Abstract:
OBJECTIVE To investigate extended-spectrum ?-lactamases(ESBLs) producing bacteria and daily(defined) doses (DDDs) of the third generation cephalosporins.METHODS The cosumpsion of the third generation cephalosporins in five(hospitals) from 2000 to 2002 and the incidence of ESBLs producing bacteria were(analyzed).RESULTS In these years,the total DDDs were 1.3064 million therapeutic days,0.3335 million in 2000;0.4312 million in 2001;(0.5417) million in 2002.The average ESBLs producing ratio was 33.67%,ie,29.64%,32.58% and(38.45%) in 2000,2001 and 2002.CONCLUSIONS The incidence of ESBLs producing bacteria and DDDs of the third generation cephalosporins are raised gradually. More faster raised DDDs would result in higher incidence of ESBLs producing bacteria.
