Application scope of digital health technologies in pressure injury prevention:a scoping review

Objective: To conduct a scoping review on the application of digital health technologies in the prevention of pressure injuries (PI), with the aim of providing reference and evidence for guiding future research directions in PI prevention. Methods: Based on the Arksey and O'Malley framework, the included literature was screened, summarized, and analyzed. A total of nine databases were searched, including PubMed, Embase, Web of Science, CINAHL, Cochrane Library, CNKI, Wanfang, VIP, and China Biomedical Literature Database, with the search period from database inception to November 2025. Results: A total of 28 studies were included, and the digital health technologies used comprised five categories: mobile health platforms, applications, wearable devices, computer vision, and virtual reality technologies. Interventions included prediction and assessment, alerts and reminders, decision-making and guidance, recording and analysis, and education and training. Outcome indicators included reducing PI incidence, optimizing nursing workflows, cost-effectiveness, safety management, application effectiveness, reducing workload, and improving knowledge and skill levels. Conclusion: Overall, digital health technologies have good application value in PI prevention, but high-quality clinical trials are still needed in the future to further verify the long-term efficacy of digital health technologies.
