Abstract Background Hospitalizations with complicated urinary tract infection (cUTI) in the United States have increased. Though most often studied as a subset of cUTI, catheter-associated UTI (CAUTI) afflicts a different population of patients and carries outcomes distinct from non-CA cUTI (nCAcUTI). We examined the epidemiology and outcomes of hospitalizations in these groups. Methods We conducted a cross-sectional multicenter study within the 2018 National Inpatient Sample (NIS) database, a 20% stratified sample of discharges from US community hospitals, to explore characteristics and outcomes of patients discharged with a UTI diagnosis. We divided cUTI into mutually exclusive categories of nCAcUTI and CAUTI. We applied survey methods to develop national estimates. Results Among 2 837 385 discharges with a UTI code, 500 400 (17.6%, 19.8% principal diagnosis [PD]) were nCAcUTI and 126 120 (4.4%, 63.8% PD) were CAUTI. Though similar in age (CAUTI, 70.1 years; and nCAcUTI, 69.7 years), patients with nCAcUTI had lower comorbidity (mean Charlson, 4.3) than those with CAUTI (mean Charlson, 4.6). Median (interquartile range [IQR]) length of stay (LOS) was 5 (3–8) days in nCAcUTI and 5 (3–9) days in CAUTI. Overall median (IQR) hospital costs were similar in nCAcUTI ($9713 [$5923–$17 423]) and CAUTI ($9711 [$5969–$17 420]). Though low in both groups, hospital mortality was lower in nCAcUTI (2.8%) than in CAUTI (3.4%). Routine discharges home were higher in nCAcUTI (41.5%) than CAUTI (22.1%). Conclusions There are >626 000 hospital admissions with a cUTI, comprising ~1.8% of all annual admissions in the United States; 4/5 are nCAcUTI. Because CAUTI is frequently the reason for admission, preventive efforts are needed beyond the acute care setting.

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.

Background.Over the past 2 decades, multiple interventions have been developed to prevent catheter-associated urinary tract infections (CAUTIs). The CAUTI prevention guidelines of the Healthcare Infection Control Practices Advisory Committee were recently revised.Objective.To examine changes in rates of CAUTI events in adult intensive care units (ICUs) in the United States from 1990 through 2007.Methods.Data were reported to the Centers for Disease Control and Prevention (CDC) through the National Nosocomial Infections Surveillance System from 1990 through 2004 and the National Healthcare Safety Network from 2006 through 2007. Infection preventionists in participating hospitals used standard methods to identify all CAUTI events (categorized as symptomatic urinary tract infection [SUTI] or asymptomatic bacteriuria [ASB]) and urinary catheter–days (UC-days) in months selected for surveillance. Data from all facilities were aggregated to calculate pooled mean annual SUTI and ASB rates (in events per 1,000 UC-days) by ICU type. Poisson regression was used to estimate percent changes in rates over time.Results.Overall, 36,282 SUTIs and 22,973 ASB episodes were reported from 367 facilities representing 1,223 adult ICUs, including combined medical/surgical (505), medical (212), surgical (224), coronary (173), and cardiothoracic (109) ICUs. All ICU types experienced significant declines of 19%–67% in SUTI rates and 29%–72% in ASB rates from 1990 through 2007. Between 2000 and 2007, significant reductions in SUTI rates occurred in all ICU types except cardiothoracic ICUs.Conclusions.Since 1990, CAUTI rates have declined significantly in all major adult ICU types in facilities reporting to the CDC. Further efforts are needed to assess prevention strategies that might have led to these decreases and to implement new CAUTI prevention guidelines.

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

Background: Clinical characteristics and outcomes for patients with intracerebral hemorrhage and underlying chronic kidney disease (CKD) are not well determined. We hypothesized rate adverse events and in-hospital mortality is higher in patients with intracerebral hemorrhage and underlying renal disease. Objective: To determine the Outcomes for intracerebral hemorrhage stroke patients with renal failure as comorbidity in the United States Methods: We analyzed the data from Nationwide Inpatient Sample (2009-2011) for all intracerebral hemorrhage stroke patients with or without renal failure as comorbidity. Patients were identified using the International Classification of Disease, Ninth Revision. Baseline characteristics, in-hospital complications including myocardial infarction), sepsis, pneumonia, deep venous thrombosis, urinary tract infections, and discharge outcomes (mortality, minimal disability, and moderate-to-severe disability) were compared between the two groups. All in-hospital outcomes were analyzed after adjusting for potential confounders using multivariate analysis. Results: Of the 33521 patients with intracerebral hemorrhage stroke, 3899 (11.6%) had renal failure as comorbidity. Patients with underlying renal disease were higher rates for in hospital complications like myocardial infarction (3.64% versus 2.03%, P≤.0001) , sepsis (5.82% versus 3.14%, P≤.0001) , pneumonia (6.92% versus 5.18%, P≤.0001) , deep venous thrombosis (1.67 % versus 1.17%, P≤ .0.0078) , urinary tract infections (16.41% versus 15.08%, P≤ 0.0293) and hypernatremia (8.62% versus 4.98%, P≤ <.0001). In multivariate analysis adjusted for baseline cormorbitdities and in hospital complications, intracerebral hemorrhage patients with underlying renal disease had higher in hospital mortality (OR 1.146 (95% confidence interval (CI) 1.058- 1.240p-value=0.0008) , while there is no statistically significant difference for minimal/moderate disability between two groups ( OR = 0.980 (95% CI 0.896- 1.072 p-value=0.6571). Conclusions: Intracerebral hemorrhage patients with underlying renal disease have higher rate of in hospital complications and mortality. Future prospective studies are indicated to study this finding.

Renal and genitourinary complaints are common presentations to the emergency department. Urinary tract infections are among the top three sites of infection in patients presenting to the emergency department. Nephrolithiasis is also a common reason for patients to present due to the severe associated pain. Greater than 20 million patients in the United States are diagnosed with a sexually transmitted infection yearly and many of these present to the emergency department due to the associated discomfort and related symptoms. Other conditions related to the renal and genitourinary systems, though less common, are important for emergency providers to be adept at managing.

Abstract Background ZTI-01 (fosfomycin for injection) is an investigational epoxide antibiotic with a differentiated mechanism of action (MOA) inhibiting an early step in bacterial cell wall synthesis. ZTI-01 has a broad spectrum of in vitro activity, including multidrug-resistant Gram-negative pathogens, and is being developed for the treatment of patients with complicated urinary tract infection (cUTI) and acute pyelonephritis (AP) in the United States. Methods ZEUS was a multicenter, double-blind, Phase 2/3 trial in hospitalized adults with cUTI and AP to evaluate safety and efficacy. Randomized patients received 6 g ZTI-01 q8h or 4.5 g IV piperacillin/tazobactam (PIP-TAZ) q8h for 7 days; patients with baseline bacteremia could receive up to 14 days; study continued to late follow-up (LFU, 26 ± 2 days). Oral step-down therapy was prohibited. ZTI-01 met the primary endpoint of noninferiority to PIP-TAZ. Secondary objectives included comparing clinical cure rates (assessed by investigator) in the modified intent-to-treat (MITT), microbiologic MITT (m-MITT), clinical evaluable (CE), and microbiologic evaluable (ME) populations at test-of-cure (TOC, Day 19 ± 2 days). Results There were 464 patients randomized who received study drug. In all populations, clinical cure rates at TOC were high and similar between treatment groups (&gt;90%) (table). Conclusion These results demonstrate consistent efficacy in multiple secondary efficacy populations for patients with cUTI and AP who were treated with either ZTI-01 or PIP-TAZ. If approved by FDA, ZTI-01 may provide a new IV option with a differentiated MOA for patients in the United States with serious Gram-negative infections. 95% confidence intervals (CIs, two-sided) were computed using a continuity-corrected Zstatistic.

Antibiotic Resistance Patterns

Abstract Background In response to increasing rates of antimicrobial resistance, carbapenems have become first-line treatments for many infections. This, in turn, fosters the potential for resistance (CR). Efforts to mitigate the emergence of CR through carbapenem-sparing strategies must rest on a fundamental understanding of antibiotic resistance patterns among commonly encountered pathogens. Therefore, we examined the microbiology of complicated urinary tract infections (cUTI) in hospitalized patients in the United States. Methods We performed a multicenter retrospective cohort study in the Premier database of approximately 180 hospitals, 2013–2018. Using an ICD-9/10-based algorithm we identified all adult patients hospitalized with cUTI and included those with a positive blood or urine culture. Patients with carbapenem-resistant organisms were excluded. We examined the microbiology and susceptibilities to common cUTI antimicrobials (third-generation cephalosporin [C3], fluoroquinolones [FQ], trimethoprim-sulfamethoxazole [TMP/SMZ], fosfomycin [FFM], nitrofurantoin [NFT], and triple-resistant [TR]) over time. Results Among 28,057 organisms from 23,331 patients, the 3 most common pathogens were E. coli (EC, 41.0%), K. pneumoniae (KP, 12.1%), and P. aeruginosa (PA, 11.0%). Among these organisms, resistance to C3 was 10.4% among PA, 12.6% KP and 48.9% EC. EC was most likely to exhibit resistance to all agents of interest, and demonstrated the highest resistance rate to TMP/SMZ (61.5%), and lowest to NFT (10.4%). In contrast, KP had the highest rate of resistance to NFT (27.9%) and lowest to FQ (4.9%). The lowest rate of resistance among PA was to TMP/SMZ (1.9%), and highest to C3 (10.4%). The prevalence of TR in 2013–2014 and 2017–2018, respectively, was 34.2% and 37.4% for EC, 11.8% and 14.2% for KP, and 7.0% and 4.6% for PA. Conclusion Among the most common pathogens isolated in hospitalized patients with cUTI, and particularly in EC, high and increasing single resistance and TR rates to common antimicrobials were evident, Current empiric treatment strategies may be insufficient against the growing threat of TR.
