Background. The efficacy of antimicrobial therapy for Acinetobacter baumannii
bacteremia has been difficult to establish because of confounding by underlying
diseases, severity of infection and differences in the pathogenicity of Acinetobacter
species. This retrospective study was conducted to evaluate the effect of appropriate
antimicrobial therapy on 14-day mortality after adjustment for multiple risk factors.Methods. The population consisted of 252 patients with monomicrobial A. baumannii
bacteremia admitted to a large teaching hospital in Taiwan. The isolates were
identified to species level using reference molecular methods. Predictors of 14-day
mortality were determined by logistic regression analysis. The influence of severity of
infection, determined by Acute Physiology and Chronic Health Evaluation (APACHE)
II score, on the impact of appropriate use of antimicrobials on 14-day mortality was
assessed by including an interaction term.
Results. The overall 14-day mortality was 75/252 (29.8%). The unadjusted mortality
for appropriate antimicrobial therapy was 12/91 (13.2%). Appropriate therapy was
independently associated with reduced mortality (odds ratio , 0.22; 95%
confidence interval , 0.01-0.50; P < .001), and the effect was influenced by
APACHE II score (OR for interaction term, 0.90; 95% CI, 0.82-0.98; P = .02).
Subgroup analysis revealed that the benefit of appropriate therapy limited to patients
with high APACHE II scores (for scores > 25 and ≤ 35, OR, 0.16; 95% CI, 0.07-0.37
and for scores >35, OR, 0.06; 95% CI, 0.01-0.25).
Conclusions. Appropriate antimicrobial therapy significantly reduced 14-day
mortality for A. baumannii bacteremia in severely ill patients.
是说鲍曼不动杆菌吗？和抗生素使用之间的关系？英文水平实在不行，大概只能看出这个意思。{:1_10:} 值得关注的是医院的电子信息系统非常完备。对于本文回顾性研究的成果有着重要的铺垫作用。

谢谢老师，看来要加强学习了，看的我一头汗，惭愧！
