Abstract:
Objective To investigate the risk factors of multi-drug resistant organism(MDRO) infection in the patients with stroke associated pneumonia in ICU (ICU-SAP) and to analyze the composition of pathogenic bacteria.Methods The medical record data of 158 inpatients with ICU-SAP in our hospital from January 2013 to June 2016 were collected and screened the influence factors for MDRO infection occurrence in ICU-SAP.Results One hundred fity-eight cases of ICU-SAP,106 cases developed MDRO infection,and the infection rate was 67.1％.A total of 146 strains of MDRO were isolated,of which 31 strains (21.2％) were Gram-positive bacteria and 115 strains(78.8 ％) were Gram-negative bacteria.The Logistic regression analysis showed that the risk factors for MDRO infection in ICU-SAP patients included late-onset SAP,ICU stay time(≥72 h),disturbance of consciousness,swallowing disorders and APACHE Ⅱ (＞25 points).Conclusion The proportion of ICU-SAP patients infected with MDRO is high,and Gram-negative bacilli are the primary pathogen.These factors such as late-onset SAP,long ICU stay time,disturbance of consciousness,swallowing disorders and increased disease severity increase the MDRO infection risk,which should be paid attention to in order to reduce the morbidity of MDRO infection.
