Clinical features and outcomes of inpatients with neurological disease and COVID-19
Abstract
Objective
To report the clinical and laboratory characteristics, as well as treatment and clinical outcomes of patients admitted for neurological diseases with COVID-19 in a Neuro-COVID unit compared to patients without COVID-19.
Methods
In this retrospective, single centre cohort study, we included all adult inpatients with confirmed COVID-19, who had been discharged or died by April 5, 2020. Demographic, clinical, treatment, and laboratory data were extracted from medical records.
Results
173 patients were included in this study, of whom 56 resulted positive for COVID-19 and 117 resulted negative for COVID-19. Patients with COVID-19 were older, had a different distribution regarding admission diagnoses, including cerebrovascular disorders, and had a higher quick Sequential Organ Failure Assessment (qSOFA) score on admission (all p<0.05).
In-hospital mortality rates and incident delirium were significantly higher in the COVID-19 group (all p<0.05). COVID-19 and non-COVID patients with stroke had similar baseline characteristics but patients with COVID-19 had higher modified Rankin scale scores at discharge (p<0.0001), with a significantly lower number of patients with a good outcome (p<0.0001).
Multivariable regressions showed increasing odds of in-hospital death associated with higher qSOFA scores (odds ratio 4.47, 95% CI 1.21-16.5; p=0.025), lower platelet count (0.98, 0.97-0.99; p=0.005) and higher lactate dehydrogenase (1.01, 1.00-1.03; p=0.009) on admission.
Conclusions
COVID-19 patients admitted with neurological disease, including stroke, have a significantly higher in-hospital mortality, incident delirium and higher disability than patients without COVID-19.
