111 Predictors of Social Participation Outcomes at Two Years after Burn Injury

INTRODUCTION: People with burn injury often experience long-term social participation challenges. A previous study explored demographic and injury variables predicting social participation outcomes after burn injury. This study aims to further examine post-traumatic growth, and physical and psychological symptoms as predictors of social participation. METHODS: This is a multi-center Burn Model System (BMS) study with a prospective cohort design. Adult BMS Database participants from July 2018 to April 2022 were included. Predictors were measured at 12- and 24-month after injury including Post-Traumatic Growth Inventory Short Form (PTGI-SF), Post-Traumatic Stress Disorder Checklist Civilian Version (PCL-C), Patient-Reported Outcomes Measurement Information System (PROMIS-29) Depression, Anxiety, Fatigue, Sleep Disturbance, Pain Interference and Heat Intolerance. Social participation outcomes were measured with Life Impact Burn Recovery Evaluation (LIBRE) Social Interactions and Social Activities at 24-month after injury. Multivariable regression analyses were conducted to assess the association between predictors and outcomes. RESULTS: A total of 158 burn survivors were included with an average age of 47 years and a mean burn size of 19.5% total body surface area. Significant predictors included PCL-C and PROMIS-29 Depression for LIBRE Social Interactions, and Heat Intolerance, PROMIS-29 Pain Interference and Depression, and PCL-C for LIBRE Social Activities. See Table 1 for details of regression results. CONCLUSIONS: Overall, self-reported post-traumatic stress and depression are associated with limited social interactions while heat intolerance, pain interference, depression, and post-traumatic stress are related to fewer social activities. APPLICABILITY OF RESEARCH TO PRACTICE: This study improves our understanding of the multiple and modifiable factors which influence social participation after burn injury.
