Forearmed is forewarned: A prospective intervention observational time-series study of patient empowerment for ultrasound-guided peripheral intravenous access.
Observational study in Emergency medicine Australasia : EMA, 2022. 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
objectiveUltrasound (US) is a valuable adjunct to improve the success rates of difficult peripheral intravenous cannula (PIVC) insertions but is usually clinician initiated. The present study assessed for any change in clinician practice resulting from interventions aimed at empowering patients to advocate for early use of US if they self-identified as having difficult PIVC access.
methodsThis was a prospective observational time-series study using a rapid quality improvement (RQI) framework. Three ED waiting room intervention strategies (printed media, video and wristband) were tested over three 2-week periods at a large teaching hospital. The impact of each intervention was assessed at eight time points during each intervention and compared to a pre-intervention baseline period using trend and time-series analysis.
resultsA total of 1611 PIVC insertions were surveyed over 42 time points. The proportion of US-guided PIVC insertions was highest during Intervention 3 (wristbands; 5.5%) but all proportions remained below baseline (6.5%). Trend analysis identified an increasing frequency of US use during Intervention 1 (printed media, P = 0.01). However, no statistically significant trends were observed within the periods.
conclusionsThis is the first prospective study to assess the effect of various interventions to empower patients to self-identify as having difficult PIVC access and advocate for the use of US-guidance. The present study was indeterminate: no intervention tested in the present study noticeably influenced clinical practice, potentially attributable to the study design and confounding factors. This innovative study serves as a pilot for future research into patient empowerment, which is currently lacking in the literature.
