AbstractWe compared interventions to improve urinary catheter care and urine culturing in adult intensive care units of 2 teaching hospitals. Compared to hospital A, hospital B had lower catheter utilization, more compliance with appropriate indications and maintenance, but higher urine culture use and more positive urine cultures per 1,000 patient days.

Abstract Objective: Urine cultures have poor specificity for catheter-associated urinary tract infections (CAUTIs). We evaluated the effect of a urine-culture stewardship program on urine culture utilization and CAUTI in adult intensive care units (ICUs). Design: A quasi-interventional study was performed from 2015 to 2017. Setting and patients: The study cohort comprised 21,367 patients admitted to the ICU at a teaching hospital. Intervention: The urine culture stewardship program included monthly 1-hour discussions with ICU house staff emphasizing avoidance of “pan-culture” for sepsis workup and obtaining urine culture only if a urinary source of sepsis is suspected. The urine culture utilization rate metric (UCUR; ie, no. urine cultueres/catheter days ×100) was utilized to measure the effect. Monthly UCUR, catheter utilization ratio (CUR), and CAUTI rate were reported on an interactive quality dashboard. To ensure safety, catheterized ICU patients (2015–2016) were evaluated for 30-day readmission for UTI. Time-series data and relationships were analyzed using Spearman correlation coefficients and regression analysis. Results: Urine culture utilization decreased from 3,081 in 2015 to 2,158 in 2016 to 1,218 in 2017. CAUTIs decreased from 78 in 2015 to 60 in 2016 and 28 in 2017. Regression analysis over time showed significant decreases in UCUR (r, 0.917; P < .0001) and CAUTI rate (r, 0.657; P < .0001). The co-correlation between UCUR and CAUTI rate was (r, 0.625; P < .0001) compared to CUR and CAUTI rate (r, 0.523; P = .004). None of these patients was readmitted with a CAUTI. Conclusions: Urine culture stewardship program was effective and safe in reducing UC overutilization and was correlated with a decrease in CAUTIs. Addition of urine-culture stewardship to standard best practices could reduce CAUTI in ICUs.

Background and Purpose: The formation of a bacterial biofilm on an indwelling urinary catheter is considered to be a leading cause for diagnosed urinary tract infections in the intensive care setting (Djeribi, Bouchloukh, Jouenne, & Menaa, 2012). Bacterial biofilms (colonization) are thought to develop between one to five days (Saint & Chenoweth, 2003). Neuroscience patients are of particular interest when examining biofilm formation, as their underlying disease processes pose unique challenges to decreasing indwelling catheter device days, including neurogenic bladder, need for euvolemic fluid volume states, et cetera. The purpose of this quality improvement initiative was targeted at reducing the number of diagnosed false-positive CAUTI. Methods: For a period of February 2014- July 2014, nurses in two neurosciences intensive care units at a large academic center piloted an intervention targeted at reducing the number of diagnosed false-positive CAUTI, thought to occur as a result of catheter colonization or biofilm formation. For the intervention, patients who received an order for a urine culture who had an indwelling catheter for equal to or greater than five days had their indwelling catheter changed. Urine cultures were subsequently obtained from the new indwelling catheter. Results: Data for the months ( February 2014-July 2014) included a total of 87 patients from the neurosciences intensive care units who met the criteria for an indwelling catheter change, in the event that they had a urine culture ordered on or after device day five. Twenty six patients had their indwelling catheter changed prior to urine specimens being obtained. Five of the twenty six obtained from the new indwelling catheters demonstrated growth at the time the reports were finalized. Compared to previous CAUTI rates for the same time period in 2013 we have reduced the absolute numbers from 30 to 13. Conclusions: The organization’s infection control board reviewed the data and permission was granted to extend the pilot to all adult ICU. The preliminary data does suggest bacterial biofilm may contribute to the rate of CAUTI in the neuroscience population.

Objectives: To investigate clinical characteristics, bacterial characteristics, drug resistance status in patients with urinary tract infections treated at Department of Urology, Hue University Hospital. Materials and Method: The study was conducted in 474 patients with urological disease treated at Department of Urology, Hue Universiry Hospital from July 2017 to April 2018. Urine culture was done in the patients with urine > 25 Leu/ul who have symptoms of urinary tract disease or infection symptoms. Patients with positive urine cultures were analyzed for clinical and bacterial characteristics. Results: 187/474 (39.5%) patients had symptoms associated with urinary tract infections. 85/474 (17.9%) patients were diagnosed with urinary tract infection. The positive urine culture rate was 45.5%. Symptoms of UTI were varied, and no prominent symptoms. E. coli accounts for the highest proportion (46.67%), followed by, Staphycoccus aureus (10.67%), Pseudomonas aeruginsa (8,0%), Streptococcus faecali and Proteus (2.67%). ESBL - producing E. coli was 69.23%, ESBL producing Enterobacter spp was 33.33%. Gram-negative bacteria are susceptible to meropenem, imipenem, amikacin while gram positive are vancomycin-sensitive. Conclusions: Clinical manifestations of urinary tract infections varied and its typical symptoms are unclear. E.coli is a common bacterium (46.67%). Isolated bacteria have a high rate of resistance to some common antibiotics especially the third generation cephalosporins and quinolones. Most bacteria are resistant to multiple antibiotics at the same time. Gram (+) bacteria are susceptible to vancomycin, and gram (-) bacteria are susceptible to cefoxitin, amikacin, and carbapenem. Key words: urinary tract infection

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.

Background: Urinary tract infections (UTIs) are one of the most frequently reported infections in older adults and the most common reason for antimicrobial prescribing in nursing homes (NHs). In this vulnerable population, both a good diagnosis and prevention of these infections are crucial as overuse of antibiotics can lead to a variety of negative consequences including the development of multidrug-resistant organisms. Objective: To determine infection prevention and control (IPC) and diagnostic practices for UTIs in Belgian NHs. Methods: Local staff members had to complete an institution-level questionnaire exploring the availability of IPC practices and resources and procedures for UTI surveillance, diagnosis, and urinary catheter and incontinence care. Results: UTIs were the second most common infections in the 87 participating NHs (prevalence: 1.0%). Dipstick tests and urine cultures were routinely performed in 30.2% and 44.6% of the facilities, respectively. In non-catheterised residents, voided or midstream urine sampling was most frequently applied. Protocols/guidelines for urine sampling, urinary catheter care and incontinence care were available in 43.7%, 45.9% and 31.0% of the NHs, respectively. Indwelling catheters were uncommon (2.3% of the residents) and urinary retention (84.9%) and wound management (48.8%) were the most commonly reported indications. Only surveillance was found to significantly impact the UTI prevalence: 2.2% versus 0.8% in NHs with or without surveillance, respectively ( P < 0.001). Discussion: This survey identified key areas for improving the diagnosis and prevention of UTIs, such as education and training regarding the basics of urine collection and catheter care.

Urinary tract infections (UTIs) are the most common bacterial pathologies in children, but they are difficult to spot. The diagnosis relies on urine culture in order to measure the prevalence of the infection, to identify the etiology and the sensitivity of the germs to different antibiotics. Escherichia coli (E. coli) strains are the most common uro-pathogen germs. The change in sensitivity to antibiotic of these uro-pathogen bacteria should be closely monitored because the physicians should be informed about the evolution of the antibiotic resistance of E coli, for a more effective treatment in their fight against diseases. The study aimed to determine the prevalence of UTIs and the evolution of antimicrobial sensitivity for E. coli. This retrospective study was performed over a period of 4 years, 2013-2016, and included all the patients admitted in the Children�s Hospital, aged 0-18 years, with the suspicion of UTIs; also, the standard culture techniques for urine samples, the modified Kirby-Bauer disk diffusion method for the antibiotic sensitivity testing, and the disk diffusion method to confirm the ESBL production by the clinical isolates of E. coli in urine were used. The statistical analysis was performed using the proportions of sensitive, resistant and intermediates. Descriptive statistics like the total, mean and percentage were performed using the Statistical Package for the Social Sciences (SPSS), version 15.0 and Microsoft Excel. From 15389 urine cultures processed in 4 years, 1530 were positive (9.9 %). Among these positive urine cultures, 1056 (69 %) were positive for E. coli. Testing the E. coli to a range of antibiotics, according to CLSI standard, a high resistance to Ampicillin (69-96%), Amoxicillin/Clavulanic acid (32-70%), Trimethoprim/Sulfamethoxazole (36-42%) was observed and low levels of resistance to Ceftazidime, Cefuroxime, Cefpodoxime, Gentamycin, Nalidixic acid. Among E. Coli strains, 9-9.6 % were ESBL positive. Despite the low number of positive urine cultures in a paediatric population, it is very important to perform the urine culture in order to correctly identify the etiology of UTIs, recommend the right antibiotic, and avoid the wrong use of the antibiotics in children.

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 &gt; 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.
