目的:探讨外科病房医院感染的相关危险因素,为临床的外科病房进行医院感染的防控提供理论支持。方法:选取本院外科病房住院进行手术治疗的8046例患者作为本研究的研究对象,其中发生医院感染253例,采用目标监测的调查研究方法,对患者进行医院感染相关危险因素的问卷调查,对外科病房医院感染相关危险因素进行单因素和多因素非条件Logistic回归分析。结果:单因素Logistic回归分析发现年龄、治疗专科(心胸外科)、治疗专科(神经外科)、入住ICU病房、急诊手术、住院治疗天数、气管插管全麻醉、切口类型(污染切口)、切口长度、侵袭性操作、侵袭性操作时间、抗菌药物治疗、术前抗菌药物治疗、术前抗菌药物治疗时间、术后抗菌药物治疗、术后抗菌药物治疗时间是医院感染的相关危险因素(P<0.05)。多因素Logistic回归分析发现年龄、治疗专科(心胸外科)、治疗专科(神经外科)、入住ICU病房、急诊手术、住院治疗天数、切口类型(污染切口)、切口长度、侵袭性操作、侵袭性操作时间、抗菌药物治疗均是医院感染的相关危险因素(P<0.05)。结论:外科病房医院感染是多种因素共同作用的结果,要针对外科病房医院感染相关危险因素制订相应的防治对策,对于降低医院感染率、防控外科病房医院感染的发生具有重要的意义。
Objective: To investigate the risk factors associated with nosocomial infection in surgical ward and to provide theoretical support for prevention and control of nosocomial infection in clinical surgical wards. Methods: Totally 8046 patients hospitalized for surgical treatment in our hospital were selected as the study subjects. 253 cases of nosocomial infection occurred. A questionnaire survey of risk factors related to nosocomial infection was conducted by using the method of target monitoring. Surgical ward hospital-related risk factors associated with univariate and multivariate non-conditional logistic regression analysis. Results: Logistic regression analysis showed that age, treatment specialties (cardiothoracic surgery), treatment specialties (neurosurgery), admission ICU ward, emergency surgery, hospitalization days, total tracheal intubation, incision type (incision), incision length , Aggressive operation, aggressive operation time, antimicrobial treatment, preoperative antibiotic treatment, preoperative antibacterial treatment time, postoperative antibacterial drug treatment, postoperative antibacterial drug treatment time were related risk factors of nosocomial infection (P <0.05 ). Multivariate logistic regression analysis found that age, treatment specialist (cardiothoracic surgery), treatment specialist (neurosurgery), ICU ward, emergency surgery, hospitalization days, incision type (incision), incision length, aggressive operation, aggressive operation Time, antimicrobial treatment are related risk factors for nosocomial infection (P <0.05). Conclusions: Hospital ward infection in surgical ward is the result of many factors. It is of great significance to develop appropriate prevention and control measures for the risk factors associated with nosocomial infection in surgical wards, which is of great significance to reduce the hospital infection rate and prevent and control the occurrence of nosocomial infection in surgical wards.
