Abstract Objective To investigate the related risk factors of inpatients with hospital acquired infection (HAI) in the department of gastroenterology. Methods Five hundred and sixty-five inpatients from August 2014 to January 2016 were selected as the research objects. Relative risk factors of HAI in patients were analyzed with single factor chi-square test and the binary classification unconditional logistic regression equation. Results Eighty-five inpatients in the department of gastroenterology were with HAI and the infection rate was 15.0%. The most common part of infection was the lower respiratory tract (31.7%), followed by the upper respiratory tract (26.8%), and the urinary tract (18.3%). Multivariate Logistic regression analysis showed that age (OR=1.382,95%CI:1.167~4.154), diabetes mellitus (OR=1.454,95%CI:1.150~3.341), the digestive tract tumor (OR=1.382,95%CI:1.167~4.154), the combined use of antibiotics (OR=1.693,95%CI:1.253~4.541), serum albumin levels <40 (g/L) (OR=1.522,95%CI:1.311~2.651), the hs CRP acuity 10 mg/L (OR=1.304,95%CI:1.126~1.984), and invasive operation (OR=1.593,95%CI:1.242~5.761) were independent risk factors of HIA. Conclusion Inpatients in the department of gastroenterology have risks of hospital-acquired infection, and the risk factors were such as age, diabetes, antibiotics application way, the digestive tract tumor, serum albumin, hs-CRP level and the impact of invasive operation.
