Background Studies indicate that elderly patients are often inappropriately treated with antimicrobials for asymptomatic bacteriuria (ASB). Interprofessional education may help improve the assessment and management of ASB. Methods Retrospective chart audits were conducted on two cohorts of positive urine cultures (n = 201) obtained from a geriatric acute care unit to determine the incidence of treated ASB. The first cohort (n = 101) was analyzed from January to July 2017. Education was provided to unit staff (e.g., nurses, physicians, pharmacists) in Fall 2017. The second cohort (n = 100) was analyzed from January to July 2018. Descrip­tive statistics were used to summarize and compare the results from the cohorts. Results 152 patients (n = 201 positive urine cultures) were reviewed: 74% (159) of positive urine cultures were ASB and 21% (42) were urinary tract infections. The incidence of treated ASB was 15% (30) and untreated ASB was 65% (129). The incidence of UTI, treated ASB, and untreated ASB were not significantly different between the two cohorts examined. Conclusion The implementation of education did not result in lasting changes in ASB management. Our study suggests that future systemic solutions are necessary to reduce the incidence of treated ASB in the geriatric population.

Abstract Background One of the most readily available and cost effective tests in the diagnosis of urinary tract infections (UTI) is the urinalysis. Problems arise when antibiotic treatment is initiated in a patient who does not display typical signs and symptoms of UTI and for whom a urinalysis was obtained for other reasons. Methods This was a retrospective observational study carried out on 1000 patients with positive urine nitrite. Medical records were identified with subsequent analysis of urine culture and symptomatology. Recorded and analyzed data included: age, sex, location (emergency room (ER) or hospital ward), findings on urinalysis (pH, presence of leukocyte esterase(LE), epithelial cells, bacteria, and white blood cells (WBCs)) and antibiotic treatment. Results Of these 1000 patients with positive nitrite, we excluded 815 patients (81 had missing data, 466 met exclusion criteria and 268 had symptomatic UTI). 185 were found to not have any symptoms of a UTI. Inappropriate antibiotic treatment occurred in 108/185 patients (58.4%) and was significantly associated with greater amounts of bacteria and WBCs in the urinalyses (P = 0.008 and P = 0.029, respectively). It was also significantly more likely to occur in the ER than the hospital wards (92/147 treated in the ER vs. 16/37 treated on the hospital wards, P = 0.033). There was no significant association between antibiotic treatment and age, sex, urine pH, urine LE, and urine epithelial cell amounts (P > 0.05). Urine cultures were not obtained in 69.7% of patients. A positive urine culture was significantly associated with inappropriate antibiotic treatment (P = 0.0006). The two most common presenting complaints were psychiatric complaints (21.6%) and vaginal bleeding (14.6%). Conclusion Urinalysis can be an invaluable diagnostic tool, but must be used and interpreted appropriately. There is a misperception that pyuria with bacteriuria defines UTI. However, positive results on a urinalysis alone in an asymptomatic patient is not enough to diagnose a UTI, and antibiotic treatment is only indicated in specific circumstances as outlined by IDSA guidelines for the treatment of asymptomatic bacteriuria. Further education targeting appropriate interpretation of urinalyses and IDSA guidelines is needed to decrease the unnecessary use of antibiotics. Disclosures All authors: No reported disclosures.

Tract Infections

Urinary tract infections (UTIs) are associated with significant morbidity. We rely on clinical presentation, urinalysis, and urine culture to diagnose UTI. To differentiate between lower UTI and pyelonephritis, we depend on the clinical presentation. In the extremes of age and in immunocompromised individuals, clinical presentation is often atypical posing a challenge to diagnosis. In the elderly, the high prevalence of asymptomatic bacteriuria is another confounder. We conducted a search of publications to find novel biomarkers to diagnose UTI and to ascertain its severity. We searched PUBMED, MEDLINE and SCOPUS databases for studies pertaining to novel biomarkers and UTI. Two reviewers independently evaluated the methodology of the studies using the STARD (Standards for Reporting of Diagnostic Accuracy) criteria. We have identified procalcitonin as a biomarker to differentiate lower UTI from pyelonephritis in the pediatric age group. Elevated serum procalcitonin levels can result in early and aggressive treatment at the time of presentation. Interleukin 6 has also shown some promise in differentiating between lower UTI and pyelonephritis but needs further validation. Lastly, given the paucity of data in certain subgroups like diabetics, kidney transplant recipients, and individuals with spinal cord injury, further studies should be conducted in these populations to improve diagnostic criteria that will inform clinical management decisions.

In Reply.— Dr Roscelli calls attention to the 16 infants in our sample with positive urine cultures but negative urinalyses and admission diagnoses other than urinary tract infection (UTI). These patients, Dr Roscelli suggests, could have had asymptomatic bacteriuria with a different source for their fever. Although we doubt that these infants had asymptomatic bacteriuria, in theory it is possible that the bacteriuria was not the cause of the fever. However, as Dr Roscelli states, "at this time there no way to determine if the bacteriuria is causing the patient's fever or is simply an incidental finding."

This chapter on urinary tract infections brings up to date advice on the aetiology, diagnosis, and management of urinary tract infections in adults. The microbiology of this common presentation is discussed, together with recent patterns of resistance. Different clinical presentations are highlighted: lower UTI, upper UTI, asymptomatic bacteriuria, pregnancy, catheterized patients, haematuria, the elderly, urethral syndrome, interstitial cystitis and drug-induced cystitis. The role of different diagnostic tests, in particular routine urine culture, is explored. Guidance on the management of different clinical presentations of UTI is given, as well as an outline of the options for reducing the frequency of recurrent UTI in those so predisposed.

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 Urinary tract infections (UTI) caused by vancomycin-resistant enterococcus (VRE) are difficult to manage due to lack of effective oral treatment options. Linezolid is an antibiotic with activity against VRE that is available orally, but only 30% of each dose is excreted in the urine. Data on the efficacy of linezolid in the treatment of UTI is limited. The purpose of this analysis was to assess the comparative efficacy of linezolid to other VRE-active antibiotics in the treatment of UTI. Methods A national retrospective cohort of inpatient veterans with a positive urine culture for VRE during years 2013 through 2018 was developed. Patient demographics, vital signs, urinary symptoms, antibiotics prescribed, and 14-day post-treatment outcomes were collected. Patients without UTI symptoms, urine cultures with < 105 CFU/mL (<103 CFU/mL for catheterized patients), or patients not treated with VRE-active antibiotics were excluded. Odds ratios were used to compare linezolid and non-linezolid antibiotics for 14-day VRE bacteriuria, UTI retreatment, and death endpoints. Results Of 3,846 urine cultures identified with VRE, 624 (16%) patients were eligible for evaluation of UTI symptoms. Of these, 92/624 (15%) met study criteria. The primary reason for exclusion was asymptomatic bacteriuria [339/532 (64%)]. Linezolid was prescribed in 54/92 (59%) of cases. Comparators included penicillin’s [12/92 (13%)], nitrofurantoin [11/92 (12%)], daptomycin [7/92 (8%)], tetracycline’s [6/92 (7%)], and others [2/92 (2%)]. Between linezolid and comparator groups, mean (+S.D.) patient age [70 (12) vs. 68 (13) years, P = 0.45] and Charlson Comorbidity Index [8.9 (3.1) vs. 8.3 (3.5), P = 0.39] were similar. Negative outcomes were uncommon: 7% VRE bacteriuria, 8% UTI re-treatment, 4% death. No difference in [(OR) +95% CI] between linezolid and comparators was observed: positive VRE bacteriuria [0.3 (0.1, 1.9), P = 0.20], UTI retreatment [1.8 (0.3, 10.0), P = 0.49], death [1.4 (0.1, 16.1), P = 0.79]. Conclusion Most patients with a VRE positive urine culture who received antibiotics did not meet diagnostic criteria for UTI, and negative outcomes were uncommon. Linezolid and comparator regimens with VRE activity were effective for treating mild VRE UTI. Disclosures All authors: No reported disclosures.

Background.Obesity has reached epidemic proportions in dogs and, as in humans, cost of care has increased due to associated comorbidities. In humans, asymptomatic urinary tract infections (UTI) may be more prevalent in the obese. Asymptomatic bacteriuria (AB) is the term used when UTI are asymptomatic. We hypothesized that morbidly obese dogs are similarly more likely to have asymptomatic bacteriuria than lean, overweight, and moderately obese dogs.Methods.A retrospective study was undertaken to explore a possible association between obesity and asymptomatic bacteriuria. Records from lean, overweight, and obese dogs receiving both a dual energy absorptiometry (DXA) scan and urine culture were included.Results.Six positive urine cultures were identified among 46 dogs fulfilling search criteria. All six positive cultures were found in dogs with body fat percentage of >45%. In dogs with body fat percentage of <45%, there were no positive urine cultures.Discussion.There was an increased prevalence of asymptomatic bacteriuria in the morbidly obese dogs in this study compared to those that were lean, overweight, or moderately obese. Whether antibiotic therapy is necessary in such cases is still being debated, but because asymptomatic bacteriuria may be associated with ascending infections, uroliths, or other complications, the data reported herein support the screening of obese patients for bacteriuria.

BackgroundEscherichia coli bacteraemia rates are rising with highest rates in older adults. Mandatory surveillance identifies previous Urinary Tract Infections (UTI) and catheterisation as risk factors.AimTo help control bacteraemias in older frail patients by developing a patient leaflet around the prevention and self-care of UTIs informed by the Theoretical Domains Framework.MethodFocus groups or interviews were held with care home staff, residents and relatives, GP staff and an out of hours service, public panels and stakeholders. Questions explored diagnosis, management, prevention of UTIs and antibiotic use in older adults. The leaflet was modified iteratively. Discussions were transcribed and analysed using Nvivo.ResultsCarers of older adults reported their important role in identifying when older adults might have a UTI, as they usually flag symptoms to nurses or primary care providers. Information on UTIs needs to be presented so residents can follow; larger text and coloured sections were suggested. Carers were optimistic that the leaflet could impact on the way UTIs are managed. Older adults and relatives liked that it provided new information to them. Staff welcomed that diagnostic guidance for UTIs was being developed in parallel; promoting consistent messages. Participants welcomed and helped to word sections on describing asymptomatic bacteriuria simply, preventing UTIs, causes of confusion and when to contact a doctor or nurseConclusionA final UTI leaflet for older adults has been developed informed by the TDF.
