Objective To evaluate the effect of class 10000 laminar flow ward on the incidence of healthcare-asso-ciated infection (HAI)in patients with initial occurrence of acute leukemia during induction chemotherapy period. Methods Patients with initial occurrence of acute leukemia admitted to a hematological department of a hospital be-tween October 2013 and June 2014 were investigated retrospectively,patients in class 10000 laminar flow ward was as trial group,in general ward was as control group. All patients received standard induction chemotherapy and the same nursing measures,the incidence of HAI between two groups of patients,and ward air cleanliness were com-pared.Results A total of 79 patients with initial acute leukemia were received (trial group,n= 39;control group, n= 40). The average air cleanliness value in rooms and corridors of laminar flow wards were both significantly dif-ferent with general ward (3.57×106/m3 vs 149.36×106/m3 ,t= 45.80,P<0.001;24.46×106/m3 vs 15854.38 ×106/m3 ,t= 108.70,P<0.001). Incidence of HAI between trial group and control group was significantly differ-ent (23.08% [9/39]vs 45.00% [18/40],χ2= 4.219,P= 0.040). The main infection site in trial group was gastro-intestinal tract (n= 5 ),in control group was lower respiratory tract (n= 8 ). The duration of fever,duration and cost of antimicrobial use in trial group were (6.20±2.10)d,(9.35±2.12)d,and (27113.79±1559.03)yuan re-spectively,in control group were (10.20±2.90)d,(14.15±3.14)d,and (58566.29±2217.54)yuan respectively, difference in duration of fever and cost of antimicrobial use between two groups were all significant(t= 1.021, 1377.45,both P<0.05).Conclusion Laminar flow ward can reduce the incidence of HAI in patients with initial occurrence of acute leukemia,and decrease cost of antimicrobial use.
