Objective: To evaluate the impact of the Internet Plus multi-party collaborative family bed model on activities of daily living, nutritional risk, and pressure injury in elderly patients. Methods: A total of 200 elderly patients with family beds from 8 community health service centers in Futian District, Shenzhen, from January 2025 to October 2025 were selected as study subjects. They were randomly divided into an observation group and a control group (100 cases each) using the random number table method. The observation group received conventional family bed services from community health doctors, while the control group received additional specialist home monitoring and remote consultations based on the observation group. The Barthel Index, Nutritional Risk Screening 2002 (NRS-2002), Braden Scale for pressure injury risk, and satisfaction level were compared between the two groups 90 days after establishing the family bed. Results: After intervention, the control group's Barthel Index score was significantly higher than that of the observation group (P<0.05), while the NRS-2002 nutritional risk score and Braden pressure injury risk score were significantly lower than those of the observation group (P<0.05). The control group's satisfaction level was also significantly higher than that of the observation group (P<0.05). Conclusion: The Internet Plus multi-party collaborative family bed model is beneficial for improving elderly patients' activities of daily living, reducing nutritional risk and pressure injury incidence, and improving patient satisfaction, providing practical evidence for optimizing home-based elderly care service models.
