OBJECTIVETo describe current practice around urine testing and identify factors leading to overtreatment of asymptomatic bacteriuria in community nursing homes (NHs)DESIGNObservational study of a stratified random sample of NH patients who had urine cultures ordered in NHs within a 1-month study periodSETTING31 NHs in North CarolinaPARTICIPANTS254 NH residents who had a urine culture ordered within the 1-month study periodMETHODSWe conducted an NH record audit of clinical and laboratory information during the 2 days before and 7 days after a urine culture was ordered. We compared these results with the urine antibiogram from the 31 NHs.RESULTSEmpirical treatment was started in 30% of cases. When cultures were reported, previously untreated cases received antibiotics 89% of the time for colony counts of ≥100,000 CFU/mL and in 35% of cases with colony counts of 10,000–99,000 CFU/mL. Due to the high rate of prescribing when culture results returned, 74% of these patients ultimately received a full course of antibiotics. Treated and untreated patients did not significantly differ in temperature, frequency of urinary signs and symptoms, or presence of Loeb criteria for antibiotic initiation. Factors most commonly associated with urine culture ordering were acute mental status changes (32%); change in the urine color, odor, or sediment (17%); and dysuria (15%).CONCLUSIONSUrine cultures play a significant role in antibiotic overprescribing. Antibiotic stewardship efforts in NHs should include reduction in culture ordering for factors not associated with infection-related morbidity as well as more scrutiny of patient condition when results become available.Infect Control Hosp Epidemiol 2017;38:524–531

Background: Guidelines regarding asymptomatic bacteriuria (ASB) have consistently recommended against screening and treatment in most circumstances. However, screening of patients with spinal cord injury (SCI) is common practice and in some cases is a formal protocol at the organizational level. A previous study found that more than one-third of patients with ASB detected on routine screening cultures performed at annual visits in 2012 received antibiotics. However, the role of antibiotic stewardship has become more prominent over the last decade. We hypothesized that diagnostic and therapeutic stewardship efforts may be impacting the practice of annual urine-culture screening for SCI patients. We evaluated urine culture screening and treatment rates over a 10-year period. Methods: Patients with SCI seen in the VA Boston HCS for an annual exam in 2018 were eligible for inclusion and formed the baseline cohort for this study. Annual visits for the cohort over a 10-year period (January 1, 2009–December 31, 2018) were included in the analysis. Electronic data collection and manual chart review were utilized to capture outcomes of interest including urine culture, antibiotic prescriptions and indication within 15 days, and documentation of urinary or infectious symptoms. The main outcomes were (1) rate of urine cultures performed ±3 days of the visit, (2) rate of antibiotic treatment in asymptomatic patients, and (3) trend over time of urine culturing and treating. The χ2 test for trend was used to compare rates over time. Results: In total, 1,962 annual visits were made by the 344 unique patients over the 10-year period and were available for analysis. Among these, 639 (32.6%) visits had a urine culture performed within 3 days. The proportion of visits with a collected culture decreased from (109 of 127) 85.8% of visits in 2009 to (65 of 338) 19.2% of visits in 2018, P ≤ .001 (Fig. 1). In the treatment analysis, 39 visits were excluded for active symptoms, concern for uncontrolled infection, or prophylaxis as antibiotic indication. Among 600 remaining screening cultures, 328 had a bacterial pathogen or >100,000 mixed colonies consistent with ASB. Overall, 51 patients (17%) received antimicrobials. The rate of antibiotic treatment for ASB did not significantly decrease over time pP = 0.79 (Fig. 2). Conclusions: Over a 10-year period of annual SCI visits, the proportion of visits with a urine culture performed as routine screening significantly and consistently decreased. However, the rate of treatment for positive urine cultures remained consistent. These data support targeted diagnostic stewardship in this population to reduce unnecessary antibiotic use.Funding: NoneDisclosures: None

Abstract Background The Infectious Diseases Society of America asymptomatic bacteriuria (ASB) guidelines recommend against screening for or treating ASB in most patients without symptoms of a urinary tract infection (UTI). The purpose of this study was to characterize current urine testing practices and their potential impact on identification and treatment of asymptomatic bacteriuria on hospitalized adults. Methods This retrospective, point prevalence study conducted at a 4 hospital community health-system that included all inpatients ≥ 18 years old present on November 13th, 2019. Patients were excluded if they were admitted or transferred to either a labor & delivery or mother-baby unit. A chart review was performed for a sub-group of patients with abnormal urine testing, with a target sample size of 200 (n=50 from each hospital). The primary outcome was the prevalence of patients with a urinalysis, urine culture, or both performed during their admission. Secondary outcomes included abnormal urine testing in the overall cohort and symptomatology and antibiotic use in the sub-group (Figure 1). Results 947 patients met inclusion criteria. Of those patients, 516 (54%) had urine testing performed during their admission. 322 (34%) patients had abnormal urine testing results (Table 1). In the sub-group, 192 patients with abnormal urine tests were included. Antibiotics with a documented indication of UTI were administered to 66 (34%) patients. Of those given antibiotics with a UTI indication, 49/66 (74%) did not have documented signs or symptoms of a UTI (Figure 2). Conclusion Urine testing was performed on the majority of admitted adult patients. Unnecessary testing likely contributes to guideline discordant screening and treatment of ASB. Future studies are needed to identify effective diagnostic stewardship interventions to decrease screening and treatment of ASB. Disclosures Ashley Wilde, PharmD, BCPS-AQ ID, Nothing to disclose

Introduction: Asymptomatic bacteriuria is the significant presence of bacteria in urine of an individual without symptoms. The aim of the study is to determine the prevalence of asymptomaticbacteriuria in pregnant women. Methods: This study was a prospective study conducted in the department of Obstetrics and Gynaecology at B. P. Koirala Institute of Health Sciences. The duration of the study was six monthsfrom January to June 2012. A total of 600 pregnant women were enrolled. All women were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collectedfrom each patient into a sterile vial. The urine samples were examined for microscopic and culture sensitivity test. Results: Out of 600 pregnant women, 52 were positive for significant bacteriuria with a prevalence rate of 8.7%. There was a significant difference in prevalence of asymptomatic bacteriuria withrespect to trimester (p=0.005). Age did not show any significant difference in the prevalence of asymptomatic bacteriuria (p=0.807). There was not any significant difference in the prevalence ofasymptomatic bacteriuria with respect to parity (p=0.864) and booking status (p=0.397). Escherichia coli (35%), Acinetobacter species (15%), Enterococcus species (12%) and Klebsiella pneumoniae (10%)were the common isolates. Most of the isolates were sensitive either to Nitrofurantoin, Norfloxacin or Amikacin. Conclusions: Asymptomatic bacteriuria is common in pregnancy. Urine culture sensitivity should be carried out routinely on all pregnant patients in order to prevent the dangerous complicationsassociated with it. Keywords: asymptomatic bacteriuria in pregnancy; urine culture and sensitivity.

Background: Asymptomatic bacteriuria is the presence of bacteria in the properly collected urine of a patient that has no signs and symptoms of urinary tract infection. Aim: This study was carried out to determine the incidence of asymptomatic bacteriuria in pregnant women in Saveetha medical college, Thandalam, Tamil Nadu. Materials and Methods: A total of 250 pregnant women attending antenatal clinic at civil hospital, Saveetha medical college, over a period of 3 months, with age groups between 18 to 30 years agreed to enter the study and were clinically evaluated. All these women were asked to submit clean catch midstream urine samples and it was examined under the microscope and by culture method. Results: A total of 250 pregnant women included in our study, with varying age groups between 18 to 30 years and the highest incidence was seen in between the 26 to 30 age group. Asymptomatic bacteriuria was seen in 27.2% of the pregnant women. The prevalence of Escherichia coli was among the most dominant organism, followed by Staphylococcus aureus ,klebsiella and proteus species. Conclusion: The study showed 27.2% of the pregnant women to have asymptomatic bacteriuria. This can be reduced by screening the mothers in first trimester and routine urine culture test must be carried out.

Abstract Introduction Diagnosis of urinary tract infection (UTI) in the elderly population is challenging as they commonly present with atypical signs and symptoms. Prevalence of asymptomatic bacteriuria in the elderly population is high. Hence, urine dipstick and urine culture are no longer diagnostic tests. UTI is over-diagnosed and overtreated in the elderly, resulting in poor antimicrobial stewardship. This project was carried out to assess and improve the current practices in the diagnosis and treatment of UTI in the Department of Medicine of the Elderly. Methods We reviewed current Scottish Intercollegiate Guidelines Network (SIGN) and National Institute for health and Care Excellence (NICE) guidelines on management of UTI and defined indications for performing urine dipstick and sending urine culture. We then collected and assessed data on all urine dipsticks performed, urine cultures sent, and use of antibiotics in treating UTI and asymptomatic bacteriuria in three Medicine of the Elderly wards in Aberdeen Royal Infirmary. We carried out intervention by means of presenting and discussing findings of Plan-Do-Study-Act (PDSA) cycles in departmental multi-disciplinary Quality Improvement (QI) meetings followed by educational sessions. Results Our baseline data showed 77% of urine dipsticks were performed without clinical indication and 18% of patients had urine cultures sent without clinical indication. After presenting our initial findings and carrying out an educational intervention session, 25% of patients had urine dipstick done without clinical indication, and 0% of patients had urine cultures sent without clinical indication. However, over the course of four subsequent PDSA cycles, practices in investigation of UTI fluctuated but were overall consistently better than the initial practice with further interventions. In all PDSA cycles, no patients were treated for asymptomatic bacteriuria. Conclusions Multidisciplinary team involvement in discussion of this QI project findings and educational sessions proved to be an effective form of intervention for improving current practice.

Abstract Background The Veterans’ Health Administration (VHA), currently mandates that every spinal cord injury and disorder (SCI/D) patient receives a screening urinalysis and urine culture (UC) during the annual evaluation (AE). Our pilot study at a single VHA center showed that 87% of the UCs obtained during the AE represented asymptomatic bacteriuria (ASB), and that 35% of those UC were treated with antibiotics unnecessarily. The objective of the current study is to determine the association between UC and antibiotic use using a national VHA sample of SCI/D patients. Methods Retrospective cohort of Veterans who presented to a VHA SCI/D clinic for their AE in FY18 or FY19. Demographic and clinical characteristics as well as information on primary outcomes (receipt of urine culture and antibiotics) were extracted from the VHA Corporate Data Warehouse. Associations between covariates and outcomes were assessed using logistic regression. P values < 0.05 were considered significant. Results 9447 veterans with SCI/D were included, of whom 5088 (54%) had a UC obtained. Of those with a UC, 2910 (57%) were classified as positive (Figure 1). 1054 (11%) veterans were prescribed antibiotics within 7 days of their AE. Of these, 515 had a positive UC, 202 had a negative UC, and 2878 did not have a UC obtained during the AE. Age, ethnicity, neurologic level of injury (NLI), comorbidity score, frequently identified organism on positive culture, and receipt of antibiotics within 7 days of AE were significantly associated with obtaining a UC during the AE. Race, NLI, bladder management strategy, comorbidity score, frequently identified organism on positive culture, and having a UC obtained during the AE were significantly associated with receipt of antibiotics within 7 days of AE. Flowchart of SCI/D Veterans who had a urine culture and/or received antibiotics during their FY18/19 AE Conclusion Over half of Veterans with SCI/D presenting for their AE receive a screening UC, contrary to other national guidelines recommending against this practice. Age and type or organism identified on UC drive antibiotic use, which was similar to our previous findings and reflect themes identified during our qualitative interviews with SCI/D providers. The knowledge gained from this national VA study will assist the development of interventions to reduce unnecessary urine testing and antibiotic use in the SCI/D population.

Swedish nursing homes are obliged to have a management system for systematic quality work including self-monitoring of which surveillance of infections is one part. The Department of Infection Control in Stockholm County Council has provided a simple system for infection surveillance to the nursing homes in Stockholm County since 2002. A form is filled in by registered nurses in the nursing homes at each episode of infection among the residents. A bacterial infection is defined by antibiotic prescribing and a viral infection by clinical signs and symptoms. Yearly reports of numbers of infections in each nursing home and calculated normalized figures for incidence, i.e. infections per 100 residents per year, as well as proportion of residents with urinary catheter are delivered to the medically responsible nurses in each municipality by the Department of Infection Control. Number of included residents has varied from 4,531 in 2005 to 8,157 in 2014 with a peak of 10,051 in 2009. The yearly incidences during 2005 - 2014 (cases per 100 residents) were: Urinary tract infection (UTI) 7.9-16.0, Pneumonia 3.7-5.3, Infection of chronic ulcer 3.4–6.8, Other infection in skin or soft tissue 1.4–2.9, Clostridium difficile-infection 0.2–0.7, Influenza 0–0.4 and Viral gastroenteritis 1.2–3.7. About 1 % of the residents have a suprapubic urinary catheter, 6–7 % have an indwelling urinary catheter. Knowledge about the incidence of UTI has contributed to the decrease of this infection both in residents with and without urinary catheter.

Background: With the emergence of antibiotic resistant threats and the need for appropriate antibiotic use, laboratory microbiology information is important to guide clinical decision making in nursing homes, where access to such data can be limited. Susceptibility data are necessary to inform antibiotic selection and to monitor changes in resistance patterns over time. To contribute to existing data that describe antibiotic resistance among nursing home residents, we summarized antibiotic susceptibility data from organisms commonly isolated from urine cultures collected as part of the CDC multistate, Emerging Infections Program (EIP) nursing home prevalence survey. Methods: In 2017, urine culture and antibiotic susceptibility data for selected organisms were retrospectively collected from nursing home residents’ medical records by trained EIP staff. Urine culture results reported as negative (no growth) or contaminated were excluded. Susceptibility results were recorded as susceptible, non-susceptible (resistant or intermediate), or not tested. The pooled mean percentage tested and percentage non-susceptible were calculated for selected antibiotic agents and classes using available data. Susceptibility data were analyzed for organisms with ≥20 isolates. The definition for multidrug-resistance (MDR) was based on the CDC and European Centre for Disease Prevention and Control’s interim standard definitions. Data were analyzed using SAS v 9.4 software. Results: Among 161 participating nursing homes and 15,276 residents, 300 residents (2.0%) had documentation of a urine culture at the time of the survey, and 229 (76.3%) were positive. Escherichia coli, Proteus mirabilis, Klebsiella spp, and Enterococcus spp represented 73.0% of all urine isolates (N = 278). There were 215 (77.3%) isolates with reported susceptibility data (Fig. 1). Of these, data were analyzed for 187 (87.0%) (Fig. 2). All isolates tested for carbapenems were susceptible. Fluoroquinolone non-susceptibility was most prevalent among E. coli (42.9%) and P. mirabilis (55.9%). Among Klebsiella spp, the highest percentages of non-susceptibility were observed for extended-spectrum cephalosporins and folate pathway inhibitors (25.0% each). Glycopeptide non-susceptibility was 10.0% for Enterococcus spp. The percentage of isolates classified as MDR ranged from 10.1% for E. coli to 14.7% for P. mirabilis. Conclusions: Substantial levels of non-susceptibility were observed for nursing home residents’ urine isolates, with 10% to 56% reported as non-susceptible to the antibiotics assessed. Non-susceptibility was highest for fluoroquinolones, an antibiotic class commonly used in nursing homes, and ≥ 10% of selected isolates were MDR. Our findings reinforce the importance of nursing homes using susceptibility data from laboratory service providers to guide antibiotic prescribing and to monitor levels of resistance.Disclosures: NoneFunding: None

Abstract Background Antibiotic use is commonly tracked electronically by antimicrobial stewardship programs (ASPs). Traditionally, evaluating the appropriateness of antibiotic use requires time- and labor-intensive manual review of each drug order. A drug-specific “appropriateness” algorithm applied electronically would improve the efficiency of ASPs. We thus created an antibiotic “never event” (NE) algorithm to evaluate vancomycin use, and sought to determine the performance characteristics of the electronic data capture strategy. Methods An antibiotic NE algorithm was developed to characterize vancomycin use (Figure) at a large academic institution (1/2016–8/2019). Patients were electronically classified according to the NE algorithm using data abstracted from their electronic health record. Type 1 NEs, defined as continued use of vancomycin after a vancomycin non-susceptible pathogen was identified, were the focus of this analysis. Type 1 NEs identified by automated data capture were reviewed manually for accuracy by either an infectious diseases (ID) physician or an ID pharmacist. The positive predictive value (PPV) of the electronic data capture was determined. Antibiotic Never Event (NE) Algorithm to Characterize Vancomycin Use Results A total of 38,774 unique cases of vancomycin use were available for screening. Of these, 0.6% (n=225) had a vancomycin non-susceptible pathogen identified, and 12.4% (28/225) were classified as a Type 1 NE by automated data capture. All 28 cases included vancomycin-resistant Enterococcus spp (VRE). Upon manual review, 11 cases were determined to be true positives resulting in a PPV of 39.3%. Reasons for the 17 false positives are given in Table 1. Asymptomatic bacteriuria (ASB) due to VRE in scenarios where vancomycin was being appropriately used to treat a concomitant vancomycin-susceptible infection was the most common reason for false positivity, accounting for 64.7% of false positive cases. After removing urine culture source (n=15) from the algorithm, PPV improved to 53.8%. Conclusion An automated vancomycin NE algorithm identified 28 Type 1 NEs with a PPV of 39%. ASB was the most common cause of false positivity and removing urine culture as a source from the algorithm improved PPV. Future directions include evaluating Type 2 NEs (Figure) and prospective, real-time application of the algorithm. Disclosures Marc H. Scheetz, PharmD, MSc, Merck and Co. (Grant/Research Support)

BACKGROUND Urinary tract infections (UTI) constitute a common cause of morbidity in infants and children. When associated with abnormalities of urinary tract, they may lead to long-term complications including renal scarring, loss of function and hypertension. Most urinary tract infections remain undiagnosed if investigations are not routinely performed to detect them. Prompt detection and treatment of urinary tract infections and any complicating factors are important. The objective of the study is to know the clinical, epidemiological and bacteriological profile (i.e. clinical signs and symptoms, age, sex, family history, associated urinary tract abnormalities, & causative organisms) of urinary tract infections in febrile children with culture positive urinary tract infection. METHODS This descriptive, cross sectional observational study was conducted at outpatient clinics of our “child health clinics” between May 2016 and April 2017 (one year). All children aged 0 to 12 years with culture positive urinary tract infections were included in this study to evaluate the clinical, epidemiological and bacteriological profile. RESULTS A total of 69 children with culture positive urinary tract infections were included in this study. Out of 69 children included in this study, 36 (52.2 %) were females and 33 (47.8 %) were males. Overall female preponderance was seen and the M: F ratio was 0.9:1. But during first year of life in our study group we had more boys (10, 14.49 %) affected with urinary tract infection than girls. 49.3 % of urinary tract infections in the present study belonged to lower socio-economic status. Most common organism causing urinary tract infection in our group was E. coli (56.5 %). Fever (100 %), anorexia or refusal of feeds (52.2 %), dysuria (46.4 %), vomiting (46.4 %) and abdominal pain (39.1 %) were the predominant clinical manifestations observed in our study. CONCLUSIONS Urinary tract infection is a common medical problem in children and it should be considered as a potential cause of fever in children. As febrile children with urinary tract infection usually present with non-specific signs and symptoms, urine culture should be considered as a part of diagnostic evaluation.
