Abstract: Objective: To summarize the content, outcome indicators and application effects of Virtual Reality (VR) technology in patients with Maintenance Hemodialysis (MHD). Methods: A literature search was performed in Chinese and English databases from inception to May 15, 2022 to retrieve relevant studies. The framework proposed by Arksey and O'Malley was used to conduct the scoping review. Two researchers independently summarized and analyzed data. Results: A total of 9 studies were included. Physical training based on non-immersive VR was the main type of VR technology intervention for MHD patients, with a frequency of 3 times per week, lasting 30-60 minutes per session of 4-24 weeks during dialysis, and intervention intensity based on the Rating of Perceived Exertion of patients with MHD. VR technology can improve the physical function and health-related quality of life of MHD patients to some extent, but whether it can improve mental health was still controversial. No adverse events and well acceptability of VR technology intervention were reported among MHD patients. Conclusion: VR technology intervention has a positive effect on MHD patients and is safe and feasible. Large sample and more high quality experiments are needed to provide evidence-based basis for formulating the best VR technology intervention plan for MHD patients.
