【摘要】 目的 验证临床药师对外科预防使用抗菌药物进行干预的效果。 方法 以临床药师督查记录数据为基础，将2010年1-3月238份病历设为非干预组，2010年10—12月240份病历设为干预组，建立评价标准，进行回顾性汇总、分析。 结果 通过干预，抗菌药物使用率从干预前的100%下降为77.08%（χ2=63.633，P=0.000），抗菌药物联用情况减少（χ2=53.712，P=0.000），用药时机和用药疗程有了较大改善，抗菌药物费用下降（t=-5.235，P=0.000），住院医疗费用降低（t’=-12.280，P=0.000），住院天数减少（t=-5.071，P=0.000）。 结论 临床药师通过实施合理用药干预对促进医院安全、有效、经济使用抗菌药物起到了积极作用。【Abstract】 Objective To verify the effect of clinical pharmacists’ intervention in antibiotics used for Type I incision surgical prevention. Methods Based on the supervision and inspection recording data of clinical pharmacists, we arranged 238 medical records in the first quarter of 2010 as non-intervened group and 240 medical records in the fourth quarter of 2010 as intervened group, and then established evaluation criteria and conducted a retrospective study for analysis. Results Through intervention, the rate of using antibiotics decreased from the previous 100% to 77.08% (χ2=63.633, P=0.000), the use of combined antibiotics also decreased (χ2=53.712, P=0.000), the time of course of using antibiotics improved, medical expenses of the antibiotics were reduced (t=-5.235, P=0.000), hospitalization cost decreased (t=-12.280, P=0.000), and hospital stay was shortened (t=-5.071, P=0.000). Conclusion Clinical pharmacists’ intervention in rational use of drugs play a positive role in contribution to a safe, effective and economical application of antibiotics.
