Social Interactions and Social Activities After Burn Injury: A Life Impact Burn Recovery Evaluation (LIBRE) Study

Social interactions and activities are key components of social recovery following burn injuries. The objective of this study is to determine the predictors of these areas of social recovery. This study provides a secondary analysis of a cross-sectional survey of adult burn survivors. The Life Impact Burn Recovery Evaluation-192 was administered to 601 burn survivors for the field-testing of the Life Impact Burn Recovery Evaluation Profile. Survivors aged 18 years and older with injuries ≥5% total BSA or burns to critical areas (hands, feet, face, or genitals) were eligible to participate. Multivariate linear regression analyses were used to determine predictors of the Social Activities and Social Interactions scale scores. A total of 599 people completed the Social Interactions and Social Activities scales. Of these, 77% identified as White Non-Hispanic, 55% were female, 55% were unmarried, and 80% had burns to critical areas. Participants had a mean age of 45 years, a mean time since burn injury of 15 years, and a mean burn size of 41% total BSA. Younger age (P < .01) and being married/living with a significant other (P ≤ .01) were associated with higher Social Activities and Social Interactions scale scores. Individual item responses reveal that survivors had lower scores on items related to participating in outdoor activities (30.4%) or feeling uncomfortable with their appearance (32.4% report dressing to avoid stares). Social interactions and activities are long-term challenges for burn survivors. It is important for clinicians to identify patients who may struggle with social recovery in order to focus on future community-based interventions.

Longitudinal Clinical Trial Recruitment and Retention Challenges in the Burn Population: Lessons Learned From a Trial Examining a Novel Intervention for Chronic Neuropathic Symptoms

Long-term trials are key to understanding chronic symptoms such as pain and itch. However, challenges such as high attrition rates and poor recruitment are common when conducting research. The aim of this work was to explore these issues within a long-term randomized control trial using transcranial direct current stimulation to treat pain and itch. This parallel double blinded, placebo-controlled randomized trial was comprised of 15 transcranial direct current stimulation visits and 7 follow-up visits. Participants were over the age of 18, had a burn injury that occurred at least 3 weeks before enrollment, and reported having pain and/or itch that was moderate to severe in intensity. A total of 31 subjects were randomized into either an active or sham transcranial direct current stimulation groups. There were no significant differences between the groups in terms of age, race, education, baseline depression, or anxiety. The median dropout time was at visit 19 (visit 16 [SE = 1.98] for the sham group and visit 19 [SE = 1.98] for the active group). Analysis showed no differences in the dropout rate between groups [χ2(1) = 0.003, P = .954]. The dropout rate was 46.7% for the sham group and 43.8% for the active group. Overall, 45.2% of the subjects dropped out of the trial. Long-term clinical trials are an essential part of evaluating interventions for symptoms such as chronic pain and itch. However, as seen in this trial, long-term studies in the burn population often face recruitment and adherence challenges.

Distinct behavioral response of primary motor cortex stimulation in itch and pain after burn injury

It is still unclear whether chronic neuropathic pain and itch share similar neural mechanisms. They are two of the most commonly reported challenges following a burn injury and can be some of the most difficult to treat. Transcranial direct current stimulation (tDCS) has previously been studied as a method to modulate pain related neural circuits. Therefore, we aimed to test the effects of tDCS on post-burn neuropathic pain and itch as to understand whether this would induce a simultaneous modulation of these two sensory manifestations. We conducted a pilot randomized controlled clinical trial comprised of two phases of active or sham M1 tDCS (Phase I: 10 sessions followed by a follow-up period of 8 weeks; Phase II: additional 5 sessions followed by a follow-up period of 8 weeks, and a final visit 12 months from baseline). Pain levels were assessed with the Brief Pain Inventory (BPI) and levels of itch severity were assessed with the Visual Analogue Scale (VAS). Measurements were collected at baseline, after the stimulation periods, at 2, 4 and 8-week follow up both for Phase I and II, and at the final visit. Sixteen patients were assigned to the active group and 15 to the sham group. Ten sessions of active tDCS did not reduce the level of pain or itch. We identified that itch levels were reduced at 2-week follow-up after the sham tDCS session, while no placebo effect was found for the active group. No difference between active and sham groups was observed for pain. We did not find any treatment effects during Phase II. Based on these findings, it seems that an important placebo effect occurred during sham tDCS for itch, while active M1 tDCS seems to disrupt sensory compensatory mechanisms. We hypothesize that pain and itch are complementary but distinct mechanisms of adaptation after peripheral sensory injury following a burn injury and need to be treated differently.

Review of Burn Research for Year 2014

Management of burn injuries requires treatments and interventions from many disciplines. Worldwide, burn patients suffer from physical and psychological challenges that impact their lives socially and economically. In this review, we will highlight a handful of the numerous articles published in multiple areas of burn care. The areas of burn care addressed in the article are: epidemiology; burn resuscitation, critical care, and infection; nutrition and metabolism; pain and rehabilitation; prevention and firefighter safety; psychology; and reconstruction and wounds.
