Enhancing Safety in Clinical Practice: Cross-Sectional, Within-Subjects, Simulated-Use Compliance Study Using BD PosiFlush SafeScrub.
Article in JMIR human factors, 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
backgroundNeedleless access devices are essential for intravenous therapy but can be a source of contamination and catheter-related bloodstream infections (CRBSIs) if not disinfected properly. The BD PosiFlush SafeScrub (Becton, Dickinson and Company) is designed to support aseptic nontouch technique (ANTT) by incorporating a built-in reminder to "scrub-the-hub" before flushing. This feature can help improve compliance with disinfection practices and may reduce the risk of microbial contamination.
objectiveThis study aimed to evaluate compliance with scrubbing before flushing using the BD PosiFlush SafeScrub in a simulated clinical environment compared with standard disinfection and flushing practices (alcohol swabs and prefilled saline syringes).
methodsA cross-sectional, within-subjects, simulated-use compliance study was conducted with health care professionals familiarized with BD PosiFlush SafeScrub (a prefilled BD PosiFlush Syringe with an integrated disinfecting unit). Compliance was defined according to the disinfection procedure specified for each scenario; participants were considered compliant with standard practice if they followed their own institutional policy (ranging from 5 to 30 seconds or based on stroke counts), while compliance with BD PosiFlush SafeScrub required scrubbing for at least 10 seconds with a minimum of 8 clockwise and 8 counterclockwise rotations, in accordance with the instructions for use (IFU). Compliance with disinfection was monitored and recorded for both the BD PosiFlush SafeScrub and standard disinfection and flushing practice.
resultsCompliance with catheter hub disinfection was assessed among 60 participants for BD PosiFlush SafeScrub and 57 participants for standard practice. During preaccess procedures (Flush 1), BD PosiFlush SafeScrub achieved 46% compliance versus 21% with standard practice, representing an absolute improvement of 25% and a 119% relative improvement (P<.001). During the postmedication procedure (Flush 2), compliance was 22% with BD PosiFlush SafeScrub compared with 13% for standard practice, corresponding to a 9% absolute improvement and 69% relative improvement, although not statistically significant (P=.12). Overall, the compliance rate was 34% (81/240 interactions) in the BD PosiFlush SafeScrub group compared with 17% (39/228 interactions) in the standard practice group, representing an absolute improvement of 17% and a relative improvement of 100% (P<.001).
conclusionsThe BD PosiFlush SafeScrub, with its integrated disinfection unit, yielded approximately double the scrub-the-hub compliance (34%) before flushing compared to the standard practice of alcohol pads and prefilled saline syringes (17%), supporting its role in facilitating adherence to ANTT, which may reduce microbial growth.
