Article Abstract
Objective: Urine cultures collected from catheterized patients have a high likelihood of false-positive results due to colonization. We examined the impact of a clinical decision support (CDS) tool that includes catheter information on test utilization and patient-level outcomes.
Methods: This before-and-after intervention study was conducted at 3 hospitals in North Carolina. In March 2021, a CDS tool was incorporated into urine-culture order entry in the electronic health record, providing education about indications for culture and suggesting catheter removal or exchange prior to specimen collection for catheters present >7 days. We used an interrupted time-series analysis with Poisson regression to evaluate the impact of CDS implementation on utilization of urinalyses and urine cultures, antibiotic use, and other outcomes during the pre- and postintervention periods.
Results: The CDS tool was prompted in 38,361 instances of urine cultures ordered in all patients, including 2,133 catheterized patients during the postintervention study period. There was significant decrease in urine culture orders (1.4% decrease per month; < .001) and antibiotic use for UTI indications (2.3% decrease per month; = .006), but there was no significant decline in CAUTI rates in the postintervention period. Clinicians opted for urinary catheter removal in 183 (8.5%) instances. Evaluation of the safety reporting system revealed no apparent increase in safety events related to catheter removal or reinsertion.
Conclusion: CDS tools can aid in optimizing urine culture collection practices and can serve as a reminder for removal or exchange of long-term indwelling urinary catheters at the time of urine-culture collection.

Two recent Phase 3 trials demonstrated the efficacy of gepotidacin compared with nitrofurantoin to treat uncomplicated urinary tract infections (uUTIs) in females. Pretreatment urine specimens were obtained from all participants. Based on pooled trial data (treatment groups combined), central laboratory culture results identified 1,421 (45%) participants with ≥1 baseline qualifying (≥10 CFU/mL) uropathogen (i.

Rationale: Primary polydipsia refers to excessive water intake due to psychogenic or non-psychogenic causes without being secondary to conditions such as hyperglycemia or renal dysfunction. Most cases of primary polydipsia are psychogenic in nature, with few cases of non-psychogenic primary polydipsia reported in the literature. In this case, the patient's excessive water intake appeared to be influenced by both psychogenic and non-psychogenic factors.

Purpose Of Review: Diagnostic stewardship (DS) aims to optimise the use of laboratory testing to improve patient care while reducing unnecessary tests. This review examines recent evidence on DS interventions to optimise the use of resources, focusing on three key areas: reducing unnecessary testing, maximising the impact of existing tests, and avoiding the overdiagnosis of hospital-acquired infections.
Recent Findings: Multiple interventions have demonstrated effectiveness in reducing unnecessary blood and urine culture testing, including clinical decision support tools, education programs, and multidisciplinary approaches.

Background: commonly colonizes the genitourinary tract and primarily affects immunocompromised individuals. It is mostly confined to localized infections, with bloodstream dissemination being rare. Because of its fastidious nutritional requirements, the organism is seldom recovered by routine blood culture, and the absence of a cell wall renders it intrinsically resistant to many first-line antimicrobials.

Background Diabetes mellitus is a global public health challenge, significantly increasing susceptibility to infections, particularly urinary tract infections (UTIs). Diabetic patients face a higher risk of recurrent and complicated UTIs due to impaired immune function, poor glycemic control, and associated comorbidities. Objective This study aimed to determine the frequency and demographic trends of hospital admissions in diabetic patients suffering from urinary tract infections, identify associated clinical risk factors, evaluate the microbiological profile of uropathogens, and assess prevailing patterns of antimicrobial resistance.
