Characteristic and vulnerable factors of nosocomial infection in patients with malignant hematologic disease

Objective To explore the characteristic and vulnerable factors of nosocomial infection in patients with malignant hematologic disease. Methods The clinical data of 208 patients with malignant hematologic disease were studied retrospectively. Results Nosocomial infection occurred in 102 patients, with 17 cases of multiple sites infection. 18 patients died of infection. Infection often located on oral mucosa and respiratory tract mucosa. Gram negative bacteria and fungi were the common pathogens. Chemotherapy, leucocytopenia , usage of broad - specrtum antibiotic, long hospitalization were the vulnerable factors of nosocomial infection. Conclusion Patients with malignant hematologic disease should be monitored closely, and those with leucocytes less than 2 × 109 be isolated protectively. Rational application of antibiotics should be emphasized.
