Pneumonia risk factors in stroke patients

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.
