Function evaluation of intelligent interaction voice prompting system on personal protective equipment removal for medical staff.
Article in BMC health services research, 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
backgroundThis study aimed to evaluate the effectiveness of an intelligent interaction voice prompting system (IIVPS) for guiding medical staff in the removal of personal protective equipment (PPE).
methodsA total of 152 medical staff members were enrolled via convenience sampling. Using a one-group pretest-posttest design, system effectiveness was evaluated by comparing pre- and post-intervention PPE removal accuracy, psychological stress, and operational fatigue, with nonparametric tests for statistical analyses. User experiences and suggestions for improvement were collected via questionnaires and face-to-face interviews.
resultsAll participants achieved correct PPE-removal procedure adherence while using the IIVPS. The use of the IIVPS was associated with a significant increase in PPE-removal accuracy from 78% to 100% (P < 0.001). The median psychological stress score decreased from 3.00 (3.00, 4.00) to 2.00 (1.00, 2.00) (Z = -8.610, P < 0.001), and the median operational fatigue score decreased from 3.00 (3.00, 4.00) to 1.50 (1.00, 2.00) (Z = -9.172, P < 0.001). Significant differences in system mastery were observed based on PPE training history and familiarity (P < 0.05), while learning acceptance varied by age, work experience, and PPE familiarity (P < 0.05). Analysis of qualitative feedback revealed overwhelmingly positive responses (95.39%), with key themes including "effective operational guidance" and "stress reduction".
conclusionsThe IIVPS may effectively guide medical staff in standardised PPE removal and potentially reduce psychological stress and operational fatigue. However, this study's one-group design and short-term evaluation limit causal inferences, and long-term effectiveness requires verification via randomised controlled trials (RCTs). The system shows promising potential for clinical application and training. CLINICAL TRIAL NUMBER: Not applicable.
