The intervention involved a hospital-wide memo that educated providers on the overuse of urine culture testing and described criteria for appropriate inpatient urine culture ordering, along with monthly audit and feedback of urine culture orders.To assess the impact of the program, researchers at LAC + USC Medical Center compared inpatient urine culture orders and the CAUTI standardized infection ratio (SIR) in the baseline period (January 2018 to January 2019) and the period after implementation of the diagnostic stewardship intervention (March 2019 to January 2020).The results showed that inpatient urine culture orders dropped from an average of 509 per month in the baseline period to 280 per month after implementation, and the corresponding CAUTI SIR fell dramatically. There were no significant changes in the hospital’s observed mortality for all patients or those patients with urinary tract infections, indicating that the intervention was not associated with any detectable patient harm. In addition, the reduction in urine cultures led to a projected lab expenditure reduction of $920 to $3,910 per month.”We plan to continue measuring and sharing our hospital CAUTI SIR monthly, educating providers in grand rounds yearly, and educating nurse champions at our monthly CAUTI committee meeting,” the authors write.Oct 6 Clin Infect Dis abstract Peer comparison linked to reduced antibiotic prescribing at VA hospitalOriginally published by CIDRAP News Oct 6A peer comparison–based antibiotic stewardship intervention at a Veterans Affairs (VA) emergency department (ED) was associated with reductions in overall and unnecessary oral antibiotic prescribing, researchers reported yesterday in Antimicrobial Agents and Chemotherapy.In a prospective, observational cohort study, researchers with the VA Pittsburgh Healthcare System and the University of Pittsburgh evaluated oral antibiotic prescribing by ED physicians at the VA Pittsburgh Healthcare System before and after implementation of a peer comparison stewardship intervention.The intervention involved staff education and emails sent to each ED clinician that compared their antibiotic prescribing rate to that of their peers. The peer comparison intervention was conducted from January 2018 through June 2018, and the study compared oral antibiotic prescriptions during that period with prescriptions during the baseline period (June 2016 through December 2017).During the intervention period, antibiotic prescriptions decreased monthly by 10.4 prescriptions per 1,000 ED visits (P = 0.07), and the relative decrease in the trend of antibiotic prescriptions during the intervention period compared to baseline was 9.9 prescriptions per 1,000 ED visits per month (P= 0.07). The intervention was associated with a significant decrease in monthly amoxicillin-clavulanate and increase in cephalexin prescriptions. Also, decreasing trends in ciprofloxacin prescriptions during the baseline period were maintained during the intervention.Unnecessary antibiotic prescribing decreased from 55.6% to 38.7% (a 30.4% decrease, P = 0.003) during the intervention, while optimal prescribing increased from 21.6% to 29.3% (a 35.8% increase, P = 0.12).The authors note that while the intervention was associated with decreased overall and unnecessary antibiotic prescribing, rates of unnecessary prescribing remained high, and increases in the optimal prescribing did not reach statistical significance.”These findings suggest that additional interventions beyond education and peer comparison may be needed in EDs to decrease rates of inappropriate antibiotic prescribing,” they wrote.Oct 5 Antimicrob Agents Chemother abstract CARB-X to fund development of novel antibacterial for pneumoniaOriginally published by CIDRAP New Oct 5CARB-X announced today that it is awarding up to $2.5 million to GangaGen Biotechnologies of Bangalore, India, to develop novel antibacterial proteins to treat hospital-acquired and ventilator-associated pneumonia caused by Klebsiella pneumoniae.The money will fund preclinical development of klebicins, which are naturally occurring protein antibiotics that have shown potent activity against K pneumoniae in in vivo studies. Klebicins specifically target and kill K pneumoniae without harming beneficial bacteria in the microbiome.”We are delighted to receive CARB-X’s support to progress the klebicin programme,” GangaGen president Tanjore Balganesh said in a press release from CARB-X (the Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator). “K. pneumoniae is a hard-to-treat pulmonary pathogen resistant to many of the current antibiotics. Additionally, hypervirulent strains of the pathogen are being isolated in many parts of the globe.”GangaGen will be eligible for an additional $8.1 million in funding from CARB-X if project milestones are met.Since its launch in 2016, CARB-X has provided $252 million in funding to accelerate the development of 69 antibacterial products.Oct 5 CARB-X press releaselast_img
