ABSTRACT
Objective To optimize antimicrobial use process,ensure the rational use of preoperative antimicrobial prophylaxis during consecutive operations.Methods Antimicrobial use process in a hospital in December 2015 was optimized,6 072 cases of consecutive operations in May-November 2015 were selected as control group,5 832 cases of consecutive operations in December 2015-May 2016 were as trial group,the qualified rate of rational use of antimicrobial agents was compared between two groups,causes for delayed/prior use was analyzed.Results Before and after the optimization of antimicrobial use process,rates of antimicrobial use were 77.16％ and 78.80％ respectively,there was significant difference between two groups(x2 =8.305,P =0.004).After the optimization of antimicrobial use process,rate of antimicrobial use within 0.5-1 hour was significantly higher than that before the optimization (82.36％ vs 41.11％);rate of antimicrobial use ＜0.5 hour before skin incision decreased from 57.11％ before optimization to 4.32％ after optimization;but rate of antimicrobial use ＞1 hour before skin incision increased from 1.78％ to 13.32％.Causes for delay/prior use of antimicrobial agents was due to the lack of effective communication between doctors and nurses,which resulted in circuit nurses' inaccurate assessment on interval of consecutive operations(62.13％),the duration of intubation or puncture was too long for anesthesiologists (13.57％).Conclusion Optimizing antimicrobial use process in consecutive operations can improve prophylactic antimicrobial use rate within 0.5-1 hour,and is helpful for ensuring the efficacy of antimicrobial prophylaxis.
