Impact of a structured urine culture request form on antimicrobial stewardship in urinary tract infections at a tertiary care hospital in India.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Interpretation of urine culture results requires key clinical information such as symptom status, catheterization, and multidrug-resistant organism (MDRO) risk. However, this information is frequently absent from routine request forms, contributing to overtreatment of asymptomatic bacteriuria (ASB) and suboptimal antimicrobial prescribing. This study evaluated the impact of implementing a structured urine-culture request form as part of a diagnostic and therapeutic stewardship program. Methods: This prospective, non-randomized interventional study was conducted at an 1800-bed tertiary-care hospital in India (March 2023-March 2024). Patients undergoing urine culture testing in Urology/Nephrology departments used a structured request form capturing symptoms, risk factors, and clinical context (test arm), while General Medicine continued routine forms (control arm). Primary outcomes included ASB treatment, MDRO detection, recurrence, and guideline-concordant prescribing. Patients were followed for one year. Results: A total of 484 patients were included (198 test arm, 286 control arm). Antibiotic treatment for ASB was significantly lower in the test arm compared with the control arm (3.6% vs 67.0%; p < 0.001), without adverse outcomes. Guideline-compliant prescribing was higher in the test arm (73.7% vs 26.2%; p < 0.001). MDRO prevalence was higher in the test arm (32.2% vs 11.3%), reflecting greater clinical complexity rather than the intervention itself. Recurrent urinary tract infection (UTI) within one year was significantly lower in the test arm (14.1% vs 29.0%; p < 0.001). Conclusions: Introducing a structured urine-culture request form improved diagnostic clarity and antibiotic prescribing, particularly by reducing unnecessary treatment of ASB and increasing guideline compliance, without compromising patient outcomes. This low-cost intervention represents a practical and scalable diagnostic stewardship strategy for improving UTI management.
