分析抗感染药物临床应用的某些特征和流行趋势，为医院药品管理和临床合理、有效、经济地用药提供参考。方法：以ＤＤＤ值为计量单位，对 １９９７和 １９９８年重医儿童医院药库药品实际出库进行统计分析，比较几类常用抗感染药及不同剂型的日均费用差异，计算抗感染药的日均费用期望值。结果：青霉素和头孢类抗感染药分别在使用频度及金额方面占主导地位；常用抗感染药的日均费用期望值为６．７２元。累计使用频度５％～８５％的日均费用在０．４７～１１．１９元内波动。
To analyze some characteristics and epidemiological trends of clinical application of anti-infectives, and to provide reference for hospital drug management and rational, effective and economical use of drugs in hospitals. Methods: Taking DDD value as the unit of measurement, statistical analysis was carried out on the actual outbound storage of drugstore children in 1997 and 1998 in hospitals, comparing the daily average cost of several commonly used anti-infectives and different dosage forms, and calculating the days of anti-infectives Expected cost of each. Results: Penicillin and cephalosporin antiinfective drugs were dominant in terms of frequency of use and amount, respectively. The expected daily average cost of common anti-infective drugs was 6.72 yuan. The cumulative average daily usage of 5% ~ 85% fluctuates within the range of 0.47 ~ 11.19 yuan.
