Evaluating the effectiveness of the SHEL model in reducing occupational exposure risks among pre-hospital emergency personnel: a retrospective cohort study (2018-2024).

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
Background: Pre-hospital emergency personnel face significant occupational exposure risks, yet traditional training approaches often prove inadequate. This study evaluated the effectiveness of SHEL (Software, Hardware, Environment, Liveware) model-based training versus standard operating procedure training (SOPT) in reducing occupational exposure incidents. Methods: This retrospective cohort study included pre-hospital emergency personnel from an emergency center between January 2018 and June 2024. Participants were divided into SOPT and SHEL groups based on the training received. Knowledge, Attitude, and Practice (KAP) scores and safety behavior compliance were assessed before and 6 months after training. Occupational exposure incidents and root causes were analyzed throughout the one-year follow-up. Psychological status was evaluated using the Nursing Stress Scale and Maslach Burnout Inventory before and 6 months post-training. Results: The analysis included 129 and 114 staff in the SOPT and SHEL groups, respectively. Six months post-training, the SHEL group demonstrated significantly higher KAP scores and safety behavior compliance (86.41 vs. 79.83, Conclusion: Training based on the SHEL model is more effective than traditional SOPT in enhancing occupational safety, reducing exposure incidents, and improving the psychological well-being of pre-hospital emergency personnel. These findings support the need for more integrated training approaches in emergency medical services.
