Prevalence and Risk Factors of Neurologic Manifestations in Hospitalized Children Diagnosed with Acute SARS-CoV-2 or MIS-C.

BACKGROUND: Our objective was to characterize the frequency, early impact, and risk factors for neurological manifestations in hospitalized children with acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or multisystem inflammatory syndrome in children (MIS-C). METHODS: Multicenter, cross-sectional study of neurological manifestations in children aged <18 years hospitalized with positive SARS-CoV-2 test or clinical diagnosis of a SARS-CoV-2-related condition between January 2020 and April 2021. Multivariable logistic regression to identify risk factors for neurological manifestations was performed. RESULTS: Of 1493 children, 1278 (86%) were diagnosed with acute SARS-CoV-2 and 215 (14%) with MIS-C. Overall, 44% of the cohort (40% acute SARS-CoV-2 and 66% MIS-C) had at least one neurological manifestation. The most common neurological findings in children with acute SARS-CoV-2 and MIS-C diagnosis were headache (16% and 47%) and acute encephalopathy (15% and 22%), both P < 0.05. Children with neurological manifestations were more likely to require intensive care unit (ICU) care (51% vs 22%), P < 0.001. In multivariable logistic regression, children with neurological manifestations were older (odds ratio [OR] 1.1 and 95% confidence interval [CI] 1.07 to 1.13) and more likely to have MIS-C versus acute SARS-CoV-2 (OR 2.16, 95% CI 1.45 to 3.24), pre-existing neurological and metabolic conditions (OR 3.48, 95% CI 2.37 to 5.15; and OR 1.65, 95% CI 1.04 to 2.66, respectively), and pharyngeal (OR 1.74, 95% CI 1.16 to 2.64) or abdominal pain (OR 1.43, 95% CI 1.03 to 2.00); all P < 0.05. CONCLUSIONS: In this multicenter study, 44% of children hospitalized with SARS-CoV-2-related conditions experienced neurological manifestations, which were associated with ICU admission and pre-existing neurological condition. Posthospital assessment for, and support of, functional impairment and neuroprotective strategies are vitally needed.

Reliability of circulatory and neurologic examination by telemedicine in a pediatric intensive care unit.

OBJECTIVE: To test the hypothesis that telemedicine can reliably be used for many aspects of circulatory and neurologic examinations of children admitted to a pediatric intensive care unit (PICU). STUDY DESIGN: A prospective, randomized study in a 14-bed PICU in a tertiary care, academic-affiliated institution. Eligible patients were >2 months or <19 years of age, not involved in a concurrent study, had parents/guardian able to sign an informed consent form, were not at end-of-life, and had an attending who not only deemed them medically stable, but also felt that the study would not interrupt their care. Other than the Principal Investigator, 6 pediatric intensivists and 7 pediatric critical care fellows were eligible study providers. Two physician providers were randomly assigned to perform circulatory and neurologic examinations according to the American Heart Association/Pediatric Advanced Life Support guidelines in-person and via telemedicine. Findings were recorded on a standardized data collection form and compared. RESULTS: One hundred ten data collection forms were completed. For many aspects of the circulatory and neurologic examinations, outcomes showed substantial to perfect agreement between the in-person and telemedical care providers (kappa = 0.64-1.00). However, assessments of muscle tone had a kappa = 0.23, with a kappa = 0.37 for skin color. CONCLUSIONS: Telemedicine can reliably identify normal and abnormal findings of many aspects of circulatory and neurologic examinations in PICU patients. This finding opens the door to further studies on the use of telemedicine across other disciplines.
