Abstract:ObjectiveTo evaluate the effect of antimicrobial management guideline on the daily antimicrobial use rate in a general hospital.MethodsAn oneday pointprevalence survey on antimicrobial use in hospitalized patients was conducted in 2010, 2011,and 2012 by means of crosssectional investigation method.ResultsThe daily utilization rate of antimicrobial agents in 2010, 2011,and 2012 was 65.40%,42.09% and 26.74% respectively,the rate of the submission of specimens for bacterial culture was 22.53%, 35.74% and 41.74% respectively(χ2trend=266.42,29.02,respectively, both P<0.01). The utilization rate of single drug was 83.72%,80.27% and 93.41% respectively. the utilization rate of both twodrug and more than threedrug combination kept a downward tendency. The utilization rate of antimicrobial agents in several departments(digestive internal medicine,cardiovascular, hematological tumor,neurology, general surgery,orthopedics, obstetrics, pediatrics,and ophthalmology) showed a decreasing tendency(all P<0.01).ConclusionThe implementation of antimicrobial management guideline has remarkably reduced the daily antimicrobial use rate, and increased etiological detection rate for therapeutic antimicrobial use.
