Abstract
BACKGROUND Catheter-associated urinary tract infections (CAUTIs) account for the majority of device-associated healthcare-acquired infections with significant morbidity and mortality worldwide. In developing countries with limited resources, the burden of CAUTI have substantial burden owing to the lack of well-organized infection prevention and control. Although there are studies in African countries, the magnitude of CAUTI is inconsistent. Therefore this systematic review and meta-analysis aimed to determine the pooled prevalence of CAUTI in Africa and identify the pathogens involved. METHODS Systematic review of articles from different databases and search engines such as Medline/PubMed, Google Scholar, Science Direct, and African Journal online were systematically searched to identify potential studies. Data were extracted on Microsoft Excel spreadsheet and analyzed using STATA 17.0. The pooled prevalence of CAUTI was estimated using a random effects model, inverse of variance was used to assess statistical heterogeneity across studies. Egger's tests was performed to identify possible publication bias. RESULTS This systematic review and meta-analysis incorporated twenty studies, revealing a pooled prevalence of CAUTI at 43.28%. Gram-negative bacteria were the leading cause of CAUTI accounts for 82.9%. Escherichia coli (45.06%) was the most frequent gram-negative bacterial isolate involved in CAUTI followed by Klebsiella spp (24.17%). Staphylococcus aureus was the predominant gram-positive bacterial isolate, accounting for 53.24% of gram-positive associated cases in CAUTI. CONCLUSION AND RECOMMENDATIONS In conclusion, the high prevalence of CAUTI in Africa underlines a pressing healthcare challenge. Addressing this issue requires a concerted effort, encompassing health education, infection prevention measures, resource allocation, and collaborative initiatives to enhance patient safety and mitigate the impact of CAUTI on healthcare systems in the region. As prolonged catheterization increases the risk of infection, catheters should only be used for proper indications and removed promptly when no longer needed.

Abstract
Introduction The emergence of multidrug-resistant Klebsiella pneumoniae (K. pneumoniae) and the decline of effective antibiotics lead to the urgent need for new antibacterial agents. The aim of this study is to investigate the therapeutic effect of antimicrobial peptides against gentamicin-resistant (RT) K. pneumoniae and to screen effective antimicrobial peptides. Methods In this study, the RT strains were induced by gradient gentamicin, and the RT strains were selected by detecting the expression levels of efflux pump genes, porin genes, and biofilm formation genes of the strains combined with their effects on the cells. Then the effects of four antimicrobial peptides on the efflux pump activity, biofilm formation level and cell condition after infection were detected to explore the effects of antimicrobial peptides on RT strains. Finally, the RT strain was used to induce a mouse model of pneumonia, and the four antimicrobial peptides were used to treat pneumonia mice for in vivo experiments. The pathological changes in lung tissues in each group were detected to explore the antimicrobial peptide with the most significant effect on the RT strain in vivo. Results The results showed that the minimal inhibitory concentrations of the RT strains (strain C and strain I) were significantly higher than those of the wild-type strain, and the expression of efflux pump, porin and biofilm formation genes was significantly increased. The antimicrobial peptides could effectively inhibit the biofilm formation and efflux pump protein function of the RT strains. In addition, the antimicrobial peptides showed promising antibacterial effects both in vitro and in vivo. Discussion Our study provided a theoretical basis for the treatment of gentamicin resistant K. pneumoniae infection with antimicrobial peptides, and found that KLA was significantly superior to LL37, Magainin I, KLA and Dermaseptin (10 μg/mL in cells, 50 μg in mice).

Abstract
INTRODUCTION Antimicrobial resistance (AMR) is currently a growing concern among healthcare providers, underscoring the importance of describing the regional susceptibility profile for common microorganisms that are associated with urinary tract infections (UTIs). This knowledge serves as the foundation for proper empirical therapeutic recommendations tailored to local susceptibility patterns. RESULTS We found a high prevalence of ESBL-producing strains (36.9%), with Escherichia coli and Klebsiella spp. being the most prevalent isolated bacteria. Among the catheterized patients, Klebsiella spp. emerged as the primary etiology, with a significant correlation between catheterization and Proteus spp. (p = 0.02) and Providencia stuartii (p < 0.0001). We observed significant correlations between urinary catheterization and older age (68.9 ± 13.7 years vs. 64.2 ± 18.1 years in non-catheterized patients, p = 0.026) and with the presence of an isolate with extensive drug resistance (p < 0.0001) or even pandrug resistance (p < 0.0001). Susceptibility rates significantly decreased for almost all the tested antibiotics during the study period. Notably, susceptibility was markedly lower among catheterized patients, with the most pronounced differences observed for carbapenems (59.6% versus 83.4%, p < 0.0001) and aminoglycosides (37.1% versus 46.9%, p = 0.0001). MATERIALS AND METHODS We conducted a retrospective study analyzing the susceptibility profiles of 724 extended-spectrum beta-lactamases (ESBL)-producing Enterobacterales isolated from urine cultures. Our focus was on highlighting susceptibility profiles among isolates associated with urinary catheterization and assessing the shifts in the susceptibility rates over time. CONCLUSIONS The constant rise in AMR rates among Enterobacterales presents significant challenges in treating severe infections, particularly among urinary catheterized patients. This trend leaves clinicians with limited or no effective treatment options. Consequently, the development and implementation of personalized treatment protocols are imperative to ensure efficient empirical therapies.

Abstract
Medical devices such as venous catheters (VCs) and urinary catheters (UCs) are widely used in the hospital setting. However, the implantation of these devices is often accompanied by complications. About 60 to 70% of nosocomial infections (NIs) are linked to biofilms. The main complication is the ability of microorganisms to adhere to surfaces and form biofilms which protect them and help them to persist in the host. Indeed, by crossing the skin barrier, the insertion of VC inevitably allows skin flora or accidental environmental contaminants to access the underlying tissues and cause fatal complications like bloodstream infections (BSIs). In fact, 80,000 central venous catheters-BSIs (CVC-BSIs)-mainly occur in intensive care units (ICUs) with a death rate of 12 to 25%. Similarly, catheter-associated urinary tract infections (CA-UTIs) are the most commonlyhospital-acquired infections (HAIs) worldwide.These infections represent up to 40% of NIs.In this review, we present a summary of biofilm formation steps. We provide an overview of two main and important infections in clinical settings linked to medical devices, namely the catheter-asociated bloodstream infections (CA-BSIs) and catheter-associated urinary tract infections (CA-UTIs), and highlight also the most multidrug resistant bacteria implicated in these infections. Furthermore, we draw attention toseveral useful prevention strategies, and advanced antimicrobial and antifouling approaches developed to reduce bacterial colonization on catheter surfaces and the incidence of the catheter-related infections.

Incidence of catheter-associated urinary tract infections by Gram-negative bacilli and their ESBL and carbapenemase production in specialized hospitals of Bahir Dar, northwest Ethiopia. Antimicrob Resist Infect Control 2024; 13:10. [PMID: 38273339 PMCID: PMC10809431 DOI: 10.1186/s13756-024-01368-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 01/12/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Catheter-associated urinary tract infections (CAUTIs) due to multidrug-resistant Gram-negative bacilli (GNB) is a common concern globally. Investigating the incidence of CAUTI and associated antibiotic resistance has paramount importance from the health care associated infections perspective. This study therefore assessed the incidence of CAUTIs due to GNB and the production of extended-spectrum beta-lactamase (ESBL) and carbapenemase among inpatients in specialized hospitals of Northwest, Ethiopia. METHODS A total of 363 patients with indwelling urinary catheters who were admitted in the hospital for > 48 h were consecutively enrolled and followed from 3 to 18 days. Data were collected through interviewing and review of medical records. Patients who developed at least one of the following: fever (> 38 OC), suprapubic tenderness, or costovertebral angle pain, coupled with a GNB positive urine culture of ≥ 103 CFU/mL with no more than two bacterial species were defined as CAUTI. The ESBL and carbapenemase production were detected and identified by chromogenic medium. Logistic regression analysis was done to identify associated factors. RESULTS From 363 patients followed, the incidence rate of CAUTI was 27.8 per 1000 catheter days. Catheterization for ≥ 8 days (AOR = 10.6, 95%CI:1.8-62.1) and hospitalization for > 10 days (AOR = 8.1, 95%CI: 2.4-27.2) were the factors significantly associated with CAUTIs. E. coli (n = 18, 34.6%), Proteus species (n = 7, 13.5%), and P. aeruginosa (n = 6, 11.5%) were the most frequent GNB. Isolates revealed high rates of resistance to amoxicillin-clavulanic acid (100%), cefazolin (n = 51, 98%), ceftazidime (n = 47, 90%) and cefotaxime (n = 46, 88%). Most of the GNB isolates (86.5%) were multidrug-resistant. Overall, 19.2% and 5.8% of GNB isolates were ESBL and carbapenemase producers, respectively. CONCLUSIONS Incidence of CAUTI with Gram-negative bacilli is high. As most of the GNB isolates are MDR and showed a super high rate of resistance to amoxicillin-clavulanic and third-generation cephalosporins, empirical treatment with these substances is virtually ineffective in patients with suspected GNB infection in Ethiopia. The expression of ESBL and carbapenemase among GNB isolates is also a concern. Therefore, improved infection prevention and control measures, careful use of catheters and third generation of cephalosporins are needed to improve patient outcomes and reduce the burden of CAUTIs and the spreading of antimicrobial resistance.

Novel Antibacterial Agents SAAP-148 and Halicin Combat Gram-Negative Bacteria Colonizing Catheters. Antibiotics (Basel) 2023; 12:1743.

Abstract
The antibiotic management of catheter-related infections (CRIs) often fails owing to the emergence of antimicrobial-resistant strains and/or biofilm/persister apparitions. Thus, we investigated the efficacy of two novel antimicrobial agents, i.e., the synthetic peptide SAAP-148 and the novel antibiotic halicin, against Gram-negative bacteria (GNB) colonizing catheters. The antibacterial, anti-biofilm, and anti-persister activities of both agents were evaluated against Acinetobacter baumannii, Escherichia coli, and Klebsiella pneumoniae strains. The enrolled strains were isolated from catheters and selected based on their resistance to at least three antibiotic classes and biofilm formation potential. Furthermore, the hemolysis and endotoxin neutralization abilities of these agents were explored. The bactericidal activity of both agents was reduced in urine and plasma as compared to buffered saline. In a dose-dependent manner, SAAP-148 and halicin reduced bacterial counts in 24 h preformed biofilms on silicone elastomer discs and eliminated persisters originating from antibiotic-exposed mature 7-day biofilms, with halicin being less effective than SAAP-148. Importantly, SAAP-148 and halicin acted synergistically on E. coli and K. pneumoniae biofilms but not on A. baumannii biofilms. The peptide, but not halicin, decreased the production of IL-12p40 upon exposure to UV-killed bacteria. This preliminary study showed that SAAP-148 and halicin alone/in combination are promising candidates to fight GNB colonizing catheters.

Abstract
OBJECTIVE Catheter-associated urinary tract infections (CAUTI) are common worldwide, but due to limited resources, its actual burden in low-income countries is unknown. Currently, there are gaps in knowledge about CAUTI due to lack of surveillance activities in Sierra Leone. In this prospective cohort study, we aimed to determine the incidence of CAUTI and associated antibiotic resistance in two tertiary hospitals in different regions of Sierra Leone. RESULTS The mean age of the 459 recruited patients was 48.8 years. The majority were females (236, 51.3%). Amongst the 196 (42.6%) catheterized patients, 29 (14.8%) developed CAUTI. Bacterial growth was reported in 32 (84%) patients. Escherichia coli (14, 23.7%), Klebsiella pneumoniae (10, 17.0%), and Klebsiella oxytoca (8, 13.6%) were the most common isolates. Most isolates were ESBL-producing Enterobacteriaceae (33, 56%) and WHO Priority 1 (Critical) pathogens (38, 71%). Resistance of K. pneumoniae, K. oxytoca, E. coli, and Proteus mirabilis was higher with the third-generation cephalosporins and penicillins but lower with carbapenems, piperacillin-tazobactam and amikacin. To reduce the high incidence of CAUTI and multi-drug resistance organisms, urgent action is needed to strengthen the microbiology diagnostic services and develop and implement catheter bundles that provide clear guidance for catheter insertion, care and removal.

Work experience was associated with the knowledge and practice of catheter-associated urinary tract infection prevention among nurses at University of Gondar Comprehensive Specialized Hospital, northwest Ethiopia, 2021. BMC Womens Health 2023; 23:40. [PMID: 36717910 PMCID: PMC9885554 DOI: 10.1186/s12905-023-02176-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 01/16/2023] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Catheter-associated urinary tract infection is the source of about 20% of episodes of health-care acquired infections in acute care facilities and it is over 50% in long-term care facilities. In Ethiopia, there is no published scientific research regarding knowledge and practice of nurses on catheter-associated urinary tract infections prevention. Therefore, this study aimed to assess knowledge, practice and associated factors of CAUTI prevention among nurses working at university of Gondar comprehensive specialized hospital, northwest Ethiopia, 2021. METHODS Institutional based cross sectional study was conducted at University of Gondar Comprehensive Specialized Referral Hospital from April 01 to May 01, 2021 among 423 nurses. Simple random sampling technique was used. Data were collected by using self-administered questionnaire then coded and entered into EPI- Data version 4.6 and then exported to SPSS version 23. Descriptive statistics was computed, and the result was summarized by texts, tables, and charts. All variables with P-value < 0.25 in the univariate analysis were included in the multivariable regression analysis. The degree of association was interpreted by using the adjusted odds ratio with 95% confidence intervals. RESULTS Good knowledge and practice of nurses towards CAUTI prevention was 37.7% and 51.8% respectively. Good knowledge was associated with sex [AOR = 1.84, 95% CI (1.09, 3.11)], work experience [AOR = 2.36, 95% CI (1.09, 5.10)], working unit [AOR = 6.9, 95% CI (2.11, 22.52)], training [AOR = 2.33, 95% CI (1.17, 4.65)] and had guideline [AOR = 2.78, 95% CI (1.59, 4.88)]. Good practice was associated with sex, work experience, attitude and knowledge towards CAUTI prevention [AOR = 2.19, 95% CI (1.23, 3.88)], [AOR = 5.44, 95% CI (1.66, 17.84)], [AOR = 3.06, 95% CI (1.65, 5.67)], and [AOR = 5.28, 95% CI (2.86, 9.76)] respectively. CONCLUSIONS Nearly one-third of nurses had good knowledge and more than half of nurses had good practice towards CAUTI prevention. Sex, work experience, work unit, presence of guideline, and training were significantly associated with knowledge. Sex, work experience, good attitude and, knowledge were associated with practice of nurses towards CAUTI prevention. The knowledge and practice towards catheter associated urinary tract infection prevention among nurses should be increased, so that the patients could enjoy and maintain the healthy lifestyle.

Abstract
Purpose of Review Nosocomial extracardiac infections after cardiac surgery are a major public health issue affecting 3–8.2% of patients within 30–60 days following the intervention. Recent Findings Here, we have considered the most important postoperative infective complications that, in order of frequency, are pneumonia, surgical site infection, urinary tract infection, and bloodstream infection. The overall picture that emerges shows that they cause a greater perioperative morbidity and mortality with a longer hospitalization time and excess costs. Preventive interventions and corrective measures, diminishing the burden of nosocomial extracardiac infections, may reduce the global costs. A multidisciplinary team may assure a more appropriate management of nosocomial extracardiac infections leading to a reduction of hospitalization time and mortality rate. Summary The main and most current data on epidemiology, prevention, microbiology, diagnosis, and management for each one of the most important postoperative infective complications are reported. The establishment of an antimicrobial stewardship in each hospital seems to be, at the moment, the more valid strategy to counteract the challenging problems.

Abstract
BACKGROUND Indwelling urinary catheters (IDCs) are a common invasive device in hospitalised patients. Their use is associated with increased risks of developing catheter associated urinary tract infections (CAUTI), and blood stream infections (BSI). AIMS To examine the characteristics and outcomes of adult inpatients with an IDC inserted in hospital and identify risk factors for developing CAUTI and BSI. METHODS We performed a retrospective observational study of 430 patients with IDC admitted to medical and surgical units of a leading (tertiary) hospital between Nov 2019 till April 2020. Multiple logistic regression analysis was performed to determine independent risk factors for developing urinary tract infection and blood stream infection. RESULTS The prevalence of CAUTI in our study was 7.4%. Results of multiple logistic regression indicated that with each day of IDC in situ, the likelihood of UTI development increased by 9% (OR 1.09; 95% CI 1.00 to 1.18; p = 0.03). Age, gender, and catheter reinsertion were not associated with UTI development. CONCLUSIONS Longer duration of IDC was associated with elevated risk of developing CAUTI. CAUTI rates were higher than some of those previously published. There was no statistical significance in frequency of CAUTI between medical and surgical patients. No statistically significant variables that contributed to the development of BSI were found. Interventions targeted at reducing catheter days should be used to improve CAUTI rates.

Loading of Polydimethylsiloxane with a Human ApoB-Derived Antimicrobial Peptide to Prevent Bacterial Infections. Int J Mol Sci 2022; 23:ijms23095219. [PMID: 35563610 PMCID: PMC9103716 DOI: 10.3390/ijms23095219] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 04/28/2022] [Accepted: 05/04/2022] [Indexed: 01/02/2023] Open
Abstract
Background: medical device-induced infections affect millions of lives worldwide and innovative preventive strategies are urgently required. Antimicrobial peptides (AMPs) appear as ideal candidates to efficiently functionalize medical devices surfaces and prevent bacterial infections. In this scenario, here, we produced antimicrobial polydimethylsiloxane (PDMS) by loading this polymer with an antimicrobial peptide identified in human apolipoprotein B, r(P)ApoBLPro. Methods: once obtained loaded PDMS, its structure, anti-infective properties, ability to release the peptide, stability, and biocompatibility were evaluated by FTIR spectroscopy, water contact angle measurements, broth microdilution method, time-killing kinetic assays, quartz crystal microbalance analyses, MTT assays, and scanning electron microscopy analyses. Results: PDMS was loaded with r(P)ApoBLPro peptide which was found to be present not only in the bulk matrix of the polymer but also on its surface. ApoB-derived peptide was found to retain its antimicrobial properties once loaded into PDMS and the antimicrobial material was found to be stable upon storage at 4 °C for a prolonged time interval. A gradual and significant release (70% of the total amount) of the peptide from PDMS was also demonstrated upon 400 min incubation and the antimicrobial material was found to be endowed with anti-adhesive properties and with the ability to prevent biofilm attachment. Furthermore, PDMS loaded with r(P)ApoBLPro peptide was found not to affect the viability of eukaryotic cells. Conclusions: an easy procedure to functionalize PDMS with r(P)ApoBLPro peptide has been here developed and the obtained functionalized material has been found to be stable, antimicrobial, and biocompatible.

Antimicrobial Resistance and Predisposing Factors Associated with Catheter-Associated UTI Caused by Uropathogens Exhibiting Multidrug-Resistant Patterns: A 3-Year Retrospective Study at a Tertiary Hospital in Mogadishu, Somalia. Trop Med Infect Dis 2022; 7:tropicalmed7030042. [PMID: 35324589 PMCID: PMC8948891 DOI: 10.3390/tropicalmed7030042] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 02/25/2022] [Accepted: 02/28/2022] [Indexed: 11/23/2022] Open
Abstract
Background: Widespread and rapidly emerging multidrug-resistant uropathogens, particularly carbapenem-resistant pathogens, are a public health concern that impairs the determination of empirical therapy. This study aims to evaluate the antimicrobial susceptibility profile and factors associated with catheter-associated urinary tract infection (CA-UTI). Method: This retrospective study was carried out on a total of 779 urine cultures over a 3-year period. Antimicrobial sensitivity tests were performed using the standard Kirby−Bauer disk diffusion method. Results: The prevalence of CA-UTI in our study was 12.7%; a total of 47% of cultures had multi-drug-resistant (MDR) uropathogens, and 13% of the cultures showed extended-spectrum beta-lactamase (ESBL)-producing pathogens. Elderly patients, intensive care unit admissions, and associated comorbidities were correlated with higher rates of CA-UTI caused by multidrug-resistant uropathogens (p < 0.021, 95% CI: 0.893−2.010), (p < 0.008, 95% CI: 1.124−5.600), (p < 0.006, 95% CI: 0.953−2.617). Latex catheters and prolonged catheterization time were associated with increased risk of CA-UTI (p < 0.0001, 95% CI: 0.743−1.929, p = 0.012, 95% CI: 0.644−4.195). Patients with MDR uropathogens had prolonged hospital stays, i.e., 49% in more than 2 weeks (p < 0.04, 95% CI: 0.117−3.084). E. coli was the most common pathogen (26.3%), followed by Acinetobacter baumannii (24.3%). Acinetobacter baumannii showed the highest MDR pattern (88.5%), followed by Pseudomonas aeruginosa (68%). Acinetobacter baumannii and Klebsiella pneumoniae were associated with prolonged hospital stays (>2 w at 73.1 and 69%, respectively). Higher antimicrobial resistance against ceftriaxone (85.7%), meropenem (54.3%), ertapenem (50%), ciprofloxacin (58.5%), amikacin (27%), tigecycline (7.6%), and colistin (4.6%), was revealed in the study. Conclusion: Aside from the higher antimicrobial resistance against cephalosporins and fluoroquinolones, the findings of this study revealed that carbapenems are facing increased rates of antimicrobial resistance and are associated with substantial morbidity, prolonged hospitalization times, and increased healthcare expenses.

Abstract
Background Urinary catheter (UC)–associated infections are one of the most common
preventable healthcare-associated infections (HAIs) and they frequently
occur in older, frail populations. Aim The study aim was to describe the incidence of UC-associated infection in
elderly patients undergoing hip fracture surgery after implementing a
preventive care bundle. Methods A longitudinal prospective study using a before-and-after design. The bundle
was theory driven and involved the co-creation of a standard operational
procedure, education and practical training sessions. Prospectively
collected registry data were analysed. Univariable statistics and
multivariable logistic regressions were used for analyses. Results 2,408 patients with an acute hip fracture were included into the study. There
was an overall reduction in UC catheter associated-associated urinary tract
infections, from 18.5% (n = 75/406) over time to 4.2%
(n = 27/647). When adjusting for all identified
confounders, patients in phase 4 were 74% less likely to contract an
UC-associated infection (OR, 0.26; 95% CI, 0.15–0.45, p
< 0.0001). Discussion Bundled interventions can reduce UC-associated infections substantially, even
in elderly frail patients. Partnership and co-creation as implementation
strategies appear to be promising in the fight against HAI.

Abstract
Urinary tract infections (UTIs) are common healthcare-associated infections (HAIs) in older adults that live in long-term care (LTC) facilities. A query of the Pennsylvania Patient Safety Reporting System (PA-PSRS) found that symptomatic UTI (SUTI) and catheter-associated UTI (CAUTI) rates increased from 2016 and peaked in the second quarter of 2020. Although the number of urinary catheter days reported by LTC facilities has trended downward from 2016 to the beginning of 2020, the urinary catheter utilization rate increased slightly in the second quarter of 2020. We also examined various epidemiological factors. An average of 47.6% of SUTIs and 32.3% of CAUTIs were associated with E. coli from 2016 through 2020. However, the percentage of CAUTIs associated with E. coli decreased while the percentage of CAUTIs associated with organisms of the tribe Proteeae (Proteus, Providencia, and Morganella genera) increased from 2016 through 2020. Furthermore, the percentage of CAUTIs associated with carbapenem-resistant Enterobacterales (CRE) and organisms producing extended-spectrum beta-lactamases (ESBL) also increased, while the percentage of CAUTIs associated with vancomycin-resistant Enterococci (VRE) decreased from 2016 through 2020. An average of 38.5% of SUTIs and 41.5% of CAUTIs were reported to be treated with fluoroquinolones from 2016 through 2020. However, the percentage of both SUTIs and CAUTIs treated with fluoroquinolones decreased from 2016 through 2020, while an increasing percentage of both SUTIs and CAUTIs was reported to have been treated with cephalosporins and carbapenems from 2016 through 2020. Thus, to further promote resident safety, we use these epidemiological trends to better understand current risks for residents and to further guide development of best practices for prevention, identification, and treatment of UTIs as well as to further advance antibiotic stewardship practices.

Abstract
Introduction Catheter-associated urinary tract infections (CAUTIs) are the most common nosocomial infection and a leading cause of morbidity. The aim of this study was to determine the prevalence, associated factors and antibiogram of the bacterial isolates among CAUTIs patients. Methods A facility-based, cross-sectional study was conducted from March to December 2019 at Arba Minch General Hospital, Southern Ethiopia. Clinical and socio-demographic data were obtained using a questionnaire. Clean catch midstream urine samples were collected and inoculated onto blood agar, MacConkey agar, and cysteine lactose electrolyte deficient agar (CLED). The inoculated culture media were incubated in an aerobic atmosphere at 37°C for 24 h. After overnight incubation, the bacterial growth on the respective media was inspected visually and graded for the presence of significant bacteriuria. A significant bacteriuria was considered, if pure culture at a concentration of ≥105 colony forming unit (CFU)/mL. All isolates were further identified using colony morphology and biochemical tests. Antimicrobial sensitivity was determined by modified Kirby–Bauer disc diffusion method. Data were analyzed using SPSS version 25. P-value less than 0.05 was used as statistical significance. Results The overall incidence of symptomatic CAUTIs was 39/231 (16.8%). Independent predictors of CAUTIs were prolonged (≥7 days) catheterization (AOR = 3.6, 95% CI = 1.0–12.2), diabetes mellitus (AOR = 5.3, 95% CI = 1.4–19.6) and insertion of catheter in surgical ward (AOR = 3.6, 95% CI = 1.08–12.28). The most common bacterial isolates were E. coli 17/42 (40.5%), Klebsiella species 9/42 (21.4%) and Enterococcus species 5/42 (11.9%). High (>80%) drug resistance was observed against cotrimoxazole, cefoxitin and tetracycline. Ciprofloxacin and nitrofurantoin were the most active drugs. The overall prevalence of MDR among isolates was 37/42 (88.1%). Most bacterial isolates 30/42 (71.4%) were biofilm producers. Conclusion High levels of drug resistance were observed to commonly used antibiotics. In our study, biofilm-producing bacterial isolates were the predominant cause of CAUTIs. Therefore, continuous surveillance of antimicrobial resistance patterns is necessary to help physicians in treatment and management of CAUTIs.

Abstract
This thematic review was part of a bigger literature review into the effects of short-term urinary catheters on patients who are discharged home from an acute hospital. This integrated review examined the risks associated with short-term urinary catheters. The MEDLINE, British Nursing Index and CINAHL databases were searched for studies published between 2013 and 2018 that researched the effects of short-term urinary catheters on patients. Twelve research studies were included, which showed the presence of short-term indwelling urinary catheters increased the risk of infection, length of hospital stay and mortality rates. Short-term urinary catheters should be strictly monitored and removed as soon as they are not required.

Abstract
Background The study aimed to investigate the changes in nosocomial infection density after patients were transferred to the intensive care unit (ICU) of a new-build hospital. Methods The types and rates of nosocomial infections were obtained for a one-year period retrospectively before leaving the old hospital premises and for a one-year periods after moving into the new hospital. The intensive care unit in the “old” premises was comprised of a 17-bedded hall, and thirty-three nurses shifted to work forty-eight hours a week, with each nurse assigned to provide care for two patients. The intensive care unit in the “new” premises consisted of single rooms, each with twenty-eight beds. Results The median nosocomial infection density decreased from 23 to 15 per 1000 in-patient days. The catheter-related urinary tract infection rate decreased from 7.5 to 2.6 per100 catheter days. Conclusions Treatment of patients in the new hospital resulted in a decrease in nosocomial infection density.

Abstract
PURPOSE Catheter-associated urinary tract infection (CAUTI) is a priority quality metric for hospitals. The impact of placement of indwelling urinary catheter (IUC) by medical students on CAUTI rates is not well known. This study examined the impact of a simulation-based medical student education curriculum on CAUTI rates at an academic medical center. METHOD Patient characteristics, procedural data, and outcome data from all operating room IUC insertions from June 2011 through December 2016 at the Northwestern University Feinberg School of Medicine were analyzed using a multivariable model to evaluate associations between CAUTI and inserting provider. Infection data before and after implementation of a simulation-based IUC competency course for medical students were compared. RESULTS A total of 57,328 IUC insertions were recorded during the study period. Medical students inserted 12.6% (7,239) of IUCs. Medical students had the lowest overall rate of CAUTI among all providers during the study period (medical students: 0.05%, resident/fellows: 0.2%, attending physicians: 0.3%, advanced practice clinicians: 0.1%, nurses: 0.2%; P = .003). Further, medical student IUC placement was not associated with increased odds of CAUTI in multivariable analysis (odds ratio, 0.411; 95% confidence interval: 0.122, 1.382; P = .15). Implementation of a simulation-based curriculum for IUC insertion resulted in complete elimination of CAUTI in patients catheterized by medical students (0 in 3,471). CONCLUSIONS IUC insertion can be safely performed by medical students in the operating room. Simulation-based skills curricula for medical students can be effectively implemented and achieve clinically relevant improvements in patient outcomes.

Abstract
Background Although catheter-associated urinary tract infection (CA-UTI) is a major healthcare-related problem worldwide, there is a scarcity of current data from countries with high antimicrobial resistance rates. We aimed to determine the clinical outcomes of patients with CA-UTI compared to those of patients with other sources of complicated urinary tract infection (cUTI), and to assess the impact of antimicrobial resistance. We also aimed to identify the factors influencing 30-day mortality among patients with CA-UTI. Methods This was a multicentre, multinational retrospective cohort study including hospitalised adults with cUTI between January 2013 and December 2014 in twenty hospitals from eight countries from southern Europe, Turkey and Israel. The primary endpoint was 30-day mortality. The secondary endpoints were length of hospital stay, symptom improvement after 7 days' treatment, symptom recurrence at 30 days and readmission 60 days after hospital discharge. Results Of the 807 cUTI episodes, 341 (42.2%) were CA-UTIs. The time from catheter insertion to cUTI diagnosis was less than 2 weeks in 44.6% of cases. Overall, 74.5% of cases had hospital or healthcare-acquired CA-UTI. Compared to patients with other cUTI aetiologies, those with CA-UTI had the following characteristics: they were more frequently males, older, admitted for a reason other than cUTI and admitted from a long-term care facility; had higher Charlson's comorbidity index; and more frequently had polymicrobial infections and multidrug-resistant Gram-negative bacteria (MDR-GNB). Patients with CA-UTI also had significantly higher 30-day mortality rates (15.2% vs 6%) and longer hospital stay (median 14 [interquartile range -IQR- 7-27] days vs 8 [IQR 5-14] days) than patients with cUTI of other sources. After adjusting for confounders, CA-UTI was not independently associated with an increased risk of mortality (odds ratio, 1.40; 95% confidence interval, 0.77-2.54), and neither was the presence of MDR-GNB. Conclusions CA-UTI was the most frequent source of cUTI, affecting mainly frail patients. The mortality of patients with CA-UTI was high, though this was not directly related to the infection.

Abstract
AIMS AND OBJECTIVES To identify the point prevalence of indwelling urinary catheters (IDCs) in adult inpatients in acute care hospitals, and to describe the indications for IDC insertion based on patient age, gender, specialty and hospital. BACKGROUND Catheter-associated urinary tract infections (CAUTIs) are preventable healthcare-associated infections. IDC duration is the strongest predictor of CAUTI, and little is known about characteristics of patients who receive an IDC. DESIGN Two single-day point prevalence surveys collected baseline patient data as part of a larger pre-post control-intervention study. METHODS Surveys were conducted at four acute care hospitals in NSW, Australia, for all adult patients. Data collection included IDC presence, insertion details and urine culture collection. Point prevalence data were linked with electronically extracted patient demographic data. This study is presented in line with STROBE checklist (See Supplementary File 1). RESULT Data from 1,630 patients were analysed, with 196 patients (12%) identified as having an IDC on the survey dates. IDC prevalence rates were higher in males (13%) than in females (11%). Critical care had the highest rate of patients with IDCs (42%). Urine cultures were collected in 70 patients with an IDC (43%). CONCLUSIONS Findings indicated similar rates of IDC use in males and females, and there was no significant difference in age between patients with or without an IDC. However, indication for IDC varied by patient age and gender. High rates of urine culture collection may represent routine collection. RELEVANCE TO CLINICAL PRACTICE IDC use is found across genders, all age groups and specialties. Nurses should be aware that any of their patients may have an IDC and be particularly aware of certain indications based on patient age and gender. Routine urine culture collection is not advised, and instead, nurses should be guided by clinical decision-making tools.

Abstract
AIM To evaluate the performance of the new device compared with clean intermittent catheterization (CIC). METHODS From March 2015 to March 2018, patients who were admitted to the urologic outpatient clinic. A new intraurethral self-retaining device (ISRD) was made of medical grade silicone and it was inspired by similar catheters that use sliding disks to adjust or fix tubes used to drain the bladder. Patients were randomized into two groups (experimental group [GI]-ISRD vs control group [GII]-CIC). The evaluation was performed at the time of enrollment and 6 months after treatment. Intervention was initiated from the antisepsis of the perineal region and subsequent introduction of the device through the external urethral meatus. The primary outcome was quality of life (QOL). Urinary tract infections (UTIs) episodes, data on urodynamic parameters, adverse effects and number of diapers per day. RESULTS A total of 177 subjects were analyzed. We found a significant improvement on QOL analysis in the ISRD group (P < .01). ISRD group presented an important reduction (two episodes after ISRD use) on number of UTIs (P < .01) and diaper use, and significant improvement on bladder capacity (80 mL of the average improvement) (P < .01) and compliance (P = .01). Among all registered serious adverse effects, ISRD presented with lower proportion. CONCLUSIONS The new device has shown to be a safe and promising alternative for adequate emptying of the neurogenic bladder in female patients. Our study has a limitation that is related to a limited period of observation.

Abstract
AIMS The study aimed to identify the risk factors for catheter-associated urinary tract infection among hospitalized patients. We also tried to explore its potential effect on patient outcomes if possible. BACKGROUND Catheter-associated urinary tract infection accounts for a large proportion of healthcare-associated infections and remains a considerable threat to patient safety worldwide. DESIGN A systematic review and meta-analysis of observational studies. DATA SOURCES We conducted an electronic search in PubMed, EMBASE, Web of Science, and the Cochrane Database of Systematic Reviews for studies published between January 2008-January 2018. REVIEW METHODS Two reviewers searched the articles and extracted the data independently. The quality of the studies was assessed with the Newcastle-Ottawa Scale. RevMan 5.3 was used to perform the meta-analysis. RESULTS Ten studies involving a total of 8785 participants with or without catheter-associated urinary tract infection were included. The average incidence of catheter-associated urinary tract infection was 13.79 per 1000 catheter days, with a prevalence rate of 9.33%. The meta-analysis demonstrated that patients at high risk for catheter-associated urinary tract infection were female, had a prolonged duration of catheterization, had diabetes, had previous catheterization, and had longer hospital and ICU stays. Additionally, catheter-associated urinary tract infection was also accompanied by an increase in mortality. CONCLUSIONS Healthcare staff should focus on the identified risk factors for catheter-associated urinary tract infection. Further research is needed to investigate the microbial isolates and focus on the intervention strategies of catheter-associated urinary tract infection, so as to reduce its incidence and related mortality.

Abstract
Resumo Objetivo: Avaliar a influência do tempo de exposição e calibre na formação de biofilme em cateteres urinários de Foley (CUFs). Método: Pesquisa in vitro com amostras de fragmentos de CUFs em látex siliconizado de diferentes calibres (n° 14 e n° 16 Frenchs). A urina artificial foi confeccionada, inoculada com bactérias-padrão Staphylococcus aureus (ATCC 25923) e Pseudomonas aeruginosa (ATCC 27853) e incubada a 37 °C por 24 horas e 72 horas. As análises foram realizadas por meio de cultura (carga bacteriana) e microscopia eletrônica de varredura. Resultados: Não houve diferença na carga bacteriana dos biofilmes formados nas superfícies dos CUFs com relação aos diferentes calibres (p > 0,05). Por outro lado, o tempo de exposição (24 horas e 72 horas) foi o fator determinante para formação do biofilme de P. aeruginosa nos CUFs (p < 0,05). Conclusão: O tempo de exposição influenciou a formação do biofilme de P. aeruginosa nos CUFs, independentemente dos calibres.

Abstract
Background Catheter-associated urinary tract infection (CAUTI) is a common nosocomial infection. However, the effectiveness of antimicrobial catheters in reducing CAUTI in cerebral infarction patients is unknown. The purpose of this study was to determine whether antimicrobial catheters protect against CAUTI in cerebral infarction patients. Methods We identified 27,548 patients from the Japanese Diagnosis Procedure Combination Database who had been admitted from April 1, 2012 through March 31, 2014 for acute management of cerebral infarction and had used at least an indwelling urethral catheter. We extracted data on patient sex, age, comorbidity, length of stay, activities of daily living (ADL), surgery, hospital case volume, and catheter type. We defined CAUTI as a urinary tract infection arising during admission. We performed multi-level logistic regression analysis to analyze the reduction in CAUTI using antimicrobial catheters. Results The rate of CAUTI was 8.8% and 8.3% in the control and antimicrobial catheter groups, respectively. Significant risk factors for CAUTI were age, diabetes requiring insulin therapy, low ADL score, and long hospitalization. Incidence rate was significantly lower in operated cases and those treated with tissue plasminogen activator. For all cases overall, the use of an antimicrobial catheter was not associated with a lower CAUTI rate. However, use was associated with a lower rate of CAUTI in diabetic patients on insulin. Conclusions Antimicrobial catheter use was not associated with a lower incidence rate of CAUTI in acute cerebral infarction patients. However, stratified analysis suggested that use was associated with a lower incidence in diabetic patients on insulin.

Abstract
Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogen that can adhere to host cells or extracellular matrix via type 1 and type 3 fimbriae. KP1_4563 is a gene encoding a hypothetical protein in K. pneumoniae NTUH-K2044. KP1_4563 is located between the type 1 and type 3 fimbrial gene clusters and is likely associated with fimbrial function given its putative conserved domains of unknown function (DUF1471). Cyclic AMP receptor protein (CRP) regulates virulence-related gene expression and is a crucial transcriptional regulator in many bacteria. The predicted DNA recognition motif of CRP is present in the KP1_4563 promoter region. This study aimed to investigate the function of KP1_4563 in fimbriae and its transcriptional regulation mechanism by CRP. We generated Kp-Δ4563 mutant and complementation strains. We utilized phenotype and adhesion assays to evaluate the role of KP1_4563 in fimbriae. We conducted quantitative RT-PCR (qRT-PCR), LacZ fusion, electrophoretic mobility shift, and DNase I footprinting assays to study the transcriptional regulation of KP1_4563 gene by CRP. We found that KP1_4563 negatively regulates the function of type 3 fimbriae. Compared with NTUH-K2044, the absence of KP1_4563 enhanced the ability of Kp-Δ4563 to adhere to A549 cells. CRP negatively regulates KP1_4563 by directly binding to its promoter region. KP1_4563 plays an important role in type 3 fimbrial function. This novel insight will assist in the development of strategies for preventing K. pneumoniae infection.

Abstract
BACKGROUND Urinary tract infection (UTI) is the most frequent nosocomial infection in geriatric units. An understanding of risk factors for infection may help to identify prevention strategies. AIM Identification of the risk factors for UTI in elderly patients. METHODS Retrospective analysis of three prospective cohorts. All hospitalized patients present in, or admitted to, a geriatric unit from June 1st to June 28th, for the years 2009, 2012, and 2015 were included and followed until discharge or until June 30th of the year concerned. For each patient, type and dates of stay, type and dates of catheter, risk factors, and nosocomial UTI (NUTI) data were collected. Univariate and multivariate (Cox model) analyses were made using SPSS software. FINDINGS A total of 4669 patients were included and were followed for a total of 83,068 days. There were 189 NUTIs (4.0% patients). NUTIs were significantly more frequent among female patients, in rehabilitation units, in immunosuppressed patients, among those with acute retention, post-void residual, history of urinary tract infection in the previous six months, and in case of dependency. NUTIs were significantly more frequent among those who had a catheter (Z-test, P < 0.001). NUTIs were more frequent among patients with intermittent, indwelling, or suprapubic catheters. They were also more frequent in acute/subacute care or rehabilitation units, in women, in immunosuppressed patients, and in those with a history of previous UTI; they were less frequent in dementia patients. CONCLUSION The occurrence of NUTI is an important issue in both catheterized and non-catheterized patients; prevention programmes should be widened to include non-catheterized patients.

[PMID: 28185802 DOI: 10.1016/j.burns.2016.07.008] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2016] [Revised: 06/29/2016] [Accepted: 07/14/2016] [Indexed: 12/16/2022]
Abstract
INTRODUCTION Worldwide, burns are responsible for more than 300,000 deaths annually; infection is a major cause of morbidity and mortality in these patients. Early identification and treatment of infection improves outcome. Toward this end it's necessary to identify the institutions flora and organisms that most frequently produces infection. OBJECTIVES To characterize infections developed by burn patients hospitalized at the University Hospital of Santander (HUS). METHODOLOGY Burn patients hospitalized in the HUS from January 1 to December 2014 were followed. Medical information regarding infections, laboratory and pathology reports were obtained. Statistical analysis with measures of central tendency, proportions, global and specific incidence density plus overall and specific incidence was obtained. For the microbiological profile proportions were established. RESULTS 402 burn patients were included, 234 (58.2%) men and 168 (41.8%) women, aged between 6 days and 83 years, median 12.5 years. The burn agents include scald (52.5%), fire (10.0%), gasoline (9.2%), electricity (7.5%), among others. Burn area ranged from 1% to 80% TBS. Cumulative mortality was 1.5%. 27.8% of burned patients had one or more infections. Identified infections include folliculitis (27.0%), urinary tract infection (19.0%), infection of the burn wound (10.4%), pneumonia (8.6%), Central venous catheter (7.4%), bloodstream infection (7.4%) and skin grafts infection (4.3%) among others. Bacteria were responsible for 88.5% of the cases and fungi 11.5%. The most frequently isolated germs were P. aeruginosa, A. baumannii, E. coli, S. aureus and K. pneumoniae. Most gram-negative bacteria were sensitive to Amikacin, gram positive bacteria were sensitive to multiple antibiotics. CONCLUSION Burns is a severe trauma that occurs in adult and pediatric patients, has several causative agents and can compromise the patient's life. The burned patient is at risk for a variety of infections. According to the type of infection it is possible to infer the most common causative organisms and their antibiotic sensitivity/resistance which allow a directed early empiric treatment.
