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

Abstract

Abstract 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.
