Effect of an educational intervention on nurses' knowledge, attitudes, and practices in adherence to pressure injury prevention: a randomized controlled trial.
Article in BMC nursing, 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
backgroundPressure injuries are a significant preventable cause of patient injury, and nurses' adherence to evidence-based preventive strategies is essential. Systematic education could enhance knowledge, attitudes, and preventive actions beyond conventional in-service training. This study aimed to determine the effect of an educational intervention on nurses' knowledge, attitudes, and practices related to adherence to pressure injury prevention guidelines compared with routine education.
methodsA parallel-group, randomized controlled trial was conducted between January 1 and March 5, 2026 in a tertiary hospital in Riyadh, Saudi Arabia, including 222 registered nurses (n = 111 each for intervention and control) recruited from high-acuity and general inpatient settings. The intervention comprised structured education delivered through didactic lectures, interactive discussions, case-based learning, and practical demonstrations, supplemented with printed handouts and reinforcement reminders. The assessments were conducted using validated knowledge, attitudes, practice, and adherence measurement instruments. Independent samples t-tests were used for initial comparisons.
resultsThe baseline characteristics and pre-intervention scores were comparable between the groups. Post intervention, the structured education group demonstrated significantly higher knowledge (t(220) = - 36.08, p < .001), attitude (t(220) = - 50.62, p < .001), practice (t(220) = - 28.43, p < .001), and adherence scores (t(220) = - 42.86, p < .001) than the routine group. An analysis of covariance confirmed significant group effects after adjusting for baseline values, with large effect sizes were observed across outcomes, with Cohen's d ranging from 3.80 to 6.80, for knowledge (η² =0.905), attitude (η² =0.938), practice (η² =0.800), and adherence (η² =0.932). Regression analysis showed that post-intervention knowledge, attitude, and practice explained 83.6% of the variance in adherence (R² =0.836), with attitude emerging as the strongest predictor (β = 0.470, p < .001).
conclusionsStructured education produced substantial improvements in nurses' knowledge, attitudes, practice, and adherence in relation to PIP protocols. Attitudinal change plays a pivotal role in enhancing adherence. Integrating structured, competency-based educational programs into routine professional development may strengthen patient safety and reduce preventable PIs.
