584 The effects of a co-management care model on older hip fracture patients with psychological disorders: a post-hoc exploratory subgroup analysis of a non-randomised controlled trial

<h3>Backgroud</h3> Psychological disorders, including depression, fear of falling, and cognitive disorders, are common among elderly patients with hip fractures. The effectiveness of a co-management care model in elderly hip fracture patients has been established, but its impact on those with psychological disorders remains unclear. <h3>Objective</h3> This study aims to investigate the effects of a co-management care model on elderly hip fracture patients with psychological disorders. <h3>Methods</h3> This study conducted a post-hoc analysis of a quasi-experiemental trial. The intervention group received collaborative care from orthopedic and geriatric departments in Beijing hospital, while the control group received standard orthopedic-led management in five other hospitals. The primary outcomes included three follow-up assessments within one year, focusing on changes in quality of life from admission. Repeated measurement linear regression models were used to compare differences between the groups, adjusting for potential confounding factors. <h3>Results</h3> The study included 2,071 patients with hip fractures: 1,110 in the intervention group and 961 in the control group. Over half of the patients experienced one or more psychological disorders, primarily fear of falling and cognitive disorders. The intervention had no significant effect on patients with depressive states. Patients with cognitive disorder can benefit from a co-management care model. The co-management care model may have a unfavorable effect on patients with high fear of falling. Additionally, it did not impact the quality of life in patients with concurrent depression, higher fear of falling, and cognitive disorder. <h3>Conclusion</h3> The co-management care model can improve quality of life for elderly hip fracture patients with cognitive disorder. Long-term health education for elderly hip patients should be strengthened, especially those with high fear of falling.
