A qualitative evaluation of a program to implement antimicrobial stewardship for asymptomatic bacteriuria: how site attributes affected uptake.
Article in Infection control and hospital epidemiology, 2026. 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
objectiveDetermine site attributes affecting uptake of a national, multi-site antimicrobial stewardship project focused on reducing unnecessary urine culture orders and antibiotic prescriptions for asymptomatic bacteriuria (ASB).
methodsForty-one United States Veterans Affairs Medical Centers (VAMCs) were randomized into two arms: "Technical Assistance" (TA) or the "Virtual Learning Collaborative" (VLC). TA sites could request one-on-one guidance from the coordinating center, and VLC sites participated in semimonthly informational webinars. Otherwise, we provided TA and VLC sites with the same resources to educate healthcare professionals on proper ASB management. At the intervention's conclusion, we conducted 45-60-minute semi-structured interviews with local site leads and focus groups with their teams. TA and VLC sites were sampled based on time spent on intervention implementation, resulting in 19 participants across varying roles (e.g., pharmacists, physicians). We iteratively coded transcripts using thematic analysis.
resultsWe propose five considerations for how site attributes informed uptake of our stewardship initiative: (1) existing connections with leadership and important contacts; (2) workplace structure and culture; (3) previous and concurrent antimicrobial stewardship initiatives; (4) availability of existing resources (e.g., time); and (5) personnel turnover (e.g., daily provider transition, job turnover).
conclusionsWe recommend conducting pre-intervention interviews to identify site-specific obstacles and then tailoring the intervention to site-specific needs. Additionally, we stress the importance of sites' prior experiences with antibiotic stewardship and the availability of personnel to work on stewardship initiatives. Ultimately, a better understanding of sites' unique environments is an essential step for improving uptake of antimicrobial stewardship projects.
