RESUMEN
Bacterial infection is the main cause of infectious diseases in children. Antibacterials play an important role in anti infection treatment of children. At present, the treatment of antimicrobial drugs in children is facing a severe situation of bacterial resistance. In January 2020, a children′s specialized hospital carried out the practice of precise management of antibiotics in combination with key performance indicators. Through the multi sectoral linkage of management and technology, eight key performance indicators and assessment methods were set up from three levels of antibiotic use, bacterial resistance and hospital infection, to standardize the clinical application of antibiotics and continue to promote the rational use of antibiotics. This practice had improved the performance indicators of antibacterial management. Among them, the use intensity of antibacterial drugs for inpatients decreased from 40.07 DDD in 2019 to 29.00 DDD in 2021, the use rate of antibacterial drugs for inpatients decreased from 81.32% to 64.40%, the percentage of antibacterial drug expenses in total drug expenses decreased from 35.41% to 26.82%, the use proportion of non restricted antibacterial drugs in antibacterial drugs increased from 71.30% to 82.21%, and the drug resistance rate of Salmonella to β-Lactam/enzyme inhibitors decreased from 4.84% to 0.03%, and the incidence of hospital infection decreased from 1.16% to 0.96%. The precise management of antibiotics in combination with key performance indicators improved the level of rational use of antibiotics, effectively curbed bacterial resistance, achieved phased results, so as to provide a reference for the scientific management of antibiotics in children′s hospitals.
RESUMEN
OBJECTIVE： To provide reference for perioperative prophylactic use of antibiotics in urinary surgery department. METHODS： In response to irrational perioperative prophylactic use of antibiotics in urinary surgery department， taking type Ⅱ incision surgery and special diagnosis and treatment and preventive drug use as an example， the management and control mode for perioperative prophylactic use of antibiotics was established and intervened in urinary surgery department so as to intervene in antibiotics use through formulating surgical type risk classification system， forming perioperative medication clinical pathways such as type Ⅱ incision surgery and urinary calculi surgery with different infection risk， establishing tracking and supervision mechanism. The rationality indexes of perioperative prophylactic medication such as the rate of prophylactic antibiotics use were compared among related medical records collected from urinary surgery department within 3 months before and after intervention （186 records before intervention， 179 records after intervention）. Antibiotics use density （AUD） and amount of antibiotics in urinary surgery department were compared within 3 months before and after intervention to evaluate management and control effect. RESULTS： Among surveyed medical records， compared with before intervention， the rate of prophylactic antibiotics use was decreased from 97.3％ （181/186） to 91.6％ （164/179）； the rate of rational drug selection was increased from 17.7％ （32/181） to 71.3％ （117/164）； correct rate of medication timing was increased from 9.9％ （18/181） to 32.3％ （53/164）； the rate of rational post-operative prevention course was increased from 17.1％ （31/181） to 37.2％ （61/164）， with statistical significance （P＜0.05 or P＜0.01）. Average AUD was deceased from 83 DDD to 70 DDD within 3 months after intervention， and the amount of antibiotics was decreased from 689 669.23 yuan to 531 040.11 yuan. CONCLUSIONS： Established management and control mode for perioperative prophylactic use of antibiotics in type Ⅱ incision surgery and special diagnosis and treatment and preventive drug use can effectively reduce the rate of prophylactic antibiotics， AUD and amount of antibiotics in urinary surgery department， and promote rational use of antibiotics during perioperative period.
RESUMEN
OBJECTIVE:To provide reference for rational use of antibiotics to treat Pseudomonas aeruginosa (PA) infection in the clinic. METHODS:Resistant rate of PA in our hospital during 2011-2015 were analyzed retrospectively. Antibiotics use densi-ty(AUD)of 10 commonly used antibiotics were analyzed statistically,and the correlation of resistant rate with AUD was investi-gated by Spearman correlation analysis. RESULTS:One thousaud and eleven strains of PA were isolated in our hospital during 2011-2014,detection rate of PA always occupied the top 5 place. Top 3 antibiotics in the list of AUD were levofloxacin,ceftazi-dime,cefoperazone sodium and tazobactam sodium. AUD of piperacillin sodium and tazobactam sodium,levofloxacin,ciprofloxa-cin and meropenem were positively correlated with resistant rate of PA(r were 1.000,0.900,1.000,1.000,P0.05). CONCLUSIONS:There is correlation between AUD of antibiotics and resistant rate of PA. It is of important significance to detect resistant rate of PA and the use of antibiotics regularly. Antibiotics should be selected cautiously in accordance with bacterial monitoring data,results of drug sensitivity tests,the amount and resistant rate of antibiotics,etc,in order to reduce resistant PA.
RESUMEN
Objective To investigate the drug resistance of Acinetobacter baumannii and antibiotics use density of all kinds of antibacterial drugs before and after special antibacterial drugs remediation , provide evidence for the follow-up intervention strategies . Methods The experimental results of detected 562 cases Acinetobacter baumannii and sensitivity test were analyzed in our hospital in 2011-2012 , combined with using of every type of antibacterial drugs on different time period .Results The number of bacteria detec-ted half year had no significant difference during 2011-2012 .The antibiotics use density of beta-lactam、fluroquinoloncs and aminogly-cosides declined 22.22(31.92%)、4.19(46.29%)、5.24(68.83%) respectively by special antibacterial drugs remediation .Beta-lactam resistance rates declined significantly to 25%~30%, fluroquinoloncs and aminoglycosides resistance rates also declined , from 50%of the critical point to 20%~30%in the second half of 2012 .Conclusion Standardization of antibiotics use density of various antibacterial drugs could help reduce bacterial resistance .
