Abstract:

Objective To explore the occurrence and influencing factors of post-traumatic stress disorder (PTSD) in patients with severe trauma. Method Take the patients with severe trauma who were revisited in the outpatient department from June 2020 to May 2021 as the subjects of investigation, and carry out cross-sectional investigation and research. After obtaining their consent, the hospital information management system will first collect the cause of injury, trauma site, trauma time, and trauma severity score (ISS); They were given the social demographic data questionnaire, the posttraumatic stress disorder self-rating scale (PTSD-SS), the Chinese version of the selfrating scale of sleep (SRSS) and the positive psychological capital questionnaire (PPQ) to investigate their social demographic data, the degree of post-traumatic stress disorder, sleep status and positive psychological status. Result

A total of 187 cases were included in the final analysis. The PTSD-SS scale score ranged from 5 to 78 points, with an average of (47.27±11.60) points. 53 cases (28.34%) were diagnosed with PTSD (PTSD group), and 134 were non-PTSD (non-PTSD group). There were statistically significant differences between the PTSD group and the Non-PTSD group in terms of education level, family income level, trauma time, ISS total score, SRSS total score and PPQ total score (P ＜ 0.05); Logistic regression analysis showed that high family income level, long trauma time and high PPQ score were protective factors for PTSD in severely traumatized patients (P ＜ 0.05). Conclusion The risk of PTSD after severe trauma is higher. Family income level, trauma time and positive psychological status are the influencing factors of PTSD after severe trauma.
