BackgroundAlthough burn patients with preexisting mood disorders have been shown to have diminished clinical recovery, acute mental disorders (AMD) are often unrecognized despite a link with post-traumatic stress disorder and social maladjustment later on. This study assessed the clinical profile of a large cohort of burn patients who developed AMD compared to those with chronic mental illness (CMI) and those without mental health problems to assess the impact of AMI on burn outcomes.MethodsAdmission data on 96,451 patients with third degree flame burns was abstracted from the Nationwide Inpatient Sample (NIS) Database from 2001 to 2011. AMD was defined as adjustment disorder (ICD-10 codes F43.2-F43.29) and acute stress disorder (F43.0), while CMI was defined as major depressive disorder (F33.0-F33.9) and bipolar disorder (F31.0-F31.9). Data was compared across three subgroups: AMD, CMI, and patients without any mood disorders. Categorical variables were compared using the Chi-square test, and continuous variables were compared using Student t-test and analysis of variance (ANOVA). Multivariate analysis using the "backward Wald" method was performed to calculate odds ratios (OR) and determine independent factors which increased the risk of developing AMD after burn.Results979 (1%) burn patients were diagnosed with AMD, compared to 5971 (6.2%) with CMI and 89,501 (92.8%) without mood disorders at the time of the burn. Patients with AMD were significantly younger, predominantly male and Caucasian. Patients with AMD had a higher frequency of multiple third-degree burn sites. AMD patients had a significantly longer length of hospitalization and shorter actuarial survival. More AMD patients lacked social or family support, suffered from alcoholism or illicit drug abuse, and had a history of psychological trauma or self-inflicted injuries compared to other groups. After burn, 4.9% of AMD patients developed burn wound infections, 5.0% had nutritional deficiencies, 1.7% had skin graft failure, 0.7% had acute psychosis, and 3.7% had suicidal ideation, p<0.05. Multivariate analysis identified age 10-39 (OR 4.6), alcoholism (OR 1.4), drug abuse (OR 1.9), psychoses (OR 1.4), and total body surface are (TBSA) 10-39% third degree burns (OR 1.8) as independently associated with developing AMD, p<0.005.ConclusionThe development of AMD in burn patients is associated with poor clinical outcomes including longer hospitalization, decreased survival, and increased complication rates. Premorbid psychopathology, substance abuse and age were associated with a higher incidence AMD after burn than was the severity of the burn wound itself. Routine screening for psychological symptoms of AMD should be performed in all burn patients to avoid increased rates of short and long-term morbidity and mortality.Copyright © 2016 Elsevier Ltd and ISBI.
