目的了解医院创伤外科患者医院感染现患率,为制订有效控制措施提供依据。方法采用横断面调查方法 ,对某医院创伤外科住院患者医院感染现患率进行了调查与分析。结果调查当日应查住院患者332例,实查325例,实查率97.89%。查出医院感染23例、28例次,医院感染现患率为7.08%、例次感染率为8.61%。感染部位以下呼吸道感染居首位,构成比为47.82%;其次为创面感染和泌尿系感染,构成比分别为21.74%和13.04%。感染病原菌以铜绿假单胞菌和金黄色葡萄球菌居多。抗菌药物使用率为47.08%。结论创伤外科患者医院感染发生率较高,创面和泌尿道感染率较高是创伤外科特点,应加强对复合创伤患者的院感因素评估,有针对性制定防控措施。 Objective To understand the prevalence of nosocomial infections in traumatic surgery patients in hospitals and provide the basis for effective control measures. Methods The cross-sectional survey method was used to investigate and analyze the prevalence of nosocomial infection in inpatients with traumatic surgery in a hospital. Results On the day of investigation, 332 inpatients should be investigated, 325 cases were investigated, and the actual examination rate was 97.89%. 23 cases were found nosocomial infection, 28 cases, the prevalence rate of hospital infection was 7.08%, the infection rate was 8.61%. The lowest respiratory tract infection was found in the infected area, with a ratio of 47.82%, followed by wound infection and urinary tract infection, with constituent ratios of 21.74% and 13.04%, respectively. Infectious pathogens mostly Pseudomonas aeruginosa and Staphylococcus aureus. Antimicrobial usage was 47.08%. Conclusion The incidence of nosocomial infection in traumatic surgery patients is high, and the rate of wounds and urinary tract infections is a traumatic surgical feature. Evaluation of nosocomial factors in patients with traumatic trauma should be strengthened, and prevention and control measures should be formulated.
