【Abstract】Objective To investigate the correlation between quality of life and coping style in elderly patients with intracranial aneurysm after operation and the influencing factors. Methods A retrospective study was conducted on 140 elderly patients with intracranial aneurysms undergoing surgical treatment in our hospital from March 2021 to May 2023. The coping styles of the patients were assessed by social coping style questionnaire, and their quality of life was assessed by quality of life questionnaire core 30 (QLQ-C30) before and after surgery. SPSS statistics 20.0 was used for statistical analysis. Data comparison between two groups was performed using t-test orχ2 test depending on data type. Pearson correlation analysis was used to analyze the correlation between quality of life and coping style, and logistic regression was employed to analyze the influencing factors for postoperative quality of life in elderly patients with intracranial aneurysm. Results After treatment, the total score of quality of life, scores of social function, emotional function, role function, cognitive function, and physical function, and face-to-face score in coping strategies were all higher, while the avoidance and yield scores in coping strategies were lower than the corresponding scores before operation (all P<0.05). Correlation analysis showed that the postoperative quality of life of the elderly patients with intracranial aneurysm was positively correlated with face-to-face coping, and negatively correlated with avoidance and yielding coping (r=0.840, -0.646, -0.487; P<0.05). Multivariate logistic regression analysis indicated that clamping as surgical treatment (OR=3.912,95%CI 1.406-10.882), posterior circulation aneurysm (OR=4.811,95%CI 1.348-17.168), postoperative complications (OR=3.939,95%CI 1.405-11.045), aneurysm diameter >25 mm (OR=4.948,95%CI 1.376-17.794), Hunt-Hess Grade Ⅲ (OR=4.336; 95%CI 1.291-14.560), and negative coping style (OR=4.581,95%CI 1.304-16.093) were independent risk factors affecting postoperative quality of life in elderly patients with intracranial aneurysm (P<0.05). Conclusion In elderly patients with intracranial aneurysms, their postoperative quality of life is significantly correlated with coping styles. Surgical treatment of clamping, having aneurysm at posterior circulation artery, postoperative complications, aneurysm diameter >25 mm, Hunt-Hess grade Ⅲ, and negative coping styles are independent risk factors affecting their postoperative quality of life. Clinicians should pay more attention to these factors and take measures actively.
