Abstract: Objective: To analyze the pathogens of multidrug-resistant organism (MDRO) in the comprehensive internal medicine
department of Dali Bai Autonomous Prefecture People s Hospital ( hereinafter referred to as “our hospital” ), and to explore the risk
factors and propose effective nursing strategies. Methods: From January 2010 to June 2017, 82 patients with MDRO lung infection were
treated in our hospitals comprehensive internal medicine department. The types of pathogens and their therapeutic effects were analyzed.
Meanwhile, effective nursing strategies were put forward. Results: In our hospital, the majority of MDRO were Pseudomonas
aeruginosa (37.80%), Klebsiella pneumoniae (26.83%), Acinetobacter baumannii (20.73%), and Staphylococcus aureus (10.98%).
Major risk factors of MDRO lung infection were irrational use of antibiotics, indwelling gastric tube, mechanical ventilation, long
hospital stay, smoking history and other underlying diseases. After targeted care, more than 79.27% of the patients with MDRO lung
infection were improved and discharged. Conclusion: Finding out risk factors, identifying pathogens, and giving effective nursing
intervention are the keys to reducing the occurrence of MDRO lung infection.
