RESUMO
BACKGROUND: Neurological disorders are significant causes of morbidity and mortality worldwide. However, data about general neurological inpatient admissions in Brazil is limited. Objective: To investigate the prevalence of neurological disorders according to disease group and lesion site among patients admitted to a general Neurology ward. METHODS: This was an observational and descriptive study. The hospital discharge database for the Neurology ward was surveyed in accordance with the International Classification of Diseases, 10th edition (ICD-10), from September 2008 to October 2019. The final diagnosis was classified into neurological disorder groups and site. RESULTS: Overall, 2,606 clinical neurological patient files were included, with mean length of hospitalization of 16.7 days and a total of 325 readmissions (12.5%). The overall mortality rate in the ward was 3.8% (100 patients). Among all the diagnoses, cerebrovascular disease was the most prevalent (45.8%), followed by inflammatory disorders (22.2%). The brain was the most common lesion site (66.0%), followed by peripheral nerves (10.0%) and meninges and cerebrospinal fluid (7.7%). CONCLUSIONS: The disease pattern upon admission showed that a majority of the cases consisted of cerebrovascular disorders and that the brain was the most frequently affected structure, although we observed that a wide variety of cases were admitted, encompassing all neurological disorders.

RESUMO Introdução: As doenças neurológicas representam importante causa de morbidade e mortalidade globalmente, mas informações acerca de internações hospitalares em neurologia no Brasil são limitadas. Objetivo: Investigar a prevalência de admissões neurológicas por grupo de doenças e pela topografia atendidas em uma enfermaria de neurologia geral. Métodos: Estudo observacional e descritivo. Avaliados diagnósticos de saída de acordo com o Código Internacional de Doenças-10 (CID-10) no período de setembro de 2008 a outubro de 2019. Os diagnósticos foram classificados em grupos de doença e por topografia. Resultados: Foram incluídos 2,606 pacientes, com tempo médio de internação de 16,7 dias e um total de 325 (12,5%) readmissões. A mortalidade geral na enfermaria foi de 100 (3,8%) pacientes. A doença cerebrovascular foi mais prevalente (45,8%), seguida das doenças inflamatórias (22,2%). A topografia encefálica foi a mais comum (66,0%), seguida de nervos periféricos (10,0%), meninges e líquido cefalorraquidiano (7,7%). Conclusões: O perfil de doenças observado neste estudo demonstrou maior prevalência das doenças cerebrovasculares e da topografia encefálica, embora uma grande variedade de doenças tenha sido admitida dentro do espectro de doenças neurológicas.
