Characteristics and risk factors of nosocomial infection in hospitalized acute ischemic stroke patients
Abstract：Objective To study the characteristics and risk factors of nosocomial infection in hospi-talized acute ischemic stroke (AIS) patients .Methods One hundred and twenty-two hospitalized AIS patients were divided into nosocomial infection group (n=33) and non-nosocomial infection group (n=89) .Their clinical data were retrospectively analyzed and the infection time ,site ,patho-gens ,mortality were compared .Results Nosocomial infection occurred in patients 3 .7 ± 1 .6 days after admission .The most infection site was lower respiratory tract (63 .6% ) followed by upper respiratory tract (18 .2% )and urinary tract (21 .2% ) .The age was older ,the indidence of dyspha-gia and disturbance of consciousness was higher ,the indwelling time of catheter and gastric tube was longer ,the NIHSS score and the serum NT-proBNP level and the AIS volume were signifi-cantly higher in nosocomial infection group than in non-nosocomial infection group .The disturb-ance of consciousness and NIHSS score were the independent risk factors for nosocomial infection in AIS patients (P<0 .05 ,P<0 .01) .Of the 122 patients ,23 (18 .9% ) died including 18 in nosoco-mial infection group .The average hospital stay time of nosocomial infection group was significant-ly longer than that of non-nosocomial infection group (17 .8 ± 4 .1 d vs 12 .5 ± 5 .3 d ,P<0 .01) . Conclusion The incidence of nosocomial infection is still high in AIS patients .More attention should be paid to the risk factors for nosocomial infection in order to reduce its incidence .
