目的:探讨循证医学对控制院内多重耐药菌肺部感染的作用。方法:将170例在2010年住院的脑卒中后患者,随机分为循证组(86例)和对照组(84例),循证组采用预防肺部感染的循证防控措施,对照组实施传统治疗。运用回顾性调查和前瞻性监测方法观察院内肺部感染率及肺部多重耐药菌感染率的变化。结果:实施循证医学多重耐药菌肺部感染率显著下降,与上一年及同期对照组相比,经χ2检验,P<0.05,结果有统计学意义。结论:循证医学能有效预防脑卒中后多重耐药菌院内肺部感染,提高患者的生存质量,降低死亡率和医疗费用。
Objective: To investigate the role of evidence-based medicine in the control of multiple drug-resistant bacterial lung infections in hospital. Methods: A total of 170 post-stroke patients hospitalized in 2010 were randomly divided into evidence-based group (86 cases) and control group (84 cases). Evidence-based prevention and control measures were used in evidence-based group to prevent lung infection. Implement traditional treatment. Retrospective investigation and prospective monitoring methods were used to observe the changes of nosocomial lung infection rate and lung multi-drug resistant bacteria infection rate. Results: Compared with the control group in the previous year and the same period of the previous year, the lung infection rate of multidrug-resistant bacteria in evidence-based medicine was significantly lower than that in the control group (P <0.05) by χ2 test. The results were statistically significant. CONCLUSION: Evidence-based medicine can effectively prevent lung infections in hospitals with multiple drug-resistant bacteria after stroke, improve patients’ quality of life, reduce mortality and medical expenses.
