Application of Key Link Nursing Based on Feedforward Control Theory in the Emergency Rescue of Multiple Trauma Patients

Q: What is the study’s objective?

To explore the application effect of key link nursing based on feedforward control theory in the rescue of emergency patients with multiple injuries.

Q: How were patients grouped in the study?

A total of 120 multiple-injury patients were divided into a conventional group receiving conventional emergency care and a feedforward control group receiving key-link nursing interventions guided by feedforward control theory.

Q: What improvements were observed in the feedforward control group?

The group had significantly lower emergency-to-care and treatment times, lower MODS/DIC incidence, lower referral and complication rates, higher handling/communication/explanation and rescue skills, higher preparation and satisfaction scores, and improved SF-36 dimension scores.

This original research evaluates how key link nursing informed by feedforward control theory affects emergency rescue outcomes for multiple trauma patients. A total of 120 patients were assigned to conventional emergency care or a feedforward control group receiving nursing interventions across key links. The study compares emergency timing, treatment effects, family nursing satisfaction, complication rates, and trauma severity, showing improved rescue efficiency, reduced MODS/DIC and complications, lower post-treatment severe injury proportion, and higher process, communication, rescue skill, preparation, satisfaction, and SF-36 dimension scores.

Application of key link nursing based on feedforward control theory in the emergency rescue of multiple trauma patients Yufeng Huang†, Fei Yin†, Yuehua Ni, Ying Zhang and Chen Dai * Department of Emergency, Ninth People’s Hospital of Suzhou City, Suzhou, China Objective: To explore the application effect of key link nursing, which is based on feedforward control theory, in the rescue of emergency patients with multiple injuries. Methods: A total of 120 patients with multiple injuries admitted to the emergency department of Suzhou Ninth People’s Hospital from August 2022 to February 2025 were included in the study and grouped according to different emergency modes: 46 patients with multiple injuries were included in the conventional group (conventional emergency care), and 74 patients were included in the feedforward control group (nursing intervention in key links on the basis of feedforward control theory) . The emergency time, treatment effect, patient family nursing satisfaction, complication rate and trauma severity of the feedforward control group and the conventional group were compared. Results: Compared with those in the conventional group, the time to establish intravenous access, the time to complete systemic examination, the time to stay in the emergency department, the time from the emergency department to the operating room, the incidence rates of MODS and DIC, the referral rate and the incidence of complications in the feedforward control group were significantly lower. Compared with those of the conventional group, the process handling, communication explanation, rescue skills, prepreparation score, nursing satisfaction score and scores of each dimension of the SF-36 significantly increased (p < 0.05) . The proportion of severe injuries in the feedforward control group after treatment was significantly lower than that in the conventional group (p < 0.05) . Conclusion: Key link nursing based on feedforward control theory can improve the rescue success rate of emergency patients with multiple injuries, shorten the rescue time, improve the severity of patients’ injuries, reduce the occurrence of complications, effectively improve management satisfaction, and improve patients’ quality of life.
