Abstract:ObjectiveTo investigate risk factors for healthcareassociated infection(HAI) in patients with aneurysmal subarachnoid hemorrhage(aSAH) in the department of neurology of a hospital. MethodsClinical data of 47 patients with aSAH who were admitted to a hospital from January 2014 to January 2015 were retrospectively analyzed. ResultsOf 47 patients with aSAH, 17 developed 19 times of HAI, HAI rate was 36.17%, case infection rate was 40.43%. The main infection site was lower respiratory tract (n=17, 89.47%), followed by urinary tract (n=2,10.53%); 2 patients had both lower respiratory tract infection and urinary tract infection. 17 patients were performed pathogenic detection, 13 pathogenic isolates were isolated from 9 patients. Multivariate nonconditional logistic regression analysis revealed that risk factors for HAI in patients with aSAH were disturbance of consciousness (OR,24.878 [95%CI, 3.996-156.040]) and intensive care unit admission(OR,8.645 [95%CI, 1.419-52.670]). The prognosis of patients with HAI was poorer than those without HAI(Z=4.108,P<0.001). ConclusionPatients with aSAH are at high risk of HAI, it is necessary to take targeted prevention and control measures for reducing the occurrence of HAI and promoting good prognosis.
