Early identification of risk factors for CRKP infections is important, but these factors are still controversial. Therefore, we aimed to identify the risk factors and clinical outcomes of CRKP infections.Patients and Methods: The retrospective, single-center study was carried out in the respiratory intensive care unit of the Chinese People’s Liberation Army General Hospital from 2017 to 2020. Patients infected with K. pneumoniae were included and categorized into the CRKP group and carbapenem-sensitive K. pneumoniae (CSKP) group based on the susceptibility to carbapenems. The independent risk factors were investigated by univariate analysis and multivariate logistic regression analysis. The clinical outcomes were also evaluated between the two groups.Results: A total of 138 eligible patients were included in our study, with a median age of 80.5 years (interquartile range: 62.0– 86.3), and 78.3% of them were males. Of the 138 patients, there were 97 patients in the CRKP group, and the other 41 were assigned into the CSKP group. Multivariate analysis showed that exposure to ≥three types of comorbidities (OR = 5.465, P = 0.003), previous hospitalization (OR = 4.279, P = 0.006), use of quinolones (OR = 5.872, P = 0.012), and indwelling urinary catheter (OR = 5.035, P = 0.000) were independent risk factors for CRKP infections. The in-hospital mortality rate of the CRKP group was 42.1%, which was higher compared with the CSKP group (17.5%, P = 0.006).Conclusion: Exposure to ≥three types of comorbidities, previous hospitalization, use of quinolones, and indwelling urinary catheter were independent risk factors for CRKP infections, which had higher mortality compared with CSKP infections. Early detection of high-risk patients and timely control measures should be implemented to prevent the emergence of CRKP infections and thereby improve the clinical outcomes.Keywords: carbapenems, Klebsiella pneumoniae, resistance, risk factors, prognosis |
