Risk factors of nosocomial infections in elderly patients of respiratory medicine department and intervention measures

OBJECTIVE To discuss risk factors of nosocomial infections in the elderly patients of respiratory medicine department and put forward intervention measures so as to guide the clinical prevention and treatment.METHODS A total of 1028cases of elderly patients who were treated in the respiratory medicine department were enrolled in the study and were divided into the infection group and the non-infection group,then the multivariate regression analysis of the risk factors was performed.RESULTS Of 1028cases of elderly patients,the nosocomial infections occurred in 116cases with the infection rate of 11.3%.The respiratory tract infections were most common,which were caused by fungi.In the infection group,there were 60(51.7%)cases of long-term bedridden patients,66(56.9%)cases of dysphagia patients,and 64(55.2%)cases of patients undergoing invasive operation,the level of albumin was(31.2±3.1)g/L;in the non-infection group,there were 310(34.0%)cases of long-term bedridden patients,400(43.9%)cases of dysphagia patients,and 400(43.9%)cases of patients undergoing invasive operation,the level of albumin was(40.8±4.1)g/L,the difference between the two groups was statistically significant(P0.05).The multivariate analysis showed that the long-term bedridden,invasive operation,and low level of albumin were the independent risk factors for the nosocomial infections in the elderly patients of the respiratory medicine department(P0.05).CONCLUSIONThe incidence of nosocomial infections in the elderly patients of the respiratory medicine department is closely related to the long-term bedridden,invasive operation,and low level of albumin,which are the independent risk factors;it is necessary for the hospital to carry out interventions to the risk factors discussed above.
