the same months in previous years (p<0.005). Comparing data on the number of Virginia and Northern Virginia COVID-19 cases and data on the age of individuals undergoing TBI surgery four weeks later showed a statistically significant negative correlation (p<0.05) in which the average age of individuals undergoing TBI surgery was lower in the four-week block following a four-week block of increased COVID-19 incidence.

CONCLUSION

Our findings indicate a correlation between the period of decreased activity from COVID-19 restrictions in Virginia and a decline in both the number of TBI surgeries and the age of individuals undergoing these surgeries.

The Direction of Neurosurgery to Overcome the Living with COVID-19 Era : The Possibility of Telemedicine in Neurosurgery

OBJECTIVE

Due to the implementation of vaccinations and the development of therapeutic agents, the coronavirus disease 2019 (COVID-19) pandemic that started at the end of 2019 has entered a new phase. As a result, neurosurgeons should reconsider the way they treat their patients. As the COVID-19 situation prolongs, the change in neurosurgical emergency patients according to the number of confirmed cases is no longer clear. Outpatient treatment by telephone was permitted according to government policy. In addition, visits to caregivers in the intensive care unit were limited.

METHODS

The electronic medical records of patients who had been treated over the phone for a month (during April 2020, while the hospital was closing) were reviewed. Meanwhile, according to the limited visits to the intensive care unit, a video meeting was held with the caregivers. After the video meeting, satisfaction was evaluated using a questionnaire.

RESULTS

During April 2020, 1021 patients received non-face-to-face care over the telephone. Among the patients, no critical medical problem occurred due to non-face-to-face care. From July 2021 to December 2021, 321 patients were admitted to the neurosurgical intensive care unit and 107 patients (33.3%) including their caregivers agreed to video visits. Twice a week, advance notice was given that access would be made through a mobile device and the nurse explained to caregivers how to use the mobile device. The time for the video meeting was approximately 20 minutes per patient. Based on the questionnaire, 81 respondents (75.7%) answered that they agreed, and 26 respondents (24.3%) answered that they strongly agreed that was easy to communicate through video meetings. Fifty-two (48.6%) agreed and 55 (51.4%) strongly agreed that they were easy to understand the doctor's explanation. For overall satisfaction with this video meeting, three respondents (2.8%) gave 4/5 points and 95 respondents (88.8%) gave 5/5 points, and nine (8.4%) gave 3/5 points. Their reason was that there was not enough time.

CONCLUSION

In situations where patient visits are limited, video meetings through a mobile device can provide sufficient satisfaction to caregivers. Telemedicine will likely become common in the near future. Health care professionals should prepare and respond to these needs and changes. Therefore, establishing a system with institutional support is necessary.

The impact of the COVID-19 pandemic on surgical education: A survey and narrative review

Background

Since the emergence of the COVID-19 pandemic, medical education has been a concerning issue, especially in surgical fields. Due to the postponement of many elective surgeries and even alternations in the pattern of emergent surgeries, concerns have been raised about whether residents of surgical disciplines are experienced enough after graduation or not. We aimed to describe the impact of the COVID-19 pandemic on surgical residency training in different fields.

Materials and methods

We conducted a cross-sectional study with a 20-item questionnaire on residents of surgical disciplines from three different educational hospitals of Tehran University of Medical Sciences, Iran in 2020. In addition, we reviewed the current literature regarding the impact of COVID-19 pandemic on surgical education worldwide.

Results

Our survey, with a response rate of 56.8% demonstrated significant reduction in the time spent in elective surgeries, surgical clinics and even in emergent surgeries for residents. Besides, it has reported that significant time has been spent in COVID 19 wards which resulted in decreased satisfaction of educational activities.

Conclusions

The impacts of COVID 19 pandemic on surgical education are significant and inevitable. Thus, we must integrate novel educational methods in surgical curriculum to optimize training and minimize the adverse effects of the pandemic on surgical education.

A Nationwide Study on the Impact of COVID-19 Pandemic on Volume of Spine Surgery in South Korea

OBJECTIVE

In March 2020, World Health Organization declared a global pandemic caused by a novel coronavirus (SARS-CoV-2). The disease caused by this virus is called COVID-19. Due to its high contagiousness, many changes have occurred in overall areas of our daily life including hospital use by patients. The aim of this study was to investigate the impact of COVID-19 on volume of spine surgery in South Korea using the National Health Insurance database and compare it with the volume of a homologous period before the pandemic.

METHODS

Data of related to spine surgery from January 2019 to April 2021 were obtained from the National Health Insurance and Health Insurance Review and Assessment Service database. Primary outcomes were total number of patients, rate of patients per 100000 population, and total number of procedures. The number of patients by hospital size was also analyzed.

RESULTS

COVID-19 outbreaks occurred in South Korea in March, August, and December of 2020. Compared to the previous year, the total number of patients who underwent spinal surgery showed a decrease for 2-3 months after the first and second outbreaks. However, it showed an increasing trend after the third outbreak. The same pattern was observed in terms of the ratio of the number of patients per 100000 population. Between 2019 and 2021, the mean number of spine surgeries per month tended to increase. Mean annual medical expenses increased over the years (p=0.001). When the number of spine surgeries was analyzed by hospital size, proportion of tertiary general hospital in 2021 increased compared to those in 2019 and 2020 (vs. 2019, p=0.012; vs. 2020, p=0.016). The proportion of general hospital was significantly decreased in 2020 compared to that in 2019 (p=0.037).

CONCLUSION

After the COVID-19 outbreak, patients tended to postpone spinal surgery temporarily. The number of spinal surgeries decreased for 2-3 months after the first and second outbreaks. However, as the ability to respond to the COVID-19 pandemic at the hospital and society-wide level gradually increased, the number of spine surgeries did not decrease after the third outbreak in December 2020. In addition, the annual number of spine surgeries continued to increase. However, it should be noted that patients tend to be increasingly concentrated in tertiary hospitals for spinal surgery.

COVID-19 and Ventricular Shunt Revisions

Introduction: COVID-19 patients frequently experience headaches, malaise, and fatigue. For patients with shunted hydrocephalus, these signs and symptoms can often be indicative of shunt failure. Thus, it can be challenging to determine if shunt failure has occurred in this patient population. Therefore, we explored the question of how a diagnosis of COVID-19 in shunted hydrocephalus patients influences the rate of shunt revision.

Methods: We used a deidentified database network (TriNetX) to gather information on patients with shunted hydrocephalus and COVID-19 versus no COVID-19 from January 20, 2020, through September 26, 2021. Our primary outcome of interest was shunt revision at 90 days, with secondary outcomes of mortality, hospitalization, ICU admission, mechanical ventilation, tracheostomy, PEG tube placement, fall, seizure, acute kidney injury (AKI), venous thromboembolism (VTE), ischemic stroke (I.S.), myocardial infarction (MI), and sepsis. Cohorts were propensity score-matched for common comorbidities and demographics.

Results: After propensity score matching, 10,600 patients with shunted hydrocephalus and COVID-19 (cohort 1) and 10,600 patients with shunted hydrocephalus and no COVID-19 (cohort 2) were identified. Average age was 38.5 years. Eight hundred and thirty-four patients (7.869%) in cohort 1 and 180 (1.698%) patients in cohort 2 underwent shunt revision (p=<0.0001, OR 4.978, 95% CI 4.198, 5.821). Mortality was 4.642% vs. 2.113% (p<0.0001, OR 2.255, 95% CI 1.921, 2.647). Hospitalization rates were 27.72% vs. 10.303% (p<0.0001), and ICU admission rates 11.567% vs. 3.463% (p<0.0001). Ventilator dependence was 3.529% vs. 0.953% (p<0.0001), tracheostomy 1.142% vs. 0.236% (p<0.0001), PEG tube insertion 2.472% vs. 0.585% (p<0.0001), falls 2.321% vs. 1.076% (p<0.0001), seizure 11.369% vs. 5.953% (p<0.0001), AKI 4.416% vs. 1.717% (p<0.0001), VTE 3.538% vs. 1.293% (p<0.0001), sepsis 3.887% vs. 1.179% (p<0.0001), IS 0.585% vs. 0.16% (p<0.0001), and MI 1.34% vs. 0.519% (p<0.0001).

Conclusion: COVID-19 infection is associated with an almost five-fold increase in shunt revisions.
