Objective To develop a precision rewarming information platform for hypothermia management in emergency trauma patients, and to evaluate its application effectiveness. Methods A quasi-experimental study design was employed. Emergency trauma patients were divided into two groups: 84 patients admitted before the implementation of the information platform (a control group) and 84 patients admitted after its implementation (an intervention group). The control group received routine temperature management, whereas the intervention group received precise hypothermia intervention guided by the information platform. Results Following the implementation of the precision rewarming information platform for hypothermia management, the intervention group demonstrated a significantly shorter time to completion of first-level rewarming measures compared to the control group, and nurses′ adherence to temperature monitoring protocols was significantly higher than that of the control group, moreover, patients in the intervention group had significantly higher body temperatures at 30 minutes after admission and 1 hour post-rewarming (all P<0.05). Nurses′ satisfaction with the platform ranged from 90.2% to 97.8%. Conclusion The application of the precision rewarming information platform for emergency trauma patients with hypothermia facilitates earlier initiation of rewarming interventions, enhances rewarming efficiency, optimizes emergency resource utilization, and achieves high levels of nurse satisfaction.
