    Abstract
  •   Objective  To explore the detection and distribution of multi-drug resistant organism (MDRO) in the Hospital of China Seventeenth Metallurgical Group Co., Ltd.  Methods  The monitoring data for MDROs isolated from clinical thesamples submitted by the hospital of China Seventeenth Metallurgical Group Co., Ltd. from 2016 to 2018 were analyzed retrospectively.  Results  From 2016 to 2018, 314 strains, 420 strains and 359 strains of MDROs were detected. The isolation rate of MDROs were 28.31%, 35.35% and 30.95%, with statistically significant difference (P < 0.05). MDROs accounted for more than 30.00% of the isolated pathogens in both 2017 and 2018. The positive rates of klebsiella pneumoniae producing ESBLs were 33.90%, 67.54% and 40.98% in 2016, 2017 and 2018, respectively (P < 0.05). The detection rates of Methicillin-resistant Staphylococcus aureus (MRSA) were 20.51%, 19.09% and 38.53% in 2016, 2017 and 2018 respectively (P < 0.05). The detection rates of Acinetobacter baumannii with multiple-drug resistance were 68.42%, 46.15% and 45.24% in 2016, 2017 and 2018, respectively (P < 0.05), showed a decreasing trend year by year. The detection rates of carbapenems-resistant Klebsiella pneumoniae were 0.00%, 5.26% and 9.84% in 2016, 2017 and 2018, respectively (P < 0.05), showing an increasing trend year by year. The department with the highest proportion of MDROs detection was internal medicine, followed by ICU. The composition ratio of MDROs in urology were 9.24%, 9.76% and 6.41%, respectively (P < 0.05). The composition ratio in brain surgery were 1.59%, 1.46% and 5.57%, respectively (P < 0.05). The most common types of specimens with high detection rates of MDROs were sputum, urine, and others.  Conclusion  The detection rate of MDROs showed an overall increase, especially the isolation rate of carbapenems-resistant Klebsiella pneumoniae was increasing year by year. The prevention, control and management of MDROs infection should be strengthened to promote the rational use of antibiotics in clinical practice.
