ABSTRACT Objective:To systematically evaluate the risk factors for infections caused by carbapenem resistant Pseudomonas aeruginosa. Methods: Literature regarding the risk factors of CRPA infection were searched in PubMed, The Cochrane Library, Embase, CNKI, VIP and Wanfang database. The retrieval time was from inception to January 2018. Meta analysis was performed by RevMan 5.3 software. Subgroup analysis was carried out according to the population of different regions, and the sources of heterogeneity were found. Results: 22 studies (n=6 097) met the inclusion criteria. The results of Meta analysis, 8 risk factors of two groups were statistically significant: mechanical ventilation [OR=1.64, 95%CI(1.42, 1.89) ], use of carbapenems [OR=7.15, 95%CI(3.52, 14.52)], imipenem [OR=7.89, 95%CI(3.90, 15.93)], fluoroquinolone [OR=2.88, 95%CI(2.12, 3.90)], piperacillin tazobactam [OR=4.46, 95%CI(2.33,8.53)], vancomycin [OR=5.39, 95%CI(3.94, 7.37)], in ICU [OR=2.88, 95%CI(2.12, 3.90)], days of hospitalization [WMD=6.53, 95%CI(1.33, 11.73)](P<0.001). Subgroup analysis results of risk factors using carbapenems, imipenem, in which the Asian population was highly heterogeneous (P≤0.1, I2=87%), (P≤0.1, I2=85%). Conclusion: For high risk patients, it should be combined with risk factors and early take preventive measures to reduce the incidence of CRPA infection. |
