OBJECTIVE: The incidence of SAP (stroke-associated pneumonia) is high in integrated ICU (Intensive Care Unit), and it might result in sepsis, which exacerbates the clinical outcome and increases mortality. It is necessary to investigate the epidemiological features of post-stroke infection and sepsis, identify the risk factors and analyze the prognosis.

PATIENTS AND METHODS: We retrospectively analyzed the data of 329 patients with cerebral infarction or cerebral hemorrhage, from seven tertiary university hospitals in Suzhou, Jiangsu Province, between January 1, 2016, and December 31, 2016. Basic demographic and clinical data including common health evaluation, stroke severity, microbiological parameters, surgical interventions and treatments were recorded for the analysis. SAP was diagnosed according to the criteria and recommendation from American Heart Association (AHA).

RESULTS: 188 (66.4%) patients suffered pneumonia, 124 patients were diagnosed as SAP. Compared with SAP, patients with non-SAP pulmonary infection had prolonged mechanical ventilation time, prolonged central venous catheter indwelling time, and higher incidence of sepsis (17.7% vs. 48.4%). 53 patients (18.7%) developed sepsis during hospitalization, whose mortality rate during hospitalization and the occurrence of neurologic dysfunction at 3 months were significantly increased (p<0.05). 130 positive results of sputum cultures were found. The detected pathogens were mainly gram-negative bacteria. The pathogenic detection rate of non-SAP patients with pulmonary infection was higher (78.1%). The in-hospital mortality was 16.3% and the related risk factors were higher NIHSS score at admission, lower GCS score at admission, pulmonary infection (especially non-SAP pulmonary infection) and sepsis during hospitalization.

CONCLUSIONS: The incidence of pulmonary infection after stroke in the integrated ICU is high, and it is easy to be complicated with sepsis, prolonging the mechanical ventilation time, central venous catheter indwelling time and hospitalization time, and the prognosis of long-term neurological function is relatively poor. The definition of stroke-associated pneumonia has implications for the classification of clinical infections, the prediction of possible pathogenic pathogens, and the guidance of anti-infective treatment.
