OBJECTIVE：To provide reference for clinical empirical treatme nt of non-fermentative Gram-negative bacilli （NFGNB）infection. METHODS ：All kinds of clinical specimens were collected from Jan. 2010 to Dec. 2019 in a tertiary hospital from Hanzhong city of Shaanxi province ；the distribution and drug resistance of NFGNB were analyzed retrospectively. RESULTS ： A total of 26 386 strains of pathogenic bacteria were detected in the hospital during 2010-2019，including 4 077 strains of NFGNB （15.45％），mainly from patients ≥60 years old （1 836 strains，45.05％）. During the 10 years，the detection rate of NFGNB decreased from 20.14％ in 2010 to 15.36％ in 2019 （P＜0.001）. Acinetobacter baumannii （1 359 strains），Pseudomonas aeruginosa （1 269 strains），Stenotrophomonas maltophilia （447 strains） and Burkholderia cepacia （351 strains） were main pathogens. The detected NFGNB mainly came from hospitalized patients （4 001 strains），and most of them were found in ICU （17.05％），neurosurgery department （14.52％），respiratory department （12.41％），and respiratory tract （66.69％），secretion （7.80％）specimens. The detection rates of A. baumannii and P. aeruginosa in oncology department ，blood specimens and urine specimens showed an overall upward trend ，while the detection rates in ICU of the hospital showed a downward trend （P＜0.05）； the detection rate of P. aeruginosa in neurosurgery department showed an upward trend （P＜0.05），and that of A. baumannii in respiratory department showed an upward trend （P＜0.05）. The resistance rate of A. baumannii to carbapenems increased from about 10％ in 2010 to about 75％ in 2019，and the guyh3201@163.com resistance rate to cephalosporins exceeded 78％. The resistance rates of P. aeruginosa to imipenem and me ropenem were lower than 35％ and 30％ respectively，and the trend of drug resistance did not change significantly （P＞0.05）；the resistance rates to 12 kinds of clinically commonly used antibiotics as piperacillin and aztreonam were lower than 40％. The resistance rate of S. maltophilia to compound sulfamethoxazole showed a decreasing trend （P＜0.001），and the resistance rate to ceftazidime was high （54.70％-74.10％）. The resistance rates of B. cepacia to compound sulfamethoxazole，meropenem and ceftazidime showed a downward trend （P＜0.01），and were lower than 15％ after 2014. CONCLUSIONS：Although the detection rate of NFGNB in our hospital showed a downward trend ，the multi-drug resistance and pan-drug resistance of A. baumannii are serious ，and the resistance rate to carbapenems is increased. Sensitive drugs such as cefoperazone/sulbactam，amikacin，levofloxacin and ceftazidime should be selected for NFGNB infection according to the results of drug sensitivity tests.
