Abstract: ObjectiveThis study aimed at exploring the risk factors for bacter iemia.MethodsA 1:1 matched case-control study with 125 pairs on risk factors of bacter iemia was carried out in Fuzhou city in 1999.The available data were analyzed by Chisquare test and multiple logistic regression model.ResultsChisquare test showed that bacteriemia was significantly associated with long-time hospitalization,expose to intensive care unit,anemia,arteriovenous catheter,the other invasive diagnosis and treatment procedures,transfusion,unsuitable application of antibiotics, urinary catheter,application of immunoglobulin,and low albumin.The multivariable conditional logistic regression analysis showed that bacter iemia was significantly associated with long-time in hospitalization(with OR of 11.2,P<0.0001),arteriovenous catheter (with OR of 6.2,P<0.05),anemia(with OR of 6.0,P<0.0001),expose to intensive care unit(with OR of 3.5,P<0.01).ConclusionIt suggests that occurence of bacteriemia may correlate to long-time in hospitalization,arteriovenous catheter, anemia and expose to intensive care unit.
