Project description:Background: Urinary tract infection (UTI) represents one of the most common infectious diseases and a major cause of antibiotic prescription in children. To prevent recurrent infections and long-term complications, low-dose continuous antibiotic prophylaxis (CAP) has been used. However, the efficacy of CAP is controversial. The aim of this document was to develop updated guidelines on the efficacy and safety of CAP to prevent pediatric UTIs. Methods: A panel of experts on pediatric infectious diseases, pediatric nephrology, pediatric urology, and primary care was asked clinical questions concerning the role of CAP in preventing UTIs in children. Overall, 15 clinical questions were addressed, and the search strategy included accessing electronic databases and a manual search of gray literature published in the last 25 years. After data extraction and narrative synthesis of results, recommendations were developed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Results: The use of CAP is not recommended in children with a previous UTI, with recurrent UTIs, with vesicoureteral reflux (VUR) of any grade, with isolated hydronephrosis, and with neurogenic bladder. CAP is suggested in children with significant obstructive uropathies until surgical correction. Close surveillance based on early diagnosis of UTI episodes and prompt antibiotic therapy is proposed for conditions in which CAP is not recommended. Conclusions: Our systematic review shows that CAP plays a limited role in preventing recurrences of UTI in children and has no effect on its complications. On the other hand, the emergence of new antimicrobial resistances is a proven risk.

Project description:Gram-negative uropathogenic Escherichia coli (UPEC) bacteria are a causative pathogen of urinary tract infections (UTIs). Previously developed antivirulence inhibitors of the type 1 pilus adhesin, FimH, demonstrated oral activity in animal models of UTI but were found to have limited compound exposure due to the metabolic instability of the O-glycosidic bond (O-mannosides). Herein, we disclose that compounds having the O-glycosidic bond replaced with carbon linkages had improved stability and inhibitory activity against FimH. We report on the design, synthesis, and in vivo evaluation of this promising new class of carbon-linked C-mannosides that show improved pharmacokinetic (PK) properties relative to O-mannosides. Interestingly, we found that FimH binding is stereospecifically modulated by hydroxyl substitution on the methylene linker, where the R-hydroxy isomer has a 60-fold increase in potency. This new class of C-mannoside antagonists have significantly increased compound exposure and, as a result, enhanced efficacy in mouse models of acute and chronic UTI.

Project description:Background:In 2011, The Infectious Diseases Society of America released a clinical practice guideline (CPG) that recommended short-course antibiotic therapy and avoidance of fluoroquinolones for uncomplicated urinary tract infections (UTIs). Recommendations from this CPG were rapidly disseminated to clinicians via review articles, UpToDate, and the Centers for Disease Control and Prevention website; however, it is unclear if this CPG had an impact on national antibiotic prescribing practices. Methods:We performed a retrospective cohort study of outpatient and emergency department visits within a commercial insurance database between January 1, 2009, and December 31, 2013. We included nonpregnant women aged 18-44 years who had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for a UTI with a concurrent antibiotic prescription. We performed interrupted time series analyses to determine the impact of the CPG on the appropriateness of the antibiotic agent and duration. Results:We identified 654 432 women diagnosed with UTI. The patient population was young (mean age, 31 years) and had few comorbidities. Fluoroquinolones, nonfirstline agents, were the most commonly prescribed antibiotic class both before and after release of the guidelines (45% vs 42%). Wide variation was observed in the duration of treatment, with >75% of prescriptions written for nonrecommended treatment durations. The CPG had minimal impact on antibiotic prescribing behavior by providers. Conclusions:Inappropriate antibiotic prescribing is common for the treatment of UTIs. The CPG was not associated with a clinically meaningful change in national antibiotic prescribing practices for UTIs. Further interventions are necessary to improve outpatient antibiotic prescribing for UTIs.

Project description:BackgroundPediatric catheter-associated urinary tract infection (CAUTI) prevention guidelines encourage family engagement; however, there is a dearth of research on parent-facing CAUTI prevention resources. We aimed to meet the learning needs of parents about CAUTI prevention in the hospital by developing and refining an educational pamphlet with parents.MethodsPhase 1: We compiled existing evidence from CAUTI prevention guidelines and conducted a focus group with parents to form learning objectives. Phase 2: We developed prototype design elements, tested initial designs with a survey, and conducted qualitative participatory design sessions with parents to iteratively refine the pamphlet until design saturation was reached.ResultsWe identified the following key themes and preferences: (1) Clear boundaries for engagement (e.g., parents would not be emptying the catheter); (2) Positive, actionable framing (e.g., what should proper catheter positioning look like?); (3) What to expect (e.g., is the catheter painful for my child?); (4) Parents considered both their and their child's comprehension of the content when providing feedback.ConclusionsOverall, we demonstrated the utility of remote participatory design methods in developing and refining a CAUTI prevention resource based on parents' preferences. Future research should consider adapting these methods and implementing formal evaluation for comprehension for eventual integration into clinical practice.

Project description:BackgroundUrinary tract infections (UTIs) are common in pregnancy and account for the highest proportion of primary care antibiotic prescriptions issued to pregnant women in the UK. It is well known that antibiotic use is associated with increased antimicrobial resistance and therefore measures to minimise antibiotic use for UTI prevention have been studied. The efficacy and safety of these measures in pregnancy have not been addressed and therefore the aim of this study was to systematically review the literature to identify and evaluate potential measures to prevent UTIs in pregnant women.MethodsTen databases (EMBASE, AMED, BNI, CINAHL, Medline, PubMed, PsycINFO, Cochrane Trials, Scopus and Science Direct) were systematically searched in July 2017 for studies reporting non-antibiotic measures to prevent UTIs in pregnancy. The terms ("urinary tract infection" or UTI or bacteriuria or cystitis) AND (prevention) AND (pregnan*) were used. The quality of the publications was appraised using the Critical Appraisal Skills Programme (CASP) checklists for cohort study, case-control study and randomised controlled trial. The results were synthesised using a textual narrative approach.ResultsSearch results yielded 3276 publications and after reviewing titles and removing duplicates, 57 full text articles were assessed for eligibility and eight were included in the review. Five different approaches (hygiene measures, cranberry juice, immunisation, ascorbic acid and Canephron® N) have been identified, all of which are reported to be safe in pregnancy.ConclusionThe quality of the evidence varied considerably and only hygiene measures were supported by evidence to be recommended in practice. Future work needs to concentrate on strengthening the evidence base through improved design and reporting of studies with a focus on immunisation, ascorbic acid and Canephron® N.

Project description:ObjectiveAntibiotics are the most common class of medication prescribed in pediatrics, with the majority of prescriptions occurring in the outpatient setting. Our objective was to evaluate the accuracy of antibiotic dose, frequency, and formulation prescribed for urinary tract infections (UTIs) in the pediatric ambulatory care setting.MethodsThis was a retrospective review of electronic medical records conducted at 2 suburban pediatric practices in a mid-sized metropolitan region. Encounter-related prescriptions were identified using UTI-associated International Classification of Diseases, 10th Revision codes. Patients aged 2 months through 18 years were included if they had been prescribed an oral antibiotic for the treatment of UTI. Antibiotic dose, frequency, and formulation were considered accurate if consistent with clinical guidelines and tertiary dosing references.ResultsNearly 1 in 4 prescriptions had dosing inaccuracies. The proportion of errors was highest with amoxicillin-clavulanate (75%; 9/12) and amoxicillin (52%; 33/64). The most common reasons for dosing incorrectly were "low dose" or "unnecessarily high dose." Additionally, 55% of the included prescriptions were for oral suspensions, and 1 in 4 of these were dosed incorrectly.ConclusionsInaccuracies in antibiotic prescribing for pediatric UTI are common, including for frequently prescribed agents and oral formulations. To address these missed opportunities for stewardship in the outpatient setting, key educational sessions with providers should include reviewing optimal antibiotic dosing for uropathogens and highlighting common errors when oral suspensions are prescribed.

Project description:Current organizational guidelines regarding use of antibiotics during urinary tract catheterization are based on limited evidence and are not directly applicable to the pediatric urology population. We seek to improve understanding of this population by first evaluating current practices. This study aims to investigate practice patterns and attitudes of pediatric urologists regarding the use of antibiotics in the setting of urinary tract catheterization.An online survey was sent to members of the Society for Pediatric Urology. Questionnaire sections included demographics, general questions about antibiotic use with catheterization, and specific clinical scenarios. Descriptive statistics were used, and chi-square analysis was performed to examine associations between demographics and specific responses.Of 448 pediatric urologists surveyed, 154 (34%) responded to the survey. A majority of surveyed urologists (78%) prescribe daily prophylactic antibiotics with a hypospadias stent in place, but extensive variation in use of antibiotics was reported with other catheters and tubes. Extensive variation in practice patterns was also reported for three case scenarios regarding antibiotic prophylaxis with catheterization. Urologists >?50 years of age and fellowship-trained urologists were more likely to prescribe antibiotics for hypospadias stents (p = 0.02, p = 0.03), but no other significant associations between demographic characteristics and antibiotic use were found.There is substantial variation in practice patterns among surveyed pediatric urologists regarding prophylactic antibiotic use with urinary catheterization. This variation, combined with a lack of objective data and increasing pressure to decrease infectious complications and combat antibiotic resistance, highlights the need for development of management guidelines for this unique population.

Project description:INTRODUCTION:Urinary tract infections (UTI) are a common indication for antibiotic use in the emergency department (ED). With antibiotic resistance on the rise, it is essential that antibiotics be prescribed appropriately for UTIs. Our objective was to evaluate the appropriateness of antibiotic prescriptions by ED providers for uncomplicated cystitis and pyelonephritis. METHODS:We conducted a retrospective study of females ages 2-50 years seen in an academic ED from January 2017 to April 2018 diagnosed with UTI. We assessed the appropriateness of discharge antibiotic prescriptions, as determined by adherence to clinical practice guidelines, best evidence for the particular indication (cystitis vs pyelonephritis for children and adults), and the local antibiogram. RESULTS:A total of 421 patients were included in this study. Of these, 60 children and 198 adults were diagnosed with cystitis, and 47 children and 116 adults were diagnosed with pyelonephritis. Treatment in the absence of true infection was common, with culture-confirmed UTI occurring in only 17/50 (34%) of children and 60/129 (47%) of adults diagnosed with cystitis, and 23/40 (58%) of children and 58/87 (67%) of adults diagnosed with pyelonephritis, among patients who had urine cultures. The type of antibiotic prescribed was appropriate in 53/60 (88%) of children and 135/198 (68%) of adults with cystitis, and 38/47 (81%) of children and 53/116 (46%) of adults with pyelonephritis. The most common inappropriate antibiotic types were beta-lactams in adults (n = 92), nitrofurantoin for pyelonephritis (n = 16), and amoxicillin (n = 15). Dosing and duration errors were also common, occurring in 122/279 (44%) of prescriptions of an appropriate antibiotic type. The frequency of errors in the type of antibiotic prescribed was similar among provider types (attending physician, resident physician, and advanced practice clinician; p = 0.926). CONCLUSION:This study reveals room for improvement in antibiotic prescription practices across provider cohorts in the ED for the management of uncomplicated cystitis and pyelonephritis in females.

Project description:Complications of urinary tract infections (UTIs) like kidney failure and septicaemia develop once infections spread from the upper urinary tract to other parts of the body by haematogenous dissemination and they pose great health and economic burden to the countries. This retrospective study was conducted among 132 patients with bacterial UTIs in the inpatient department of tertiary care hospital in Abha, Saudi Arabia. During the study period, Escherichia coli (E. coli) and Klebsiella pneumonia (K. pneumonia) along with other 15 different bacteria were isolated. A significant difference (P < 0.05) was observed between the male and female children population in different age groups. We observed fever (84.09%) as a major symptom (P < 0.05), and seizure (9%) was reported as a major concomitant condition among UTI cases. Around 31.82% of E. coli was found to be the most common uropathogens in pediatric cases followed by 25% in K. pneumoniae. E. coli was observed to be more susceptible (92.86%) to amikacin, ceftriaxone, levofloxacin, ertapenem, gentamycin, meropenem, piperacillin-tazobactam, tigecycline, and ceftazidime. However, meropenem, tigecycline, and amikacin were observed to be effective in 100% of cases of K. pneumoniae. Meanwhile, cephalosporins were the most commonly prescribed drug category among different classes of drugs. Almost 99% of pediatric cases, based on their age, were admitted to the ward, and drugs were administered intravenously. We concluded that microbiology laboratory evidence on the causative organisms and choice of treatment together allows tailoring appropriate treatment regimens in conjunction with clinical experiences.

Project description:OBJECTIVE To characterize the diagnosis and management of urinary tract infection (UTI) in pediatric patients at the University of Illinois Hospital and Health Sciences System (UIH), with an emphasis on antibiotic prescribing; in addition, to characterize pediatric uropathogen patterns to help guide future empiric therapy choices. METHODS We used a retrospective, descriptive study of pediatric patients ages 2 months to ≤18 years seen at the UIH emergency department or clinic from January 1, 2014, to August 31, 2018, with ICD-9 or ICD-10 discharge diagnosis of UTI. Data collected included presenting symptoms, urinalysis, details of antibiotic regimens, urine culture, and susceptibility results. RESULTS Of the 207 patients included, the median age was 5.7 years (IQR, 3.2–9.4), and 183 patients (88.4%) were female. Common symptoms included dysuria (57%) and fever (37%). Empiric antibiotics were p-rescribed in 96.1% of cases, most commonly cefdinir (42%), cephalexin (22%), and sulfamethoxazole-trimethoprim (14%). Urine cultures were collected in 161 patients (77.8%), with 81 growing >50,000 colony-forming units bacteria. Escherichia coli was the most commonly isolated organism (82.1%), showing susceptibility to third-generation cephalosporins (97%), nitrofurantoin (95%), and sulfamethoxazole-trimethoprim (84%). Although 25 urine cultures showed no growth, antibiotics were discontinued in only 4 cases. CONCLUSIONS Pediatric patients with UTI symptoms were often empirically prescribed cefdinir, possibly an unnecessarily broad choice because many E coli isolates were susceptible to narrower agents. Both urinalysis and urine cultures should be obtained during the diagnostic evaluation of UTI, with better follow-up of negative cultures to potentially discontinue antibiotics. This study highlights areas for improvement in the diagnosis, treatment, and antimicrobial stewardship in pediatric UTI.
