Objective To explore the risk factors and its related prognostic factors of the pneumonia caused by Carbapenemresistant gramnegative bacteria(CRGNB).Methods We retrospectively analyzed the clinical materials of patients diagnosed by gramnegative bacteria pneumonia in 2016. According to the sputum or bronchoalveolar lavage fluid(BALF) culture results, patients were divided into CRGNB group (n=114) and nCRGNB group (n=112). We further divided CRGNB group into survived (n=88) and died (n=26) in terms of patients' 30 day prognosis.We conducted the statistical analysis using univariate analysis and multivariate analysis to identify independent risk factors for CRGNB and associated mortability in pneumonia patients. Results Univariate analysis revealed that eleven factors were associated with the pneumoniae caused by CRGNB, including ICU stay, recent history of surgery, bedridden, fever, conscious disturbance, carbapenem antibiotics application in past 90 days, respiratory failure, shock, invasive manipulation, ABA and SMA infection, hospital acquired. ICU stay, coronary heart disease, diabetes mellitus, renal failure, respiratory failure, shock, retention catheterization, deep vein catheterization and mechanical ventilation were associated with the mortality of CRGNB pneumonia. Multivariate analysis showed that Carbapenem antibiotics application in past 90 days, mechanical ventilation, ABA infection and hospital acquired is independent risk factor of CRGNB. Furthermore, shock, deep vein catheterization, diabetes mellitus and coronary heart diseases were independently associated with mortality of CRGNB pneumonia. Conclusion Carbapenem antibiotics application in past 90 days, mechanical ventilation, ABA infection and hospital acquired is independent risk factor of CRGNB. Furthermore, shock, deep vein catheterization, diabetes mellitus and coronary heart diseases were independently associated with mortality of CRGNB pneumonia.
