Some risk factors make trau- matic patients susceptible to infection. Furthermore, some mortality risk factors, including length of hos- pitalization and increasing age, were detected in non-traumatic infected patients. This study aimed to assess mortality risk factors among nosocomial infected traumatic patients in Rajaee trauma center, Shiraz, Iran. Methods： This prospective cohort study was conducted during a period of 2 years since April 2015 to March 2017 in Rajaee hospital, which is the center of emergency medical services for traumatic injuries in Shiraz, Iran. Centers for Disease Control and Prevention/National Healthcare Safety Network surveil- lance system criteria were applied to define 5 types of nosocomial infections. The variables analyzed as the risk factors of infection and mortality included sex, age, mechanism of injury, site of injury, injury severity score （ISS）, surgical intervention, length of hospitalization, intensive care unit （ICU） admission, and type of pathogen. Then, the incidence of nosocomial infection and also risk factors of mortality in traumatic patients were evaluated. All data analyses were performed using the statistical package for social sciences, version 15 （SPSS Inc., Chicago） and p 〈 0.05 is considered to be statistically significant. Results： The incidence of nosocomial infection was 7.2% （p 〈 0.001）. Pneumonia was the most common type of infection detected in our study. Infection led to a 7.8-fold increase in mortality of the traumatic patients （p 〈 O.001 ）. Admission in intensive care units and old age were the main risk factors of mortality in infected traumatic patients. Old age, gunshot and motor vehicle accidents, trauma to extremities and abdomen, higher injury severity score, and prolonged hospitalization, made the traumatic patients more susceptible to infection.展开更多
目的：探讨不同病原微生物的急性感染对小儿发热起始时间（beginning time of fever，BTF）的影响．方法：对满足临床要求的709例患儿进行病史采集、体检和相关检测等，以了解不同年龄、不同系统、不同感染原之间的关系及BTF的分布特点...目的：探讨不同病原微生物的急性感染对小儿发热起始时间（beginning time of fever，BTF）的影响．方法：对满足临床要求的709例患儿进行病史采集、体检和相关检测等，以了解不同年龄、不同系统、不同感染原之间的关系及BTF的分布特点．结果：不同年龄患儿各系统暴露及各系统感染原类型无差别，但不同病原所致BTF分布时段不同，细菌感染者多出现在6：00～12：00时，病毒感染者多出现在18：00-24：00时，有统计学意义（P〈0．05）．结论：根据BTF可早期初步区别病毒和细菌感染．展开更多
