Abstract: Objective To investigate the incidence of healthcare-associated infection(HAI)in hospitalized patients≥65 years at a hospital in Hunan Province.Methods Data of patients with HAI in this hospital in 201 1—2013 were classified and analyzed statistically.Results A total of 47 626 patients were investigated,1 068 cases of HAI oc-curred,all cases were single site infection,incidence and case rate of HAI were both 2.24% ,incidence in patients aged <65 years (2-65 years old)was 0.98% (234/23 998),and ≥65 years was 3.53% (834/23 628),difference was significant between two groups (χ2= 354.44,P<0.001). HAI rate in patients aged <65,65~,70~,75~, 80~,85~,and ≥90 years was 0.98% ,1.59% ,1.28% ,2.77% ,5.20% ,6.93% ,and 9.43% respectively. The major infection site was lower respiratory tract (59.95% ,n= 500),the main detected pathogens were Pseudo-monasaeruginosa (19.43% )and Escherichia coil (18.72% ).Conclusion The incidence of HAI in the elderly patients increased with age increasing,the main infection site is lower respiratory tract.
