Abstract:
Objective To achieve refinement management of antibiotics by innovatively introducing relevant key indicators to control antibiotics use density (AUD).
Methods Based on the data of case mix index (CMI), the utilization rate of antibiotics in DIP system, and AUD in HIS system in a Class Ⅲ Grade A general hospital in East China from January to June 2021, the introduced key indicators were established and the optimal linear regression model was established. The non-integral rank method was used to rank and calculate. Rank-sum ratio (RSR) grading based on CMI adjusted AUD was compared with RSR grading based on AUD single assessment.
Results The RSR classification of AUD of 32 departments in the hospital was studied by introducing CMI values. It was found that the classification results of 12 departments changed, accounting for 37.5%, and the overall number of departments (classified as lower and middle level) in need of strengthening control increased. After the introduction of CMI to adjust AUD, control level raised in 7 departments and fell in 5 departments.
Conclusions The grading evaluation model of based on CMI and RSR is effective in the control of AUD in these departments.
