Neurologic manifestations of COVID-19 in critically ill patients: results of the prospective multicenter registry PANDEMIC.

BACKGROUND: Neurologic manifestations are increasingly reported in patients with coronavirus disease 2019 (COVID-19). Yet, data on prevalence, predictors and relevance for outcome of neurological manifestations in patients requiring intensive care are scarce. We aimed to characterize prevalence, risk factors and impact on outcome of neurologic manifestations in critically ill COVID-19 patients. METHODS: In the prospective, multicenter, observational registry study PANDEMIC (Pooled Analysis of Neurologic DisordErs Manifesting in Intensive care of COVID-19), we enrolled COVID-19 patients with neurologic manifestations admitted to 19 German intensive care units (ICU) between April 2020 and September 2021. We performed descriptive and explorative statistical analyses. Multivariable models were used to investigate factors associated with disorder categories and their underlying diagnoses as well as to identify predictors of outcome. RESULTS: Of the 392 patients included in the analysis, 70.7% (277/392) were male and the mean age was 65.3 (SD ± 3.1) years. During the study period, a total of 2681 patients with COVID-19 were treated at the ICUs of 15 participating centers. New neurologic disorders were identified in 350 patients, reported by these centers, suggesting a prevalence of COVID-19-associated neurologic disorders of 12.7% among COVID-19 ICU patients. Encephalopathy (46.2%; 181/392), cerebrovascular (41.0%; 161/392) and neuromuscular disorders (20.4%; 80/392) were the most frequent categories identified. Out of 35 cerebrospinal fluid analyses with reverse transcriptase PCR for SARS-COV-2, only 3 were positive. In-hospital mortality was 36.0% (140/389), and functional outcome (mRS 3 to 5) of surviving patients was poor at hospital discharge in 70.9% (161/227). Intracerebral hemorrhage (OR 6.2, 95% CI 2.5-14.9, p < 0.001) and acute ischemic stroke (OR 3.9, 95% CI 1.9-8.2, p < 0.001) were the strongest predictors of poor outcome among the included patients. CONCLUSIONS: Based on this well-characterized COVID-19 ICU cohort, that comprised 12.7% of all severe ill COVID-19 patients, neurologic manifestations increase mortality and morbidity. Since no reliable evidence of direct viral affection of the nervous system by COVID-19 could be found, these neurologic manifestations may for a great part be indirect para- or postinfectious sequelae of the infection or severe critical illness. Neurologic ICU complications should be actively searched for and treated.

Changes in demographic and diagnostic spectra of patients with neurological symptoms presenting to an emergency department during the COVID-19 pandemic: A retrospective cohort study

Objective: To analyse the characteristics of patients with neurological complaints seeking evaluation in an interdisciplinary emergency department (ED) during the rise of the COVID-19 pandemic in Germany. Methods: In this retrospective study, data on the number of ED presentations due to neurological complaints in weeks 1-15/2020 were collected. In addition, hospital chart data of patients referred for neurological evaluation during weeks 12-15/2020 when the pandemic began impacting on public life in Germany were analysed regarding demographic information, chief complaints, modes of presentation and disposition and ED discharge diagnosis. Both data sets were compared to respective periods from 2017. Results: During the surge of COVID-19, we found a significant decrease of the total number of neurological ED patients by 47.6%. Comparing weeks 12-15 of 2017 and 2020, we found a decrease in the number of patients of < 30 years (p < 0.001) and an increase of those >= 70 years (p < 0.001). A higher proportion of patients were admitted to escalated care (p = 0.03), and fewer patients were discharged against medical advice (p<0.001). In addition, the ratio of less acute diagnoses (eg, benign headaches) declined significantly. Conclusion: Our findings suggest that the pandemic has contributed to a-potentially transient-reframing of laypeople's perception of urgency and necessity for emergency presentation. The establishment and promotion of health-care structures and services like telemedical consultations and the creation of safe ED environments will be essential to enable adequate delivery of care in potential future waves of the pandemic.

Decreased admissions and change in arrival mode in patients with cerebrovascular events during the first surge of the COVID-19 pandemic.

BACKGROUND AND PURPOSE: Investigating clinical characteristics of patients presenting with cerebrovascular events during the pandemic may provide valuable insight into further understanding the phenomenon of decreased stroke admissions during the COVID-19 pandemic. METHOD: Data of patients presenting with a cerebrovascular event to the emergency department during weeks 12-17/2020 were compared to data from the respective weeks in 2019. RESULTS: A significant reduction in the number of admissions by 35.9% (p = 0.005) was observed during the COVID-19 epoch. In addition, significantly more patients arrived by ambulance during the COVID-19 epoch (2019: 75.7%, 2020: 94.2%; p = 0.001). CONCLUSION: Our data may have implications as to how campaigns raising awareness for serious medical conditions in the context of the pandemic should be framed.

Negative Impact of the COVID-19 Pandemic on Admissions for Intracranial Hemorrhage.

Background: The COVID-19 pandemic has seriously impacted healthcare systems worldwide. Admissions for various non-COVID-19 emergencies have significantly decreased. We sought to determine the impact of COVID-19 on admissions for intracranial hemorrhage to a German University Hospital emergency department. Methods: In a retrospective analysis of admissions to the emergency department of the University Hospital Mannheim from January to June 2020 and the corresponding time period in 2019, all patients admitted for either traumatic or non-traumatic intracranial hemorrhage were evaluated. Poisson regression was performed to analyze changes in admission rates as a function of year, epoch (COVID-19-epoch, March to April 2020 and corresponding months 2019; non-COVID-19-epoch, January to February and May to June 2019/2020) and the interaction of year and epoch (reflecting the impact of the pandemic and subsequent lockdown measures). Results: Overall, 320 patients were included in the study. During the COVID-19-epoch, admission rates for spontaneous intracranial hemorrhage decreased significantly by 42.1% (RR 0.579, p = 0.002, 95% confidence interval 0.410-0.818). Likewise, admission rates for traumatic intracranial hemorrhage decreased significantly by 53.7% [RR = 0.463, p < 0.001, 95% confidence interval (CI) 0.358-0.599]. Conclusion: The decrease of spontaneous intracranial hemorrhages may be a consequence of underutilization of the healthcare system whereas decreasing rates of traumatic intracranial hemorrhage admissions may predominantly reflect a decrease in true incidence rates due to lockdown measures with restricted mobility. Raising patient awareness to seek emergency healthcare for acute neurological deficits during lockdown measures is important to ensure appropriate emergency care for patients with intracranial hemorrhage.

Acute Stroke in Times of the COVID-19 Pandemic: A Multicenter Study.

BACKGROUND AND PURPOSE: This study aims to assess the number of patients with acute ischemic cerebrovascular events seeking in-patient medical emergency care since the implementation of social distancing measures in the coronavirus disease 2019 (COVID-19) pandemic. METHODS: In this retrospective multicenter study, data on the number of hospital admissions due to acute ischemic stroke or transient ischemic attack and numbers of reperfusion therapies performed in weeks 1 to 15 of 2020 and 2019 were collected in 4 German academic stroke centers. Poisson regression was used to test for a change in admission rates before and after the implementation of extensive social distancing measures in week 12 of 2020. The analysis of anonymized regional mobility data allowed for correlations between changes in public mobility as measured by the number and length of trips taken and hospital admission for stroke/transient ischemic attack. RESULTS: Only little variation of admission rates was observed before and after week 11 in 2019 and between the weeks 1 and 11 of 2019 and 2020. However, reflecting the impact of the COVID-19 pandemic, a significant decrease in the number of admissions for transient ischemic attack was observed (-85%, -46%, -42%) in 3 of 4 centers, while in 2 of 4 centers, stroke admission rates decreased significantly by 40% and 46% after week 12 in 2020. A relevant effect on reperfusion therapies was found for 1 center only (thrombolysis, -60%; thrombectomy, -61%). Positive correlations between number of ischemic events and mobility measures in the corresponding cities were identified for 3 of 4 centers. CONCLUSIONS: These data demonstrate and quantify decreasing hospital admissions due to ischemic cerebrovascular events and suggest that this may be a consequence of social distancing measures, in particular because hospital resources for acute stroke care were not limited during this period. Hence, raising public awareness is necessary to avoid serious healthcare and economic consequences of undiagnosed and untreated strokes and transient ischemic attacks.

Decreased utilization of mental health emergency service during the COVID-19 pandemic.

During the rapid rise of the COVID-19 pandemic, a reduction of the numbers of patients presenting to emergency departments has been observed. We present an early study from a German psychiatric hospital to assess the dynamics of mental health emergency service utilization rates during the COVID-19 pandemic. Our results show that the numbers of emergency presentations decreased, and a positive correlation between these numbers and mobility of the general public suggests an impact of extended measures of social distancing. This finding underscores the necessity of raising and sustaining awareness regarding the threat to mental health in the context of the pandemic.
