Abstract: Objective To evaluate the risk factors for healthcare-associated infection(HAI)in senile dementia pa-tients,so as to adopt effective nursing measures to reduce the incidence of HAI.Methods Clinical data of 82 senile dementia patients aged≥60 years and hospitalized between January 2011 and June 2013 were analyzed retrospective-ly.Results Of 82 patients,28 (34.15%)developed HAI.The main infection site was lower respiratory tract(n=15,53.57%),followed by urinary tract(n=6,21 .43%).Univariate analysis revealed that risk factors for HAI in senile dementia patients were bedridden,long length of hospital stay ,dysphagia,indwelling urinary catheter,irra-tional use of antimicrobial agents,combined with tumor,and hypoproteinemia (all P <0.05 ).The main isolated bacteria were gram-negative bacilli(n=40,62.50%),the top three pathogens were Klebsiella pneumoniae (n=12, 18.75%),Escherichia coli (n =10,15.63%),and Pseudomonas aeruginosa (n =8,12.50%).Conclusion Reali-zing the risk factors and common pathogens of HAI in senile dementia patients is helpful for taking effective meas-ures to prevent and control the incidence of HAI .
