2002年～2004年我院抗菌药物的使用与细菌耐药性分析

目的:探讨我院抗菌药物使用量与细菌耐药性之间的关系。方法:统计2002年～2004年5类抗菌药物的用药频度,并对用药频度和细菌耐药性进行分析。结果:3年来抗菌药物的总用药频度值增长了47.14%;2004年,4种主要病原菌对9种常用抗菌药物的耐药率大于44%;阿莫西林/克拉维酸钾、氨苄西林钠/舒巴坦钠、头孢哌酮钠/舒巴坦钠3年来用药频度分别增长4倍、19.8倍、7倍,病原菌对其耐药率也明显提高,其中金黄色葡萄球菌的耐药率增加22%以上。结论:医院应多方面加强抗菌药物使用管理,减少细菌耐药性的发生。

Analysis on Antibacterial Drug Use and Bacterial Drug Resistance between 2002 and 2004

OBJECTIVE:To discuss the correlation between antibacterial drug use and the bacterial drug resistance in the hospital where the authors work.METHODS:The DDDs of antibacterials during the period from2002to2004were counted,and the correlation between DDDs and bacterial drug resistance was analyzed.RESULTS:The total DDD of the antibacterials increased by47.14%in this period.To2004,the resistance rates of4major pathogens to9commonly used categories of antibacterials were more than44%.The DDDs of amoxicillin/clavulanate potassium,ampicillin sodium/sulbactam sodium,cefoperazone sodium/sulbactam sodium increased by4,19.8and7times,respectively in the3years,the resistance rates of pathogens to which also evidently increased,among which staphylococcus aureus increased by over22%.CONCLU_ SION:The hospital should strengthen the administration of antibacterial drug use in many ways to reduce the bacterial drug resistance.
