A Coloured Pen Needle Education System Improves Insulin Site Rotation Habits: Results of a Randomized Study.

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
introductionNeedle reuse and repeated injection of insulin into the same site encourage lipohypertrophy. We explored the potential of coupling a novel pen needle strategy with community pharmacists to improve injection site rotation.
methodsBetween October 2018 and January 2019, adult insulin users with type 1 or 2 diabetes were enrolled by 16 community pharmacists across 7 Canadian provinces and randomized to their usual pen needles (control) or coloured pen needles packaged with education materials in boxes with reminder sound chips (intervention [mCPN]). A total of 203 individuals completed all requirements of the 30-day study. The primary outcome was a composite of the number of zones injected, the use of new injection zones if the number of zones equaled that at baseline, and the change in size of the injection area from baseline. The pharmacists completed two questionnaires, which provided insights into whether study participation elevated their comfort and confidence in providing injection site rotation counselling.
resultsCompared to the control group, more participants in the mCPN arm improved their site rotation practices (54.1% vs. 33.7%; P = 0.005), 15 more increased the number of injection zones used (P = 0.03), and there was less needle reuse (25% vs. 12% reduction). The pharmacists reported improved knowledge of the consequences of lipohypertrophy and the proportion who were "very comfortable" with pen needle tip selection and use rose from 31.3% pre-study to 93.8% post-study.
conclusionThe coloured pen needles with their education materials are a novel means of encouraging injection site rotation. Community pharmacists represent an untapped resource for improving injection self-care practices.
