Objective: To analyze hematology patients with nosocomial infection , blood diseases explore the characteristics of nosocomial infection , causing hospital infections causes and risk factors , to understand the distribution of pathogens , provide a scientific basis for clinical prevention . Methods: 2008 -2009 2303 inpatient hospital hematology clinical isolates of patients analyzing the distribution of pathogens , infection with the 2007 comparison . Results: The positive pathogens isolated were 220 cases . Respiratory tract infection site still ranks first , followed by blood , mouth, urinary tract and other parts.
