Abstract: Objective: To investigate the incidence and influencing factors of Chronic Post-Traumatic Pain (CPTP) in patients with acute trauma at 3 months post-injury, and to provide a reference for the early clinical management of pain in patients with acute trauma. Methods: A convenience sampling method was used to enroll 118 patients admitted to the trauma center of a tertiary grade A hospital in Beijing from January to December 2024. In-hospital acute pain management status of the patients were collected. The occurrence of CPTP was followed up at 3 months after trauma, and binary Logistic regression analysis were used to identify the influencing factors. Results: The incidence of CPTP was 38.1%. Logistic regression analysis showed that the worst pain intensity within 48 hours post-trauma, the worst pain intensity within 48 hours post-surgery, the number of presses of the postoperative analgesic pump within 48 hours post-surgery, whether pain medications were prescribed at discharge and long-term alcohol consumption history were influencing factors for CPTP. Conclusion: The incidence of CPTP is relatively high in patients 3 months after acute trauma. The worst pain intensities within 48 hours post-trauma and post-surgery are major influencing factors for the development of CPTP. Nurses should intervene as early as possible to improve the effectiveness of pain management in patients.
