目的研究胸外科手术患者医院感染发生现状及其影响因素。方法采用前瞻性研究方法,对某三级甲等教学医院胸外科所有进行手术患者的医院感染及其影响因素进行调查与分析。结果发生医院感染的胸外科手术患者住院天数明显高于未发生医院感染的胸外科手术患者,差异有统计学意义(P<0.05),胸外科手术患者医院感染发生率在住院天数方面差异有统计学意义(P<0.05)。结论住院天数对医院感染发生率和发生密度有较大影响,控制住院天数有助于降低医院感染发生率和发生密度。
Objective To study the status of nosocomial infection in thoracic surgery patients and its influential factors. Methods A prospective study was conducted to investigate and analyze the prevalence of nosocomial infections and their influencing factors in all thoracic surgical departments in a tertiary teaching hospital. Results The number of days of hospitalization for thoracic surgery patients with nosocomial infection was significantly higher than that of patients without thoracic surgery for nosocomial infection (P <0.05). The incidence of nosocomial infections in patients undergoing thoracic surgery was statistically different from that of hospitalization days Significance (P <0.05). Conclusions Hospitalization days have a significant impact on the incidence and incidence of nosocomial infections. Controlling the number of days of hospitalization helps to reduce the incidence and the occurrence of nosocomial infections.
