Abstract Objective: Overuse of antibiotics in the emergency department (ED) for uncomplicated acute respiratory tract infections (uARTIs) is a public health issue that needs to be addressed. We aimed to identify factors associated with antibiotic use for uARTIs in adults presenting at the ED. Design: We searched Medline, Embase, PsycINFO and the Cochrane Library for articles published from 1 January 2005 to 30 June 2017 using a predetermined search strategy. Titles and abstracts of English articles on antibiotic prescription and inappropriate antibiotic use for adult ARTI at EDs were assessed, followed by full article review, by 2 authors. Setting: Emergency departments. Participants: Adults aged 18 years and older. Results: Of the 2,591 articles retrieved, 12 articles met the inclusion criteria and 11 studies were conducted in the United States. Patients with normal C-reactive protein levels and positive influenza tests were less likely to receive antibiotic treatment. Nonclinical factors associated with antibiotic use were longer waiting time and perceived patient desire for antibiotics. Patients attended by internal medicine physicians comanaged by house staff or who visited an ED which provided education to healthcare providers on antibiotics use were less likely to receive antibiotics. Conclusions: English-language articles that fulfilled the selection criteria outside the United States were limited. Factors associated with antibiotics use are multifaceted. Education of healthcare providers presents an opportunity to improve antibiotic use.

AimThe aim of this study was to investigate occupational, environmental, early life, and other risk factors associated with respiratory infections and antibiotics use, in a general population and among asthmatics.MethodThis study included 15 842 participants of the RHINE study aged 25–54 years from five Nordic countries, who answered a questionnaire covering respiratory outcomes, exposures, demographic characteristics and numbers of infections and courses of antibiotics the last 12 months. Multiple logistic regression with and without adjustment for age, gender, smoking status, BMI and center were used to study the risk of infection and antibiotics in relation to asthma, and also the association between infection and antibiotics and occupations.ResultsIn the whole population, 11.6% reported having three or more respiratory infections, and 14.7% had used antibiotics because of respiratory tract infections within the last year. Asthmatics reported a tripled odd for such infections (adjusted OR (95% CI) 2.98 (2.53–3.52) and antibiotics use (adjusted OR 3.67 (3.18–4.24) as compared to non-asthmatics. Both in the general and the asthmatic population, female gender, obesity and exposure to building dampness were associated with respiratory infections. Female gender, and current smoking and living in Tartu were associated with antibiotic use. The use of antibiotics was doubled in people hospitalised for severe respiratory infection in childhood.ConclusionIn this study we identified several factors associated with increased respiratory infections and use of antibiotics in a general population and among asthmatics. The frequency of respiratory infections and subsequent antibiotic treatment were increased among asthmatics.

Tract Infections

Abstract Background Urinary tract infections (UTIs) are one of the most common bacterial infections. There is a lack of large epidemiologic studies evaluating the etiologies of UTIs in the United States. This study aimed to determine the prevalence of different UTI-causing organisms and their antimicrobial susceptibility profiles among patients being treated in a hospital setting. Methods We used the Premier Healthcare Database. Patients with a primary diagnosis code of cystitis, pyelonephritis, or urinary tract infection and had a urine culture from 2009- 2018 were included in the study. Both inpatients and patients who were only treated in the emergency department (ED) were included. We calculated descriptive statistics for uropathogens and their susceptibilities. Multi-drug-resistant pathogens are defined as pathogens resistant to 3 or more antibiotics. Resistance patterns are also described for specific drug classes, like resistance to fluoroquinolones. We also evaluated antibiotic use in this patient population and how antibiotic use varied during the hospitalization. Results There were 640,285 individuals who met the inclusion criteria. Females make up 82% of the study population and 45% were age 65 or older. The most common uropathogen was Escherichia Coli (64.9%) followed by Klebsiella pneumoniae (8.3%), and Proteus mirabilis (5.7%). 22.2% of patients were infected with a multi-drug-resistant pathogen. We found that E. Coli was multi-drug resistant 23.8% of the time; Klebsiella pneumoniae was multi-drug resistant 7.4%; and Proteus mirabilis was multi-drug resistant 2.8%. The most common antibiotics prescribed were ceftriaxone, levofloxacin, and ciprofloxacin. Among patients that were prescribed ceftriaxone, 31.7% of them switched to a different antibiotic during their hospitalization. Patients that were prescribed levofloxacin and ciprofloxacin switched to a different antibiotic 42.8% and 41.5% of the time, respectively. Conclusion E. Coli showed significant multidrug resistance in this population of UTI patients that were hospitalized or treated within the ED, and antibiotic switching is common.

Abstract Background Community-onset urinary tract infections (coUTIs) are one of the most common indications for antibiotic prescribing. It is important to understand patient demographic factors associated with microorganisms causing coUTI and their antibiotic resistance profiles, to tailor antibiotic prescribing practices. We analyzed microbiology data to understand factors associated with coUTI in the United States (US). Methods CoUTIs were identified in the Premier Healthcare Database and Cerner Health Facts among patients treated at participating healthcare facilities in the US between 2012-2017. Cases were defined by urine cultures yielding a bacterial organism and were collected in outpatient settings or within three days of hospitalization. Only the first specimen for each encounter was included in the analysis. Data on the organisms isolated, patient’s age, sex, and US census regions of the submitting facilities were described and compared using chi-square tests for associations. Encounters were classified as inpatient (INPT), observation (OBS), emergency department (ED), and outpatient (OTPT) based on the setting in which the culture was submitted. Results Using data from 637 acute care hospitals, urine samples from 3,291,561 encounters were included, with 776,653 (25.7%) INPT, 1,063,219 (34.8%) ED, 107,760 (3.5%) OBS, and 1,092,658 (35.8%) OTPT. The pathogens most frequently associated with coUTIs were Escherichia coli (57.3%), Klebsiella pneumoniae (9.7%), Enterococcus faecalis (5.1%), Proteus mirabilis (4.9%), and Pseudomonas aeruginosa (2.9%). Female sex, age < 65y and OTPT and ED settings were associated with higher relative frequency of E. coli (all p < 0.0001). Male sex, INPT setting and age >65 y were associated with higher relative frequency of P. aeruginosa, P. mirabilis and E. faecalis (all p < 0.0001, Figure). K. pneumoniae was found at higher relative frequency in those >45y, and in INPT and OBS settings (all p < 0.0001). Figure. Distribution of pathogens most frequently associated with community onset urinary tract infections Conclusion Understanding patient factors associated with the microbiology of coUTIs is an important step in developing treatment recommendations and antibiotic stewardship efforts. Further analyses will include assessing the impact of major antibiotic resistance phenotypes, geographic and healthcare settings. Disclosures All Authors: No reported disclosures

Abstract Background Ceftolozane–tazobactam (C/T) is an antipseudomonal cephalosporin combined with a β-lactamase inhibitor. The combination was cleared by FDA and EMA and is approved in the United States and over 60 countries worldwide. Using clinical isolates collected in the United States and Canada as part of the global SMART surveillance program, we compared the activity of C/T and ceftazidime–avibactam (CAZ/AVI) against P. aeruginosa isolates and subsets nonsusceptible (NS) to selected antimicrobial agents. Methods In 2018, 31 clinical laboratories from United States and Canada collected up to 250 consecutive, aerobic or facultatively anaerobic, Gram-negative pathogens (GNP) from blood, intra-abdominal, urinary, and lower respiratory tract infections. A total of 6,178 GNP were collected, of which 1,138 (18.4%) were P. aeruginosa. MICs were determined using CLSI broth microdilution and interpreted with CLSI 2019 breakpoints. Results The MIC distributions of C/T and CAZ/AVI against 1,138 P. aeruginosa are shown below. The modal MIC value for C/T was ≥2 doubling dilutions lower than that for CAZ/AVI, and it was ≥3 dilutions lower than the C/T CLSI susceptible breakpoint, whereas the modal MIC value for CAZ/AVI was 2 dilutions lower than its susceptible breakpoint. Among all P. aeruginosa isolates, percentages of susceptibility were 96.0% (C/T), 93.8% (CAZ/AVI), 76.6% (CAZ and cefepime), 67.0% (imipenem [IMI]), 74.0% (meropenem [MEM]), 71.5% (piperacillin–tazobactam [TZP]), and 64.9% (aztreonam). Among subsets of nonsusceptible isolates, susceptibilities to C/T and CAZ/AVI were 83.5% and 74.4%, respectively (CAZ-NS subset, n = 266), 91.0% and 85.1% (IMI-NS, n = 376), 87.5% and 80.1% (MEM-NS, n = 296), 87.0% and 79.6% (TZP-NS, n = 324), and 72.4% and 57.8% among isolates nonsusceptible to all tested β-lactams (n = 116). Conclusion The activity of C/T exceeded that of CAZ/AVI and other tested comparators against a recent collection of clinical isolates of P. aeruginosa, including subsets of isolates nonsusceptible to other β-lactams. Susceptibilities to C/T were 6–14 percentage points higher than observed for CAZ/AVI among β-lactam-NS subsets. C/T promises to be an important treatment option for patients with antimicrobial-resistant P. aeruginosa infections. Disclosures All authors: No reported disclosures.

Abstract Background Acute gastroenteritis (AGE) is a major cause of office and emergency department (ED) visits in the United States. Most patients can be managed with supportive care alone, although some require antibiotics. Limiting unnecessary antibiotic use can minimize side effects and the development of resistance. We used national data to assess antibiotic prescribing for AGE to target areas for stewardship efforts. Methods We used the 2006–2015 National Hospital Ambulatory Medical Care Survey of EDs and National Ambulatory Medical Care Survey to describe antibiotic prescribing for AGE. An AGE visit was defined as one with a new problem (<3 months) as the main visit indication and an ICD-9 code for bacterial or viral gastrointestinal infection or AGE symptoms (nausea, vomiting, and/or diarrhea). We excluded visits with ICD-9 codes for Clostridium difficile or an infection usually requiring antibiotics (e.g., pneumonia). We calculated national annual percentage estimates based on weights of sampled visits and used an α level of 0.01, recommended for these data. Results Of the 12,191 sampled AGE visits, 13% (99% CI: 11–15%) resulted in antibiotic prescriptions, equating to an estimated 1.3 million AGE visits with antibiotic prescriptions annually. Antibiotics were more likely to be prescribed in office AGE visits (16%, 99% CI: 12–20%) compared with ED AGE visits (11%, 99% CI: 9–12%; P < 0.01). Among AGE visits with antibiotic prescriptions, the most frequently prescribed were fluoroquinolones (29%, 99% CI: 21–36%), metronidazole (18%, 99% CI: 13–24%), and penicillins (18%, 99% CI: 11–24%). Antibiotics were prescribed for 25% (99% CI: 8–42%) of visits for bacterial AGE, 16% (99% CI: 12–21%) for diarrhea without nausea or vomiting, and 11% (99% CI: 8–15%) for nausea, vomiting, or both without diarrhea. Among AGE visits with fever (T ≥ 100.9oF) at the visit, 21% (99% CI: 11–31%) resulted in antibiotic prescriptions. Conclusion Patients treated for AGE in office settings were significantly more likely to receive prescriptions for antibiotics compared with those seen in an ED, despite likely lower acuity. Antibiotic prescribing was also high for visits for nausea or vomiting, conditions that usually do not require antibiotics. Antimicrobial stewardship for AGE is needed, especially in office settings.

ABSTRACT A total of 986 isolates of Haemophilus influenzae from patients with respiratory tract infections in 45 United States medical centers were characterized during the winter of 2002-2003. β-Lactamase production was noted with 26.2% of isolates; 14.6% were resistant to trimethoprim-sulfamethoxazole. Resistance to other relevant antimicrobial agents was extremely uncommon. In comparison to the results of four previous national surveys conducted since 1994, the prevalence of β-lactamase production with this pathogen appears to be decreasing.
