Quality of Life and Psychological Health after Recovery From Disorders of Consciousness: A Traumatic Brain Injury Model Systems Study.

Patients with disorders of consciousness (DoC) resulting from severe traumatic brain injury (TBI) may recover consciousness and independence years later. There is a prevailing belief that recovery, when limited to the restoration of independence in activities of daily living, will be accompanied by poor self-reported quality of life (QOL) and psychological health. This perception may influence early clinical decision-making related to the provision of life-sustaining treatment and access to specialized rehabilitation. In this observational study, we utilized data from the multisite TBI Model Systems (TBIMS) to evaluate the outcomes of QOL (Satisfaction With Life Scale [SWLS]), anxiety (Generalized Anxiety Disorder-7 Scale [GAD-7]), and depression (Patient Health Questionnaire-9 [PHQ-9]) in participants who were admitted to inpatient rehabilitation with DoC and recovered the ability to provide self-report on these measures by 1 year post-TBI. Among 887 TBIMS participants admitted to inpatient rehabilitation with DoC (defined as the absence of command-following; 74% male; mean [standard deviation, SD] age = 36.82 [17.87] years; days post-injury on rehabilitation admission = 33.63 [22.51]), 50% regained the capacity to respond to questions on self-report measures at the 1-year follow-up time point. The mean (SD) total scores were as follows: SWLS = 20.38 (7.81), GAD-7 = 4.00 (5.66), and PHQ-9 = 5.22 (5.04). A minority of patients endorsed dissatisfaction (15%) or extreme dissatisfaction (9%) with life, and similarly, only 14% and 16%, respectively, reported anxiety and depression symptoms above the clinical cutoff points. The results were similar at the 2- and 5-year follow-up time points. In summary, at the group level, QOL and psychological health in persons who recover from DoC are similar to those of individuals with less severe brain injuries and to the general population. These findings challenge the assumption that recovery from DoC is associated with poor QOL and psychological health. Clinicians should be aware that patients with a broad range of residual disability after DoC are unlikely to report dissatisfaction with life or have significant anxiety and depression up to 5 years post-TBI.
