[Inappropriate treatment of asymptomatic bacteriuria]. / 5 minutes pour apprendre. Traitement problématique d'une bactériurie asymptomatique.

Asymptomatic bacteriuria is frequently encountered in clinical practice and should be treated only in pregnant women and before invasive urological procedures. Inappropriate treatment of asymptomatic bacteriuria is associated with numerous adverse effects including allergic reactions, increased antibiotics resistance and increase risk of Clostridioides difficile infection. Positive urinary culture often leads to antimicrobial treatment, irrespective of urinary symptoms. Therefore, urine analysis and culture should be performed only in symptomatic individuals or in asymptomatic individuals with a clear indication for treatment.

Bacteriological profile, antimicrobial susceptibility, and factors associated with urinary tract infection in pregnant women.

INTRODUCTION: Urinary tract infection (UTI) is a common bacterial complication in pregnancy. The study aimed to estimate the prevalence, risk factors, and bacterial etiology of UTI during pregnancy and determine the efficacy of antimicrobial drugs in treating UTIs. METHODOLOGY: Urine specimens and clinical data were collected from pregnant women who attended primary health centers in Erbil, Iraq. All specimens were cultured on appropriate media and identified by standard microbiological methods. The pregnant women were grouped into symptomatic UTI group, asymptomatic bacteriuria group, and the control group. The agar dilution method was used to determine antimicrobial susceptibility. RESULTS: Among the 5,042 pregnant women included in this study, significant bacteriuria was found in 625 (12.40%) of the cases, and 198 (31.68%) had symptomatic UTI, of which 43.59% were diagnosed during the third trimester. Out of the 643 bacteria isolated, 33.28% were symptomatic UTI, of which 43.59% developed during the third trimester. There was a significant difference in the bacterial etiology between symptomatic UTI and asymptomatic bacteriuria (p = 0.002), as well as between cystitis and pyelonephritis (p = 0.017). The most common bacterial species isolated was Escherichia coli, which was susceptible to fosfomycin (100%), meropenem (99.45%), and nitrofurantoin (97.8%). CONCLUSIONS: Pregnant women are more likely to develop UTI in the third trimester. Escherichia coli is the predominant pathogen. The study suggests the use of fosfomycin, meropenem, and nitrofurantoin for the treatment of UTI. No Gram-positive isolates were resistant to daptomycin.

Reducing Treatment of Asymptomatic Bacteriuria: What Works?

Asymptomatic bacteriuria is common, but usually benign. Inappropriate antimicrobial treatment of asymptomatic bacteriuria contributes to negative antimicrobial outcomes. Optimizing antimicrobial use for bacteriuria is a component of antimicrobial stewardship programs and includes key practices of dissemination and implementation of guidelines, laboratory practices which support stewardship, and programs to monitor and implement optimal antimicrobial treatment for urinary infection. These activities vary in their effectiveness, costs, and complexity to institute. Stewardship strategies targeting unique populations with a high prevalence of bacteriuria and for whom symptom assessment is not straightforward need to be further developed and evaluated to support optimal stewardship.

Diagnostic Stewardship for Urine Cultures.

Urinary tract infections are among the most common infectious diagnoses in health care, but most urinary tract infections are diagnosed inappropriately in patients without signs or symptoms of infection. Asymptomatic bacteriuria leads to inappropriate antibiotic prescribing and negative downstream effects, including antimicrobial resistance, health care-associated infections, and adverse drug events. Diagnostic stewardship is the process of modifying the ordering, performing, or reporting of test results to improve clinical care. Diagnostic stewardship impacts the diagnostic pathway to decrease inappropriate detection and treatment of asymptomatic bacteriuria. This article reviews diagnostic stewardship methods and closes with a case study illustrating these principles in practice.

Asymptomatic bacteriuria in patients with type 2 diabetes mellitus in rural southwestern Nigeria: a cross-sectional study.

OBJECTIVES: We aimed to identify the prevalence, bacterial isolates, antimicrobial susceptibility profile, and factors associated with asymptomatic bacteriuria (ASB) in patients with type 2 diabetes mellitus (T2DM) in rural southwestern Nigeria. METHODS: We performed a hospital-based cross-sectional study of patients with T2DM and ASB. Demographic and clinical data were collected using questionnaires. Urine samples were cultured using standard laboratory procedures, and bacterial colonies were isolated and antimicrobial sensitivity was performed using the disc diffusion technique. Relationships between variables were assessed using adjusted odds ratios (AORs) and 95% confidence intervals (CIs). RESULTS: Of the 280 participants, 73 (26.1%) had ASB (95% CI: 20.9%-31.2%). The most commonly identified isolate was E. coli (45/73; 61.7%), 100.0% of which were sensitive to cefuroxime but resistant to ciprofloxacin. Female sex (AOR, 6.132; 95% CI: 2.327-16.157), living below the poverty line (AOR, 2.066; 95% CI: 1.059-4.029), uncontrolled blood glucose (AOR, 2.097; 95% CI: 1.000-4.404), and a history of indwelling urethral catheterization (AOR, 14.521; 95% CI: 4.914-42.908) were associated with ASB. CONCLUSION: The findings suggest that cefuroxime should be used as an empirical treatment, pending urine culture and sensitivity, and that efforts should be made to prevent ASB in rural southwestern Nigeria.

Bacteriuria in patients with stented ureters: predictors of infection in patients presenting to the hospital and when not to treat.

PURPOSE: Patients with ureteric stents have symptoms that overlap with infection symptoms. Thus, clinicians unnecessarily give antibiotics to stented patients with bacteriuria despite guidelines. In stented patients, little is known about risk factors for developing bacteriuria or urosepsis. The objectives were to identify the frequency and risk factors for developing bacteriuria and urosepsis in patients with stents. METHODS: In this retrospective cohort study, we reviewed patients with ureteric stents placed or exchanged over 1 year. We examined associations between bacteriuria or urosepsis and host risk factors. Univariable and multivariable logistic analyses were performed. RESULTS: Of 286 patients (mean age: 57.2 years), 167 (58.4%) were male. The main stent indications were stone, stricture, cancer and extrinsic compression. The median stented period was 61 days. The frequency of bacteriuria was 59/286 (21%). ASA status 3 and 4 had 5 times the odds of having bacteriuria relative to ASA status 1. Stent duration > 2 months had 5.5 times the odds relative to ≤ 2 months. Urosepsis was infrequent, 13/286 (4.5%). Five patients had bacteraemia. A stent duration over 2 months had nearly 6 times the odds of urosepsis. CONCLUSION: ASA status higher than 2 and stent time greater than 2 months raise the odds of developing bacteriuria. A stent duration longer than 2 months was the only predictor of urosepsis. Though 21% of patients had bacteriuria, 4.5% had urosepsis. Hence, bacteriuria without sepsis should not be treated with antibiotics, thus aiding antimicrobial stewardship.

Decision-making and Treatment Preferences Surrounding Bacteriuria in Nonpregnant Women: A Qualitative Investigation.

INTRODUCTION AND HYPOTHESIS: Best practices suggest nontreatment for asymptomatic bacteriuria in a nonpregnant population, yet there is little literature on patient preference or understanding of asymptomatic bacteriuria treatment. We hypothesize that there might be core factors that affect antibiotic preferences and care-seeking decisions for urinary tract infection and asymptomatic bacteriuria in a postmenopausal population. METHODS: We performed semi-structured interviews with postmenopausal individuals who had been previously treated for at least one patient-reported urinary tract infection. Interviews covered a discussion about their approach to seeking antibiotics for management and knowledge/preferences for asymptomatic bacteriuria management. Two authors independently coded the interviews and identified a set of symptom-related knowledge and experiences that relate to care-seeking and treatment preferences. We then graphically represented a mental model of antibiotic-seeking practices as an influence diagram, illustrating how knowledge and values affect preferences for care. RESULTS: We performed 30 interviews of participants with a mean age of 69.4 (SD 6.4). Among participants, there were four core factors that influence antibiotic seeking for bacteriuria. Participants noted concern for sequelae from untreated bacteria as their primary motivation, but also noted past experiences, information sources, and testing results as themes that affected their mental model surrounding bacteriuria treatment. CONCLUSIONS: The cognitive approach to care-seeking and treatment preference for bacteriuria is influenced by a few central factors. An improved ability to allay concerns either by provider discussions or educational materials are necessary to bridge the gap from the existence of evidence-based guidelines to patient and provider comfort with adherence to these guidelines.

Proposing the "Continuum of UTI" for a Nuanced Approach to Diagnosis and Management of Urinary Tract Infections.

PURPOSE: Patients with suspected UTIs are categorized into 3 clinical phenotypes based on current guidelines: no UTI, asymptomatic bacteriuria (ASB), or UTI. However, all patients may not fit neatly into these groups. Our objective was to characterize clinical presentations of patients who receive urine tests using the "continuum of UTI" approach. MATERIALS AND METHODS: This was a retrospective cohort study of a random sample of adult noncatheterized inpatient and emergency department encounters with paired urinalysis and urine cultures from 5 hospitals in 3 states between January 01, 2017, and December 31, 2019. Trained abstractors collected clinical (eg, symptom) and demographic data. A focus group discussion with multidisciplinary experts was conducted to define the continuum of UTI, a 5-level classification scheme that includes 2 new categories: lower urinary tract symptoms/other urologic symptoms and bacteriuria of unclear significance. The newly defined continuum of UTI categories were compared to the current UTI classification scheme. RESULTS: Of 220,531 encounters, 3392 randomly selected encounters were reviewed. Based on the current classification scheme, 32.1% (n = 704) had ASB and 53% (n = 1614) did not have a UTI. When applying the continuum of UTI categories, 68% of patients (n = 478) with ASB were reclassified as bacteriuria of unclear significance and 29% of patients (n = 467) with "no UTI" were reclassified to lower urinary tract symptoms/other urologic symptoms. CONCLUSIONS: Our data suggest the need to reframe our conceptual model of UTI vs ASB to reflect the full spectrum of clinical presentations, acknowledge the diagnostic uncertainty faced by frontline clinicians, and promote a nuanced approach to diagnosis and management of UTIs.

Impact of altered mental status on antibiotic prescribing and outcomes in hospitalized patients presenting with pyuria.

BACKGROUND: Pyuria is nonspecific and may result in over-treatment of asymptomatic bacteriuria (ASB). The Infectious Diseases Society of America recommends against antibiotic treatment of ASB for most patients including those presenting with altered mental status (AMS). Close observation is recommended over treatment to avoid missing alternative causes of AMS and overuse of antibiotics resulting in adverse events and resistance. OBJECTIVES: The purpose of this study was to evaluate patient outcomes associated with antibiotic treatment of pyuria in patients presenting with AMS at hospital admission without specific urinary tract infection (UTI) symptoms. The primary objective was to compare 30-day readmission rates of patients with pyuria and AMS treated with antibiotics (AMS+Tx) versus those who were not treated (AMS-NoTx). Secondary outcomes included identifying risk factors for antibiotic treatment, comparing alternative diagnoses for AMS, and comparing safety outcomes. METHODS: This retrospective cohort study evaluated adult patients with AMS and pyuria (10 WBC/hpf) admitted between February 1, 2020 and October 1, 2021, in a 350-bed community teaching hospital. Patients with documented urinary symptoms were excluded. Additional exclusion criteria included admission to critical care, history of renal transplant, urological surgery, coinfections, pregnancy, and neutropenia. RESULTS: Two-hundred patients were included (AMS+Tx, n = 162; AMS-NoTx, n=38). There was no difference in 30-day hospital readmission rate for AMS between groups (AMS+Tx 16.7% vs AMS-NoTx 23.7%, P = 0.311). An alternative diagnosis of AMS occurred more frequently when antibiotics were withheld (AMS+Tx 66% vs. AMS-NoTx 86.8%, P = 0.012). Urinalyses showing bacteria (odds ratio 2.52; 95% CI, 1.11-5.731) and positive urine culture (OR 3.36; 95% CI, 1.46-7.711) were associated with antibiotic prescribing. CONCLUSIONS: Inappropriate antibiotic use is common among hospitalized patients presenting with AMS and pyuria; however, treatment of asymptomatic pyuria did not decrease rates of subsequent readmission for AMS or retreatment of symptomatic UTI. Patients who were monitored off antibiotics had higher rates of alternative AMS diagnosis.

Novel surface biochemical modifications of urinary catheters to prevent catheter-associated urinary tract infections.

More than 70% of hospital-acquired urinary tract infections are related to urinary catheters, which are commonly used for the treatment of about 20% of hospitalized patients. Urinary catheters are used to drain the bladder if there is an obstruction in the tube that carries urine out of the bladder (urethra). During catheter-associated urinary tract infections, microorganisms rise up in the urinary tract and reach the bladder, and cause infections. Various materials are used to fabricate urinary catheters such as silicone, polyurethane, and latex. These materials allow bacteria and fungi to develop colonies on their inner and outer surfaces, leading to bacteriuria or other infections. Urinary catheters could be modified to exert antibacterial and antifungal effects. Although so many research have been conducted over the past years on the fabrication of antibacterial and antifouling catheters, an ideal catheter needs to be developed for long-term catheterization of more than a month. In this review, we are going to introduce the recent advances in fabricating antibacterial materials to prevent catheter-associated urinary tract infections, such as nanoparticles, antibiotics, chemical compounds, antimicrobial peptides, bacteriophages, and plant extracts.

Clinical Differences in Dogs with Enterococcal Bacteriuria Compared with Other Bacteriuria: A Retrospective, Case-Control Study.

A retrospective case-control study was performed to determine the clinical differences between dogs with enterococcal bacteriuria (n = 96 cases) and control dogs with any other bacteriuria (n = 288). More dogs with nonenterococcal bacteriuria demonstrated lower urinary tract clinical signs such as hematuria, pollakiuria, and stranguria (40% versus 27%, P = .02). Recessed vulva (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.4-4.2, P < .001), hyperadrenocorticism (OR 0.149, 95% CI 0.004-0.066, P = .03), chronic kidney disease (OR 2.29, 95% CI 1.14-4.51, P = .01), and myelopathy (OR 5.77, 95% CI 3.07-10.82, P < .001) were more common in dogs with enterococcal bacteriuria. Enterococcus spp. cases were more likely to have polymicrobial growth than controls (OR 28.52; 95% CI 12.63-69.62, P ≤ .001). Pugs (OR 7.4, 95% CI 2.6-19.9, P < .001), bearded collies (OR 24.3, 95% CI 2.9-205.5, P = .003), and Saint Bernards (OR 17.3, CI 1.9-154.4, P = .01) had increased odds of enterococcal growth compared with mixed-breed dogs. In the control (but not the case) population, there was an association between resolution of clinical signs and administration of antimicrobials (P = .01). The signalment, clinical signs, comorbidities, and response to therapy in dogs with enterococcal bacteriuria are different from dogs with other bacteriuria.

Impact of restrictive urinalysis reflex to culture criteria at a large community hospital.

Treatment of asymptomatic bacteriuria (ASB) is a common, but often unnecessary, practice. Our objective was to determine the impact of restrictive urinalysis reflex to culture (UARC) criteria on rate of urine cultures (UC) ordered and ASB treatment. Criteria were modified from positive leukocyte esterase, positive nitrites, or white blood cells (WBC) >10 cells to only WBC >10 cells. This pre-post study evaluated UARCs ordered in the emergency department or inpatient units. The primary outcome was the proportion of reflex UCs prevented. Secondary outcomes included the frequency of repeat UARCs and stand-alone UCs, gram-negative rod (GNR) bacteremia, and ASB treatment. In the pre-intervention, there were 4761 UARCs compared to 5420 in the post-intervention; 37.9 % and 21.4 % reflexed to UCs, a 43.5 % reduction in UCs. The rate of repeat UARCs, stand-alone UCs, and GNR bacteremia in the pre- and post-interventions were similar. ASB treatment rate was numerically lower in the post-intervention.

Assessing clinicians' and trainees' knowledge and practice of the IDSA guidelines for asymptomatic bacteriuria in older adults.

A survey of advanced practice clinicians (APCs), physicians, residents, and medical students at an academic medical center and community practices in southeastern Texas revealed a gap in knowledge and practice related to testing and treatment for asymptomatic bacteriuria (ASB) in older adults.

Performance of an innovative culture-based digital dipstick for detection of bacteriuria.

IMPORTANCE: In this study, we explore the transformative potential of UTI-lizer, an emerging technology not yet commercially available. Our manuscript shows that UTI-lizer is a promising alternative for detecting the five main pathogens that cause urinary tract infections (UTIs). The results also indicate that digital dipsticks have the potential to uniquely provide UTI diagnostic quality on par with that of gold-standard testing, with the added benefits of ease of testing, rapid test handling time, and simple test equipment. This technology can be helpful in quickly ruling out bacterial infections and reducing the unnecessary use of antibiotics, especially in primary care settings or at the point of care. Moreover, the UTI-lizer test can reduce the number of negative urine samples sent to central laboratories, thus easing the burden of UTI diagnostics on the healthcare system. We believe our study, as well as current and upcoming research based on this technology, is highly relevant for clinical microbiologists, microbiology scientists, general practitioners, and urologists.

Diagnostic accuracy of urine biomarkers for urinary tract infection in older women: a case-control study.

OBJECTIVES: Urinary tract infection (UTI) is common among older women. However, diagnosis is challenging because of frequent chronic lower urinary tract symptoms, cognitive impairment, and a high prevalence of asymptomatic bacteriuria (ASB). Current urine diagnostics lack specificity, leading to unnecessary treatment and antimicrobial resistance. This study aimed to evaluate the diagnostic accuracy of 12 urine biomarkers for diagnosing UTI in older women. METHODS: In this case-control study, cases were women ≥65 years with ≥2 new-onset lower urinary tract symptoms, pyuria, and one uropathogen ≥104 CFU/mL. Controls were asymptomatic and classified as ASB (one uropathogen ≥105 CFU/mL), negative culture, or mixed flora. Urine biomarker concentrations were measured through liquid chromatography-mass spectrometry and ELISA. Diagnostic accuracy parameters of individual biomarkers and a biomarker model were derived from receiver operating characteristic curves. RESULTS: We included 162 community-dwelling and institutionalized older women. Five urine inflammatory biomarkers demonstrated high discriminative ability (area under the curve ≥0.80): interleukin 6, azurocidin, neutrophil gelatinase-associated lipocalin, tissue inhibitor of metalloproteinases 2, and C-X-C motif chemokine 9. Azurocidin exhibited the highest diagnostic accuracy (sensitivity 86% [95% CI 75%-93%] and specificity 89% [95% CI 82%-94%] at 16.7 ng/mmol creatinine). A combined biomarker and pyuria model showed improved diagnostic accuracy in patients with UTI and ASB, compared with pyuria alone. DISCUSSION: We identified several urine biomarkers that accurately differentiated older women with UTI from asymptomatic women, including ASB. These findings represent a potential advancement towards improved diagnostics for UTI in older women and warrant validation in a diverse population.

Urinary Tract Infections: Core Curriculum 2024.

Urinary tract infections (UTIs) are some of the most commonly encountered infections in clinical practice. Accurate diagnosis and evidence-based treatment of UTIs will lead to better clinical care for many patients and limit unnecessary antibiotic use. Urinalysis and urine cultures are helpful tools in the diagnosis of UTIs; however, it is important to recognize their limitations. Differentiating between asymptomatic bacteriuria (ASB) and true UTI is important because antibiotics are unnecessary in most nonpregnant patients with ASB and can even potentially cause harm if prescribed. Choice and duration of antibiotics varies across the spectrum of UTI syndromes such as acute uncomplicated cystitis, pyelonephritis, prostatitis, and catheter-associated UTIs. The treatment approach also depends on patients' degree of immunosuppression and their genitourinary anatomy. Therefore, patients with urological obstruction or kidney transplants may require a specialized and multidisciplinary management approach. For individuals prone to frequent UTIs, some preventative measures can be utilized, yet there is often not a "one size fits all" approach.

Management of Asymptomatic Bacteriuria and Urinary Tract Infections in Patients With Neurogenic Bladder and Factors Associated With Inappropriate Diagnosis and Treatment.

OBJECTIVE: Inappropriate diagnosis and treatment of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) are leading causes of antibiotic overuse but have not been well-studied in patients with risks for complicated UTI such as neurogenic bladder (NB). Our aim was to describe ASB and UTI management in patients with NB and assess factors associated with inappropriate management. DESIGN: Retrospective cohort study. SETTING: Four Department of Veteran's Affairs (VA) medical centers. PARTICIPANTS: Adults with NB due to spinal cord injury/disorder (SCI/D), multiple sclerosis (MS), or Parkinson disease (PD) and encounters with an ASB or UTI diagnosis between 2017 and 2018. Clinical and encounter data were extracted from the VA Corporate Data Warehouse and medical record reviews for a stratified sample of 300 encounters from N=291 patients. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Prevalence of appropriate and inappropriate ASB and UTI diagnosis and treatment was summarized. Multivariable logistic regression models assessed factors associated with inappropriate management. RESULTS: N=200 UTI and N=100 ASB encounters were included for the 291 unique patients (SCI/D, 39.9%; MS, 36.4%; PD, 23.7%). Most patients were men (83.3%), >65 years (62%), and used indwelling or intermittent catheterization (68.3%). Nearly all ASB encounters had appropriate diagnosis (98%). 70 (35%) UTI encounters had inappropriate diagnosis, including 55 (27.5%) with true ASB, all with inappropriate treatment. Among the remaining 145 UTI encounters, 54 (27%) had inappropriate treatment. Peripheral vascular disease, chronic kidney disease, and cerebrovascular disease were associated with increased odds of inappropriate management; indwelling catheter (aOR 0.35, P=.01) and Physical Medicine & Rehabilitation provider (aOR 0.29, P<.01) were associated with decreased odds. CONCLUSION: Up to half of UTI encounters for patients with NB had inappropriate management, largely due to inappropriate UTI diagnosis in patients with true ASB. Interventions to improve ASB and UTI management in patients with NB should target complex patients with comorbidities being seen by non-rehabilitation providers.

Asymptomatic bacteriuria in critical-access hospitals: Prevalence and patient characteristics driving treatment.

We evaluated the prevalence and treatment of asymptomatic bacteriuria (ASB) in 17 critical-access hospitals. Among 891 patients with urine cultures from September 2021 to June 2022, 170 (35%) had ASB. Also, 76% of patients with ASB received antibiotics for a median duration of 7 days, demonstrating opportunities for antimicrobial stewardship.

Antibiogram of uropathogens and associated risk factors among asymptomatic female college students in Dessie town, Northeast Ethiopia.

BACKGROUND: Asymptomatic urinary tract infection (asymptomatic bacteriuria and asymptomatic candiduria) may not be routinely detected in sexually active non-pregnant female population at the initial and reversible stages. This is mainly due to the fact that most women may not feel compelled to seek medical attention. OBJECTIVES: The aim of this study was to determine the prevalence, and factors associated with urinary tract infection (UTI), and antibiogram of the uropathogen isolates among asymptomatic female college students. METHODS: An institutional-based cross-sectional study was conducted at selected colleges in Dessie from January 2021-March 2021. A total of 422 reproductive age (15 to 49 years) non-pregnant female students were included. Socio-demographic and clinical characteristics data were collected using structured questionnaires. Ten mLs of freshly voided mid-stream urine specimen was collected, transported and processed according to the standard operating procedures. Data were coded and entered for statistical analysis using SPSS version 22.0. Descriptive statistics, bivariate and multivariate logistic regression analysis were performed and p-values <0.05 with the corresponding 95% confidence interval (CI) were considered statistically significant. RESULT: The overall prevalence of UTI was 24.6%. The prevalence of asymptomatic UTI bacteriuria and candiduria was 57 (13.5%) and 47 (11.1%), respectively. The predominant uropathogens were Staphylococcus saprophyticus 24 (23.1%), followed by Candida tropicalis 23 (22.1%), Candida albican 10 (9.6%), Candida krusei 9 (8.7%) and Escherichia coli 8 (7.7%). Gram negative bacterial isolates showed a higher level of resistance to amoxicillin-clavulanic acid 24 (92.3%). Gram positive bacterial uropathogens showed high level of resistance to penicillin 28 (96.6%) and trimethoprim-sulfamethoxazole 23 (79.3%). Gram positive bacterial isolates were sensitive to norfloxacin, clindamycin, and ciprofloxacin, accounting for 24 (82.7%), 20 (69.0%), and 19 (65.5%), respectively. Multidrug resistance was seen in 50 (87.7%) of bacterial uropathogens. Factors identified for acquisition of UTI were frequency of sexual intercourse (≥3 per week) (AOR = 7.91, 95% CI: (2.92, 21.42), and genital area washing habit (during defecation (AOR = 5.91, 95%CI: (1.86, 18.81) and every morning (AOR = 6.13, 95%CI: (1.60, 23.45)). CONCLUSION: A significant prevalence of uropathogens, and high resistance of bacterial isolates to the commonly prescribed drugs were detected. Therefore, routine UTI screening, regular health education on the risk of asymptomatic infectious diseases for reproductive age group females, and antimicrobial susceptibility testing should be practiced to avoid the progression of an asymptomatic infection into a symptomatic UTI.

BACTERIAL PROFILE, ANTIMICROBIAL RESISTANCE, AND FACTORS ASSOCIATED WITH URINARY TRACT INFECTION AMONG PREGNANT WOMEN AT HOSANNA TOWN HEALTH FACILITIES, CENTRAL ETHIOPIA.

Urinary tract infection in pregnancy is a common microbial infection. Antimicrobial resistance among uropathogens is becoming a major health problem worldwide. The antimicrobial agents used to manage urinary tract infections during pregnancy should be carefully chosen. Therefore, this study aimed to determine the bacterial profile, antibiotic susceptibility pattern, and factors associated with urinary tract infection among pregnant women at Hosanna town public health facilities. A facility-based cross-sectional study was conducted from March to August 2022 on a total of 312 pregnant women who attended antenatal care at Hosanna Town public health facilities. Sociodemographic, clinical data, and related information were collected by using a pre-tested questionnaire. In addition, mid-stream urine specimens were collected from study participants. Bacterial pathogens were identified by standard bacteriological techniques. Antibiotic susceptibility testing was performed by using the Kirby Bauer disk diffusion method. The data were analyzed by using SPSS version 25. Chi-square and odds ratios were calculated and a P-value≤0.05 at a 95% confidence interval was considered statistically significant. The results were presented with words and tables. Of a total of pregnant women, 59/312(18.9%) (95% CI: 14.7-23.7) were found to have significant bacteriuria. The predominant isolates were Escherichia coli (E. coli) 22(34.4%), followed by coagulase-negative staphylococci (CoNS) 10(15.6%), Staphylococci aureus (S. aureus) 7(10.9%), and Klebsiella pneumoniae (K. pneumoniae) 6(9.4%). Overall, 78.1% of these isolates were multidrug-resistant (MDR). Gram-negative bacteria were susceptible to meropenem (97.6%), gentamicin (85.7%), nitrofurantoin (82.1%), ciprofloxacin (73.8%), amoxicillin-clavulanic acid (73.8%) and ceftriaxone (71.8%), but highly resistant to ampicillin (95.5%), trimethoprim-sulfamethoxazole (74.4%), doxycycline (71.8%), cefuroxime (69.2%), and cephalexin (69.2%). The gram-positive bacteria were susceptible to gentamicin (86.4%), erythromycin (81.8%), and nitrofurantoin (77.3%): whereas they showed a high level of resistance to penicillin (72.7%), doxycycline (54.5%), trimethoprim-sulfamethoxazole (52.9%), and cefoxitin (52.9%). No formal education for the participant (AOR: 2.86, 95% CI: 1.03-7.98, p=0.044), family monthly income <1500 birr (AOR: 3.19, 95% CI: 1.48-6.89, p=0.003), and previous history of UTI (AOR: 4.52, 95% CI: 2.04-10.03, p=0.001) were significantly associated with bacteriuria. This study revealed a high prevalence of bacterial urinary tract infection among pregnant women and low susceptibility to ampicillin, trimethoprim-sulfamethoxazole, cefuroxime, and cephalexin. Therefore, regularly, culture-based bacterial identification and antibiotic susceptibility testing should be performed. Alternatively, empiric antibiotic therapy should consider the prevalence of antibiotic-resistant uropathogens and the factor that may increase the urinary tract infection occurrence due to multi-drug resistant uropathogens.
