心内科住院患者医院内感染的发病率及危险因素

Incidence and risk factors of nosocomial infections in hospitalized patients in internal medicine-cardiovascular department

目的:探讨心内科住院患者医院内感染的发病率及危险因素。方法:收治心内科住院患者1 544例,回顾性分析其临床资料。结果:出现医院感染92例(6.1%)。年龄、患病时间、血清蛋白水平、住院时间、侵入性操作、心功能分级以及预防性使用抗生素等与医院感染存在相关性,侵入性操作、心功能分级以及预防性使用抗生素是独立危险因素。结论:心内科患者出现医院感染与多种因素存在关系,其中侵入性操作、心功能分级以及预防性使用抗生素是独立危险因素。

Objective:To explore the incidence and risk factors of nosocomial infections in hospitalized patients in internal medicine-cardiovascular department.Methods:1544 hospitalized patients in internal medicine-cardiovascular department were selected,and clinical data were retrospectively analyzed.Results:92 patients(6.1%) had nosocomial infections.Age,duration of disease,serum protein levels,length of hospital stay,intrusive operation,cardiac functional grading,preventive use of antibiotics were associated with nosocomial infection;invasive procedures,cardiac functional grading,preventive use of antibiotics were the independent risk factors.Conclusion:Nosocomial infections in hospitalized patients in internal medicine-cardiovascular department were related to a variety of factors;invasive procedures,cardiac functional grading,preventive use of antibiotics were the independent risk factors.
