Function evaluation of intelligent interaction voice prompting system on personal protective equipment removal for medical staff

Background This 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). Methods A 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. Results All 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”. Conclusions The 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.
