Analysis and countermeasures among 145 elderly patients with hospital infections in digestive department

目的探讨消化内科老年患者医院感染的发生率及危险因素等,提出针对性的预防医院感染的措施,降低老年患者医院感染的风险。方法通过前瞻性研究方法,组织专业的负责人员团队,通过在院记录及出院随访相结合的方式,对绍兴市立医院消化内科老年人的医院感染进行统计分析。结果 1 036例消化内科老年患者中,发生医院感染145例,感染率为14.00%。感染率会随着住院天数,侵袭性操作,长期卧床,使用激素等危险指数升高而升高。不同管床大夫的调整感染专率不同,差异具有统计学意义;发生感染的主要部位为下呼吸道及泌尿系,主要病原菌为肺炎克雷伯杆菌。结论消化内科老年患者医院感染的危险因素包括住院天数、长期卧床等,需在今后的临床治疗中引起注意。

Objective To explore the incidence and risk factors of hospital-acquired infections（HAI）in elderly gastroenterology patients,and propose appropriate measures of hospital infection control to reduce the risks of hospital-acquired infections in elderly patients.Methods Using aprospective study method,aprofessional team was organized,and a retrospective analysis study was performed on the elderly gastroenterology patients with hospital-acquired infections.Results The incidence of HAI in elderly gastroenterology patients was 14.00%（145/1036）.The infection risk index increased along with the increase of hospital stay,invasive operations,long-term bedridden and use of antibiotics or hormones.The doctor-specific infection rates were statistically different between doctors-in-charge.The main parts of HAI were lower respiratory tract and urinary system,and the main pathogen was Klebsiella pneumoniae.Conclusion The risk factors of hospital infections for elderly gastroenterology patients include hospitalization days,long-term bedridden and so on,which must be paid attention in future clinical treatment.
