IntroductionAntibiotic resistance is a serious and increasing worldwide threat to global public health. One of antibiotic stewardship programmes’ objectives are to reduce inappropriate broad-spectrum antibiotics’ prescription. Selective reporting of antibiotic susceptibility test (AST) results, which consists of reporting to prescribers only few (n=5-6) antibiotics, preferring first-line and narrow-spectrum agents, is one possible strategy advised in recommendations. However, selective reporting of AST has never been evaluated using an experimental design.Methods and analysisThis study is a pragmatic, prospective, multicentre, controlled (selective reporting vs usual complete reporting of AST), before-after (year 2019 vs 2017) study. Selective reporting of AST is scheduled to be implemented from September 2018 in the ATOUTBIO group of 21 laboratories for all Escherichia coli identified in urine cultures in adult outpatients, and to be compared with the usual complete AST performed in the EVOLAB group of 20 laboratories. The main objective is to assess the impact of selective reporting of AST for E. coli-positive urine cultures in the outpatient setting on the prescription of broad-spectrum antibiotics frequently used for urinary tract infections (amoxicillin-clavulanate, third-generation cephalosporins and fluoroquinolones). The primary end point is the after (2019)–before (2017) difference in prescription rates for the previously mentioned antibiotics/classes that will be compared between the two laboratory groups, using linear regression models. Secondary objectives are to evaluate the feasibility of selective reporting of AST implementation by French laboratories and their acceptability by organising focus groups and individual semi-structured interviews with general practitioners and laboratory professionals.Ethics and disseminationThis protocol was approved by French national ethics committees (Comité d’expertise pour les recherches, les études et les évaluations dans le domaine de la santé (TPS 29064) and Commission Nationale de l’Informatique et des Libertés (Décision DR-2018–141)). Findings of this study will be widely disseminated through conference presentations, reports, factsheets and academic publications and generalisation will be further discussed.Trial registration numberNTC03612297.

Abstract Background Urinary tract infections (UTIs) are the second most common reason for antibiotics in hospitalized patients, with most receiving broad-spectrum antibiotics (BSA) regardless of infection severity. The antimicrobial stewardship program (ASP) conducted a multimodal stewardship intervention targeting reduction in one BSA, ceftriaxone, and promoted narrow-spectrum antibiotics (NSA) such as cefazolin and cephalexin for uncomplicated UTIs. Methods Phase 1: In February 2018, the ASP created a pocket card (Figure 1) containing (1) a urinary antibiogram outlining the most common urine pathogens and their local susceptibility to NSA and (2) NSA guidelines for UTIs with 0–1 systemic inflammatory response syndrome (SIRS) criteria. ASP performed a daily prospective audit with feedback on all new orders of ceftriaxone and promoted prescription of NSA. Phase 2: In August 2018, a Best Practice Alert (BPA) in the electronic medical record (EMR) was designed to interrupt providers ordering ceftriaxone with the indication of a UTI, and prompted NSA prescription instead. Quarterly didactic sessions on UTI antibiotic use and BPA functionality were done. We compared antibiotics usage rates across the 3 study phases (pre-intervention, phase I and phase II) by computing rate ratios (RRs) using Poisson regression. Results Compared with pre-intervention, phase 1 resulted in a significant decrease in ceftriaxone DOT (RR: 1.06, CI: 1.03–1.09, P < 0.001) and ceftriaxone orders for UTI (RR: 1.14, P < 0.001) and an increase in cefazolin DOT (RR: 0.89, P = 0.029) and orders for UTI (RR; 0.12, P < 0.001). It also resulted in a significant increase in cephalexin DOT (RR: 0.92, P = 0.002) and orders for UTI (RR: 0.58, P < 0.001). In phase 2, an additional significant reduction in ceftriaxone DOT (RR: 1.04, CI: 1.01–1.08, P = 0.018) and orders for UTI (RR: 1.62, P < 0.001) and an increase in cefazolin DOT (RR: 0.96, P < 0.001) and orders for UTI (RR; 0.56, P < 0.001) occurred, when comparing phase I to phase 2. It also resulted in a decrease in cephalexin DOT (RR: 0.83, P < 0.001) and orders for UTI (RR: 0.70, P < 0.001). Conclusion A multimodal stewardship intervention using a pocket card with guidelines and urine antibiogram, and an EMR BPA successfully reduced BSA and increased NSA for treatment of uncomplicated UTIs.

The Impact

Abstract Background Our institution revealed Enterobacteriaceae with discordant cefazolin (CEF)-resistant / ampicillin-sulbactam (SAM) susceptible patterns (CRASS-P). This discordance could be from the multiple MIC cephalosporin breakpoint adjustments from CLSI. SAM has higher resistance for gram-negative bacteria compared with cephalosporins such as CEF which is confirmed by our antibiogram. We sought to understand if narrow-spectrum antibiotic choices for CRASS-P urinary tract infections (UTIs) led to clinical cure (CC). Methods We conducted a retrospective review from January 2018 to February 2019 of all CRASS-P Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae isolates from urine cultures. Patients with any symptom related to a UTI, urinalysis with >10 white blood cells/high-powered field, urine culture with >10,000 colony-forming units/mL, and receipt of an antibiotic were included. CC was defined as symptom resolution within 48 hours with no return to care within 28 days of the positive urinary culture. “Group A” included patients prescribed narrow-spectrum antibiotics such SAM, CEF, or an oral cephalosporin (OC) vs. broad-spectrum antibiotics such as ceftriaxone, quinolones or sulfa-medications (“Group B”). Results There were 960/1356 (70.8%) CRASS-P urinary isolates and 244 patients met inclusion criteria. Of 244 patients, 72 were in Group A and 172 were in Group B. There was no difference in the diversity of the 3 uropathogens, P = 0.34 (Table 1). Median age was 69±20.3 and 67.5±23.9 years for Group A and Group B, respectively, P = 0.23. Females accounted for 73.6% and 77.9% in Group A and B, respectively, P = 0.51. Overall, patients reached CC in 98.6% (71/72) of Group A patients, compared with 92.4% (159/172) of Group B patients, P = 0.07. Antibiotics used in treatment are outlined in Figure 1. UTI was associated with bacteremia for 2 patients in Group A and 4 patients in Group B (P = 0.84). Both patients in Group A reached CC and used AMC for treatment. However, 1 out of 4 patients did not achieve CC in Group B. Conclusion The use of SAM or OC can spare the broad-spectrum antibiotics use for CRASS-P UTIs as there was no statistical difference in CC between the two groups. The use of SAM with CRASS-P bacteremia secondary to UTI is possible; however, future studies are needed. Disclosures All authors: No reported disclosures.

Current Paradigm

The current paradigm of urinary tract infection (UTI) pathogenesis takes into account the contamination of the periurethral space by specific uropathogens residing in the gut, which is followed by urethral colonization and pathogen ascension to the urinary bladder. Consequently, studying the relationship between gut microbiota and the subsequent development of bacteriuria and UTI represents an important field of research. However, the well-established diagnostic and therapeutic paradigm for urinary tract infections (UTIs) has come into question with the discovery of a multifaceted, symbiotic microbiome in the healthy urogenital tract. More specifically, emerging data suggest that vaginal dysbiosis may result in Escherichia coli colonization and prompt recurrent UTIs, while urinary microbiome perturbations may precede the development of UTIs and other pathologic conditions of the urinary system. The question is whether these findings can be exploited for risk reduction and treatment purposes. This review aimed to appraise the three aforementioned specific microbiomes regarding their potential influence on UTI development by focusing on the recent studies in the field and assessing the potential linkages between these different niches, as well as evaluating the state of translational research for novel therapeutic and preventative approaches.
