目的：对我院１９９８年各种抗感染药物的使用频度及药品消耗金额进行计算并排序，分析各药物的临床地位。方法：以药物限定日剂量（ＤＤＤ）及消耗金额作为药物利用研究评价的测定单位，并进行比较。结果：按ＤＤＤｓ排前１０位的抗感染药分别为注射用头孢拉定、甲硝唑注射液、庆大霉素注射液、注射用头孢三嗪、头孢拉定胶囊、注射用卡那霉素、头孢氨苄胶囊、氟哌酸胶囊、环丙沙星片和注射用头孢哌酮。另外，还进行了消耗金额前１０位的排序，其中头孢菌素类６种，占抗感染药物消耗金额的９０９５％。结论：使用频度和消耗金额不成线性关系，二者较好地结合能指导临床用药。
Objective: To calculate and rank the frequency of use of various anti-infective drugs and the amount of drug consumption in our hospital in 1998, and analyze the clinical status of each drug. Methods: Drug-restricted daily dose (DDD) and consumption amount were used as measurement units for drug use research evaluation and compared. Results: The top 10 anti-infectives by DDDs were cefradine for injection, metronidazole injection, gentamicin injection, ceftriaxone for injection, cephradine capsules, kanamycin for injection, and cephalexin capsules. , Norfloxacin capsules, ciprofloxacin tablets and cefoperazone for injection. In addition, the top 10 rankings of consumption amount were also performed, among which 6 were cephalosporins, which accounted for 90.5% of the consumption of anti-infective drugs. Conclusion: The frequency of use and the amount of consumption are not linear, and the combination of the two can guide clinical medication.
