Abstract
Purpose: to assess the demographic and clinical characteristics associated with the development of pneumonia in post-stroke patients hospitalized in a tertiary hospital, located in the Vale do São Francisco, that covers the states of Pernambuco and Bahia, Brazil.
Methods: a unicentric, observational, analytical, cross-sectional study, based on the medical records of patients diagnosed with stroke and included in the Stroke Registry (RAVESS study). The statistical analysis was made with the chi-square test, Fisher’s exact test, and the analysis of variance, with the Bonferroni’s post-test, and P≤0.05.
Results: data from 69 patients presented with acute stroke were collected, aged 63.2±16.8 years; 37 (53.6%) were females; the prevalence of pneumonia during hospital stay was estimated at 31.9% (95% confidence interval: 21.2–44.2%). In the univariate analysis of predictors for post-stroke pneumonia, the following were identified: older age (72.6±17.9 vs. 58.8±14.5; P = 0.001), lower response signal to the Glasgow Coma Scale at admission (11.3±1.8 vs. 13.3±2.1; P = 0.001), and higher frequency of dysarthria at admission (61.9% vs. 27.9%; P = 0.009).
Conclusion: pneumonia was a prevalent complication in post-stroke patients at a Brazilian tertiary hospital. It was related to the patient’s older age and the severity of the cerebral event.

Resumo
Objetivo: avaliar as características demográficas e clínicas associadas ao desenvolvimento de pneumonia em pacientes após acidente vascular encefálico internados em um hospital terciário do Vale do São Francisco que atende os estados de Pernambuco e Bahia, Brasil.
Métodos: trata-se de estudo unicêntrico, observacional, analítico e transversal realizado a partir dos prontuários de pacientes com diagnóstico de acidente vascular encefálico incluídos no Registro de Acidente Vascular Encefálico (Estudo RAVESS). A análise estatística foi composta pelos testes qui-quadrado, exato de Fisher e a análise de variância com pós-teste de Bonferroni com nível de P≤0,05.
Resultados: foram coletados dados de 69 pacientes com AVE agudo com média±desvio padrão de idade de 63,2±16,8 anos, sendo 37 (53,6%) do sexo feminino, com prevalência de pneumonia durante o internamento estimada em 31,9% (Intervalo de Confiança de 95%: 21,2–44,2%). Na análise univariada para preditores de pneumonia após acidente vascular encefálico foram identificados: idade mais avançada (72,6±17,9 vs. 58,8±14,5; P=0,001), menor sinal de resposta a escala de coma de Glasgow durante a admissão (11,3±1,8 vs. 13,3±2,1; P=0,001) e maior frequência de disartria na admissão (61,9% vs. 27,9%; P=0,009).
Conclusão: a pneumonia foi uma complicação prevalente em pacientes após acidente vascular encefálico de um hospital terciário brasileiro, tendo sido relacionada com idade avançada do paciente e a severidade do evento encefálico.
