AbstractTo investigate the risk factors of nosocomial pneumonia (NP) in elderly patients with acute cerebral infarction (ACI).In this study, 324 aged 70 years and over patients with ACI who were admitted to the inpatient department of TianJin First Hospital (China) from January 2012 to February 2018 were retrospectively analyzed. The patients were divided into NP group (80 patients) and non-NP group (244 patients) according to whether NP was occurred 48 hours after hospitalization. Baseline profiles and biochemical analyses were compared between 2 groups. Information regarding risk factors for NP in elderly patients with ACI was collected from all patients. Associations with NP and outcome were evaluated.Among the total patients, NP occurred in 80 (24.69%) patients. There were no statistically significant differences between risk of NP and sex, current drinking, diabetes mellitus, stroke history, and levels of serum UA, TG, HDL-C, LDL-C, Glucose, chloride, potassium. Multivariate logistic regression analysis showed that the independent risk factors for NP were living alone (OR 4.723; CI 1.743∼12.802; P = .002), initial NIHSS score (OR 1.441; CI 1.191∼1.743; P = .000), NRS2002 score (OR 0.139; CI 0.087∼0.223; P = .000), BMI (OR 1.586; CI 1.353∼1.858; P = .000), a past pneumonia history (OR 0.073; CI 0.017∼0.321; P = .001), atrial fibrillation (AF) (OR 0.129; CI 0.033∼0.499; P = .003), CRP (OR 1.050; CI 1.017∼1.085; P = .003), BUN (OR 0.603; CI 0.448∼0.812; P = .001) and Cr (OR 1.036; CI 1.015∼1.057; P = .001). Level of albumin was an independent protective factor of NP in elderly patients with ACI (OR 0.865; CI 0.750∼0.999; P = .048). Furthermore, elderly patients with ACI who had NP had worse clinical outcomes both during hospitalization and after discharge (P < .05).We identified significant risk factors for NP in elderly patients with ACI, including living alone, initial NIHSS score, malnutrition, a past pneumonia history, AF, CRP, and Renal function were associated with NP in elderly patients with ACI. The clinical course was worse and the duration of hospital stay was longer in NP patients than in non-NP patients.
