Abstract:ObjectiveTo analyze microbiology specimen submission in patients who received therapeutic antimicrobial use in a hospital for consecutive two years, and evaluate the clinical effect.MethodsPatients discharged from a hospital in 2014 and 2015 were as the studied subjects, microbiology specimen submission rates, days of antimicrobial use, detection of sterilesite specimens and so on in patients receiving therapeutic antimicrobial use were compared.ResultsMicrobiology specimen submission rate in patients receiving therapeutic antimicrobial agents in 2015 was higher than that of 2014 (51.81% vs 45.55%; χ2=308.31，P＜0.01）；the quartile of antimicrobial use in patients receiving therapeutic antimicrobial agents in 2015 was shorter than that of 2014(7［4，12］d vs 8［5，12］d; Z=-5.89，P＜0.01）；The percentage of sterilesite specimen submission in 2015 was higher than that of 2014 (37.69%［20 190/53 574］ vs 31.56%［17 050/54 025］; χ2=446.15，P＜0.05）.Constituent ratios of infection of respiratory system, urinary system, bloodstream, and central nervous system were 58.75%, 10.54%, 7.02%, and 0.58% respectively; among all detected specimens, constituent ratios of sputum, blood, urine and cerebrospinal fluid were 53.01%, 15.55%, 9.58%, and 1.64% respectively. ConclusionThe enhancement of microbiology specimen submission rate can shorten duration of antimicrobial use, clinical effect is obvious.
