Abstract:
Objective To investigate the characteristics and risk factors of hospital infection in elderly patients with acute leukemia and provide basis for its prevention and treatment. Methods The hospital infection rate,infection sites,pathogenic bacteria and infectious factors of 116 elderly patients with acute leukemia between January 1999 and January 2008 were analyzed retrospectively,and compared with groups of non-elderly patients in the corresponding period. Results The incidence of hospital infection [62.9 %(73/116)]and death[52.1 %(38/116)]in elderly patients were higher than that of non-elderly ones (P <0.01). The most commonly infective sites were oral cavity and respiratory system. The multiple and serious infection in elderly patients was more than that of non-elderly noes. The common pathogenic bacteria were mainly grant-negative one. The results of multivariate aralysis showed that the absolute neutrophil count in peripheral blood,cycles of chemotherapy,latest infections,stages of treatment,length of hospitalization and seasons on hospitalization were found as independent risk factors for hospital infection in elderly patients with acute leukemia. Conclusion The incidence of hospital infection and death in elderly patients was high. The absolute neutrophil count in peripheral blood,cycles of chemotherapy,latest infections,stages of treatment,length of hospitalization and seasons on hospitalization are independent risk factors for elderly patients with acute leukemia.
