Study on the related risk factors and targeted nursing effects in multi-drug resistant bacteria infections in elderly patients with stroke-associated pneumonia

PURPOSEto explore the related risk factors and targeted nursing effects in multi-drug resistant bacteria (MDRB) infection in elderly patients with stroke-associated pneumonia. METHODSWe selected 100 elderly patients with MDRB who received SAP in the hospital encephalology department from May 2011 to November 2014, and pathogenic detection and drug susceptibility tests were performed on the specimens sent for inspection. In addition, we observed the pathogenic characteristics of MDRB, and carried out univariate and multivariate regression analysis of related risk factors. The infected patients were randomly divided into a control group and an intervention group, each with 50 cases. The control group received routine nursing care, and the intervention group received targeted nursing interventions, and the nursing effect of the two groups of patients was compared and analyzed. RESULTSA total of 112 drug-resistant bacteria were isolated from 100 SAP patients; gram-positive bacteria accounted for 22.3%, gram-negative bacteria accounted for 74.1%, fungi accounted for 3.6%. The multi-factor analysis showed that SAP type, ICU admission, gastric catheter retention, length of hospital stay, prophylactic use of antibiotics and disturbance of consciousness are risk factors associated with MDRB. The total effective rate of the control group was 50.0%, and the total effective rate of the intervention group was 74.0%, the difference between the two groups was statistically significant (P
