Objective To understand the clinical distribution characteristics of Acinetobacter baumannii in our hospital and the change situation of drug resistance rates to provide a basis for the clinical rational drug use and the nosocomial infection manage-ment.Methods The Acinetobacter baumannii strains isolated in our hospital from January 2005 to December 2013 were performed the retrospective analysis on its department distribution,specimen distribution and change of drug resistance rates.Results 964 strains of Acinetobacter baumannii were isolated during these 9 years,in which 713 strains were multi-drug resistant.The isolated strains were less during 2005 -2008,which were 30,26,22,19 strains respectively.The isolated strains began to increase during 2009-2010,which were 65,50 strains respectively.The detection rate began to enormously increase from 2011,which were 157, 229,366 strains respectively from 2011 to 2013.The top three departments of the highest isolation rates during these 9 years were ICU,neurosurgery department and respiratory department.The specimen source was always dominated by the respiratory tract specimens,followed by the secretion samples,in recent years,the detection rates of blood,urine and drainage specimens were in-creased to some extent.The drug resistance rates in 13 kinds of drugs totally showed the increasing trend,the resistance rate of par-tial drugs was decreased to some extent.Conclusion Acinetobacter baumannii easily cause nosocomial infections,which is difficult to be eliminated and has high occurrence in the departments centralized with critical patients.The respiratory infection is the main pathogenic type.Its drug resistance is serious,multi-drug resistant and pan-resistant strains have the higher proportion.Clinic should rationally use the drugs based on the drug susceptibility test results,coordinates with the infection control departments for doing disinfection and isolation well and prevent ing the outbreak of nosocomial infections.

Objective To learn the species distribution characteristics and proportion occurrence of methicillin-resistant strains about Staphylococcus detected in the First People′s Hospital of Kunming.Methods The species distribution characteristics and proportion occurrence of methicillin-resistant strains were analyzed retrospectively from January 2005 to December 2013.Results A total of 3 561 Staphylococcus strains were detected in 9 years,included 21 species and subspecies,and another 12 strains were not i-dentified to species.2005-2013 species composition showed an increasing trend,there were five kinds of Staphylococcus in 2005, until 2013 reach to 13 kinds.Each year the main bacterial were Staphylococcus aureus,Staphylococcus epidermidis,Staphylococcus haemolyticus and staphylococcal hominis.Methicillin resistant Staphylococcus aureus incidence decreased significantly since 201 1, decrease from 76.3% in 2010 to 25.6% in 2013.Staphylococcus epidermidis,Staphylococcus haemolyticus,Staphylococcal hominis and coagulase-negative Staphylococci resistant to high incidence of methicillin-resistant strains of the average,remained stable at a-round 70.0%.Conclusion The distribution characteristic of Staphylococcus in this hospital was increasingly complex year by year, the opportunity of infection caused by Staphylococcus was also increased,the detection rate of methicillin-resistant strains was high, it should be noted to use clinical drug rationally.

Objective To investigate the status quo of oral nursing in the emergency department of top three hospitals in Shanxi province, and to analyze the existing problems so as to provide the basis and reference for improving the clinical operation standard. Methods In the form of WeChat questionnaire, a questionnaire survey was conducted to investigate 190 nurses who met the requirements in emergency departments of 6 top three hospitals in Shanxi province. Results All the 6 hospitals surveyed did not incorporate oral care into the nurse examination program; 28.42％(73/190) of the subjects had oral assessments of endotracheal intubation according to their clinical experience;chlorhexidine (70.00％,133/190) and physiological saline (65.79％,125/190) were the most commonly used oral care solutions in clinic;48.42％(92/190) of nurses performed this operation for 6-10 min;91.58％(114/190) of nurses believed that oral care played an important role in the recovery of these patients. Conclusions The oral care and oral care of the patients in the emergency department are mostly clinical experience, so it is urgent to establish a unified standard of implementation on the basis of evidence. The professional knowledge of oral nursing of the patients undergoing oral trachea intubation is low, so it is suggested that the training of emergency nurses be strengthened and the operation should be included in the assessment of nursing operations.

Objective:To explore the effect of the Six Sigma management in reducing the pre-examination and triage error rate of emergency acute abdominal diseases.Methods:Data of 367 misdiagnosed patients in Emergency Department of Shanxi Bethune Hospital from January to June 2018 were collected. Six Sigma management method was applied to the management of emergency acute abdomen triage. After analyzing the causes of errors, improvement measures were formulated and implemented.A total of 118 patients who were triaged from September 2018 to February 2019 were taken as the intervention group to evaluate the effect.Results:After the implementation of Six Sigma management, the errors of acute abdomen diagnosis were significantly reduced from 9.92%(367/3 698) to 2.80%(118/4 219), and there was a significant difference before and after the implementation ( χ2 value was 174.082, P < 0.05). Conclusions:The application of Six Sigma management method can effectively reduce the misdiagnosis rate of emergency acute abdomen triage and realize standardized management of acute abdomen triage, which has the value of popularization and application.

Objective To provide some evidence for early empirical treatment of infections caused by Pseudanonas aeruginosa(PA)and establish a certain foundation for further studies on its resistance mechanisms.Analyzed the resistance rate of PA and the phenotype characteristics for seven years at this hospital.Methods Using Whonet 5.6 software,the drug sensitivity data of PA isolated and reported from clinical specimens at Kunming First People's Hospital from 2016 to 2022 were analyzed annually.Imipenem,meropenem,ceftazidime,and cefepime were the main observation objects,statisticaly analyze the resistance of other antibiotics under different drug resistance combinations of the above-mentioned drugs Results A total of 1 920 strains of PA were detected in 7 years,with polymyxins exhibiting the lowest resistance rate at 1%.The average resistance rates for Amikacin,Gentamicin and Tobramycin were 6.4%,8.6%and 5.1%,respectively.The resistance rates of Quinolones,Piperacillin/Tazobactam,Ceftazidime,and Cefepime were similar,ranging from 10%～20%.Imipenem and Meropenem did not show better sensitivity,with resistance rates of 21.3%and 18.4%,respectively.The resistance rates of major antibiotics have fluctuated over the past 7 years,mostly increasing from 2017 to reaching a peak in 2018 and then falling back.And then stabilized with the domestic average level.1 393 strains were sensitive to Imipenem,and the sensitivity rate of Meropenem in this part was 96.2%.1 451 strains were sensitive to Imipenem,and 89%of them were sensitive to Meropenem at the same time.369 strains were both resistant to Imipenem and Meropenem,and 33.1%of them were sensitive to Ceftazidime.The more resistant to β-lactam,the lower the sensitivity rate to Amikacin and Ciprofloxacin.Conclusion The overall drug sensitivity of PA in this hospital is relatively good.Should adhere to strict management of antibiotic use.Aminoglycosides can be the preferred drugs for empirical treatment,followed by Quinolones,and Carbapenems and Ceftazidime are also candidates.PA has diverse resistance mechanisms to β-lactam antimicrobials,and carbapenem-resistant strains can be mediated by different mechanisms or jointly.
