ABSTRACT
Background: hospital-acquired pneumonia is a
constant challenge given the current microbiological
spectrum, antimicrobial resistance together with its
high mortality, morbidity and hospital costs.
Objective: to identify the clinical predictors of
pneumonia associated with acute ischemic stroke.
Methods: a prospective cohort study was conducted in 201 patients diagnosed with acute ischemic stroke
consecutively admitted to the stroke unit of the General
Carlos Manuel de Céspedes Teaching Hospital during
the first seven days after the onset, from January 2012
through December 2013. The independent predictors of
hospital-acquired pneumonia were obtained using
multivariable logistic regression.
Results: fifty six point seven percent were male. The mean age was 64.17 ± 14.33 years. Cases of
hospital-acquired pneumonia associated with stroke
accounted for 19, 9 %. Subjects who developed
pneumonia were older (68.55 ± 13.51 vs. 63.08 ±
14.36 years), had a lower score in the Glasgow Coma
Scale (8.00 ± 2.60 vs. 14.00 ± 2.82), and an increased number of leukocytes at admission (10.888 ± 3.487 vs. 9.233 ± 2.539 × 109/L). The following independent factors were identified: Glasgow Coma Scale ≤ 11 (OR: 26.099; 95 % CI 7.164-85.075), history of chronic obstructive pulmonary disease (OR: 8.896; 95 % CI 1.203 - 65.779), dysphagia (OR: 7.652; 95 % CI 2.369 - 24.720), history of heart failure (OR: 4.583; 95 % CI 1.240- 16.932) and dysarthria/severe motor aphasia (OR: 4.222; 95 % CI 1.374- 12.975).
Conclusions: the resulting logistic regression model is valid for predicting post-stroke pneumonia based on data routinely acquired.
