Abstract:
Objective To compare the co-prescribing patterns of antibacterials between clinic and ER in a tertiary hospi-tal and mine the association rules among drugs in outpatient and emergency prescriptions .Methods The prescribing data of 2009 were sampled and the prescription drugs were classified according to the anatomical therapeutic chemical (ATC) subgroup code .IBM PASW ○R Modeler 14 was used for data processing and statistics ,and the Apriori association analysis model was es-tablished to carry out data mining .Results There were differences between outpatient and emergency prescriptions with anti-microbial in average number of drug items and antibacterials items ,as well as in the distribution of patient age and gender .Ex-pectorants ,cough suppressants and prepared Chinese medicine for “Qing Re Jie Du” played dominant roles in the associations with cephalosporin in outpatient prescription .More association rules in emergency prescriptions were found which were more complicated .The associations between antibacterials and vitamins ,digestive ulcer drugs ,and potassium agents ,as well as an-tibacterial and antibacterials were not found in the outpatient prescriptions .Conclusion The use of antibacterials in the emer-gency is much more frequently than in the clinic ,especially for the inject-able formulations and the combination of antibacteri-als .So it is more necessary to establish a standard for rational use of antibacterials in ER .
