Abstract:

AIM: To provide guidance for the reasonable clinical usage of antibacterial drugs by employing the partial least squares regression (PLSR) algorithm to analyze the correlation between the detection rate of carbapenem-resistant Klebsiella pneumoniae (CR-KP) and the utilization of antibacterial drugs.  METHODS: Different PLSR models were established with the defined daily doses (DDDs) of antibacterial drugs in different quarters as independent variables and the detection rate of CR-KP with same and different periods (lagged 1-4 quarters) as dependent variables. The lag time between the detection rate of CR-KP and the utilization of antibacterial drugs was investigated. The antibacterial drugs, which were highly correlated to the detection rate of CR-KP were screened. The influences of the antibacterial drugs on the detection rate of CR-KP were then investigated according to the regression coefficients. RESULTS:The detection rate of CR-KP lagged about two quarters behind the utilization of antibacterial drugs. It was significantly positively correlated with the DDDs of amoxicillin-clavulanic acid and sulbenicillin, while negatively correlated with the DDDs of itraconazole. The regression coefficients of amoxicillin-clavulanic acid, itraconazole and sulbenicillin were 0.085 2, -0.083 9 and 0.076 3, respectively. CONCLUSION: It is effective to employ PLSR algorithm to simultaneously analyze the correlation between the detection rate of CR-KP and the utilization of multiple antibacterial drugs, which provides a new scientific tool for controlling the detection rate of CR-KP.
