Physical, functional, and psychosocial recovery from burn injury are related and their relationship changes over time: A Burn Model System study

Abstract

ObjectiveWhile burn injuries can have dramatic effect on patients’ physical health, they can also lead to intense psychological distress, loss of important social and role functioning, and alterations in outward appearance. We aimed to identify potential leading indicators of recovery in the post-discharge period following acute burn injury and hospitalization. MethodUsing data derived from the Burn Model System National Database, we identified five outcomes of interest measured at four time points (Pre-burn/Discharge, 6 months, 12 months, and 24 months post-discharge), including mental health, physical functioning, community integration, life satisfaction, and satisfaction with appearance. We applied cross-lagged panel analysis to the sample of 1052 injured patients admitted to burn intensive care units. ResultsOverall, there was little mean change in the five measures after the 6-month assessment. A time-varying panel model was superior to a time-invariant model, showing that the process of recovery itself may change over the course of two years post-burn. Physical functioning is an important predictor throughout this period, while satisfaction with appearance is quite predictive of other factors at discharge, but somewhat less predictive later. Overall mental health functioning is less predictive at discharge but at later intervals was a meaningful leading predictor of the other outcomes. ConclusionsRecovery from burn injury is complex and the most important facets of recovery change over time. Future research should focus on developing treatments to help patients adjust to post-burn appearance in the early post-discharge period, and mental health interventions may be effective as patients progress in recovery.
