LOGISTIC REGRESSION ANALYSIS OF CLINICAL FEATURES AND RISK FACTORS FOR VENTILATOR-ASSOCIATED PNEUMONIA IN INTENSIVE CARE UNIT PATIENTS WITH ATHLETIC BACKGROUNDS

Abstract

This research was aimed to study the clinical features of ventilator-associated pneumonia (VAP) in the intensive care unit (ICU) and the risk factors under logistic regression analysis, so as to provide evidence for its protection. According to the occurrence of VAP after mechanical ventilation, 312 athletic patients were divided into VAP group and non-VAP group. The clinical manifestations, laboratory indicators, and other related data were counted, and the risk factors of VAP were analyzed by univariate and Logistic regression analysis. The results showed that VAP occurred in 85 cases (27.24%), of which 74 cases showed airway hypersecretion, and 73 cases with white blood cells (WBC) more than 10×10⁹/L. 96 strains of pathogenic bacteria were detected in 85 VAP cases, of which Gram-negative bacteria accounted for 76.04%. athletic Patients ≥ 60 years old, chronic obstructive pulmonary disease (COPD), severe pneumonia, Acute Physiology and Chronic Health Evaluation (APACHE-Ⅱ) score ≥ 15, coma, tracheotomy, ventilation time > 5 d, combined use of antibiotics, and gastric tube indwelling ratio in the VAP group were all significantly higher than those in the non-VAP group (P<0.05). Logistic analysis found that age ≥ 60 years old, APACHE-Ⅱ score ≥ 15, tracheotomy, ventilation time > 5 d, and combined use of antibiotics were independent risk factors for VAP (P<0.05). In conclusion, the pathogenic bacteria of VAP in ICU athletic patients were mainly gram-negative bacteria, and there were many risk factors for the occurrence of VAP. Targeted prevention and treatment were needed to reduce the incidence of VAP.
