Digital Multimedia in Clinical Nurse Education for Pressure Injury Prevention Via LINE@

Overview

The goal of this clinical trial is to integrate past indicators affecting the effectiveness of pressure injury care education among nurses and to explore the learning outcomes of nurses through different educational interventions. The main questions it aims to answer are: What are the outcomes of nurses' knowledge, attitudes, and self-efficacy in preventing pressure injuries after receiving education through traditional media? What are the outcomes of nurses' knowledge, attitudes, and self-efficacy in preventing pressure injuries after receiving education through digital multimedia combined with practical courses? What is the satisfaction level of nurses with pressure injury prevention education after receiving education through traditional media or digital multimedia combined with practical courses?

I. Research Objectives: To explore the effectiveness of different educational strategies on clinical nurses' prevention of pressure injuries. II. Research Design: A quasi-experimental design with purposive sampling, targeting clinical nurses from a regional teaching hospital. The participants are divided into a control group and an experimental group. The study focuses on pressure injury prevention, using digital media materials to present teaching content. The impact of digital media materials combined with practical courses on learning outcomes is examined. The control group will use digital media materials only, while the experimental group will use digital media materials and participate in a half-day practical course. Pre- and post-tests will be conducted for both groups before and after the course. III. Research Subjects: The study subjects are clinical nurses from a regional teaching hospital in central Taiwan. Inclusion criteria are: (1) full-time or part-time nursing staff registered at the research site, engaged in frontline clinical care or nursing administration, and (2) willing to participate and provide informed consent. Exclusion criteria are nursing interns. Participants who do not complete the entire training course (i.e., leave midway or terminate participation) will be excluded to avoid affecting the measurement of research outcomes. Sample size calculation is based on G\*power 3.1.7. Given that educational training has a moderate effect on nurses' knowledge and skills (Taylor-Piliae, 2008) and using Cohen's effect size analysis (Cohen, 1992), with a two-tailed test, α set at .05, power at 0.95, and effect size at 0.8, each group requires 42 samples. Considering a 40% dropout rate, 118 participants are planned, with 59 in the experimental group and 59 in the control group. IV. Research Tools: Digital Media Materials: Based on the 2019 international clinical practice guidelines for pressure ulcer prevention and treatment by the National Pressure Injury Advisory Panel (NPIAP), European Pressure Ulcer Advisory Panel (EPUAP), and Pan Pacific Pressure Injury Alliance (PPIAP), and the curriculum outline of the Taiwan Wound and Ostomy Care Society, four multimedia digital videos focused on pressure injury prevention are designed as the main study materials. Demographic Data of Nurses: Including age, gender, marital status, education level, nursing rank, years of work experience, daily working hours, work unit, perceived workload, and past learning experience on pressure injuries, totaling 12 items. Knowledge Questionnaire: Developed by Pieper and Mott in 1995 to assess healthcare workers' knowledge of pressure injury prevention. It includes questions on pressure ulcer prevention, staging, and description, with modifications to better suit healthcare settings. The final version is the 72-item Pieper-Zulkowski Pressure Ulcer Knowledge Test updated in 2021, with 31 items focused on prevention. Attitude Questionnaire: Developed by Moore and Price in 2004 to assess nurses' attitudes toward pressure ulcer prevention. It includes 11 items rated on a Likert scale from 1 (strongly agree) to 5 (strongly disagree), with items 1, 6, 7, and 11 reverse scored. Scores range from 11 (most negative attitude) to 55 (most positive attitude). Self-Efficacy Questionnaire: PUM-SES, published in 2019, assesses nurses' self-efficacy in managing pressure injuries. It includes 10 items across four domains: assessment, planning, supervision (two items each), and decision-making (four items). The scale uses a 5-point Likert scale, with scores ranging from 1 (cannot) to 5 (completely capable), total score from 10 to 50. V. Research Steps: Through verbal promotion and unit supervisor recommendation, recruit willing nursing staff to participate in the study. An information session is held to explain the research process, obtain consent, and complete pre-tests and the viewing of four multimedia digital courses on pressure injury prevention. Control Group: After the information session, a PDF link to the pressure injury prevention course will be placed on the Nursing Information System (NIS) login interface, allowing nurses to view or download it at their convenience. A digital learning platform is also provided for downloading the self-study course materials. Experimental Group: After the information session, join LINE@, which provides multimedia teaching materials and clinical scenario-based learning on a digital platform. The course includes basic knowledge learning, quizzes, and unit reviews, accessible anytime and anywhere. The digital platform continuously prompts pressure injury-related care questions and key points to stimulate learning motivation, encouraging discussion and brainstorming in the platform's discussion area.
