AbstractTraditional antibiograms can guide empiric antibiotic therapy, but they may miss differences in resistance across patient subpopulations. In this retrospective descriptive study, we constructed and validated antibiograms using International Classification of Disease, Tenth Revision (ICD-10) codes and other discrete data elements to define a cohort of previously healthy children with urinary tract infections. Our results demonstrate increased antibiotic susceptibility. This methodology may be modified to create other syndrome-specific antibiograms.

Susceptibility Patterns

Objectives: Urinary Tract Infections (UTIs) are the most common bacterial infections encountered in the Emergency Department (ED). Objectives of this study are to describe the urological pathogens associated with UTIs in the ED, report antibiotic susceptibilities, and assess empiric antibiotic treatment. Methods: A retrospective chart review of 154 patients with positive urine cultures from January to June 2016 were reviewed for inclusion in the study. Patients were excluded if less than 18 years of age, hospitalized, discharged from the ED without antibiotics or diagnosed with pyelonephritis. Patient demographics, uropathogens isolated, in-vitro susceptibility to commonly prescribed oral antibiotics (nitrofurantoin, ciprofloxacin, and sulfamethoxazole/trimethoprim), and antibiotics selected for treatment were recorded. Results: One hundred patients were included in the final analysis. Of the 106 bacterial isolates, Escherichia coli, Klebsiella pneumoniae, and Group B Streptococcus accounted for 62.5%, 8%, and 8% of pathogens, respectively. Overall susceptibilities were 88.1%, 87.9%, 85.4%, and 70.6% for nitrofurantoin, cefazolin, ciprofloxacin, and sulfamethoxazole/trimethoprim, respectively. Escherichia coli was most susceptible to nitrofurantoin at 96.9% followed by cefazolin at 94%. Ciprofloxacin was the most prescribed antibiotic followed by cephalexin, nitrofurantoin and sulfamethoxazole/trimethoprim. Conclusions: Based on bacterial susceptibility patterns, nitrofurantoin and cephalexin are reasonable first line agents in the empiric treatment of urinary tract infections identified in the emergency department. The most frequently prescribed antibiotic was ciprofloxacin, highlighting the importance of implementing antimicrobial stewardship initiatives and designing specific tools and educational programs for the emergency department targeted at minimizing fluoroquinolone use.

Background: Data regarding outpatient antibiotic prescribing for urinary tract infections (UTIs) are limited, and they have never been formally summarized in Virginia. Objective: We describe outpatient antibiotic prescribing trends for UTIs based on gender, age, geographic region, insurance payer and International Classification of Disease, Tenth Revision (ICD-10) codes in Virginia. Methods: We used the Virginia All-Payer Claims Database (APCD), administered by Virginia Health Information (VHI), which holds data for Medicare, Medicaid, and private insurance. The study cohort included Virginia residents who had a primary diagnosis of UTI, had an antibiotic claim 0–3 days after the date of the diagnosis and who were seen in an outpatient facility in Virginia between January 1, 2016, and December 31, 2016. A diagnosis of UTI was categorized as cystitis, urethritis or pyelonephritis and was defined using the following ICD-10 codes: N30.0, N30.00, N30.01, N30.9, N30.90, N30.91, N39.0, N34.1, N34.2, and N10. The following antibiotics were prescribed: aminoglycosides, sulfamethoxazole/trimethoprim (TMP-SMX), cephalosporins, fluoroquinolones, macrolides, penicillins, tetracyclines, or nitrofurantoin. Patients were categorized based on gender, age, location, insurance payer and UTI type. We used χ2 and Cochran-Mantel-Haenszel testing. Analyses were performed in SAS version 9.4 software (SAS Institute, Cary, NC). Results: In total, 15,580 patients were included in this study. Prescriptions for antibiotics by drug class differed significantly by gender (P < .0001), age (P < .0001), geographic region (P < .0001), insurance payer (P < .0001), and UTI type (P < .0001). Cephalosporins were prescribed more often to women (32.48%, 4,173 of 12,846) than to men (26.26%, 718 of 2,734), and fluoroquinolones were prescribed more often to men (53.88%, 1,473 of 2,734) than to women (47.91%, 6,155 of 12,846). Although cephalosporins were prescribed most frequently (42.58%, 557 of 1,308) in northern Virginia, fluoroquinolones were prescribed the most in eastern Virginia (50.76%, 1677 of 3,304). Patients with commercial health insurance, Medicaid, and Medicare were prescribed fluoroquinolones (39.31%, 1,149 of 2,923), cephalosporins (56.33%, 1,326 of 2,354), and fluoroquinolones (57.36%, 5,910 of 10,303) most frequently, respectively. Conclusions: Antibiotic prescribing trends for UTIs varied by gender, age, geographic region, payer status and UTI type in the state of Virginia. These data will inform future statewide antimicrobial stewardship efforts.Funding: NoneDisclosures: Michelle Doll reports a research grant from Molnlycke Healthcare.

Abstract Background Urinary tract infections (UTIs) are frequently caused by Enterococcus spp. We aim to define the risk factors involved in UTIs caused by Enterococcus. Determine the overall mortality and predictive risk factors. Methods A retrospective in-patients study was conducted with bacteriemic UTIs caused by Enterococcus spp. We compared bacteriemic UTIs caused by Enterococcus spp. vs. a random sample of 100 in-patients with bacteriemic UTIs caused by others enterobacteria. Results We found 106 in-patients with UTIs caused by Enterococcus spp., 51 of whom had concomitant positive blood cultures. Distribution by species was: 83% E. faecalis and 17% E. faecium, with a Charlson comorbidity index of 5.9 ± 2.9. When we compared bacteriemic UTIs caused by Enterococcus spp. vs. bacteriemic UTIs caused by others enterobacteria we found the following independent predictors of bacteriemic UTI by Enterococcus: male sex with an OR of 6.1 (95%CI 2.3–16.1), uropathy with an OR of 4.1 (1.6–10.1), nosocomial infection with an OR of 3.8 (1.4–10.3), urinary cancer with an OR of 6.4 (1.3–30.3) and previous antimicrobial treatment with an OR of 18 (5.2–62.1). Overall, in-patient mortality was 16.5%, which was associated with a higher Sequential Organ Failure Assessment (SOFA) score (> 4), severe comorbidity such as immunosuppression, malignant hemopathy and nephrostomy, or Enterococcus faecium species and its pattern or resistance to ampicillin or vancomycin (p < 0.05). Appropriate empiric antibiotic therapy was not associated with a better prognosis (p > 0.05). Conclusions Enterococcus spp. is a frequent cause of complicated UTI by a profile of risk factors. High mortality secondary to a severe clinical setting and high comorbidity may be sufficient reasons for implementing empiric treatment of patients at risk, although we did not show a higher survival rate in patients with this treatment strategy.

Objective: To validate the use of electronic algorithms based on International Classification of Diseases (ICD)-10 codes to identify outpatient visits for urinary tract infections (UTI), one of the most common reasons for antibiotic prescriptions. Methods: ICD-10 symptom codes (e.g., dysuria) alone or in addition to UTI diagnosis codes plus prescription of a UTI-relevant antibiotic were used to identify outpatient UTI visits. Chart review (gold standard) was performed by two reviewers to confirm diagnosis of UTI. The positive predictive value (PPV) that the visit was for UTI (based on chart review) was calculated for three different ICD-10 code algorithms using (1) symptoms only, (2) diagnosis only, or (3) both. Results: Of the 1087 visits analyzed, symptom codes only had the lowest PPV for UTI (PPV = 55.4%; 95%CI: 49.3–61.5%). Diagnosis codes alone resulted in a PPV of 85% (PPV = 84.9%; 95%CI: 81.1–88.2%). The highest PPV was obtained by using both symptom and diagnosis codes together to identify visits with UTI (PPV = 96.3%; 95%CI: 94.5–97.9%). Conclusions: ICD-10 diagnosis codes with or without symptom codes reliably identify UTI visits; symptom codes alone are not reliable. ICD-10 based algorithms are a valid method to study UTIs in primary care settings.

In Infants And Children

Urinary tract infections are one of the most common and serious bacterial infections in a pediatric population. So far, they have mainly been related to age, gender, ethnicity, socioeconomic level, and the presence of underlying anatomical or functional, congenital, or acquired abnormalities. Recently, both innate and adaptive immunities and their interaction in the pathogenesis and the development of UTIs have been studied. The aim of this study was to assess the role and the effect of the two most frequent polymorphisms of TLR4 Asp299Gly and Thr399Ile on the development of UTIs in infants and children of Greek origin. We studied 51 infants and children with at least one episode of acute urinary tract infection and 109 healthy infants and children. We found that 27.5% of patients and 8.26% of healthy children carried the heterozygote genotype for TLR4 Asp299Gly. TLR4 Thr399Ile polymorphism was found to be higher in healthy children and lower in the patient group. No homozygosity for both studied polymorphisms was detected in our patients. In the group of healthy children, a homozygote genotype for TLR4 Asp299Gly (G/G) as well as for TLR4 Thr399Ile (T/T) was showed (1.84% and 0.92 respectively). These results indicate the role of TLR4 polymorphism as a genetic risk for the development of UTIs in infants and children of Greek origin.
