Mental and Social Health Recovery after Major Burn Injuries: A Burn Model System Study.

内容摘要

Although survival after major burn injury is increasingly common, persistent psychosocial morbidity often remains prevalent, and the relationship between burn severity and long-term psychosocial recovery is less understood. We aimed to evaluate longitudinal trajectories of mental health and social recovery across large burn-size strata to examine whether injury severity differentially influences internal psychological outcomes versus external social participation. We conducted a retrospective, multicenter longitudinal analysis of adults with ≥20% total body surface area burns enrolled in the Burn Model System National Longitudinal Database, using outcome measures available across their respective collection periods. Participants were stratified by total body surface area groups of large (20-49.9%), very large (50-69.9%), or massive (≥70%). Outcomes included Patient-Reported Outcomes Measurement Information System domains of Depression, Anxiety, and Ability to Participate in Social Roles; Community Integration Questionnaire-Social Integration; and employment status assessed at 6-, 12-, and 24-months post-injury. Mixed-effects linear regression models adjusted for demographic and clinical covariables. Among 815 participants, depression and anxiety remained elevated relative to population norms, while social participation improved across all burn sizes longitudinally. Survivors with massive burns demonstrated the greatest improvement in mental health over 24-months, with changes reaching clinically meaningful magnitude, and their community integration at 24-months was comparatively preserved, coming closest to pre-injury burn levels despite lower perceived social role ability and employment. These findings demonstrate that psychosocial recovery over the first 24-months does not worsen in proportion to injury severity, indicating that injury severity alone should not define prognosis. Rather, survival and rehabilitation after massive burn injury can translate into meaningful psychological adaptation and social integration that benefits from sustained, multidisciplinary follow-up across all burn severities.
