摘要
目的探讨骨科住院患者合并医院感染的特征及预防对策,以降低医院感染率。方法回顾性分析2470例骨科患者的临床资料,观察医院感染发生率、部位、病原菌分布及感染对预后的影响。结果发生医院感染90例,感染率为3.64%,感染部位分别为呼吸系统40例占44.44%、泌尿系统16例占17.78%、消化系统14例占15.56%、穿钉部位11例占12.22%、切口9例占10.00%;80例进行病原菌培养,培养出53株病原菌,前3位病原菌依次为凝固酶阴性葡萄球菌15株、金黄色葡萄球菌12株、铜绿假单胞菌8株,检出耐甲氧西林葡萄球菌(MRS)34株,检出率为64.15%;年龄大、预防应用抗菌药物、侵入性操作、住院时间长是医院感染的危险因素;医院感染组死亡率为8.89%,高于未发生医院感染的1.47%(P<0.05)。结论骨科住院患者常合并一定程度的医院感染,可加重病情,其发生发展与多种因素相关,应针对相关特点实施干预。
Abstract. OBJECTIVE To explore the characteristics of nosocomial infections in the hospitalized patients of orthopedics department so as to put forward the prevention countermeasures. METHODS The clinical data of 2470 cases of orthopaedic patients were retrospectively analyzed, the incidence of nosocomial infections, infection sites, distribution of pathogens,and the influence on prognosis were observed. RESULTS Nosocomial infections occurred in 90 cases of patients with the infection rate of 3. 64%. There were 40 （44. 44%） cases of patients with respiratory system infections,16 （17.78%）cases of patients with urinary system infections, 14 （15.56%） cases of digestive system infections, 11 （12.22%） cases of puncture site infections, and 9 （10.00%） cases of patients with incision infections. Totally 53 strains of pathogens were cultured from 80 cases of patients, the top three species of pathogens were Staphylococcus aureus （12 strains）, Pseudomonas aeruginosa （8 strains）, and methicillin- resistant S. aureus （34 strains）, the drug resistance rates of which were 64.15%. The advanced age, prophylactic use of antibiotics, invasive operation, and prolonged hospital stay were risk factors for the nosocomial infections. The mortality of the patients with nosocomial infections was 8. 89%, higher than 1. 47% of those without nosocomial infections （P 〈0. 05）. CONCLUSION The nosocomial infections in the orthopedic patients can aggravate the illness, multiple factors involving the development and incidence, thus it is necessary to take corresponding interventions by aiming at the related characteristics.
