ObjectiveTo explore risk factors for catheterassociated urinary tract infection (CAUTI) in hospitalized patients, and provide reference for prevention of CAUTI.MethodsCase control studies about the risk factors for CAUTI in hospitalized patients were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, China Biology Medicine (CBM), and PubMed from 2007 to 2017. After literature screen, data extraction, and quality evaluation were performed, Revman 5.3 software was used to carry out comprehensive quantitative analysis, OR value and 95% confidence interval (CI) for each risk factor was calculated.ResultsA total of 10 literatures were included, with a total of 2 652 patients. Seven risk factors that with predictive value for CAUTI were extracted from literatures, Meta analysis results showed that the combined OR value of each factor and its 95%CI were as follows: urinary catheter indwelling time (OR, 1.57 ［95%CI, 1.33-1.86］), age≥60 years (OR, 2.24 ［95%CI, 1.09-4.59］), gender (OR, 1.21 ［95%CI, 0.54-2.72］), diabetes mellitus (OR, 3.49 ［95%CI, 2.61-4.66］), antimicrobial use (OR, 2.58 ［95%CI, 0.70-9.55］), disturbance of consciousness (OR, 4.51 ［95%CI, 3.33-6.09］), and No. of intubation≥2 times (OR, 2.60 ［95%CI,1.62-4.18］). Two risk factors (gender and antimicrobial use) were not statistically significant(P>0.05), combined results of other factors were statistically significant (all P<0.05).ConclusionUrinary indwelling time≥5 days, patients’ age≥60 years, combined with diabetes mellitus, disturbance of consciousness, and No. of intubation≥2 times are  main risk factors for CAUTI; predictive value of gender and antimicrobial use in CAUTI needs to be further evaluated. Nursing staff should pay more attention to the above factors and take specific preventive measures to reduce the incidence of CAUTI.
