5年现患率调查与回顾性监测的对比研究

目的探讨现患率调查与回顾性监测两种方法的利弊及意义。方法将2001-2005年现患率调查与回顾性监测资料进行统计学处理。结果两种监测方法比较,感染率、感染部位例次率差异有统计学意义(P<0.01),提示回顾性监测存在着医院感染漏报病例;医院感染病原菌以革兰阴性杆菌为主,真菌呈逐年上升趋势;抗菌药物调查使用率均>50%。结论在回顾性监测的基础上采用现患率调查,能了解和掌握医院感染的动态变化,将两种监测方法的资料进行比较和综合分析,能较准确地反映医院感染状况,为医院制定目标性监测和预防与控制措施提供客观性、科学性依据。

Prevalence Rate and Retrospective Research of Nosocomial Infection in Five Years:A Comparative Study

OBJECTIVE To estimate the difference and meaning between prevalence surveying and retrospective research. METHODS These five year data measured by prevalence surveying and retrospective research from 2001 to 2005,were collected with statistics.RESULTS There had distinguished differences between the rate of nosocomial infection(NI) and the case of NI by comparing the data from two methods,it showed that some infected cases were failed to report by retrospective research in our hospital.G-was the main pathogen of NI now,but epiphytes had an ascend trend.The usage rate of antibiotics was more than 50%.CONCLUSIONS By prevalence survey we can know the changing trends of NI on the basis of retrospective research.The status of NI can be truly reflected by comparing and analyzing these data from two methods,which could offer objective and scientific evidence of target surveillance,prevention and control measures of NI.
