医院感染目标性监测与全面综合性监测方法的对比研究

目的调查医院感染目标性监测与前瞻性全面综合性监测方法对神经外科术后医院感染发病率,分析两种方法的优劣及意义。方法采用目标性监测方法对2003年5~12月,神经外科住院手术患者的医院感染发生情况进行监测,与2002年5~12月间神经外科前瞻性全面综合性监测的医院感染发生情况进行统计学分析。结果目标性监测267例神经外科手术患者术后共发生100例,136例次医院感染,医院感染发生率为37.5%,感染例次发病率为50.9%,明显高于2002年5~12月间,前瞻性全面综合性监测248例神经外科手术患者术后医院感染发生率20.2%和感染例次发病率21.4%,统计学处理差异有统计学意义(P<0.01)。结论目标性监测方法能提高医院感染的发现率,为有效地采取医院感染控制措施提供更可靠的依据。

Incidence of Nosocomial Infection with Objective Monitoring Method and Prospective Overall Monitoring Method:A Comparison

OBJECTIVE By investigating the incidence of nosocomial infection with objective monitoring method and prospective overall monitoring method, to analyze the advantage and significance between two methods. METHODS Using the objective monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2003 and using the prospective overall monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2002. All data were analyzed with Stata 7.0 soft. RESULTS There were 100 cases occurring nosocomial infection in 267 neurosurgical operation patients. The patient incidence of nosocomial infection was 37.5% and the rate of nosocomial infection cases was 50.9% with objective monitoring method, that was significant higher than those data coming from May to December in 2002 with 248 cases under prospective overall monitoring method, with which the patient incidence of nosocomial infection and the rate of nosocomial infection cases were 20.2%(50 cases ) and 21.4%(53 cases), respectively . Statistically significant difference was found (P<0.01). CONCLUSIONS Objective monitoring method is a more useful measure than prospective overall monitoring method to rise the discovery rate of nosocomial infection, and to provide the foundation of controlling nosocomial infection.
