目的 分析天津醫(yī)科大學(xué)第二醫(yī)院住院患者特殊級(jí)抗菌藥物的使用情況，探討管理中存在的問題與對(duì)策，促進(jìn)臨床合理用藥。方法 采用回顧性分析法，通過HIS信息系統(tǒng)調(diào)取2015—2016年天津醫(yī)科大學(xué)第二醫(yī)院住院患者特殊級(jí)抗菌藥物的使用數(shù)據(jù)及資料，進(jìn)行比較分析。并使用魚骨圖探討特殊級(jí)抗菌藥使用中存在問題與對(duì)策。結(jié)果 2015—2016年特殊級(jí)抗菌藥物臨床使用率基本穩(wěn)定，特殊級(jí)抗菌藥物用藥頻度（DDDs）控制在合理范圍內(nèi)，注射用頭孢噻利、利奈唑胺注射液用量增長，科室分布變化不大，聯(lián)合用藥現(xiàn)象較為普遍，以2種藥物聯(lián)用為主，且聯(lián)合用藥呈下降趨勢。使用魚骨圖分析得出特殊級(jí)抗菌藥物臨床使用中存在藥物選擇、療程劑量、藥物配伍、聯(lián)合用藥4個(gè)方面問題。結(jié)論 天津醫(yī)科大學(xué)第二醫(yī)院特殊級(jí)抗菌藥物的使用較為合理，但也存在部分問題。需要通過醫(yī)師、藥師各司其職，依賴醫(yī)院行政干預(yù)，借助信息系統(tǒng)輔助管理，發(fā)現(xiàn)問題解決問題，使特殊級(jí)抗菌藥物臨床使用逐步合理。
