Improving urine culture appropriateness and reducing unnecessary testing through education and feedback in a hospital setting.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo evaluate the impact of an educational intervention on the appropriateness of urine culture indications and overall urine culture trends.
methodsA quasi-experimental study in six medical wards of an acute care hospital included a pre-intervention phase (Jan 2019-Dec 2021) and an intervention phase (Jan 2022-Dec 2023). The intervention comprised educational sessions, best practice guidelines, and feedback. Urine culture appropriateness was assessed by reviewing a sample of 360 records from both periods. Bivariate and multivariable logistic regression identified predictors of appropriate urine cultures, and time-series analysis assessed trends in culture rates.
resultsThe median age of patients was 81 years (IQR 70.1-87.0), with no differences between the two periods in age, sex, residence in long-term care, or comorbidities. The appropriateness of urine cultures increased significantly from 43.9% (79 of 180 patients) in the pre-intervention period to 56.7% (102 of 180 patients) in the post-intervention period (p = 0.015). The intervention period (OR 1.66; 95% CI, 1.07-2.57; p = 0.023) and younger age (OR, 0.97; 95% CI, 0.95-0.99; p < 0.001) were significantly associated with improved appropriateness. Urine culture rates showed no significant pre-intervention trends (p = 0.19) but decreased by 18% post-intervention (p < 0.001).
conclusionsYounger age and the intervention period were associated with reduced unnecessary urine cultures and improved adherence to appropriate practices. These findings highlight the importance of ongoing educational initiatives and feedback in enhancing diagnostic stewardship.
