Abstract: Objective To investigate the patient screening for multidrug-resistant organisms (MDROs) on admission to the 10 community hospitals in Beijing. Methods The patients admitted to the 10 community hospitals in Xicheng district were enrolled in the study from June 11, 2015 to September 30, 2016. The patients were divided into hospital group and community group according to the place before admission. Nasal swabs and anal swabs were collected within 48 hours after admission. Chromogenic culture medium technology was used to identify methicillin resistant staphylococcus aureus (MRSA), extended-spectrum β-lactamases (ESBL)-producing Enterobacteriaceae, and vancomycin resistant enterococcus (VRE). The positive percentage and distribution of the MDROs were compared between the groups. We also try to find risk factors for the positive MDROs. Results A total of 644 patients were enrolled in the study, among which 220 of the 304 patients in the hospital group showed positive screening at least one site, significantly higher than that of the 340 patients in community group (72.4% vs 51.5%, P<0.001). The positive percentage of nasal swab in hospital group was higher than that in the community group (11.8% vs 3.2%, P<0.001). The MRSA was the most found MDROs. The positive percentage of anal swab was higher than that of nasal swab in both groups. The patients with positive anal swab screening for 2 or more MDROs were significantly higher in the hospital group than that in the community group (18.9% vs 12.8%, P=0.046), especially with Escherichia coli (ECO) and Klebsiella-Enterobacter-Serratia-Citrobacter (KESC). Cerebrovascular disease, hypertension,surgery or interventional procedure, antibiotic exposure within 4 weeks prior to admission, and systemic inflammatory response syndrome (SIRS) on admission were risk factors for positive MDROs screening. Conclusion The positive MDROs screening were found in more than half of the patients admitted to the 10 community hospitals, especially, in patients transferred from tertiary hospital nearby. We should pay sufficient attention to these patients.
